Technical Field

[0001] The invention relates to the technical field of curing equipment, in particular to a curing equipment and a curing method for powder coatings. Background Art

[0002] Thermosetting powder coating is a high-performance coating material widely used in various industrial fields. It is mainly composed of resin, curing agent, pigment, filler and additives. This coating will soften after heating, and then evenly adhere to the surface of the object, and then achieve the effect of powder curing by cooling, so that a hard film can be formed on the surface of the object to protect the object. Most of the existing thermosetting powder coating curing equipment uses a heating gun to heat the powder coating on the surface of a single wheel hub to soften it, and then cools it down by natural air drying to achieve the effect of powder curing. However, this method is difficult to heat and soften the powder coating on the surfaces of multiple wheel hubs at one time, thereby reducing the softening efficiency of the powder coating. In order to overcome this problem, a thermosetting powder coating curing equipment that can heat and soften the powder coating on the surfaces of multiple wheel hubs at one time has been developed; The current powder coating curing equipment has a relatively simple structure. Its main function is to heat the coating on the surface of the part to achieve curing. This process requires additional spraying equipment to coat the parts, which makes the overall process complicated.
