When does it make “cents” to stop outsourcing and build an in-house automated finishing system?

Good question. It starts with knowing how much you currently spend and how much throughput volume you may need in the future. How much do you spend now on outsourcing your part finishing?

Many manufacturers outsource some to all of their finishing, be it powder coating or liquid finishing,  because they want to leave it up to “experts,” don’t have space for a system, and desire to concentrate on what they do best, like fabricating and assembling final products. They could also have unusual or rarely needed parts that simply cannot be done on their in-house systems.

Let’s just assume you are outsourcing your finishing because your need for it started out small but has grown over time. At this point, you mainly do it because, “It’s what we’ve always done.” Maybe it’s time to start working on a business case that would let you know if you’re ready for your own system!

Let’s also throw some hypothetical numbers at this issue.

powder coating gunImagine your outsourcing of finishing has grown over the years to about $1 million per year with local (or maybe distant) custom-coaters. How much money could an automated, in-house system save you per year that would justify the relatively large capital expenditure?

As a starting place, would it make sense that you would at least save the gross profit margin your custom-coaters are currently collecting from you? (For this article, we’ll ignore the fact that bringing finishing in-house is also likely to decrease total WIP, greatly decrease re-work, improve turn times, and save on transportation costs, too.)

Obviously, that gross margin varies depending on product, unique challenges, etc., but let’s sling a guess at it.

IntelliFinishing’s parent company (Kasa) operated a relatively large fabrication and coating company called KasaFab for many years before selling it to a local manufacturer.

Our former VP of that company still works for Kasa, and he said, “On small-quantity powder work, we would charge a pretty high margin of 60 to 65%. On large-quantity work, we would shoot for 50 to 55%.”

Now, maybe your custom coater doesn’t get as much margin as our former KasaFab operation. This might be because there are more competitors in your market. After all, KasaFab (now Vortex Fab) is the only large fabricator for at least 50 miles or more in any direction. It is in the middle of Kansas!

Meanwhile, I’ve also heard it said by longtime experts in the field that you should be able to save at least 20 to 40% by bringing coating in-house.

So, let’s start conservatively and imagine a savings of only 25% to represent the gross margin your custom coater is charging. This means a new automated system should save you at least $250,000 per year, assuming the previous assumption of $1 million per year being outsourced.

savingsDepending on the types of product you need coated, even a relatively traditional monorail could be paid for in about two to four years for this amount of savings. After that, it would be savings that go to your bottom-line profits. Most simple monorail systems likely cost between $500,000 and $2,000,000, but this is entirely dependent on process requirements for pre-finish steps such as shot-blasting, washing, and dry-off ovens, as well as for the type of booths and cure ovens and specific conveyor requirements for the part dimensions and weight considerations.

However, for an IntelliFinishing System, it’s a little more complicated. Our systems are much more flexible than monorail systems in that we can accommodate processes for a much wider variation of parts. IntelliFinishing systems use a friction tube conveyor that allows for control of every section of track, so every carrier can, in effect, be given a different process recipe (video: www.intellifinishing.com/part-recipes).

We also have a sophisticated software control system to integrate each independently operated section of track to keep items moving as per the recipe, yet also keep carriers from bumping into each other. Consequently, the conveyor and controls are somewhat more expensive than monorail systems, but often highly competitive with power & free chain-based systems.

Therefore, most IntelliFinishing systems installed have cost between $1,500,000 and $10,000,000, with an average of about $3,000,000.

But, here’s the kicker! An IntelliFinishing System is usually way less expensive to operate. Here’s a link to an article we recently published that explains why this is the case.

Since any custom-coater you are likely to use is unlikely to have an IntelliFinishing System, any manufacturer who installs an IntelliFinishing system is very likely to save much more than just the gross margin.

If the IntelliFinishing technology makes sense for your company based on the parts needing finished or your volume, then the “$1 million outsourcer” example we have suggested could save up to 60% compared to outsourcing. Thus, $600,000 per year saved could finance a much more economical IntelliFinishing system very quickly!

Of course, there may be other considerations. Do you have space for a system? If so, great! If you’re unsure, talk to us. Our system often saves 25 to 40% in footprint depending on the nature of your parts and processes.  If you need to build or lease a new space, you will obviously need to include those costs in your calculations, too.

calculationsUltimately, this is just a first-cut calculation to begin the process of considering a new finishing system. If your calculus indicates you might benefit from a system, the next step is to start finding a vendor to draft up a layout and determine a budgetary or formal quote.

But, before you decide to go with any one system, I’d also like to suggest you figure out your likely actual costs of having and running a new finishing system. You should do this from the ground up. The costs would include system and building utilities, building lease or purchase costs, depreciation considerations, manpower to operate the system, possible restructuring of existing processes and flow, and, of course, paint or powder costs, maintenance, etc.

If you are ready to consider bringing finishing in-house and are wondering if an IntelliFinishing system might be a good fit for you, check out our website and watch a few of our videos, then contact us. We will be happy to help you not only figure out a potential system, but also to help you with your cost justifications.

Now May Be the Perfect Time to Invest in a New Finishing System

Choosing to upgrade your finishing system is always a massive undertaking – and the current period of uncertainty may make it seem even more overwhelming.

However, the current climate may be the perfect time to take the leap.

Why? Let’s dive in.

Why the Push Toward a New Normal Offers Exciting Opportunity

There are several central reasons why, even as the COVID-19 pandemic continues, investing in a new finishing system may be a strategic and valuable move.

An Upcoming Spike in Demand – And Pricing

First, many companies have put off key projects in the wake of the COVID-19 pandemic, opting to save money and focus on core aspects of their operation until a more settled “new normal” arrives.

Spike in DemandHowever, this dip in demand has us here at IntelliFinishing, along with our system partners, raring to go.

We’re hungry to keep our staffs busy, and pricing could reflect that.

But this window won’t last for long. As the reopening picks up momentum, backlogs will start to grow once again, and pricing will level out to normal levels. As confidence in this march toward business as usual grows, those who chose to sit it out and go without key upgrades for the time being will be left facing higher prices and longer project installation turnaround times.

Get Prepared to Be Lean, Agile and Productive in the New Normal

In addition to this likely spike in demand coming down the pipe, investing in a new system now can better prepare your company to emerge into the new normal lean, agile and productive.

By closely examining and evaluating your facilities and ways to eliminate waste, you can emerge stronger than your competitors and ready to meet heightened demand.

Waste on finishing can include the outsourcing of finishing – an expensive cost that most “experts” say could be reduced by at least 30% if brought in-house. Further, with an IntelliFinishing System – due to our lower costs to operate – these savings could be over 60%.

Finishing: Outsource vs In-HouseOf course, each situation is unique and would require in-depth analysis, but why not check into bringing your outsourcing in-house? (More on this topic in the coming weeks!) You’d also likely see far less rejects and defects, a reduction in transportation costs, faster turn times, less WIP, and better finish quality.

Even if you currently have a finishing system or multiple systems, they are likely to be much more expensive to operate or fall short of optimal needs than a new system.

If you wander by your finishing system and see high levels of work in progress (inventory) stacked around the system due to the requirement to batch like items together because of the inflexible systems you own, you are wasting money and labor.

If your ovens and your chain flood your building with heat because of large part window openings and chain/carrier heat sink transfer, you are obviously wasting natural gas, as well as possibly electricity to fan or cool your facility.

If your current system can’t keep up with production or has a part window that limits your product sales, it’s time to consider something better.

Finishing System Layout BlueprintAnd, finally, if you have or are considering a system that consumes a larger facility footprint than an IntelliFinishing System can provide, you are missing an opportunity to use that space for other revenue producing activities or to have a smaller facility that costs less to build, own or lease.

Why consider a chain-based automated finishing system that is inherently dirty, contributes to finish contamination, is difficult to adapt per part or to innovation, and is wasteful of energy?

Visit an IntelliFinishing System Yourself

Finally, with many employees and leaders working remotely, it could be a prime opportunity to visit a cutting-edge, IntelliFinishing flexible automated finishing system, powder coating system or liquid coating system in your area to get an idea of exactly how investing in one could benefit your operation.

Let IntelliFinishing Be Your Guide

At IntelliFinishing, we’re committed to helping you find the best solution for your unique needs and operation – even if that means not upgrading your system at this time or recommending something more traditional if that’s the best fit.

However, if upgrading to an IntelliFinishing Automated System can bring you real value and efficiency, this could be the perfect time to get to work.

To learn more, contact IntelliFinishing today.

Automated finishing systems are tremendous drivers of efficiency. However, there are often areas of improvement. Let’s explore how some traditional designs fall short in this area and what you can do to double your automated system’s throughput capacity.

Chained to Design

Breaking free of the Chain Finishing SystemTraditional, chain-driven automated powder finishing systems are usually welded together and set to function at a certain line speed. Because of this, it’s difficult to expand the throughput and increase production. You could try to increase the line speed, but then you’d be increasing the speed of all the system processes. In most cases, that means disaster.

This approach would also bungle the final cure step, which is usually designed for a specific length of travel time through a certain range of the oven. Trying to speed that up would result in the entire process being incorrectly completed.

There are more optimal solutions.

Monorails Limit Expansion

Because most automated powder finishing systems are monorails, it’s impossible to just bolt on more oven capacity.

Similarly, one can’t simply attach a new wash loop or additional booths to a monorail. If you want to change the functionality or design and double the throughput, that typically means having to build a whole new system.

Again, it’s easy to understand why this isn’t the simplest or most cost-effective approach.

The Costs of Power and Free Systems

Power and free automated powder finishing systems are more flexible in their design. Additional system loops and spurs can be added, but there are still associated difficulties and costs.

Mating new P&F track can be significantly challenging and often leads to major downtime events. If the system is down, it’s obviously not producing anything, which leads to extra costs.

You guessed it – there’s a better way.

Enter IntelliFinishing’s Automated Finishing Systems

Increase Capacity - Double Finishing System ThroughputAn IntelliFinishing automated finishing system is the perfect solution for having a modular, modifiable finishing system that can double its throughput.

The systems are built with more of an “erector set” design in mind. During the initial building of the finishing system, expansion points can be introduced to compensate for future growth in throughput needs.

Possible bottlenecks (usually the oven capacity) can be identified and assembled with track switches for the eventual addition of other loops in the system. This way, when there’s a greater need for a certain process, it’s easy to build out the new spur, add the additional process and tie the system back together with minimal downtime and relatively low cost.

Double Your Throughput with IntelliFinishing Automated Finishing Systems

These innovations are what make an IntelliFinishing system leaner, more cost effective in the long run, more cost effective to operate each day, and better able to meet many of the changes and innovations as systems -class company with unparalleled expertise in the powder-finishing industry. As your company and your needs expand, our systems will grow alongside you.

You can waste money on purchasing new systems every time you need more throughput, or you can upgrade to an IntelliFinishing system and work with our experts to find the best solution for your unique needs and future-proof yourself in the process.

JR Custom Metal Products, an existing IntelliFinishing customer, has once again leveraged the power of IntelliFinishing to elevate overall operations and efficiency. (View the video of the JR Custom IntelliFinishing system.)

JR Custom is committed to competing and succeeding on quality, yet has found a way to ensure that quality is consistent while also promoting new efficiencies. Recently, the company added a Parker Ionics Prime Coat booth to its existing single-coat finishing system.

Overview and Challenges

While JR Custom’s efficiency and throughput were already high as a result of their use of an IntelliFinishing system, installed in 2016, the company was seeking a way to efficiently offer a two-coat powder coating option on their single-coat system due to increasing customer demand for two-coat (prime and topcoat).

JR was already doing a two-coat process with their IntelliFinishing system when needed, but it required parts to move through the entire finishing system track twice, slowing throughput considerably.

The new addition needed to add this prime coat option in-line with the system and be installed with minimal downtime.

The Solution: A Parker Ionics Prime Coat Booth Fitted into the Existing System

JR Custom Paint Booth AdditionTo address these needs, JR Custom chose to fit a new Parker Ionics Prime Coat booth into the company’s existing finishing system.

The booth was installed and integrated with the existing recipe software with an insignificant amount of downtime. The booth was positioned directly after the existing dry-off oven. For parts needing to receive a primer coat as part of their recipe, the parts are heated a little longer and hotter than normal in the dry-off oven, then immediately sent into the prime booth while hot. Pre-heating products before they are primed is a process called flocking.

Once in the booth, doors on the booth close behind and in front of the part, so the booth’s airflow system works properly – meaning the booth doesn’t pick up ambient heat from the nearby dry-off oven that could create an updraft that would tend to float powder up and out of the booth.

Integrating a door system to the existing track flow and software was extremely important to make the prime booth function properly.

After being primed, the product can then move along the remainder of the existing finishing track system for the top-coat application, final curing, cooling and unload.

Items that do not require a prime coat simply flow through the prime booth without stopping, as they would have on that section of track before adding the prime booth.

The Result: Added Efficiency and Options

With the prime coat booth added to their existing system, JR Custom has one more service and recipe option for their IntelliFinishing recipe-driven automated finishing system.

“Now, I can offer my customers options on finish longevity,” said Jorge Martinez, Co-Owner. “A single-coat powder finish on my system routinely achieves about a 1,000 hours or more (depending on the powder and other options chosen) salt spray, while my two-coat process can achieve over 2,000 hours of salt spray test.”

“The best part is that we can simply toggle from a recipe that allows for one coat to a two-coat option without any other complications and with a system that maintains a high level of throughput capacity.”

JR Custom’s system flexibility allows for an extremely wide assortment of parts to be finished via the recipe system. They currently have hundreds of recipe options on their system, including options for shotblast or no shotblast, speed within the shotblast, number of times through the blast, pressure settings per stage in their wash, wash stage on/off options, unlimited time and temperature settings for the dry off and cure ovens, and many other possibilities.

Ultimately, the goal of JR’s system is for each type of part to be finished optimally based on its unique cure and finish requirements.

JR Custom’s IntelliFinishing System also saves money on utilities (up to 40%), because the conveyor rides above the ovens. There are no chains or carriers riding through the oven to soak up heat. There are also doors on the ovens to help keep the heat contained, as well as other energy-saving and insulating properties.

Thanks to its IntelliFinishing System, JR Custom Metal Products has a modular system with the ability to expand to meet changing process or throughput needs while also being cleaner, quieter, and much less expensive to operate than a comparable traditional automated system.

In the world of planning, there’s always the chance that something goes awry. These best-laid plans hit snags much of the time because of unforeseen challenges, especially during a pandemic. IntelliFinishing recognizes building automated finishing systems is a complex process—one with lots of specifications, including process equipment, paint application, conveyors, controls, the footprint, utility requirements and more.

While these projects have lots of moving pieces, we do everything within our power to meet our client’s expected operational date for beneficial use. We want every organization considering an IntelliFinishing system to understand our processes and commitment to their desired completion date as well as the most common reasons for delays.

Experience Matters

We have a wealth of experience on our side in installing automated finishing systems big and small. One of our largest systems contains a mile of conveyorized track and our smallest – just a few hundred feet! No matter the size of the job, our customers receive the same care when it comes to timelines. At IntelliFinishing, the priority to Meet Deadlines is only secondary to Safety and Quality in our stated and adhered to company values.

IntelliFinishing Customer Testomonials

We’re proud to say that we’ve never had a customer unhappy with our efforts to complete a project within the agreed-upon timeframe. However, that doesn’t mean that all the planning and work don’t encounter unexpected delays. Below are some real examples, however we have not cited actual projects names or involved vendors…because we love our customers and suppliers!

What Are the Biggest Causes of Delays?

Our team tracks what causes delays or problems on every project so that we can be better prepared for the next job. 2020 has, of course, been a complete curveball! The strain of the pandemic on supply chains, safe workspaces, losing workers for a time due to infection and more have certainly had an impact. Beyond the challenges of COVID-19, here are the most common causes of delay for projects we’ve installed.

weather iconWeather

It’s unpredictable and outside of anyone’s control. Weather doesn’t usually slow down the building of a system, rather it often affects the building site.

On a recent project installed near Atlanta, the area received substantial rainstorms for weeks, creating a massive mud pit in the area that was the build spot. Since this was a new addition to an existing building, a slab was necessary to support the walls. The rain delayed the building contractor for weeks, preventing the delivery of the system equipment. In this case, the customer had been outsourcing their finishing needs prior to deciding to install an IntelliFinishing system, and we were able to complete the installation once the addition was available in a relatively short timeframe.

Another unexpected weather-related example includes an installation in an existing building where the customer experienced a roof leak around the ventilation of and above their liquid booths. This leak was causing problems with operating the system at regular capacity and meant the system could not be officially approved as per the project contract. We could not properly repair the roof ventilation until the rain stopped. However, the customer was effectively using the system, working around the leak problem, but we didn’t receive final approval on the project until the repair was completed – a few weeks after “the unexpected monsoon season”.

purchasesEquipment Purchases from Vendors Not on the Main System Contract

Companies often purchase items related to the finishing system apart from the main system contract. Examples include shot blasts, booths, application equipment, robotics, etc.

In a recent installation, we learned about two months into an eight-month project that vendors supplying an inline shot blast as well as those supplying system robotics, would be unable to meet their delivery deadlines and thus it delayed our installation schedule. To be absolutely fair, this situation arose, in no small part, because the procurement and negotiation process between the client and these vendors went longer than expected – thus delaying their delivery turntime schedules. Further exasperating these same delays were COVID-related supply chain slowdowns from overseas and other areas.

With these extenuating circumstances, our customer graciously removed the liquid damages clause that were a part of our contract with them. Meanwhile, we were able to meet our equipment arrival timelines and find workarounds for the delays of the other vendors. The system was up and running only a month or two later than originally expected. Ultimately, the client is extremely happy with the installation process and with their system.

utilitiesLocal Licenses and Utilities 

Ensuring a site has the appropriate licenses and utilities is integral to the installation. These aspects of an installation are usually the responsibility of the client, but since we act as general contractor for the system, we are often very involved in helping clients with these outside agencies. However, a few years ago, we worked with a client serving as their own general contractor. Unfortunately, they made an error in ordering the appropriate capacity of the natural gas line. It simply wouldn’t meet the requirements of the system equipment, resulting in a several-month delay. Fortunately, the system was able to operate its multiple cure ovens at half capacity after installation and ultimately, they obtained the proper sized gas line to feed all of their ovens.

Another project also related to delays due to utilities: In this case, the whole project was delayed due to the electrical company not installing their switchgear equipment when requested. As was their responsibility, the client requested a specific date for installation and many other tasks in the project were contingent on hitting that date. Utility companies, however, don’t always meet their requested install dates – and in this case it caused a cascade of task rescheduling.

constructionBuilding Site Construction Delays

Construction, whether a new build or a remodel, is infamous for missing deadlines. A million things can go wrong with materials, labor, inspections, equipment and more. While we all know that construction timelines rarely meet expectations, the delays impact the system project, nonetheless.

other delaysReally Unexpected Situations 

The last category is everything else that you would never expect, but it’s happened. For example, we had a client who suffer a cybersecurity attack on their ERP system! Without their operating system, they couldn’t even carry out routine functions. They couldn’t even email us or send us their purchase order for several weeks! This actually happened over their holiday shutdown and for a week or two after it, so it wasn’t presumably during their busiest time of year, but it sure was frustrating for them while it was happening. Once they were able to restore their systems, we received the long-expected purchase order in plenty of time to start their project’s march to completion.

Things Rarely Go as Planned, but IntelliFinishing Adapts

There are so many possibilities of plans going askew that are outside of our control. We’ve come to learn that delays happen, so we adapt to ensure we do everything in our power to meet customer timeline needs.

At IntelliFinishing, we want to do more than just meet deadlines; we want to exceed customer expectations every time. The response from customers on our installation processes is overwhelmingly positive! As Bill Dunn, CEO of Manufacturing Resources International, said, “Everything was very efficient, and they were great to work with. It was amazingly smooth and painless.”

See How Our Systems Work

Our automatic finishing systems for liquid and powder coating are remarkably different. With a unique friction-tube conveyor and smart controls, it’s more efficient and process flexible than traditional chain-based systems and may take up a significantly smaller footprint, too. See how it works by watching some of our videos.

Are you employing an outdated technique in moving parts throughout your automated finishing process?

Daisy chaining parts, when products are suspended from hooks, can cause swaying of parts, particularly as the parts move through turns, stop or start, or change elevation. That sway can also be initiated by workers who are trying to “catch the moving line” when dealing with chain-based, conveyorized, overhead finishing systems.

In power and free systems, sway can also be introduced when part carriers abruptly stop in place or switch from one chain track to another, particularly if those tracks are traveling at different speeds.

Swaying parts in the process of finishing parts adds up to lost dollars, because it forces parts to maintain greater clearances from each other as they travel through the system to avoid crashing into one another or, worst-case, falling off the line. Crashing into each other can certainly mar the finish, if not the part itself! Falling off the line is also very problematic!

There’s a better way to decrease sway in chain systems and increase part density.

Variable Frequency Drive Controlled Carriers Bring Measurable Benefits

Motor Controlled by VFD, Variable Frequency DriveWith an IntelliFinishing system, part sway is greatly reduced via the use of variable frequency drive, or VFD, control.

In these systems, the speed of each carrier on a section of track is independently controlled by a small motor that is VFD controlled. This VFD allows carriers to smoothly accelerate and decelerate, reducing the inertial forces that lead to excessive swaying of parts.

An IntelliFinishing system also allows parts to stop for load, unload, masking, blow off, or yes, even the finishing processes. Carriers can also speed up or slow down as may be needed or required per section of track. For example, in a non-process section of track carriers may move at speeds as high as 40 to 65 feet per minute (considerably faster than the fixed line speeds of most chain conveyors), but then slow down to under 10 fpm for a wash process or as they enter an automated finishing booth. The carriers might also index forward in an oven, as another example, in order to achieve a specific amount of time in that oven while other carriers in the oven have other time allotments for drying off or curing.

Racking Method Significantly Effects Productivity

Many users of IntelliFinishing systems choose to preload parts on removable loadbars and then hang the entire loadbar on the system from a carrier that is stopped in place. This avoids having loaders chasing after a moving chain to load the parts. After load, the carrier moves at a variable speed (basically as fast as possible) to the next step or to catch up to the carrier in front that may be waiting it’s turn in the wash or shotblast.

As a result, and especially when combined with more solid frame racking, many more parts can be hung in the same processing part window for an IntelliFinishing system.

Dense Part Racking for FinishingFor most systems, it takes the same amount of wash spray and time in the oven or booth to process a dense set of parts hung on a carrier compared to a lightly loaded carrier. This means that, when you can get greater part density, you can boost production without decreasing efficiency, which translates to heightened productivity. For a recent client, we were able to calculate a 20% increase in throughput per hour, simply by assuming the capacity to increase the density of parts on an IntelliFinishing System compared to traditional finishing system carrier loads.

The racking system is also a key inflection point on the journey to greater efficiency, and it’s common to question which might be right for your needs. While that will ultimately depend on the parts, in general, racking that locks a part in place is better to minimize part sway, no matter whose conveyor you use.

Of course, in powder coating, grounding through the racking is an important consideration. In this case, racking that has clean connections to the carrier or loadbar will transfer ground best and thus insure a better finish with less powder waste.

Variable frequency drives, or VFDs, provide efficient use of power, allow for productivity and control under different types of torque loads, and more.

After some brief information regarding motor controllers and torque loads, let’s explore the ABCs of these beneficial solutions – the applications, benefits and cost savings.

Different Types of Motor Controllers and Torque Loads

The core types of motor controllers are across-the-line motor starters, which come in full voltage non-reversing and full voltage reversing, soft start/stop controllers, and VFDs.

Max Throttle

Across the line, full voltage starters send full voltage, typically 480VAC, to the motor – usually with an accompanying “clunk” that can even dim the lights. Essentially, these motor starters go “full throttle” as soon as they’re turned on.

That issue is slightly alleviated by soft start/stop motor controllers, which use a solid-state electronic device to ramp up the speed of the motor from 0 to 100% over a predetermined amount of time. It works the same way as it stops. This results in less wear and tear on the motor, but these still always go to full speed.

VFDs - Variable Frequency DrivesFinally, there are VFDs. Mountable in a motor control center or standalone, VFDs allow for the adjustment of motor speed over time, providing finer control while still realizing the benefits of less wear and tear on the motor.

There are also two central types of torque load. Constant torque loads exhibit roughly the same requirements, regardless of operating speed, while variable torque loads exhibit torque requirements that rapidly increase alongside machine speed.

In constant torque load applications, energy use is roughly proportional to speed. In variable torque load applications, energy savings aren’t linear.

Applications, Such as Finishing Systems, Benefits, and Cost Savings

In comparing soft-start/stop controllers to VFDs, SS controllers are primarily used for energy savings and to prevent excess wear and tear on equipment.

However, in applications such as an IntelliFinishing system, VFDs provide those same benefits while also offering the ability to adjust speed as necessary and to smoothly accelerate and decelerate carriers of parts as they travel through various sections of a system.

Motor & CarrierUltimately, using a VFD on each motor controlling a section of friction tube conveyor on an IntelliFinishing system allows users to increase part density per carrier. This means more throughput in less time. This could amount to as much as 20% more throughput! Combined with the fact that most IntelliFinishing systems are monoplane in design, there are simply far fewer chances parts will bump each other as they wander through pressure washes, shot blasts, ovens, and booths for the typical finishing system set of processes.

Of course, it’s possible to use VFDs on indexing monorail systems or power & free chain systems too and this would greatly help with the amount of part sway often seen on these systems. That said, when a carrier of parts de-dogs or dogs from power & free conveyors, the inertial forces may still cause parts to collide if sufficient spacing between parts isn’t considered.

For an IntelliFinishing system, carriers can move at varying speeds per section, come to complete stops, and even reverse direction if desired (perhaps for a deadhead turn or to back up into a spur that may be a touch-up booth or for systems designed with shuttles that allow parts to enter a process and then back up out of that process when done.)

There are many other cases in which a VFD can provide measurable benefits to finishing systems and process equipment, such as on shotblast and wash motors.

Though installation costs are higher and there are other special considerations, such as more training for techs performing maintenance and special considerations to take into account, the added flexibility and easing of wear and tear on motors, plus the increased throughput can alleviate those costs over the life of the system and provide significant ROI.

IntelliFinishing is a complete finishing systems provider of automated powder coating and liquid paint systems that offers several unique features and benefits. The number one benefit of IntelliFinishing Systems is that they can paint a much wider range of products than traditional chain-based finishing systems. However, they can also provide unique benefits if integrating robots into the finishing process.

By integrating robots into your paint system, you can increase the quality of your finishes, reduce labor, improve safety from hazardous painting environments, reduce waste material, and increase speed, productivity, and system uptime. Robots are most often used in applying finishes, but they could also be used for loading, unloading, and other processes.

One of our customers, Anthony Wasson, Manufacturing Engineer at Hyster-Yale, explains that they have been using robots in fabrication and welding for quite a while; however, for their recently installed IntelliFinishing system, they used robots to apply a finished powder coating on their forklift parts for the first time.

Robots for Precise Finishing“Automating the coating process provides many benefits such as reduced labor, consistent quality, improved throughput, control over powder usage, and less waste.” Although, using robots sometimes presents challenges and for Hyster-Yale their biggest hurdle is part programming. “At this plant, we produce a wide array of products so many of the components we are powder-coating have many variants. Programming each specific robot path takes time and requires individuals with a very special skill set,” explains Wasson.

“Even though you can do offline programming, you still need to verify and fine-tune your programming with physical parts.” Luckily, with their IntelliFinishing system, moving carriers in reverse is extremely simple and can be done by one person.

“Our typical process starts with a roughed-in of the program that is completed off-line, next we step through the program with a physical part in teach mode, then run the part in full speed mode without spraying powder, and finally run the part in production mode and apply the coating. The start of each step requires you to move the carrier back to the beginning position. Doing this same task with a power & free conveyor would require much more effort and multiple people. With the IntelliFinishing system we can back up the part to just prior to the booth as often as we want since the carrier can go either direction. You cannot back up with chain conveyors.

Also, with the part continuously moving through the application window, programming requires you to advance the part to reach designated planes. The conveyor then needs to tell the robot when it is clear to move to the next set of points.”

“This ‘stop & go’ feature of the IntelliFinishing conveyor can be controlled for only that section of conveyor and in very precise increments. Whereas a conventual conveyor system would require turning the chain drive on and off which would not be as controlled and could impact other parts of the system.”

Paint Robots Used in IntelliFinishing SystemAnother customer, Bret Albers, Owner of Albers Finishing & Solutions, recalled their experience with using robots for their liquid painting system. He explains the biggest benefits of using robots are the consistent quality and quicker throughput, “The end result is minimal time in the booth without sacrificing finish quality.” Additionally, he explains that the IntelliFinishing system integrates extremely well with the robotics, which makes it easier to operate, control, and visually see what’s going on with the flight bars.

Like Wasson, Albers also recalls the biggest challenge of using robots in finishing is programming time and testing of new products. Regardless, however, the consistency the robots provide is unmatched and when the expected volume of similar parts is worth the programming time, the outcome is higher quality finishes with less cost per part and in less time and labor.

We have also installed IntelliFinishing systems that use robots or robotic machines for loading, unloading, and in other finishing processes. Using a friction-tube conveyor allows for carriers to literally “stop on a dime” or travel forward and backward with a consistency that is very useful when integrating robots that do any sort of repetitive activity.

Adding an automated finishing system to your operation can have a tremendous impact on efficiency, productivity and quality – and that’s why you’ve made the choice to invest in an industrial finishing system that matches your unique needs.

It’s also critical to get it right the first time and ensure the process results in a finishing system that not only delivers on its potential, but is ready to scale alongside your organization.

High Vis Visitor on Site VisitHowever, all customized automated finishing systems are expensive, likely costing your organization anywhere from $1 million to many millions in capital investment. While this investment will result in significant ROI and a lower lifetime cost of ownership, it’s still important to go see systems at work, especially if you don’t currently have an automated finishing system, before you even fully define your specifications.

So, when should you start your tour of systems currently in place and delivering benefits in real-world operations? The answer is as soon as possible.

Key Considerations to Help You Evaluate Systems You Visit

While seeing any system may help you understand how one might best fit into your organization, try to see one that:

  • Seems to process parts that are similar to yours
  • Uses processes that you’d likely want in your own system
  • Has throughput levels about the same as you may need to hit your goals

But, even more importantly, don’t get locked into the traditional paradigm of an overhead, chain-based monorail or power-and-free conveyor.

Make a conscious effort to see something newer, more flexible and more modular, which can give you a better idea of the possibilities innovations have brought to life in automated finishing systems.

The IntelliFinishing Difference – See It for Yourself

IntelliFinishing automated finishing systems are unique and offer advantages that can’t be matched by traditional chain systems.

They provide recipe control per carrier, empowering you to finish a much wider variety of parts on the same system and let the recipe dictate the optimal process for each carrier of parts processed.

IntelliFinishing Automated Finishing SystemThis allows you to cater to parts that require longer cure or paint times than others. Have extra-long parts that need to be finished in a relatively small space? A shuttle system can help to avoid large radius turns. Do you feel like your processes could change over time? IntelliFinishing systems can expand or be modified, and they’re never stuck at one speed or inextricably linked to every other process.

The earlier you can see automated finishing systems in action, the better. Even if you don’t ultimately choose an IntelliFinishing System, you are likely to make a more intelligent final decision, and you’ll certainly learn something.

Many of the systems we’ve installed are highlighted on our website in video clips. All of those systems often allow us to bring visitors. We also have many other systems that may be very similar to your needs that we haven’t captured on camera.

Ovens that leverage infrared light, or IR ovens, are commonly used in finishing systems to speed up the cure time for a range of finishing processes, including liquid paint and powder coating.

However, IntelliFinishing automated finishing systems don’t typically use IR ovens. Why is that?

IR Ovens Excel under Specific Conditions

Infrared heating of parts is best when the ovens can “see” all part surfaces. Additionally, the substrate metal needs to be thin enough to transfer the heat through to the unseen (by the IR oven rays, at least) geometries of the parts.

As a consequence, you’ll often see IR ovens used for parts that are thin and have wide areas of flat geometry, such as sheet metal items.

IR Infrared Oven to Cure PartsImagine sheet metal designed to cover appliances, for example. If the IR rays beamed at the parts can reach all (or nearly all) of the surface, the IR oven can heat the product up sufficiently to cure the part in both liquid and powder applications.

However, if the parts have boxy enclosures, turns or simply complicated dimensions, IR may not be able to heat up the parts uniformly. While this may not be a problem for some liquid applications, as liquid usually cures on its own even if not fully heated to the recommended force cure temperature or time, issues can arise depending on where the “undercured” areas are.

Further, powder finishes are much more finicky and require heating to a relatively hot temperature and for a specific amount of time. Any powder that is undercured is simply not going to form into the proper coating and is subject to failure and separation.

So, if you have flat panels to paint, large, visible surfaces or just relatively thin parts that are able to transfer the surface temperature into the shadowed crevices of the part enough to cure them appropriately, then an IR cure oven should certainly be considered, potentially in conjunction with a convection oven.

IntelliFinishing Finishing Systems Are Geared toward a Wide Variety of Parts

Part Recipe for Automated Paint SystemsSo, with all that said, why hasn’t IntelliFinishing done many systems that use IR cure ovens? It’s certainly not because we view IR ovens as inferior – it’s because our finishing systems are best utilized by companies that have a wide variety of parts and, therefore, require different recipes per part.

Part-coating systems that utilize IR ovens are usually (although not always) set up to handle a narrow range of part types and geometries. If that applies to your operation, you can probably get by very well with a monorail, chain-based overhead conveyor. In other words, a traditional system will work.

It will also require a lower initial investment than an IntelliFinishing System. This is why, in discussions with prospective customers who need to finish widget-type products or lots of flat panels, we recommend a more traditional system unless they have other process needs that demand recipe controls or space-saving layouts.

IntelliFinishing Automated Paint System Oven Finally, IR curing isn’t predictable in the way a convection oven can be. In order to determine exactly how long a part must cure in an IR oven, the specific parts must be tested in actual IR ovens or confirmed as viable by another organization that cures very similar parts.

So, no matter what IR oven supplier you are talking to, you should inquire about the capability to take your parts into their laboratory and figure out the ideal cure timing and oven specifications required.

The bottom line is this – IntelliFinishing systems are ideal for operations needing to finish a wide range of parts with different recipes, while a more traditional system with IR curing capabilities could be perfectly fine for applications without such variety.
