Involute Inner Spline Twin Screw Extruder Shaft Adjustable Torque Custom Length

This twin screw shaft matches twin screw extrusion equipment perfectly. Two shafts spin counter-clockwise to build strong shear force for plastic raw materials. The shear action blends different raw materials evenly and keeps stable mixing results every batch.

We forge this shaft with WR15E alloy steel. The raw material delivers strong mechanical strength and anti-rust performance. The solid shaft body holds heavy load during long-hour continuous production. We offer multiple center diameter sizes. You can adjust shaft length and torque bearing capacity based on your production line demands.

1. Precise involute inner spline structure

   The involute spline locks tightly with screw elements. It transfers torque evenly and cuts spline abrasion under frequent heavy rotation.

2. WR15E high-strength alloy steel

   WR15E steel stands high temperature and chemical corrosion. It never bends or cracks under long high-speed compounding work.

3. Fully customizable specs

   We tailor shaft length, center diameter and torque load limit for your extruder. You can choose shafts with or without internal cooling channels.

4. Stable material mixing performance

   Counter-rotating twin shafts create uniform material shearing. This design fits masterbatch, modified plastic and biodegradable plastic granulation.

• Glass fiber reinforced engineering plastic modification
• Color masterbatch, flame retardant masterbatch production
• PLA, PBAT biodegradable plastic blending
• Waste plastic recycling granulation
• High-filler high-temperature composite material processing
