Plastic surface treatment such as painting, vacuum plating process will be after the pre-treatment degreasing process to remove the oil on the plastic surface. When painting, the oil will form a weak interfacial layer, resulting in poor adhesion of paint wettability and paint problems, especially in the ABS, PC, or ABS + PC substrate UV vacuum plating process, the oil problem will lead to spraying the bottom UV, vacuum plating surface oil spots, pinholes, craters, and another plating bad phenomenon. The reason is that there is oil on the surface or the oil removal process is not enough or there is residue.
Plastic surface degreasing treatment method
Plastic parts of the source of oil are mainly from the
injection molding stage, the workpiece from the mold off, many times the surface will have some oil stains or visual inspection is not easy to find, but when touched by hand there is a clear sense of oil. The main reason for the formation of oil stains is the use of mold release agent when demolding, followed by the lubricating oil on the guide pillar in order to reduce friction loss, etc., when the
injection molding workpiece is demolded, the residue on the surface of the workpiece, forming the phenomenon of oil stains.
Mold release agent and the lubricant on the guide pillar will cause the subsequent surface painting or UV vacuum plating and other processes to appear bad, so for example, like ABS, PC, or ABS + PC, the application of a lot of substrates on the oil problem how to solve and prevent it? If the root cause of the solution, of course, from the mold to solve but often receive the conditions and technical constraints can not be completed. Then the workpiece has oil stains, you can use the Gui Sheng
plastic injection molding oil treatment agent method, in the workpiece has oil stains, through the priming method sprayed on the surface, forming a transparent film layer, dispersion, and uniformity and cover the oil stains, compared to the vacuum plating industry, the use of white oil immersion and degreasing powder ultrasonic cleaning, more suitable for production and efficiency, and oil removal efficiency is more secure and stable.
