Precision Two-Stage Nylon (PA6/PA66) Pelletizing System

Product Overview

The Two-Stage Nylon Pelletizing System is a specialized industrial solution engineered for the high-performance recycling and modification of engineering plastics. Utilizing a “Mother-Daughter” two-stage configuration, the system provides the extended residence time and precise thermal control necessary to handle the unique viscosity and moisture-sensitivity of Nylon (PA6/PA66). This setup ensures that recycled nylon scrap is transformed into premium-grade resin with physical properties comparable to virgin material.

Core Technical Advantages

• Specialized Two-Stage Synergy: The primary extruder handles initial melting and intensive degassing, while the secondary extruder stabilizes pressure for high-precision filtration and uniform pellet formation.
• Advanced Moisture & Volatile Removal: Features multiple high-vacuum degassing zones across both extrusion stages to effectively eliminate moisture and volatiles, ensuring bubble-free, high-density pellets.
• High-Purity Dual Filtration: Equipped with independent hydraulic screen changers on both the mother and daughter units, providing two layers of protection against contaminants.
• Precise Thermal Management: Multi-zone heating and cooling systems maintain strict temperature profiles to prevent thermal degradation of the nylon polymer chains.
• High-Torque Drive System: Powered by rugged industrial motors and high-torque gearboxes designed for 24/7 continuous operation under demanding loads.
• Intelligent PLC Integration: A centralized control system synchronizes both stages, allowing for real-time monitoring of screw speeds, torque, and melt pressure.

Typical Applications

• Engineering Plastic Recycling: Processing of industrial nylon scraps, including PA6 and PA66 fiber, film, or rigid parts.
• Reinforced Compounding: Ideal for incorporating glass fibers, flame retardants, or impact modifiers into the nylon matrix.
• High-Quality Pelletizing: Producing solid, uniform granules suitable for injection molding or extrusion back into high-value components.
