Pigment of use is very simple, just according to the rules of the ratio of mixed with resin particles, mixing by hand. In the operation of the equipment should be paid attention to the following questions:

1. Injection molding machine and extruder mixing cavity generally have multiple temperature zones, including the temperature near the blanking mouth should be slightly higher, this is in order to make the pigment into the mixing chamber after melting quickly, with plastic resin mix as soon as possible, it helps mother color pigment in the products in good dispersion state.

2. Would impose back pressure injection molding machine proper, this can improve the mixing effect of the screw, good pigment dispersion, exert the side effects of back pressure is to make the filling speed is slowing.

3. The extruder die head temperature increasing, the brightness can increase the products.
