Cold Rolling Involute Inner Spline Twin Screw Shaft WR15E WR30 40CrNiMoA For Double Co-Rotating Extruder
This involute inner spline shaft matches double co-rotating twin screw extruders. It works as the core carrier for all screw mixing blocks and conveying elements.
We develop this shaft for high-load plastic compounding production. It delivers stable high torque, outstanding structural strength and precise dimensional tolerance for long continuous operation.

- Premium alloy steel raw material
We source pre-hardened alloy steel raw material. The steel keeps stable mechanical strength under long high-temperature extrusion conditions. It resists thermal deformation and chemical corrosion from plastic additives.
- CNC cold rolling spline machining
European imported CNC cold rolling machines finish all involute spline teeth. The spline tooth surface carries torque evenly without local wear. Screw elements lock tightly and never shift during high-speed rotation.
- Vacuum quenching heat treatment
Whole shaft goes through vacuum quenching process. The shaft gains uniform hardness across the whole body. It bears heavy instant torque impact without bending or cracking.
- Fully customizable dimensions
We adjust shaft diameter, total length, L/D ratio and internal cooling structure per your extruder parameters. The brick pattern screw assembly supports flexible layout for mixing, conveying or devolatilization tasks.
Modern twin screw extruders run faster and carry larger torque load. Ordinary shafts deform or wear fast under such harsh working conditions. Our spline shaft solves this point perfectly.
Suitable production fields:
- Engineering plastic modification
- Color masterbatch, filler masterbatch granulation
- Biodegradable plastic extrusion
- Waste plastic recycling compounding
- High-filler composite material processing
- Replacement spare parts for Coperion twin screw extruders
We produce shafts directly in factory. We accept custom drawing processing for non-standard extruder models.
Send your barrel inner diameter, L/D ratio and daily production load to our technical team. We match the proper material and spline size for you and quote fast.
This spline shaft cuts machine failure frequency and extends the whole extruder service cycle.
