The PE/PP Profile Extrusion Line is designed for efficient and reliable extrusion of polyethylene (PE) and polypropylene (PP) profiles. It transforms PE/PP raw materials into customized special-shaped profiles ready for decorative and structural uses. With its advanced technology, this line is ideal for production facilities requiring consistent, medium to high-volume output.
Key Features and Benefit
Efficient single-screw extrusion design: Large L/D ratio single-screw (above 33:1) with barrier structure ensures uniform plasticization and stable melt flow for PE/PP, supporting high-speed extrusion and reduced energy consumption.
Precision profile die system: Customized spiral or basket dies paired with vacuum calibration tables achieve accurate complex cross-sections, smooth surfaces, and deformation-free results, suitable for wood-plastic composites or co-extrusion.
Multi-layer co-extrusion and reinforcement options: Enables dual/triple-layer co-extrusion, surface lamination, or fiber reinforcement for enhanced weather resistance, strength, and aesthetic effects.
Vacuum calibration and multi-stage cooling: Multi-segment vacuum tanks with spray/immersion cooling maintain dimensional stability and low internal stress, ideal for large profiles.
These features distinguish the PE/PP profile extrusion line for complex cross-sections and decorative profiles, offering superior weatherability, lightweight strength, and customization while achieving high throughput and low scrap rates.

Primary Applications
Building Decorative Profiles: Prioritized for window/door seals, baseboards, and wall panels, providing weather resistance and aesthetic appeal.
Outdoor Landscaping Materials: For wood-plastic decking, railings, and garden fencing, lightweight and corrosion-resistant for exterior exposure.
Furniture and Interior Decoration: In furniture edging, cabinet profiles, and ceiling trims, easily laminated for wood-grain finishes.
Packaging and Transport Pallets: Producing impact-resistant pallets and frames as wood alternatives for weight reduction.
Industrial Structural Profiles: For corner guards, cable trays, and conveyor guides, offering chemical stability and mechanical strength.
Compared to pipe lines, PE/PP profile lines excel in non-circular sections and decorative applications, serving as eco-friendly alternatives to wood or metal profiles with greater flexibility and environmental durability.
