Comprehensive Product Line

High-Quality Raw Materials

Providing Customization Services


The barrel is used for twin-screw extruders, twin-screw plastic pelletizers, and twin-screw compounding pelletizers. The plastic pelletizing machine barrel is a crucial component in the plastic pelletizing process, designed to efficiently transform raw plastic materials into uniform pellets suitable for various applications. This barrel, often made from high-quality, heat-resistant materials, plays a pivotal role in the plastic extrusion and pelletizing procedures. The barrel typically consists of several distinct zones, each with specific functions aimed at optimizing the pelletization process. These zones may include the feeding zone, compression zone, melting zone, homogenization zone, and cooling zone.
