WPC board machine from china manufacturer
WPC board machine use fully SIMENS PLC control with fully automatic operation system
WPC board machine use fully SIMENS PLC control with fully automatic operation system
WPC board machine basically includes: double screw extruder(different models will have different capacity), mold, calibration machine(for some certain thickness, no need change mold, but if the range too big, then need change small part on mold), haul off machine(if thickness is too big, then need make haul off machine more bigger), cutting machine(have dust collector device, makes factory clean and protect workers’ health) and automatic plate moving device(reduce required labor, reduce production cost). The capacity ranges from 8 tons – 15 tons per day.
For reducing the cost of WPC board production, we will make the board has co-extrusion process, it means we make the surface materials very good, but make inside materials less good, but product quality still very good, it helps reduce the cost of production PVC WPC crust foam board. Sometimes clients also will coat ASA or Acrylic surface on the top.
