The use of color masterbatch is very simple, just according to the prescribed ratio and resin particles mixing, hand mixing can.
The following issues should be noted in the operation of the device:
1. Injection molding machine or extruder cavity generally have more than one temperature area, the temperature of which near the blanking mouth should be slightly higher, which is to make the color masterbatch into the mixing cavity quickly melting, and the plastic resin as soon as possible mixing evenly, so that the color masterbatch pigment in the products in a good dispersion.
2. The injection molding machine is appropriately applied back pressure, which can improve the mixing effect of the screw, the dispersion of favorable pigments, the side effect of exerting back pressure is to make the injection speed slow.
3. The mould head temperature of the extruder can be improved appropriately, and the brightness of the product is increased.
