Working Principle

Feeding – Raw material mix (powder/pellets + additives) is fed into the hopper.
Plasticizing – The screw conveys, compresses, and melts the material via shear heating.
Metering – Molten PVC is pushed through the die head for shaping.
Cooling & Sizing – The extruded pipe enters vacuum calibration and cooling tanks.
