Industrial powder coating is typically done through a two-step process: first the coating is applied to the part electrostatically and then the newly powdered part is cured under heat to form a hard-plastic coating. This process is very efficient since the powder wraps around the entire part for better coverage and can provide 95% material usage of the powder. There are two different types of powder used for coating parts – Thermoset and Thermoplastic.
Thermoset Powder
This material is used for most of powder coating since it can provide a nice surface layer. The layer not only creates a finished look and provides durability, but it also reacts when baked with other chemical groups in the powder to polymerize harder, which improves the performance properties. After curing thermoset powder, it cannot be melted back into a liquid from further heating.
Thermoplastic Powder
This type does not permanently change during baking and will remelt if heated. These are the type of coatings you may find on refrigerator shelves or metal benches, for example. Thermoplastic powder coatings provide a functional, flexible, and durable coating to a variety of materials.
Wisconsin Oven manufactures industrial powder coating ovens for the finishing industry. These industrial ovens provide uniform air distribution along the entire length of the work chamber resulting in quality cured finishes and optimum cure cycles. Our powder curing ovens are designed to prevent powder blow-off which reduces rework, saving you time and money.
Standard powder coating oven configurations include reach-in, walk-in, and top-load designs that are available in hundreds of sizes. Wisconsin Oven's powder coating ovens are factory adjusted and tested prior to shipment from our facility to help reduce installation and start-up times.
