Plastic Extruder PE Pipe Extrusion Production Line Co-Extrusion
Machine
APPLICATION:
Our PE Pipe Extrusion Production Line with Co-Extrusion Machine is
a high-performance, automated system designed for manufacturing
high-quality polyethylene (PE) pipes with single or multi-layer
structures. This advanced production line ensures excellent pipe
strength, durability, and precision, making it ideal for water
supply, gas distribution, industrial pipelines, and drainage
systems.
The co-extrusion capability allows for the production of
multi-layer pipes with enhanced properties, such as improved UV
resistance, oxygen barrier, and mechanical strength. The system is
energy-efficient, user-friendly, and complies with international
standards (ISO, DIN, ASTM).

Material Feeding & Drying
PE resin (HDPE/MDPE/LDPE) is fed into the hopper, optionally dried
to remove moisture.
For co-extrusion, multiple material feeders supply different layers
(e.g., inner/outer layers + adhesive).
Melting & Extrusion
The main extruder melts and homogenizes the PE material.
In co-extrusion, auxiliary extruders process additional layers
(e.g., barrier or colored layers).
Pipe Head & Die Forming
Molten plastic passes through a multi-layer die head, forming a
seamless pipe structure.
Die design ensures uniform wall thickness and smooth surfaces.
Vacuum Sizing & Cooling
The pipe enters a vacuum calibration tank to set the exact
diameter.
Subsequent water cooling tanks solidify the pipe while maintaining
dimensional stability.
Pulling & Cutting
A haul-off unit pulls the pipe at a controlled speed.
An automatic cutter trims pipes to the required length (e.g., 6m,
12m, or custom sizes).
Stacking & Packaging
Finished pipes are collected by a stacking machine or conveyor.
Optionally printed, labeled, or bundled for shipment.
