In an earlier blog we talked about how fabricated products make the world go round. While we at D+M Metal Products are proud of the work that we do, we realize that our work is often an early step in the process of making the finished products that people see on the shelves in stores. They may be further modified or attached as pieces of larger items. Often our products leave our shop and are powder coated. The company that we send them to is Professional Metal Finishers in Grand Rapids, Michigan.
What Is Powder Coating?
Powder coating is a dry finishing process used on a wide variety of products due to its high quality, durable finish. Powder coating is not only decorative, it also protects the underlying material from the elements. It’s available in an huge range of textures and colors. How does it work? As the Powder Coating Institute describes it:
“Powder coatings are based on polymer resin systems, combined with curatives, pigments, leveling agents, flow modifiers, and other additives. These ingredients are melt mixed, cooled, and ground into a uniform powder similar to baking flour. A process called electrostatic spray deposition (ESD) is typically used to achieve the application of the powder coating to a metal substrate. This application method uses a spray gun, which applies an electrostatic charge to the powder particles, which are then attracted to the grounded part. After application of the powder coating, the parts enter a curing oven where, with the addition of heat, the coating chemically reacts to produce long molecular chains, resulting in high cross-link density. These molecular chains are very resistant to breakdown. This type of application is the most common method of applying powders. Powder coatings can also be applied to non-metallic substrates such as plastics and medium density fiberboard (MDF).”
What Kinds of Items Are Powder Coated?
Professional Metal Finishers does a wide variety of work, some of which you might recognize. Their projects include medical cabinets, car parts, and high-end accessory displays. They do work on automated forklifts that are used by Amazon, Coors, and L’Oreal. Their brake-line display racks are in AutoZone stores. They powder coat Samsung appliance signs that can be seen in stores like Home Depot. They powder coat outdoor utility boxes. They also work locally with Roeda Studio doing memo boards of projects, and they powder coated the signs displayed in the above image.
Since 1986 Professional Metal Finishers has done work across many industries. Much of what they produce are components for larger items, including automotive components for semi-truck engines. They have a very diverse customer base and their goal is “to produce the highest quality finish possible while keeping our prices competitive.”
If you are looking for a company to do powder coating, D+M Metal Products gives Professional Metal Finishers our enthusiastic recommendation for work well done!
