The wood plastic profile bar production line employs the
specially-designed screw barrel, mould, extrusion processing technique
to produce wood plastic products. Either single extruder two-stage
mixing extrusion or two-stage extrusion after granulation can be
adopted. It not only saves both electricity and space, but also has high
productivity and stable extrusion pressure. The preheating charger
mounted on the top of host machine can draw out most of the water from
wood powder firstly, making the charging section of the host machine
more enriched and the plasticization mixing quite excellent. The
optimized screw design reduces the shearing force, unable to cut the
wood fiber and making the stay of materials in barrel even. The screw
barrel, made from duplex metal materials, is wear and corrosion
resistant and has a long service life.
It can produce PVC, PE and PP wood plastic profile bars with a strong material adaptability, mainly applied as trays, package plates, floors, outdoor decorative materials, etc. In addition, the wood powder has a high addition up to 50﹪~75﹪.
