EVS Metal is proud to be one of the most trusted precision metal fabricators in the U.S. And although we focus much of our company activity around processes like laser cutting, bending and forming, there are entire areas of the company dedicated to other aspects of our business, including engineering, complex and value-added assembly, as well as metal finishing.
Finishing may not be the main focus of what we do, but these capabilities are still very important to our overall success, especially as it pertains to jobs that require us to fabricate a product that ships straight to the end-user, such as an interactive kiosk or vending machine. When we fabricate an end product, it must look truly finished in order for it to get out the door. One of the ways in which we ensure this is via powder coating. Last week, we gave an overview of the different powder coating processes. Today we’ll dig a little deeper into the details of what they entail.
What are the two main types of powder coating?
There are two primary powder coating categories: thermoplastics, which can be remelted into a liquid state; and thermosets that never leave their solid form. Both use a range of polymers, including fusion-bonded epoxy, polyurethane and polyester, just to name a few. As might be expected, thermosets are the best choice when a product will be subject to high levels of heat, as they are unlikely to melt once cured into their final shape or form. Thermoplastics, on the other hand, are best for applications where cosmetic finishes are desired but durability isn’t quite as much of an issue. In the end, neither is better and both are needed and respected in the powder coating world.
Why use powder coating over other finishing processes?
Besides the lower levels of VOCs emitted — especially in comparison to paint — powder coating has other advantages too. It can produce much thicker coatings than liquid paints, and those coatings are also more evenly spread, especially in terms of horizontally- vs. vertically-coated surfaces, which means creating a smooth surface is fairly simple to do, without bubbles or visible paint lines. Powder coating allows color blending to be done right on the item itself.
Because of the flexibility and durability of powder coating as a finishing process, there is near-constant growth in the category. Global demand was about $5.8 billion in 2010, is expected to top $17B by 2025. As a leader in manufacturing, EVS Metal will continue to invest in the skilled operators and equipment required to meet the needs of our customers across North America whose projects are best completed with the latest advances in powder coating techniques, materials and machines.
