PVC Single Wall Corrugated Plastic Pipe Extruder Production Machine
Our Single Wall corrugated pipe machine consists of Extruder, Mold Blocks, Corrugated Forming Machine, Cooling Equipment, Counting Machine and Auto winding system. It can continuously produce many kinds of diameter single wall corrugated pipes in high speed.
Key Features
- Series single screw extruder
- Mould for precise pipe shaping
- Vacuum cooling tank for rapid cooling
- Spray cooling tank for larger pipes
- Haul-off machine for continuous production
- Cutting machine for accurate pipe length
- Stacker for organized storage
Production Process
PVC powder + additive → mixing → material feeder → twin screw extruder → mould and calibrator → vacuum and cooling tank → spraying cooling machine → haul-off machine → cutting machine → discharge rack or pipe belling machine.

Production Details
Raw Material Feeding
PVC resin and additives are mixed and fed into the hopper of the extruder.
Melting & Extrusion
The material is heated and melted in the screw extruder (single or twin-screw) to form a homogeneous molten PVC.
Pipe Molding (Corrugation Forming)
The molten PVC is pushed through a die head to form the initial pipe shape. The pipe enters the corrugator mold, where vacuum suction and cooling shape the outer corrugations while maintaining a smooth inner wall.
Cooling & Solidification
The pipe passes through a water cooling tank or spray cooling system to harden the structure.
Traction & Cutting
An automatic haul-off unit pulls the pipe at a controlled speed. A cutting device (saw or guillotine cutter) trims the pipe to the required lengths.
Stacking & Packaging
Finished pipes are collected and packed for storage or shipment.
