High-Performance PP + Glass Fiber Compounding (800 kg/h)

We are pleased to announce the successful delivery of a high-performance twin-screw extrusion line to a major domestic energy and chemical group. This project was specifically engineered to meet the client’s stringent requirements for compounding Polyolefins with Short/Long Glass Fibers, targeting the high-quality Engineering Plastics market.

To address the challenges of glass fiber dispersion and wear resistance, we deployed our U6 Series High-Torque Twin Screw Extruder. With a precise L/D ratio of 44:1 and a 12-barrel configuration, the system ensures optimal melt homogeneity while minimizing fiber degradation.

1. Robust Powertrain

   Powered by a 200kW AC Motor coupled with a genuine German Henschel (TGE65) gearbox, ensuring reliable torque transmission and operational stability.

2. Precision Dosing

   Integrated with 4 sets of Loss-in-Weight Feeders (Kubota/Brabender), providing gravimetric control for resins, powders, and fibers to strictly adhere to formulation standards.

3. Optimized Fiber Feeding

   Features a dedicated Side Feeder (CWJ58) at Barrel 6, designed to introduce glass fibers into the melt gently, preserving fiber length for maximum mechanical strength.

4. Wear Resistance

   Barrels are lined with wear-resistant alloy (45+Cr26MoV), and screw elements are crafted from W6Mo5Cr4V2 tool steel to withstand the abrasive nature of glass fibers.

5. Reliable Pelletizing

   The strand pelletizing system, equipped with a heavy-duty Gantry Pelletizer, delivers a consistent throughput of 700 ~ 800 kg/h.
