Talking about the color control of plastic parts processing1

With the continuous development and advancement of technology, the application of plastics has become more and more extensive. At present, most of the plastic products sold on the market are beautiful in shape and colorful, and all these are formed during the processing of plastic parts. So, how do we control the color of plastic parts when we process plastic parts? 1. Eliminate the influence of injection molding machine and mold factors. It is necessary to choose an injection molding machine with the same capacity as the main injection molding product. If the injection molding machine has problems such as material dead ends, it is best to replace the equipment. For the chromatic aberration caused by the mold gating system, exhaust groove, etc., it can be solved by the maintenance mold of the corresponding part of the mold. The problem of injection molding machine and mold must be solved first before production can be organized to reduce the complexity of the problem. 2. Eliminate the influence of raw resin and color masterbatch. Controlling raw materials is the key to completely solving chromatic aberration. Therefore, especially in the production of light-colored products, the obvious influence of the thermal stability of the raw resin on the color fluctuation of the products cannot be ignored. Given that most injection molding manufacturers do not produce plastic masterbatches or color masterbatches themselves, the focus can therefore be placed on production management and raw material inspection. 3. Reduce the influence of barrel temperature on color difference. In production, it is often encountered that a heating ring is damaged and failed, or the heating control part is out of control and the temperature of the barrel changes drastically, resulting in chromatic aberration.
