400kg/h Twin Screw PVC Plastic Pellet Extruder Machine

Plastic Pellet Extruder Machine Product Introduction 

The 400kg/h Twin Screw PVC Plastic Pellet Extruder Machine is an industrial extrusion solution for producing high-quality PVC pellets. Capable of handling 400 kilograms per hour, it provides uniform particle size, consistent density, and smooth surface finish.

Equipped with a co-rotating twin screw system, precise multi-zone heating, and a robust feeding mechanism, this extruder is ideal for PVC pipe, sheet, and profile production lines. Its modular design allows easy maintenance, quick die changes, and flexible adjustment for different pellet sizes and formulations. This machine is energy-efficient, stable, and suitable for small to medium-scale PVC manufacturing operations.

Working Principle：

PVC powder or compound is fed into the hopper and transported through the heated barrel by co-rotating twin screws. The material is sheared and melted under heat and pressure, then forced through a die to form uniform pellets. Cooling and cutting systems solidify the pellets to required dimensions. Temperature, screw speed, and feeding rate are precisely controlled for consistent pellet quality.
