To increase the temperature of the whole oven, convection heat is employed, and this heat is then transferred to the product surface by the air. The powder coating is cured from the outside in a curing oven, as the name implies. The exterior curing of powder coatings in curing furnaces slows down the curing process. Infrared ovens, on the other hand, tend to be more expensive, to begin with. To buy best quality industrial curing oven, visit the Eptex Coatings website.
