The Vertical Low-Temperature Two-Stage Extruder from JCD Compact Design is a specialized processing equipment engineered for low-temperature extrusion of heat-sensitive materials and space-constrained production workshops. Featuring a unique vertical hybrid structure that integrates a high-speed parallel twin-screw extruder (first stage) and a low-speed single-screw extruder (second stage), it addresses critical industry challenges including thermal degradation of temperature-sensitive plastics, uneven melt quality, and excessive floor space occupation in traditional extrusion lines.

With a production capacity ranging from 100-1500kg/h, this extruder achieves precise low-temperature processing through the single-screw stage’s stable pressure control and closed-loop temperature regulation, while the twin-screw stage ensures efficient plasticization and dispersion. Its vertical compact layout drastically reduces workshop footprint, enabling flexible deployment in small-to-medium production facilities and supporting continuous, stable operation for heat-sensitive material processing, making it an ideal choice for manufacturers prioritizing space efficiency and low-temperature processing precision.

Note: All parameters can be customized based on your heat-sensitive material processing requirements and workshop space constraints.

✅ Precise Low-Temperature Extrusion

• Second Stage (Low-Speed Single Screw): Equipped with a single-head deep groove structure and multi-zone closed-loop heating/cooling system, it maintains ultra-stable extrusion temperature (±1℃), effectively preventing thermal decomposition, discoloration, and performance degradation of heat-sensitive materials (e.g., PLA, PVA, heat-sensitive engineering plastics).
• Mild Shear Force: Low-speed operation generates gentle shear, avoiding excessive mechanical heat buildup and preserving the original physical and chemical properties of raw materials.

✅ Space-Saving Vertical Compact Design

Vertical arrangement of the twin-screw and single-screw units reduces floor space by 40% compared to horizontal two-stage extruders, adapting to narrow production workshops, modular production lines, and small-batch processing scenarios. The compact structure also simplifies pipeline connection and equipment maintenance.

✅ Efficient Plasticization & Stable Melt

• First Stage (High-Speed Twin Screw): Delivers rapid and uniform plasticization of raw materials with strong dispersion performance, ensuring thorough mixing of additives even at low temperatures.
• Balanced Melt Pressure: The single-screw stage stabilizes melt pressure and flow rate, eliminating melt fluctuations and ensuring consistent extrusion quality for continuous production.

✅ Energy-Efficient & Low Maintenance

Optimized power matching for vertical structure reduces energy consumption by 20-30% vs. traditional horizontal models. The simplified vertical layout minimizes wear on transmission components, extending equipment service life and reducing daily maintenance workload.

This extruder is tailored for low-temperature processing and space-limited production scenarios, widely applied to:

• Heat-Sensitive Plastic Processing: PLA biodegradable plastics, PVA water-soluble plastics, heat-sensitive engineering plastics (PC/ABS blends, modified PA), and thermally unstable polymer materials.
• Compact Workshop Production: Small and medium-sized plastic processing enterprises, laboratory-scale production lines, and modular production bases with limited floor space.
• High-Quality Modified Plastics: Low-temperature modified plastics, anti-aging modified materials, and functional composites requiring strict temperature control.
• Continuous Small-Batch Processing: Multi-variety, small-batch production of special plastics, supporting quick material replacement and stable low-temperature operation.
