High Wear-Resistant Nitriding Material Screw Elements for Twin-Screw Extruders with High Precision

Our screw elements are the critical mixing and conveying parts of twin-screw extruders, engineered for high-performance plastic modification, pelletizing, and compounding applications. Built with premium materials and precision machining, they deliver exceptional durability, uniform mixing, and maximum production efficiency for your extrusion lines.

• Superior Material & Extreme Durability: Crafted from high-grade alloys (6542 high-speed steel, Cr12MoV, nitrided steel) with advanced heat treatment, achieving surface hardness of HRC 60+ and offering 3-5 times the wear resistance of standard steel. Resistant to abrasion and corrosion for processing highly abrasive materials.
• Precision Machining for Optimal Mixing Efficiency: CNC-machined to ultra-tight tolerances ensuring minimal clearance between screw elements. Modular "building block" design allows flexible combinations of conveying, shearing, and kneading elements for customized extrusion processes.
• High Productivity & Easy Maintenance: Excellent self-cleaning properties minimize downtime during material changes. Universal compatibility with major twin-screw extruder models (65,75,95,etc. ) for quick installation and seamless integration.
• Kneading Block: KB30°, KB45°, KB60°,KB90°.

• Unmatched Durability: High-hardness alloy with precision heat treatment withstands harsh processing conditions, reducing replacement frequency.
• Uniform Mixing: Tight clearance and modular design eliminate agglomeration, improving product quality and yield.
• Wide Adaptability: Flexible configurations cover diverse applications from masterbatch and modified plastics to polymer blends.
• Maximized Efficiency: Self-cleaning design cuts downtime, ensuring stable, high-output production for greater profitability.

• Plastic modification (glass fiber reinforcement, mineral filling, flame-retardant masterbatches)
• Color masterbatch & functional masterbatch production
• Polymer alloy compounding
• Biodegradable materials & elastomer extrusion
