LB-Double Strand PVC Pipe Extrusion Line

During producing pvc small diameter of the pipe, double strand production line is usually adopted. By this way, the output is largely improved. The double strand keeps perfect balance between wide diameter range capability and productivity.

Line Details

Conical Twin Screw Extruder

Special design for gentle processing of PVC powder

permanent magnet synchronous motor for reducing around 10% energy consumption comparing with DC or AC Motor.

Operator oriented operation logic for clever and easy operation during production

Touch screen (optional) for an integrated information management and easy operation


Specially design for flow channel for superb pipe shaping and reasonable melt pressure.

The large compression ratio ensures the excellent plasticizing effect.

Vacuum Calibration & Cooling 

Separately cooling system for double strand with independent pumps system.

frequency conversion vacuum control system for constant vacuum environment with lowest energy consumption.

Haul-off & cutter combination
