How to control the color difference of injection molded products (1)

1. Eliminate the influence of injection molding machine and mold factors

To choose an injection molding machine with a capacity equivalent to that of the injection molded product, if the injection molding machine has problems such as material dead ends, it is best to replace the equipment. For the mold casting system, exhaust grooves, etc., which can cause color difference, it can be solved by the maintenance mold of the corresponding part of the mold. The problems of injection molding machines and molds must be solved before the 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 thoroughly solving color differences. Therefore, especially in the production of light-colored products, the obvious influence of the thermal stability of the raw material resin on the color fluctuation of the product cannot be ignored.
