400 kg/h PVC Pellet Extrusion Machine for Clear Plastic Tubes

PVC Pellet Extrusion Machine Product Introduction 

The 400 kg/h PVC pellet extrusion machine is engineered for high-volume, continuous production of clear PVC plastic tubes with consistent wall thickness and smooth surface finish. It integrates a precision single-screw extruder, high-quality flat die, and water-cooled sizing and calibration system to ensure dimensional accuracy and defect-free output. The PLC-controlled system allows precise adjustment of temperature, screw speed, and extrusion parameters for optimal performance. This extrusion machine is ideal for producing tubes used in construction, electrical wiring, plumbing, industrial fluid lines, irrigation, and other specialized applications requiring high transparency and uniformity.

Working Principle：

The machine melts PVC pellets in the single-screw extruder through friction and heating, forcing the molten PVC through a precision die. The extruded tube is then calibrated and cooled via water baths and sizing rollers. The PLC system monitors temperature, speed, and extrusion pressure to maintain uniform tube dimensions and quality.
