PIPLL PS Screw Barrel | Precision Solutions for Polystyrene Extrusion

Product Overview

PIPLL’s PS screw barrels are engineered for stable and efficient polystyrene extrusion, with controlled melting, uniform mixing, and reliable pressure building. Optimized screw geometry and temperature management help reduce overheating, melt degradation, and surface defects while supporting consistent output and dimensional stability.

Designed for applications including PS sheet, board, plate, profile, pipe, KT foam board, and XPS foam board, PIPLL provides screw and barrel solutions matched to the actual resin grade, foaming system, output target, and extrusion conditions.

Core Advantages of PIPLL

✓ PIPLL Process Stability: Optimized screw geometry supports even melting and stable melt conveying, helping maintain consistent thickness, dimensions, and surface quality.

✓ PIPLL Melt Control: Controlled shear and temperature distribution help reduce thermal degradation, discoloration, and unstable melt behavior during PS processing.

✓ PIPLL Durability: Nitrided steel, bimetallic materials, and wear-resistant surface treatments are available according to production load, additives, and service-life requirements.

✓ PIPLL Customization: Screw diameter, L/D ratio, compression section, mixing design, surface treatment, and barrel configuration can be tailored to the machine and application.

PIPLL Technical Highlights

• Materials: Nitrided steel, bimetallic alloys, H13 / SKD61, and customized wear-resistant material options.

• Treatments: Nitriding, bimetallic treatment, hard coating, chromium plating, and other application-specific surface treatments.

• Design: Controlled compression and shear, uniform melting, stable pressure building, and optimized mixing for PS extrusion.

• Process Matching: Solutions can be adjusted for general-purpose PS, high-impact PS, recycled PS, and foamed PS processing.

PIPLL PS Extrusion Applications

PIPLL screw and barrel solutions can be used across a range of polystyrene extrusion applications, including:

• KT Board (Foam Board)

• PS Pipe

• PS Profile

• PS Sheet / Board / Plate

• XPS Foam Board

For foamed PS applications, screw design must balance melting, mixing, pressure stability, and temperature control to support uniform cell structure and stable extrusion.

Why Choose PIPLL?

PS extrusion performance depends on more than screw diameter and L/D ratio. Resin grade, melt flow rate, recycled content, foaming agent, additives, output requirement, screw speed, and die pressure can all affect screw and barrel performance.

PIPLL evaluates these processing conditions to provide a suitable PS extrusion screw and barrel solution for both new extrusion lines and replacement projects. From screw geometry and material selection to machining accuracy and surface treatment, PIPLL focuses on stable output, consistent melt quality, controlled shear, and reliable long-term operation.

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