1.Introduction
PP/PE WPC decking extrusion machine cutter used two extruders extrusion directly, also can granulation and then with two-stage approach extrusion, power saving and space efficient, high out put and steady-going extrusion pressure, preheating filling machine fixed on top of main extruder, extract most of water remaining in wood powder to make the feeding stage of extruder more solidify, plasticization and mixing performs very well. Optimized screw design allows a small clearance to make wood fiber not easy to shear and to ensure melting material residence well-distribute. Screw and barrel mad with bimetallic and nitride to ensure wear resistant and corrosion resistance of equipment, so as to prolong service life.
2.Process flow:
a.Material:Wood powder+PP/PE granules+Additives
wood powder+PP/PE+additives→mixer→granulating→extruder→mould→calibrating table→haul-off and cutter unit→stacker→sanding and embossing machine→the final products
b.Material:Wood powder+PVC powder
wood powder+PVC powder+additives→mixer→extruder→mould→calibrating table→haul-off and cutter unit→stacker→sanding and embossing machine→the final products
