Industry background and current situation

The processing of color masterbatch has strict requirements for mixing technology and equipment: pigments and additives, basic resin components must be accurately measured, and then evenly dispersed and mixed into the basic resin through mixing systems such as twin-screw extruders and internal mixers.


At present, the production of color masterbatch, pigments and additives, and basic resin components in China are mostly achieved through manual pre mixing processes, which require manual feeding and metering. This process has a low degree of automation, poor accuracy of the formula, and significant environmental pollution. In recent years, the use of weight loss scales and separate addition processes in the production of black and white masterbatch has improved the accuracy and stability of the formula, while reducing environmental pollution.

Premixed

Color-Matching

Different color powders are fed separately using a loss-in-weight feeder, added to an extruder, and plastic is mixed to produce the desired color product. The commonly used matrix resins in this process are PE, PP, PA, and PET.

Premixed

All color powders, additives, and base resin raw materials are premixed in the mixer.
Then, a volumetric feeder is usually added to the twin-screw extruder or internal mixer for processing.
