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.
