2. In order to improve the above-mentioned defects, the manufacturer will attach the formed elements (such as buckets, washbasins, pots, boxes, plates, boxes, etc.) to the secondary processing (such as screen printing, etc.) after molding. The customer's brand trademark temporarily solves the above-mentioned lack of traditional manufacturing methods. However, the construction site often touches the oil stains, or accidentally slams or scratches when moving, which often causes the color layer of the surface to fade. Or remove it for another big problem.

3.
