Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plastic parts processing equipment, specifically to an oven for plastic spraying. Background Technology
[0002] After plastic spraying, curing treatment is required, and ovens are a common curing equipment. In industrial production, plastic sprayed workpieces can be placed in specially designed ovens, where heating melts and solidifies the plastic particles on the surface, thereby enhancing adhesion and improving surface quality.
