Complete Production Line Configuration

The complete production system typically includes:

Automatic Vacuum Feeding System

Hopper Dryer

High-Efficiency Single Screw Extruder or Twin Extruders

Co-Extrusion Die Head

High-Speed Vacuum Corrugator

Iron module Blocks

Water Cooling System

Spray Cooling Tank

Haul-Off Machine

Planetary Cutting Machine

Automatic Stacker

PLC Touch Screen Control System

Each component is carefully designed to ensure continuous, reliable, and fully automated production.

Working Principle

Plastic raw materials such as HDPE, PP, or PVC pellets are automatically transported into the extrusion system. Depending on the product structure, one or two extruders melt and plasticize the material separately.

The molten plastic enters a specially designed co-extrusion die head, where the inner smooth layer and outer corrugated layer are formed simultaneously.

The pipe is immediately transferred into the high-speed corrugator equipped with precision Iron mold blocks. Under vacuum forming and synchronized mold movement, the outer corrugated profile is accurately shaped while the inner wall remains smooth.

After passing through the cooling system, the pipe is pulled by the haul-off unit, cut automatically to preset lengths, and transferred to the stacking system for packaging.

The entire manufacturing process is fully automated, ensuring high production efficiency and excellent dimensional accuracy.
