The use of the color masterbatch is very simple, it is only necessary to mix with the resin particles according to the prescribed ratio, and it can be mixed by hand. In the operation of the equipment, the following problems should be noted:

The injection molding machine or the extruder mixing chamber generally has multiple temperature zones, and the temperature near the drop opening should be slightly higher, in order to make the color masterbatch into the mixing. After the refining chamber is rapidly melted, it is mixed with the plastic resin as soon as possible, which is beneficial to the dispersion of the color masterbatch in the product.

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 the back pressure is to slow down the injection speed.

Increasing the temperature of the die of the extruder can increase the brightness of the product.
