High-Efficiency PE Extrusion Technology

The production process begins with a high-performance single screw extruder specially designed for processing HDPE, MDPE, and other polyethylene materials.

The optimized screw structure provides:

· Excellent plasticizing performance

· Stable melt pressure

· Uniform material mixing

· High extrusion capacity

· Low energy consumption

· Long service life

The advanced barrel heating system ensures consistent melt temperature throughout production, minimizing material degradation while improving extrusion efficiency.

Advanced Vacuum Extrusion System

Unlike conventional extrusion methods, the vacuum extrusion process produces PE jacket pipes with superior dimensional accuracy and smoother surfaces.

The vacuum calibration system offers several advantages:

· Accurate pipe diameter

· Excellent roundness

· Uniform wall thickness

· Improved concentricity

· Smooth glossy surface

· Reduced material shrinkage

Stable vacuum pressure ensures precise calibration, making the finished jacket pipe ideal for polyurethane foam insulation applications.

Precision Calibration and Cooling

After leaving the extrusion die, the molten PE pipe enters the vacuum sizing tank, followed by multiple stainless steel water cooling tanks.

The optimized cooling system provides:

· Fast and uniform cooling

· Stable pipe dimensions

· Reduced internal stress

· Excellent mechanical strength

· Improved impact resistance

Efficient cooling allows the production line to operate continuously at higher speeds without compromising product quality.

Intelligent Haul-Off and Cutting System

The servo-controlled haul-off machine maintains constant pulling speed throughout the production process.

Features include:

· Stable traction force

· Non-slip rubber belts

· Frequency-controlled motors

· Automatic speed synchronization

· High dimensional accuracy

The automatic planetary cutting machine delivers clean, burr-free pipe ends without deforming the pipe structure.

Optional dust-free cutting technology further improves the production environment.

Fully Automatic PLC Control System

The entire production line is equipped with an advanced PLC control system and user-friendly touchscreen interface.

Operators can easily monitor and adjust:

· Extrusion temperature

· Screw speed

· Vacuum pressure

· Cooling water temperature

· Haul-off speed

· Pipe length

· Alarm system

· Production statistics

The intelligent automation system greatly reduces manual operation while ensuring stable production quality.
