WPC board machine from china manufacturer

WPC board machine use fully SIMENS PLC control with fully automatic operation system

Features of WPC board:
1. PVC board has the characteristics of waterproof, flame retardant, acid and alkali resistance, moth proof, light weight, heat preservation, sound insulation and shock absorption.
2. WPC board can be processed the same as wood, and its processing performance is far better than that of wood.
3. WPC board is an ideal substitute for wood, aluminum and composite boards.
4. The surface hardness of PVC skinned foam board is very high, and it is difficult to produce scratches. It is widely used in cabinets, decoration, construction, furniture, etc.

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.

Equipment Features of WPC board machine:

To produce products with different thicknesses, it is only necessary to adjust the mold, and there is no need to replace the mold.
PLC control, high level of automatic calls.
Possess a dust removal device on cutting machine to purify the production space.
use automatic plate moving machine, it reduce the required labor, helps reduce the production cost.
For different thickness, we will suggest clients use different quantities of cooling unit. More thickness, more cooling unit.
Some PVC WPC curst foam board also has embossing texture on the surface, it will requires embossing unit for it. It is also optional for SHARC’s PVC WPC crust foam board production line
SHARC can also supply printing machine(need PVC ink for color, UV varnish for glossy effect, also thinner), lamination machine(PVC film and glue, clients can choose PUR lamination machine or Cold glue lamination machine, PUR lamination machine use PUR hot melt glue, so it is more environmental and healthy) and hot stamping machine(need hot stamping foil and glue) for getting design surface of board.
