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 the heat of our industrial powder coating ovens to form a hard-plastic coating. This process is 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 is used most often for powder coating since it results in a nice surface layer, creating a finished look and providing durability. It also reacts when baked with other chemical groups in the powder to polymerize harder, which improves the performance properties. After curing thermoset powder in our powder coating ovens, it cannot be melted back into a liquid from further heating.
Unlike thermoset, the thermoplastic powder does not permanently change during baking and will be remelt if heated. These types of coatings can be found on refrigerator shelves or metal benches, for example. Thermoplastic powder coatings provide a functional, flexible, and durable coating for a variety of materials.
Wisconsin Oven manufactures industrial powder coating ovens that are designed to prevent powder blow-off and provide uniform air distribution along the entire length of the work chamber which reduces rework, saving you time and money. This also results in quality cured finishes and optimum cycles. These industrial ovens are factory adjusted and tested prior to shipment from our facility to help reduce installation and start-up times
Our powder-coating oven configurations include reach-in, walk-in, and top-load designs and are available in hundreds of sizes.
