The price is primarily driven by the extruder type (Single vs. Conical Twin Screw) and the output capacity (kg/h). For PVC, Conical Twin Screw Extruders are standard due to their superior heat distribution for heat-sensitive PVC powder. Key components affecting value include the PLC control system (e.g., Siemens or Omron), the vacuum calibration tank length (longer tanks allow for higher production speeds), and the haul-off machine type (two-claw, three-claw, or multi-claw depending on pipe diameter).
