Twin Screw Extruder for Compounding and Pelletizing
Product Description:
A color masterbatch is a concentrated blend of pigments, additives, and thermoplastic resins designed to provide consistent coloration and excellent dispersion in plastic materials. It typically consists of a carrier resin (such as PP, PE, PET, or PVC) combined with pigments and functional additives. This makes it ideal for use in various plastic processing methods.
To produce high-quality color masterbatches, we utilize the ATE Series Co-rotating Parallel Twin Screw Extruder. This advanced extrusion system includes a motor drive, torque distribution gearbox, processing section, temperature control units, die section, and downstream pelletizing systems. The modular design allows for flexible customization based on specific process requirements.

Introduction to ATE Twin Screw Extruder:
The ATE Twin Screw Extruder follows a modular design principle, ensuring stable and reliable performance. Its standardized components allow for easy maintenance and customization according to customer needs. Based on different torque levels, ATE extruders are available in basic and efficiency types.
The process section includes barrels, screw shafts, screw elements, and individual heating/cooling units. Barrels and screw elements are designed using a block structure, which allows for optimal configuration to achieve processes such as conveying, plasticization, compounding, dispersion, homogenization, degassing, and pressure building.
Barrel types vary based on process requirements, including feeding, side feeding, closed, open-top, and vacuum vent barrels. Materials used for barrels can be nitrided steel or bimetallic steel, depending on the application.
Multiple cutting systems can be integrated with the ATE extruder, such as strands pelletizing, hot-face cutting, and underwater pelletizing. The electrical control system supports both instrument and PLC control, with key components sourced from European brands to ensure stability and performance.
