Wood Plastic Extrusion Line

Operating Regulations of Wood Plastic Extrusion Line

1. Inspection in front of the wood plastic composite extrusion machine: In order to avoid human negligence causing unstable quality or stoppage in the middle, inspection work must be done and handover records must be made before starting the machine. If you want to check whether the circulating water circuit is unblocked; check whether the refrigeration system can work normally, etc.

2. Install the mold: correctly install the target mold, and adjust the extrusion mold and the shaping mold to the same.

3. Preheating: According to the characteristics of the extruder and wood-plastic raw materials, the barrel and die of the extruder must be heated before production.

4. Startup: After the above inspection and procedures are confirmed to be correct, prepare to start up.

5. Shutdown: When a working period is over or when it needs to be shut down for other reasons, prepare to shut down. Turn off the unloading motor, and put down the cleaning material at the unloading port.

6. Record: At the end of a shift, clean and maintain the machine.

 Wood Plastic Extrusion Line Benefits

Wood plastic extrusion machine line, the use of special design barrel screw and extruder production of wood products. Extruder stand-alone or two-stage mixing directly out, can also be granulated after the second extrusion, saving space, with high yield, extrusion pressure stability, preheating feeder placed at the top of the host, the first out of most wood powder in the residual moisture, so that the host feeding section is more substantial, improve the plasticizing effect and so on. Screw design using a small shear force, not easy to cut wood fiber, can make the material in the barrel to stay within the time evenly. Barrel screw with inlaid alloy and spray wear-resistant corrosion-resistant alloy, greatly extending the service life.

The production line by a series of conical twin screw extruder, vacuum forming machine, traction machine, cutting machine, stacker. It can be used in a variety of plastic products.

Wood Plastic Composite Extrusion Process

WPC means wood plastic composite is a new kind of synthetic material by the process of crushing, milling, mixing, granulating, extruding, calibrating, hauling off and cutting, which uses PVC, PP, PE resin or recycled plastic and plant fiber (wood powder, chaff, straw etc.) as raw material. This kind of wood plastic is not only very similar with natural wood in appearance and feel, but also has the same characteristics with wood of being sawable, planing, drillable. This wood plastic machinery is low bibulous, and is anti-flaming. The proudcts manufactured by wpc extrusion line  are non-toxic, non-pollution, environment-friendly and energy saving, without formaldehyde, benzene,and ammonia and other harmful substances.
