HPL65 Self-Cleaning Co-rotating Twin Screw Compounding Extruder

The HPL65 is engineered for compounders and masterbatch producers who require frequent formula switching with minimal downtime. Featuring a self-wiping screw profile and low-residue geometry, this machine dramatically reduces cleaning time and material waste between production runs.

Core Features

• Self-wiping Screw Profile Design — Precision-engineered intermeshing screw elements with self-wiping geometry ensure thorough material discharge with minimal residue. Reduces cleaning time by up to 70% compared to conventional screw designs, enabling rapid color and material changeover.
• Quick Material Change System — Modular screw and barrel configuration allows complete formula switch within 15-30 minutes. Ideal for short-run production of multiple color masterbatches, functional compounds, and engineering plastics without cross-contamination risk.
• Low Residue Barrel Design — Optimized barrel internal surface with polished finish and streamlined flow channels minimizes material hang-up zones. Integral hard alloy barrel construction with wear-resistant coating ensures long service life even with abrasive formulations.
• Double Side Symmetrical Drive Gearbox — Self-developed symmetrical load-sharing transmission with imported SKF heavy-duty bearings delivers balanced force distribution. Built-in torque overload protection ensures 24-hour stable operation.
• Intelligent PLC Control System — Industrial touch screen with one-click formula storage and recall. Centralized control of feeding, temperature zones, vacuum, and pelletizing with real-time data monitoring and multi-safety alarm.

Key Applications

This machine excels in applications requiring frequent color or material changes: color masterbatch production, additive masterbatch, small-batch engineering plastic compounding, TPE/TPV elastomer compounding, and functional filler masterbatch. The self-cleaning design is particularly valuable for toll compounders serving multiple customers with diverse formulations.

Why Choose HPL65?

With self-cleaning capability, modular flexibility, and robust construction, the HPL65 maximizes production uptime for high-mix low-volume compounding operations. A cost-effective solution for manufacturers seeking to reduce changeover downtime and material waste while maintaining premium compounding quality.
