Double-stage extruder dedicated to PVC cable materials and high-concentration masterbatch

The Functional Masterbatch Production Two-Stage Extruder of JCD Hybrid Series is a professional processing equipment customized for high-loading functional masterbatch production, including color masterbatch, filler masterbatch, conductive masterbatch and anti-static masterbatch. Its unique two-stage hybrid structure combines a high-speed parallel twin-screw extruder (first stage) with a low-speed single-screw extruder (second stage), perfectly solving the industry difficulty points of uneven additive dispersion, unstable masterbatch color, and easy thermal decomposition of functional additives during traditional masterbatch production.

Covering a combined output range of 100-1500kg/h, this extruder utilizes the strong shear force and high dispersion performance of the twin-screw to fully mix and disperse functional additives (pigments, fillers, conductive agents) with base materials, while the low-speed single-screw ensures stable low-temperature extrusion, avoiding the decomposition of heat-sensitive additives and ensuring consistent masterbatch quality. Its compact vertical layout saves workshop space and supports continuous large-scale production, making it the core equipment for functional masterbatch manufacturers pursuing high efficiency and high product quality.

Note: All parameters can be customized according to your functional masterbatch production capacity, additive loading ratio and production line design.

✅ Superior Dispersion for High-Load Masterbatch

• First Stage (High-Speed Twin Screw): Strong shear force and high dispersion performance ensure uniform mixing of high-loading functional additives (up to 80% filler loading) with base materials, avoiding agglomeration of pigments or fillers and ensuring consistent masterbatch performance.
• Second Stage (Low-Speed Single Screw): Stable low-temperature extrusion and precise temperature control prevent thermal decomposition of heat-sensitive additives (e.g., antioxidants, conductive agents), maintaining the original functionality of masterbatches.

✅ Stable Quality & High Consistency

The single-head deep groove structure of the low-speed single-screw stabilizes melt pressure and extrusion speed, ensuring uniform particle size, consistent color and stable physical properties of finished masterbatches, reducing product scrap rate.

✅ Flexible Adaptability

The modular screw design of the twin-screw stage can be flexibly adjusted according to different types of functional masterbatches (color, filler, conductive), adapting to various base materials (PE, PP, ABS, PVC) and additive types.

✅ Space-Saving & Efficient Production

Compact vertical layout reduces floor space by 30% compared to horizontal two-stage extruders, facilitating continuous production line layout; optimized power matching ensures high production efficiency while reducing energy consumption.

This extruder is specially designed for functional masterbatch production scenarios, widely used in:

• Color Masterbatch Production: High-concentration color masterbatch, engineering plastic color masterbatch, and special color masterbatch (matte, glossy, fluorescent) with uniform color dispersion.
• Filler Masterbatch Production: Calcium carbonate, talc powder, kaolin high-loading filler masterbatch, reducing production costs while ensuring product performance.
• Functional Additive Masterbatch Production: Conductive masterbatch, anti-static masterbatch, flame-retardant masterbatch, and antioxidant masterbatch, maintaining the stability of functional additives.
• Special Masterbatch Processing: Nucleating masterbatch, degradation masterbatch, and other special functional masterbatches for automotive, electronics, and packaging industries.
