PIPLL PP Screw Barrel | Reliable Solutions for Polypropylene Extrusion

Product Overview

PIPLL’s PP screw barrels are engineered for stable and efficient polypropylene extrusion. With optimized screw geometry, precise temperature control, and reliable melt conveying, PIPLL helps achieve consistent plasticizing, homogeneous melt quality, and stable output across a wide range of PP extrusion applications.

Designed for PP pipe, corrugated pipe, sheet, film, board, rod, and PPH processing, PIPLL screw and barrel solutions support high productivity while maintaining dimensional stability and surface quality.

Core Advantages of PIPLL

· PIPLL Stable Output: Optimized screw geometry supports consistent feeding, melting, and pressure building for stable PP extrusion.

· PIPLL Efficient Plasticizing: Proper compression and mixing design improves melt homogeneity while helping control shear heat and energy consumption.

· PIPLL Wear Resistance: Available in nitrided steel, bimetallic alloys, and wear-resistant surface treatments for standard and filled PP compounds.

· PIPLL Customization: Screw diameter, L/D ratio, compression ratio, mixing section, surface treatment, and barrel configuration can be customized according to your PP material and extrusion line.

PIPLL Technical Highlights

· Materials: Nitrided steel, bimetallic alloys, H13 / SKD61 and customized wear-resistant materials.

· Treatments: Nitriding, bimetallic treatment, hard coating and other wear-resistant surface solutions.

· Design: Optimized feeding, compression, melting, mixing and pressure-building sections for stable PP processing.

PIPLL PP Extrusion Applications

PIPLL screw and barrel solutions are suitable for a wide range of polypropylene extrusion processes, including:

· PP Corrugated Pipe

· PP Pipe

· PP Film & Sheet

· PP Sheet, Panel & Board

· PP Solid Rod & Bar

· PPH Pipe

Why Choose PIPLL?

PP extrusion performance depends on more than screw diameter and L/D ratio. Material grade, melt flow rate, filler content, recycled-material ratio, output requirement, screw speed, and operating temperature can all affect screw and barrel design.

PIPLL evaluates these processing conditions to provide a suitable PP extrusion screw and barrel solution, whether for a new extrusion line or replacement of an existing worn set.

From material selection and screw geometry to machining and surface treatment, PIPLL focuses on stable output, consistent melt quality, wear resistance, and reliable long-term extrusion performance.

Choose PIPLL for customized PP screw barrel solutions built around your actual processing conditions.
