Cold Rolling Twin Screw Extruder Shaft | WR15E WR30 40CrNiMo High Torque Extruder Main Shaft

Our 58MC cold rolling twin screw extruder main shaft is tailor-made for high-end co-rotating twin screw extrusion production lines, designed for high torque, high strength and ultra-precision operation.

We import German pre-hardened alloy steel raw materials and adopt European CNC cold rolling spline forming technology, fully matching 58MC twin screw extruder brick pattern screw assembly. It supports L/D ratios of 40:1, 44:1 and 48:1, with optional built-in internal cooling channels to solve thermal deformation under long-time high-speed heavy-load extrusion.

• WR15E, WR30 and 40CrNiMo imported pre-hardened alloy steel feature outstanding thermal strength, resisting softening and deformation under continuous high-temperature extrusion.
• Excellent thermal shock resistance and anti-fatigue property, effectively avoid spline root fracture under frequent start-stop and alternating torque load.
• Stable internal metal structure, low heat treatment distortion rate, guarantee long-term dimensional consistency.

1. One-step cold rolling forming with European CNC equipment, retains complete metal fiber streamline, no cutting damage to tooth root.
2. Form compressive stress on spline surface, boost torque bearing capacity and extend service life by over 35% compared with traditional milling spline shafts.
3. Ultra-high involute spline dimensional accuracy, zero-clearance fit with screw elements and kneading blocks, prevent material leakage and uneven mixing.
4. Smooth spline surface reduces rotation friction, lower extruder overall energy consumption during continuous production.

This 58MC cold rolling twin screw shaft fits all high-load 58MC co-rotating twin screw extruder production lines:

1. Engineering plastic modification: PA, PC, PBT filled with glass fiber & carbon fiber
2. Color masterbatch, flame retardant masterbatch and functional additive masterbatch manufacturing
3. Biodegradable plastic compounding: PLA, PBAT, starch blending granulation
4. Waste plastic recycling, filled toughened PP/PE extrusion
5. High-temperature high-filler composite material extrusion

1. German imported pre-hardened alloy steel blanks, stable raw material quality without impurity inclusion.
2. Independent cold rolling spline production workshop, full-process CNC precision machining.
3. Complete post-processing procedures: vacuum heat treatment, fine outer circle grinding, optional nitriding wear-resistant treatment.
4. Full inspection before delivery: spline tooth profile, concentricity, straightness and hardness test.
5. Custom service: adjust shaft length, spline modulus, add internal cooling channels according to customer drawing requirements.
