When buyers search for “wear-resistant screw barrel”, they are facing a common challenge: standard screws wear out too fast, causing low output, unstable pressure, black spots, and frequent downtime. For factories processing fiberglass, calcium powder, recycled materials, PETG, or abrasive additives, choosing a high-quality wear-resistant screw and barrel is essential.

At Zhoushan Juyuan Machinery Co., Ltd., we specialize in producing premium wear-resistant screw barrels for both extruders and injection molding machines. Using advanced bimetallic alloys and hardfacing technologies, our components deliver 2–5 times longer service life compared with traditional nitrided steel.

Why Choose a Wear-Resistant Screw Barrel?

1. Designed for Abrasive Materials

High-wear materials such as:

• 30–50% fiberglass
• CaCO₃ filled compounds
• Recycled plastics
• PETG / PC / PA
• Wood–plastic composite (WPC)
  require stronger abrasion resistance than standard screws can provide.

A wear-resistant structure significantly reduces erosion, flight deformation, and material leakage.

2. Longer Service Life = Lower Production Cost

A bimetallic screw barrel reduces:

• Maintenance frequency
• Machine downtime
• Replacement expenses

This directly improves factory productivity and profitability.

3. Stable Output and Improved Product Quality

A worn screw causes:

• Unstable melt pressure
• Uneven plasticizing
• Increased scrap rate

Wear-resistant solutions maintain accurate flight geometry for consistent extrusion and molding quality.

Our Wear-Resistant Materials & Technologies

✔ Bimetallic Alloy Barrel Liner

Cast with high-hardness alloy (HRC 62–65), offering exceptional abrasion and corrosion resistance.

✔ PTA Hardfacing on Screw Flights

Plasma welding ensures deep alloy penetration and durable reinforcement on high-wear areas.

✔ High-Performance Tool Steels

Optional materials include:

• SKD61 / H13
• DC53
• W6Mo5Cr4V2

Used for high-temperature and high-shear applications.

✔ Nitriding + Chrome Plating Options

For medium-wear applications, providing a balance between cost and performance.

Applications That Require Wear-Resistant Screws and Barrels

✔ Pipe, profile, and sheet extrusion

✔ Injection molding of engineering plastics

✔ Pelletizing lines for recycled plastics

✔ High-glass-fiber compounding

✔ WPC extrusion

✔ Film blowing with abrasive additives

Wherever wear is a problem, upgrading to a specialized screw barrel is the strongest solution.
