Product Specification

Plastic PPR Pipe Extrusion Making Machine Line

Introduction:

The Plastic PPR Pipe Extrusion Making Machine Line is a high-efficiency, fully automated production line designed for manufacturing Polypropylene Random Copolymer (PPR) pipes, widely used in hot and cold water supply, heating systems, and industrial fluid transportation. This advanced extrusion line ensures precise control over pipe dimensions, superior strength, and smooth surface finish, meeting international quality standards such as ISO, DIN, and ASTM.

The production line includes key components such as:

Extruder – High-output screw design for uniform melting and stable extrusion.

Vacuum Calibration Tank – Ensures precise diameter and roundness.

Cooling System – Multi-stage water cooling for rapid solidification.

Haul-off Unit – Adjustable speed for consistent pulling force.

Cutting Machine – Automatic cutting to desired lengths (4m/6m or custom).

Stacking & Packaging – Automated collection for efficient handling.

Available in different production capacities (e.g., Φ20mm–Φ160mm), the machine supports single or multi-layer PPR pipe extrusion, catering to various market demands.

Material Feeding & Drying

PPR resin pellets are loaded into the hopper and automatically fed into the drying system to remove moisture, ensuring optimal extrusion quality.

Extrusion

The dried material is melted in a single-screw or twin-screw extruder with precise temperature control.

The molten PPR is pushed through a pipe die head to form a continuous pipe shape.

Vacuum Calibration & Cooling

The pipe enters a vacuum calibration tank to stabilize the diameter and wall thickness.

It then passes through a cooling water tank to solidify the structure.

Hauling & Cutting

A haul-off machine pulls the pipe at a controlled speed to maintain uniformity.

An automatic cutting machine cuts the pipe to the required lengths.

Printing & Stacking

A printing machine marks the pipe with specifications (size, pressure rating, brand, etc.).

The finished pipes are collected by an automatic stacking machine for packaging.

Quality Inspection

Each pipe undergoes dimensional checks, pressure testing, and visual inspection to ensure compliance with industry standards.

Features
