LB-Special-shaped PVC profile production line
For this pvc profile extrusion line, our customers want to produce a special-shaped profile. So we choose SJSZ55/110 22kw extruder. The extruder is controlled by buttons. It has ABB inverter and Schnider electrical contractors. The mould is specially processed in order to keep the profile having good performance. Our calibration table is 8 meters long. All the connection parts for the calibration table is 3mm SUS304. Our haul-offs rubber has special curvatures ensuring the pulling force of the profile. When trial running of this line, our machine extrudes perfect profile.

Conical Twin Screw Extruder
The screws are specifically designed and manufactured for the processing of dry pvc powder blend. Our conical twin screw extruder design cater to the raw materials feature ensuring homogeneous mixture, better plastification and conveying efficiency. The permanent magnet synchronous motor provide high energy efficiency for the extruder. Equipped with PLC control system, it realized controlling the whole production line in the one site.
Mould
Our mould is processed by 40Gr forging and coated hard chromium on surface. The material of whole Vacuum calibrating sleeves is copper
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 PVC profile will be rapidly shaping and cooling. Enough length of the calibration table ensures the shaping of the PVC profile
Haul-off
The force distribution along each caterpillars has sufficient hauling force. We offer good-quality rubber for the haul-off machine. The pneumatic pressure is conducive to the easy adjustment and product protection.
Cutter
It adopts saw cutting method. It is sharp enough to cut the pvc profile without destroying its inner structure.
Finished product
The extruded products has complex structure and smooth surface.
