High-Filling Plastic Modification Two-Stage Extruder | JCD Series

The High-Filling Plastic Modification Two-Stage Extruder of JCD Series is a professional precision processing equipment engineered for high-proportion inorganic filler plastic modification, a core pain point in the plastic processing industry. Adopting a classic two-stage hybrid structure that combines a high-speed parallel twin-screw extruder (first stage) and a low-speed single-screw extruder (second stage), it perfectly solves the industry challenges of poor filler dispersion, material agglomeration, melt instability and substrate thermal degradation in traditional high-filling modification production.

With a continuous output range of 100-1500kg/h, this extruder relies on the strong shear and high dispersion performance of the twin-screw stage to fully mix and disperse high-ratio inorganic fillers (up to 80% loading) with plastic substrates, while the low-speed single-screw stage achieves stable low-temperature extrusion and melt pressure balance, avoiding filler re-agglomeration and substrate thermal decomposition. As a classic model of JCD Series, it features high adaptability, stable operation and easy adjustment, making it the core production equipment for plastic modification manufacturers engaged in high-filling PE/PP, engineering plastic filling modification and inorganic composite material processing.

Note: All parameters can be customized according to your filler loading ratio, substrate type and high-filling modification production line design requirements.

✅ Superior Dispersion for High-Filling Modification

• First Stage (High-Speed Twin Screw): Reinforced shear and dispersion elements achieve uniform mixing of high-ratio inorganic fillers (calcium carbonate, talc, glass fiber, carbon fiber) with plastic substrates, completely eliminating filler agglomeration and ensuring uniform dispersion at the micro level.
• Modular screw design: Flexible adjustment of screw combination according to different filler types and loading ratios, adapting to both low and high filling modification requirements (30%-80% filler loading).

✅ Low-Temperature Extrusion to Avoid Material Degradation

• Second Stage (Low-Speed Single Screw): Multi-zone closed-loop heating and cooling system realizes precise low-temperature control, avoiding thermal degradation of plastic substrates caused by excessive shear heat in high-filling processing.
• Mild shear environment: Low-speed operation reduces mechanical heat generation, maintaining the original physical and chemical properties of substrates and improving the comprehensive performance of high-filling modified products.

✅ Stable Extrusion & Consistent Product Quality

• Single-head deep groove structure of the single-screw stabilizes melt pressure and extrusion speed, eliminating melt flow fluctuations in high-filling processing and ensuring uniform particle size of finished products.
• Balanced melt homogenization further prevents filler re-agglomeration, ensuring consistent physical properties (tensile strength, impact resistance) of high-filling modified plastics and reducing product scrap rate.

✅ High Adaptability & Efficient Production

• Compatible with various plastic substrates (PE, PP, PVC, ABS, PA, PC) and inorganic fillers (calcium carbonate, talc, glass fiber, mica powder), meeting diverse high-filling modification needs.
• Optimized power matching and vertical compact layout save workshop space while ensuring high production efficiency, supporting 24/7 continuous operation for large-scale high-filling modification production.

  

This extruder is specially customized for high-filling plastic modification scenarios, and is widely used in the production and processing of:
