WR15E Involute Spline Extruder Shaft Adjustable Torque Custom Length For Plastic Compounding

WR15E Involute Spline Twin Screw Shaft, Adjustable Torque & Custom Length for Plastic Compounding

This twin screw main shaft matches co-rotating twin screw extruders. A pair of shafts run synchronously to cut and blend plastic raw materials evenly. The involute spline end locks all screw elements tightly without loose shifting during long shifts.

We forge the whole shaft from WR15E alloy steel. The solid one-piece body holds heavy torque load every day. We adjust shaft length, spline size and torque limit to fit your extruder model. We also supply multiple center diameter sizes to meet different output demands.

1. Accurate involute spline connection

   The spline tooth matches kneading blocks and conveying elements perfectly. It transfers torque evenly and cuts long-term wear on connection parts.

2. WR15E alloy steel solid structure

   WR15E steel fights high heat, chemical corrosion and extrusion pressure. The solid shaft never bends under continuous high-speed production.

3. Fully personalized dimension service

   We tailor shaft length, center diameter and torque bearing range. You send your equipment drawing, we machine shafts per your exact specs.

4. Stable dual-shear mixing performance

   Two parallel shafts rotate together to generate balanced shear force. This uniform mixing delivers consistent plastic granulation results batch after batch.

• Modified engineering plastic production
• Color masterbatch, filler masterbatch processing
• Biodegradable plastic granulation (PLA/PBAT)
• Recycled plastic compounding
• High-temperature high-filler composite extrusion

We manufacture twin screw spline shafts direct from factory. We accept small trial orders and bulk OEM orders. Share your extruder model, barrel inner diameter and daily production volume. Our technical team calculates matched shaft specs and sends competitive price within 24 hours. Our heavy-duty spline shaft lowers machine downtime and extends your extruder service life.

Q1: What material do you use for this twin screw shaft?

A1: We adopt WR15E alloy steel for all our main shafts. This material owns high tensile strength and strong anti-corrosion ability.

Q2: What job does the involute spline finish?

A2: The involute spline fastens all screw components. It passes torque steadily and avoids element sliding during operation.

Q3: Can I change shaft length and torque load capacity?

A3: Yes. We adjust shaft length, center diameter and torque limits fully based on your production needs.

Q4: What types of extruders fit this spline shaft?

A4: It fits all co-rotating twin screw compounders for plastic mixing, modification and recycling granulation.

Q5: Why choose solid integrated shaft instead of hollow shaft?

A5: Solid shaft bears bigger extrusion pressure and heavy torque. It resists deformation under long-time heavy load work.
