High-Versatility Two-Stage Pelletizing System for Rigid & Soft Plastics

Product Overview

The Two-Stage Multi-Extrusion System is a high-performance solution designed for manufacturers who require the flexibility to process both rigid plastic regrinds (such as ABS, PC, and rigid PP/PE) and soft plastic scraps (such as PE/PP films and woven bags). By utilizing a “Mother-Daughter” configuration, this system provides the extended processing path necessary to ensure high-purity granulation and superior degassing for diverse material streams.

Core Technical Advantages

• Dual-Stage Material Optimization: The primary “mother” extruder focuses on stable melting and high-intensity degassing, while the secondary “daughter” unit handles final homogenization and high-pressure filtration.
• Advanced Degassing for Soft Plastics: Multiple vacuum degassing ports effectively remove moisture, ink residues, and volatiles commonly found in soft film scraps, ensuring bubble-free pellets.
• High-Torque Performance for Rigid Materials: Equipped with heavy-duty gearboxes and industrial AC motors, the system provides the torque required to process dense, rigid regrinds with ease.
• Sequential Purity Filtration: Independent hydraulic screen changers on both stages provide dual-layer protection, removing contaminants and ensuring a high-grade final resin.
• Precise Thermal Management: Multi-zone heating and cooling systems maintain strict temperature control, preventing material degradation across different polymer types.
• Centralized Automation: A synchronized PLC control system allows operators to manage both extrusion units from a single, user-friendly interface.

Typical Applications

• Soft Materials: Post-consumer and industrial PE/PP films, stretch wraps, and raffia.
• Rigid Materials: Crushed rigid plastics from electronics, automotive parts, and household appliances (ABS, PS, PC, etc.).
• Engineering Plastics: Specialized configurations available for Nylon (PA6/PA66) recycling and modification.
