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

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. The temperature of the section near the blanking port should be slightly higher. This is for the color masterbatch to enter 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 color masterbatch in the product.

2 Appropriately apply back pressure to the injection molding machine, which can improve the mixing effect of the screw and facilitate the dispersion of pigments. The side effect of applying back pressure is to slow down the injection speed.

3 Properly increase the temperature of the die of the extruder to increase the brightness of the product.
