In powder/paint spray coating processes, the curing of the coating is an indispensable step. A curing oven refers to a sealed chamber with one or two doors, also known as a drying oven or drying room. Generally, the specific specifications are determined based on the workload of the user and the size of the workpieces. Such small curing ovens usually use electric or gas heating, offering convenient operation, quick temperature rise, and good heat retention.
