U.S. Service Center for High-Performance SPC Extrusion Screws

StarsPlas is strengthening its global supply chain with the establishment of a new StarsPlas Parts Center in the United States, ensuring faster delivery, localized stock, and direct technical support for SPC flooring extrusion manufacturers.

As the core components of any SPC extrusion line, the screw and barrel determine product quality, production stability, efficiency, and long-term operating cost. By expanding our presence in the U.S. market, we aim to help customers improve uptime, reduce maintenance expenses, and secure a more reliable manufacturing process.

High-Precision Screw & Barrel Engineering — Backed by Zhoushan Demaji

To deliver world-class extrusion performance, StarsPlas works closely with Zhoushan Demaji, a globally recognized leader in the production of high-performance twin-screw and single-screw systems. Demaji’s manufacturing excellence, advanced metallurgical expertise, and strict ISO9001:2000 quality control ensure that every screw and barrel meets or exceeds international standards.

Each SPC screw and barrel undergoes a meticulous 1–2 month manufacturing cycle that includes:

• Raw material selection and blanking
• Rough machining and precision CNC finishing
• Quenching, tempering, and specialized heat treatment
• Fine grinding, polishing, and final inspection
• Nitriding or advanced bimetallic alloy coating

This rigorous workflow guarantees dimensional accuracy, stable output performance, and exceptional durability under high-load, continuous-operation conditions.

Advanced Wear-Resistant Coating — The Key to Long Service Life

The lifespan of an extrusion screw is determined primarily by its wear-resistant surface. StarsPlas and Demaji employ advanced alloy coating and powder-metallurgy technologies, including:

• Bimetallic alloy layers (2–5 mm) for extreme abrasion resistance
• Powder metallurgy materials with superior corrosion protection
• ESR-grade hot-work and cold-work tool steels for high-temperature stability
• Customized alloy welding processes for different polymer types

These technologies provide 2–5x longer service life compared with standard nitrided screws and barrels. They are particularly effective for highly filled SPC formulations, PVC compounds, engineering plastics, fluoropolymers, and materials requiring high wear or corrosion resistance.

High Performance Extruder Screws Save Cost Boost Efficiency

What This Means for Our Customers

High-precision screws and barrels directly address several critical industry pain points:

Reduced unplanned downtime

Wear-resistant bimetallic layers maintain stable output and pressure consistency, even under harsh processing conditions, extending maintenance intervals.

Lower long-term operating cost

With longer service life and fewer replacements, manufacturers save significantly on spare parts and production stoppages.

Improved product consistency

Precision machining and stable melt flow ensure uniform thickness, density, and appearance in SPC flooring products.

Higher production efficiency

Optimized screw designs improve plastification, throughput, and energy utilization — essential for high-volume SPC plants.

Faster local service in the United States

The upcoming StarsPlas Parts Center will offer local inventory, emergency replacements, and technical consultation, cutting lead times dramatically for American customers.
