WPC production line:
WPC wood plastic door and window production lines use different specifications wood-plastic specialized twin-screw extruder, and wood-plastic specialized single screw extruder, and can be configured to the corresponding vacuum shaping table, hauling machine, horizontal cutting machine, stacker and other auxiliary equipment.
Replacement of mold can produce different specifications of plastic sheet. The tractor uses a unique technology, steady work, good reliability, great traction. Using a vacuum special larger swirl cooling system to increase to facilitate cooling and shapping in order to meet the needs of the production characteristics of wide wood-plastic plate. Transverse cutting device and plate traction speed sync, reasonable design, stable operation it can be automatically cut to length, and equipped with dust recovery.
Main equipments:
1. Parallel twin -screw plastic extruder one set
2. Dead die of Wood plastic composites by user's instruction
3. Mold of vacuum shaping table each specification per set
4. Vacuum cooling shaping table one set
5. Hauling machine(crawler tractor) one set
6. Horizontal cutting machine one set
The WPC profile production line is equipped with conical twin screw extruder, calibration unit, haul off machine, cutting machine
