Product detail
Conical Twin Screw ExtruderThe screws are specifically designed and manufactured for the processing of WPC powder blend. The permanent magnet synchronous motor has high energy utilization. Equipped with PLC control system on the board, it realized controlling the whole production line in the one site.
Plate Mould
We offer double Strand mould for the WPC profile extrusion line. By this way, the productivity will be highly improved. The optimized channel design ensures high flow performance. The advanced plate mould produced the profile with high precision.
Calibration table
The calibration table has stable steel frame and the whole body material is SUS 304 stainless steel. We have multi-dimension position adjustment system. With precious layout of water pumps and vacuum calibrator, the WPC profile will be rapidly shaping and cooling. Enough length of the calibration table ensures the shaping of the WPC profile
Cutter Unit
We provide saw cutter for the wpc profile production line. With the rotating of the saw, the wpc profile will be cut at the designated length. With the automatic control system on the unit, the whole process is intelligent and easy-operation.
