The use of color masterbatch is very simple, just mix with the resin particles according to the specified proportion, and mix by hand.
The following issues should be noted in the operation of the device:
1. The injection molding machine or extruder mixing chamber generally has multiple temperature zones, and the temperature near the blanking port should be slightly higher. This is to make the color master melt rapidly after entering the mixing chamber, with the plastic resin as soon as possible Mix evenly, which is conducive to the masterbatch pigment in the product in a good dispersion.
2. Appropriate application of back pressure to the injection molding machine 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. Appropriately increase the die temperature of the extruder to increase the brightness of the product.
