Cold-Forming Screw Shaft

Cold-Forming Involute Spline Shafts for Twin Screw Extruders

High-strength shaft solutions engineered for high torque extrusion and long service life

High-strength shaft solutions engineered for high torque extrusion and long service life

Key Points

  • Enhanced mechanical strength through cold forming technology

  • Superior fatigue resistance for demanding applications

  • Optimized for high torque and high throughput extrusion systems

Cold-Forming shafts are manufactured using advanced Cold-Forming processes to produce involute spline profiles with enhanced mechanical properties.

Unlike conventional machining, Cold-Forming induces plastic deformation of the material, resulting in improved grain structure, higher strength and superior fatigue resistance. This process also ensures excellent dimensional consistency and surface quality of the spline profile.

Cold-Forming involute shafts are specifically designed for high torque twin screw extruders, where reliable load transmission and long service life are critical.




Industries & Applications

  • Engineering Plastics Compounding

    Designed for high torque applications involving engineering polymers and reinforced materials.

  • Masterbatch Production

    Ensures stable operation under high filler loading and demanding mixing conditions.

  • High Throughput Extrusion

    Supports modern extruders operating at high torque density and production capacity.

  • Advanced Compounding Systems

    Preferred in high-performance extrusion lines requiring long-term reliability and precision.
