Description

technical field [0001] The invention relates to the field of auto parts production, in particular to a processing technology for auto nylon plastic parts. Background technique [0002] The plastic extrusion molding process in the prior art involves material distribution, stirring, granulation, and molding. Among them, the formula in the batching process selects resin, plasticizer, heat stabilizer, lubricant, filler and other additives. Because the plasticizer is relatively soft, it is easy to affect the banburying of the product during the smelting process. After molding, the continuous volatilization of the plasticizer will accelerate the aging of the product. Even if plastic products adopt secondary processing to improve the surface finish, they can only be painted and polished. Since the main component of varnish is resin and contains extremely volatile thinners, it is easy to fade and fade. The color of the product is monotonous, dull, the cost of secondary processing ...
