DH2F Double Screw Extruder Transmission Spline Shaft Plastic Extrusion Drive Shaft

DH2F Double Screw Extruder Transmission Spline Shaft | Custom Machining Plastic Extrusion Drive Shaft

DH2F twin screw shaft acts as the core transmission component for double screw plastic extruders. It transfers driving torque to all screw blocks and finishes plastic conveying, melting and mixing during extrusion processing.

We adopt precision machining technology to process every spline shaft. The finished shaft owns stable dimensional accuracy and long service life to support round-the-clock heavy-duty plastic production.

1. Three-tier material selection matches different production budgets

   Customers pick three material grades to fit different production loads and cost plans. Imported alloy steel suits high-temperature, high-filler long-cycle production. WR material balances abrasion resistance and cost for daily compounding. Domestic alloy steel works for low-load general plastic extrusion lines. All raw materials pass strict incoming inspection before processing.

2. High-precision machining stabilizes transmission efficiency

   Advanced CNC machining equipment processes the whole shaft body and spline structure. Uniform spline tooth surface evenly distributes torque during high-speed rotation. No element sliding or eccentric vibration happens under continuous heavy feeding, and the whole extrusion line runs more smoothly.

3. Strong adaptability for all plastic extrusion processes

   This transmission shaft supports melting, dispersion mixing, devolatilization and pelletizing processes. It fits virgin plastic compounding, waste plastic recycling, masterbatch production and modified plastic granulation. The length and diameter accept fully customized processing to match different DH2F extruder barrel L/D ratios.

4. Complete anti-rust packaging avoids transit damage

   We execute standardized multi-layer protection for all finished shafts. We coat anti-rust oil on the whole shaft surface first, then wrap oil-proof paper, bubble cushion and special shaping foam. Final sealed packaging prevents scratches, rust and collision damage during long-distance sea and land transportation.

5. Stable quality control system lowers failure rate

   All semi-finished and finished shafts go through dimensional testing, hardness detection and torsion performance inspection. Every product meets DIN and GB industry standards before delivery. The 6-month warranty covers normal production wear problems to reduce customer after-sales worries.

Plastic extrusion lines need stable transmission shafts to guarantee continuous output. Ordinary shafts wear fast and cause frequent machine shutdowns. DH2F transmission spline shaft cuts maintenance frequency and improves factory production capacity.

Main applicable industries:

• General plastic profile extrusion
• Plastic masterbatch granulation
