How should injection molding process color control

In the process of injection molding, color control is also a very important thing, if not effectively controlled, it is easy to appear mixed color wrong color, affecting the effect and progress of injection molding processing. So, how can we do a good job of color control in injection molding?

Injection molding processing

1, to eliminate the impact of injection molding machine and mold elements to choose and injection molding main product capacity appropriate injection molding machine, if the injection molding machine has questions such as material dead Angle, the best replacement equipment. On the mold casting system, exhaust groove and other forms of color difference, can be dealt with by the corresponding repair mold of some molds. It is necessary to first deal with the injection molding machine and mold questions to be able to organize production, in order to reduce the complexity of questions.

2, eliminate the influence of material resin, masterbatch control raw materials is the key to thoroughly deal with color difference. Therefore, especially in the production of light color finished products, we can not ignore the thermal stability of materials and resins on the color of the finished products caused by the significant influence. Since most injection molding manufacturers do not themselves produce plastic masterbatch or masterbatch, attention can be focused on production management and raw material inspection

3, reduce the impact of cylinder temperature on the color difference in the production is often encountered because of a heating ring damage failure, or heating control some out of control long burning forming cylinder temperature drastic change and color difference.
