Chromatic aberration problem in injection molding process

INVITECH Precision—With more than 30 years of experience in customized processing of precision injection molding parts, we can customize various complex precision plastic injection molding parts according to customer needs. The problem of color difference is one of the common problems in the injection molding process, which is mainly caused by some carelessness in the production. In order to avoid the problem of chromatic aberration in the injection molding process, mainly from the following aspects.

1. In order to remove 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 product. If the injection molding machine has problems such as material dead ends, the equipment needs to be replaced.

2. Remove the influence of raw material resin and masterbatch, and control the raw material is the key to completely solve the color difference.

3. In order to reduce the influence of the barrel temperature on the color difference, due to the damage and failure of the heating ring, the color difference caused by the drastic change of the barrel temperature is often encountered.

4. When the injection molding process parameters need to be adjusted, the injection temperature, back pressure, injection cycle and the amount of masterbatch should not be changed as much as possible. At the same time, observe the effect of changes in process parameters on color. If chromatic aberration is found, it should be adjusted in time.

5. Grasp the influence of barrel temperature and masterbatch dosage on the color change of the product.
