37AC 50-400mm PVC Pipe Manufacturing Machine
Complete PVC pipe manufacturing factory solution for producing
pipes ranging from 50mm to 400mm in diameter.
Production Process Flow
The manufacturing process begins with raw material preparation.
Customers can mix PVC powder with additives themselves. The mixture
is fed into the extruder where it is plasticized and extruded into
the mould. The material takes shape in the mould and emerges with
pipe form. The hot, soft pipe is then calibrated and cooled in the
vacuum calibration tank using a vacuum sleeve. Further cooling
occurs in the cooling tank. The haul off unit extracts the pipe
from the extruder, and according to predefined lengths, the pipe is
cut and packaged for transport.

Machine Components
Conical Twin Screw Extruder
Designed for processing sensitive PVC compounds, our conical twin
screw extruders handle materials gently to prevent shearing and
overheating. Capable of processing PVC compounds, PVC-wood
composites, and PP/PE-wood powder mixtures.
Precision Mould
Our specially designed moulds provide ideal material viscosity for
optimal pipe shaping and energy efficiency. All material-contact
surfaces are polished to minimize extrusion friction and ensure
smooth operation.
Vacuum Calibration & Cooling System
Stainless steel vacuum calibration tanks define pipe shape and
surface quality. Adjustable vacuum pressure and high-performance
cooling nozzles ensure precise dimensional control. Sealed gaskets
prevent vacuum leakage, minimizing energy consumption.
Haul Off Unit
Available in crawler track and belt designs for pipes from 16mm to
800mm diameter. Speed synchronization with extrusion ensures
uniform wall thickness. Belt units provide vibration-free operation
for small pipes, while crawler tracks handle larger diameters with
foam PU-coated claws to prevent slipping.
Precision Cutter
High-performance cutting systems with quality encoders ensure
consistent pipe lengths. Available as saw cutter or planetary saw
cutter depending on pipe diameter requirements.
Control System
Comprehensive control system featuring PLC modules, HMI panels,
thermometers, and connectors for stable, precise production control
and monitoring.
Optional Equipment
- Laser marking systems for product identification
- Ink printers for production information marking
- Pipe stackers for automated collection after cutting
- Socket forming machines for creating pipe connections
