| WPC profile production line uses the special designed screw and barrel, die and extrusion process to produce plastic and wood products. the series of products are: one step thick plastic and wood plate extrusion machine, plastic and wood pelletizing machine and different kinds of plastic and wood dies.
This line can adopt one step extrusion method or two-step extrusion method after pelletizing. the two-step extrusion method can save the power and space, and the two-step extrusion method features the machine can gain the high output and stable extrusion pressure. A pre-heating feeder is mounted on the top of the extruder which extracts the humidity from the wood powder, so that the feeding section of the extruder can be filled with enough material and the plasticization effect will be better. Special and well designed screw enables the raw material to be evenly stay in the extruder. The screws and barrel are bi-metallic treated, more wearable and anti-corrosion. |
