​How to control the color in the injection molding process

In the injection molding process, color control is also a very important thing. If it cannot be effectively controlled, it is easy to cause color mixing and color mismatch, which will affect the effect and progress of injection molding. So, how to do a good job in the color control of injection molding? INVITECH Precision—For more than 30 years, we have been engaged in customized services for precision injection molding, and can customize various precision injection molded products. Next, INVITECH Precision will tell you how to control the color of injection molding.

1. In order to avoid the influence of the injection molding machine and mold components, it is necessary to select an injection molding machine with a suitable capacity for the main product. If you have any questions about the material blind spots in the injection molding machine, you need to replace the equipment. If the chromatic aberration is formed by the casting system and the venting groove of the mold, it can be dealt with by repairing the mold accordingly. Only by correctly handling the problems of injection molding machines and molds, can production be organized and the complexity of the problems can be reduced.

2. To avoid the influence of resin and masterbatch, control of raw materials is the key to thoroughly deal with chromatic aberration. Therefore, especially in the production of light-colored finished products, the impact of different thermal stability of resins on the color fluctuation of finished products cannot be ignored. Production management and raw material inspection are the top priorities.

3. Reduce the influence of barrel temperature on chromatic aberration. In the production process, the color difference caused by the failure of the heating ring is often encountered, or the heating control is out of control.
