FAQ

FAQs
  • What makes the SJSZ Series Conical Twin Screw Extruder suitable for PVC pipe extrusion?
    Created with Sketch.
    形状 Created with Sketch.
    The SJSZ Series Conical Twin Screw Extruder is optimized for PVC pipe extrusion with its advanced conical screw design, ensuring superior mixing efficiency and stable output. The vacuum vented system eliminates trapped gases, enhancing material quality for FVC pipe manufacturing and other rigid profiles.
  • How does the conical screw design improve performance compared to parallel twin-screw extruders?
    Created with Sketch.
    形状 Created with Sketch.
    The conical twin screw extruder design increases compression ratio gradually, reducing shear stress and energy consumption. This makes it ideal for heat-sensitive materials like PVC, delivering high-performance extrusion with minimal degradation.
  • What is the maximum production capacity of your industrial plastic extruder?
    Created with Sketch.
    形状 Created with Sketch.
    Depending on the model (e.g., SJSZ-92), the SJSZ Series achieves up to 620 kg/h production capacity, making it a heavy-duty plastic extruder for large-scale operations like sheet, film, and profile manufacturing.
  • Can this extruder handle materials other than FVC and PVC?
    Created with Sketch.
    形状 Created with Sketch.
    Yes, the SJSZ Series supports multiple thermoplastics, including PE, PP, and ABS. Its adjustable screw speed (1-34 rpm) and automated controls ensure compatibility with diverse plastic extrusion applications.
