Pvc Foam Board Production Line

PVC Foam Board Production Line Specifications

The actual production output depends on board thickness, width, formulation, density, production speed and operating conditions. The final machine configuration should be confirmed according to the required product specifications.

SJSZ80/156 PVC Foam Board Production Line

The SJSZ80/156 configuration supports an applicable board width of 1220 mm and a thickness range of approximately 3–25 mm.

Its listed output is 300 kg/h.

This configuration is suitable for manufacturers producing standard-width PVC foam boards within the specified thickness range.

SJSZ80/173 PVC Foam Board Production Line

The SJSZ80/173 configuration supports applicable widths of 1560 mm and 1830 mm and a thickness range of approximately 3–40 mm.

Its listed output is 600 kg/h.

This configuration is suitable for applications requiring wider and thicker PVC foam boards.

PVC Foam Board Production Process

The system integrates material compounding, extrusion forming, calibration, cutting, and recycling into one controlled process.

• Material Compounding Stage
  The mixer prepares PVC resin, CaCO₃, and additives into a uniform formulation.
  This step supports stable feeding conditions for the PVC foam board machine.

• Feeding and Extrusion Stage
  The loader feeds material into a conical twin screw extruder.
  Typical screw diameters are 80/156 mm or 92/188 mm with a 25:1 L/D ratio.

• Plasticizing and Conveying Stage
  The twin screw extruder plasticizes and conveys material under controlled temperature zones.
  Main motor power options include 75 kW and 132 kW depending on output demand.

• Profile Forming Stage
  The extrusion mold shapes the melt into a continuous foam board profile.
  Board thickness can be adjusted from 3 mm to 25 mm during operation.

• Calibration and Cooling Stage
  Calibration and cooling units control board width, thickness, and surface flatness.
  The production width range covers 915 mm to 1830 mm.

• Haul-off Synchronization Stage
  The haul-off unit applies synchronized traction force matched with extrusion speed.
  This ensures stable board movement without deformation.

  

• Cutting and Length Control Stage
  The cutting unit performs programmed length cutting under PLC control.
  Dust collection is integrated during the cutting process.

• Recycling and Reuse Stage
  Edge trim and rejected boards are crushed and ground for reuse.
  Recycled material can be fed back into the PVC foam board machine line.
