How to use masterbatch?
The use of color masterbatch is very simple, it only needs to be mixed with resin particles according to the specified ratio and mixed by hand.
In the operation of the equipment should pay attention to the following issues:
The mixing cavity of the injection molding machine or extruder generally has multiple temperature zones, and the temperature near the blanking port should be slightly higher. This is to make the color masterbatch melt quickly after entering the mixing cavity and mix with the plastic resin as soon as possible. , This is conducive to the good dispersion of the masterbatch pigment in the product.
Appropriate back pressure is applied 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.
Properly increasing the die temperature of the extruder can increase the brightness of the product.
