The use of color masterbatch is very simple, just mix it with the resin particles according to the specified ratio, and stir it by hand.

The following issues should be noted in the operation of the equipment:

1、The mixing cavity of injection molding machine or extruder generally has multiple temperature zones, among which the temperature near the blanking port should be slightly higher. This is to make the color masterbatch into the mixing cavity to melt quickly and mix with the plastic resin as soon as possible Uniformity, which is conducive to the good dispersion of the masterbatch pigment in the product.

2、 Appropriate back pressure is applied to the injection molding machine, which can improve the mixing effect of the screw and facilitate the dispersion of the pigment. The side effect of applying back pressure is to slow down the injection speed.

3 、Increasing the temperature of the die of the extruder appropriately can increase the brightness of the product.
