Powder Coating Oven
Powder coating ovens are equipment used in the final steps of the powder coating process that dry finish finely ground, electrostatically charged particles which have been spray coated onto a product made of metal, plastic, wood or ceramic. This type of coating provides a strong, durable and protective coating to many products for the sports equipment, electronics, agricultural, aerospace, oil and furniture industries. Items like playground equipment, golf clubs, outdoor barbeques, garden equipment and patio furniture are often powder coated and put in powder coating ovens to complete the process. After the product has been coated, it is heated in an infrared or convection oven which melts and fuses the powder unto an even surface coating that can come in virtually any color. Powder coating ovens provide uniform and consistent temperatures, which cause a chemical reaction and cures the coating so that it remains un-scratchable and permanent.
During the heating and curing process, the powder paint on the product is melted inside the oven for two to ten minutes, briefly exposed to UV lights and then cured for a few seconds. This process is not harmful to the environment, produces little waste and is simple to operate. Therefore, operating and maintenance costs are very low. These ovens are able to house items as large as golf carts and swing sets, and are available in three different types-tunnel, box and batch ovens. Tunnel ovens are long, narrow and the products are carried through via a conveyer system in a continuous process. Box and batch ovens are usually square and are loaded by trolleys or jigs. The hot air enters the oven by ducts and louvers from an electrical or gas heat source. Box ovens have a stronger structure and are able to expand and contract based on the size of the product.
