Features of Our Super Wear-Resistant Screw Barrels

High Durability and Performance

Our super wear-resistant bimetallic alloy coating screw barrels are manufactured from premium materials such as 38CrMoAlA and treated with advanced nitriding and bimetallic alloy coatings. These processes enhance the hardness and wear resistance of the screw barrels, ensuring they can handle even the most abrasive materials. The plasma nitriding surface hardness ranges from HV 1000-1100, with a nitriding depth of ≥ 0.7 mm, providing excellent durability.

Suitable Applications and Use Cases

Our screw barrels are versatile and suitable for a wide range of applications, including:

• 1. Pipe Extrusion: Ideal for producing PVC, PE, HDPE, and other plastic pipes.
• 2. Sheet Extrusion: Perfect for creating plastic sheets and panels.
• 3. Profile Extrusion: Suitable for various plastic profiles.
• 4. Recycling Extrusion: Efficiently handles recycled materials.
• 5. Compounding Extrusion: Excellent for mixing and compounding different materials.
• 6. Cable/Wire Extrusion: Ensures high-quality cable and wire production.
• 7. Blown Film/Lamination: Ideal for producing high-quality films and laminates.
• 8. Nonwoven Fabric Extrusion: Suitable for nonwoven fabric production.
• 9. Monofilament/Staple Fibre Extrusion: Excellent for producing fibers.
• 10. Cast Film: Perfect for creating cast films.
• 11. Blow Moulding: Ideal for producing hollow plastic parts.
• 12. Injection Moulding: Ensures precise and efficient injection molding processes.

Types of Bimetallic Alloy Screw

• – Type 1: Screw flights welded with bimetallic alloy, commonly used in the manufacturing industry. It is cost-effective and suitable for less problematic plastics.
• – Type 2: Entire screw coated with bimetallic alloy, providing longer working life but at a higher cost.

Types of Bimetallic Alloy Barrels

• – Type 1: Grooved and coated bimetallic alloy barrel. Grooves are drawn in the barrel bore, sprayed with bimetallic alloy compound, and polished smoothly.
• – Type 2: Centrifuge-cast alloy barrel. Uses a centrifugally cast alloy base resistant to wear and corrosion, strengthened with centrifugal casting.
