Double Screw Plastic PE Extruder Machine for Pipe Making Machine

APPLICATION:

The Double Screw Plastic PE Extruder Machine for Pipe Making is a high-efficiency extrusion system designed for manufacturing high-quality polyethylene (PE) pipes with consistent wall thickness, superior strength, and smooth surfaces. This machine is widely used in the production of water supply pipes, drainage pipes, irrigation pipes, and other industrial piping systems.

Equipped with a twin-screw extruder, this machine ensures excellent plasticizing performance, high output, and stable extrusion. The advanced heating and cooling systems maintain optimal processing temperatures, while the precision gearbox and screw design enhance durability and energy efficiency.

PE PIPE PRODUCTION SPECIFICATIONS:

Production Process of Double Screw PE Pipe Extruder Machine

Plastic extruder → mould → forming machine →pull off machine → cutter / winder

Material Feeding

PE raw material (in pellet or powder form) is fed into the hopper.

An automatic feeding system ensures a consistent material supply.

Material Feeding & Drying

HDPE/LLDPE resin pellets are loaded into the hopper of the extruder.

Optional drying system removes moisture to ensure material quality.

Extrusion Melting & Plasticizing

The material enters the screw barrel, where it is heated, melted, and homogenized by the rotating screw.

Temperature zones are precisely controlled for optimal melting (typically 150°C–220°C for PE).

Pipe Die Head (Moulding)

The molten plastic is forced through a pipe die head, shaping it into a continuous pipe with the desired diameter and wall thickness.

Vacuum Calibration (Sizing)

The hot pipe enters a vacuum calibration tank where it is cooled and precisely sized using vacuum pressure.

Cooling System

The pipe passes through a water cooling tank (spray or immersion type) to solidify its structure.

Haul-off (Pulling) Unit

A crawler track haul-off or belt puller grips the pipe, ensuring consistent speed and tension for uniform wall thickness.

Cutting & Stacking

An automatic cutting machine (saw or guillotine) cuts the pipe to the required length.

Finished pipes are stacked or coiled (for flexible pipes) for storage.

Printing & Marking (Optional)

A printing machine applies product info (size, standards, manufacturer details) if required.

Quality Inspection

Pipes are checked for dimensions, ovality, pressure resistance, and surface smoothness.

Packaging & Storage

Pipes are bundled or packed for shipment.
