Powerful Mixing and Dispersion Capability
The intermeshing shear (co-rotating/counter-rotating) of twin screws effectively breaks down unmelted particles, glass fiber reinforcements, or pigment agglomerates in injection scraps, ensuring melt uniformity.
Achieves precise dispersion for scraps containing multi-colored blends or additives (e.g., flame retardants, plasticizers), preventing color inconsistencies or performance variations in the final pellets.
Efficient Devolatilization and Venting Design
Multi-stage vacuum venting systems remove volatiles (e.g., residual monomers, decomposition gases) generated during secondary processing, eliminating bubbles or surface defects in pellets.
Ideal for multi-recycled or mildly thermally degraded materials, reducing odors and performance loss in recycled plastics.
Adaptability to Complex Feedstock
Processes irregularly shaped scraps (e.g., sprues, crushed sheets) by optimizing screw configuration and feed zone compression ratios to prevent bridging or uneven feeding.
Handles scraps with trace metal impurities (≤0.1%) through integrated melt filtration for dynamic contamination removal.
Self-Cleaning and Low-Residue Design
Intermeshing screw flights automatically scrape barrel walls, minimizing carbonization residues from high-viscosity or heat-sensitive materials (e.g., PC/ABS blends), extending continuous operation time.
High Efficiency and Increased Throughput
Handles high feed rates (300-2000 kg/h) via forced conveying, ideal for centralized scrap recycling in injection molding facilities, boosting productivity by 40%-60% compared to single-screw systems.
Stable melt flow minimizes strand breakage or die blockage, enabling uninterrupted production.
Energy Savings and Cost Reduction
Precise temperature control (±1°C) and shear heat utilization reduce melting energy consumption (20%-30% lower than single-screw extruders).
Direct scrap recycling cuts raw material waste, lowering overall costs by 15%-25%.
Near-Virgin Quality of Recycled Pellets
Intensive mixing and devolatilization limit mechanical property loss (e.g., tensile/impact strength) to ≤10%, allowing pellets to be reused in injection molding.
Moisture content ≤100 ppm prevents hydrolysis or silver streaks during reprocessing.
Compatibility with Multi-Material Blends
Processes multi-component scraps (e.g., PP/PE, ABS/PC) through zone-specific screw designs, enhancing compatibility and value of recycled materials.
Retains glass fiber length (GF ≤30%) in reinforced scraps, preserving stiffness in recycled products.
Smart Process Control
Integrated PLC/HMI systems monitor real-time parameters (melt pressure, torque, temperature profiles) and auto-adjust settings to compensate for feedstock variations (e.g., viscosity shifts).
Data traceability supports compliance with stringent certifications (e.g., UL, RoHS) for automotive and electronics applications.
High glass-fiber-content scraps: Recycling automotive injection parts while retaining fiber integrity.
Multi-color/multi-material blends: Homogenizing mixed scraps from consumer goods (e.g., appliance housings).
Engineering plastic recovery: Reprocessing high-temperature materials (e.g., PA, PBT) via robust shear and thermal stability.
