wood-plastic extrusion line uses a specially designed screw barrel, mold and extruding machine production of wood-plastic products processing production process. Products include: wood-plastic step plate equipment, wood-step-shaped equipment, wood-step decoration materials and equipment, wood-plastic two-step plate equipment, wood two-step-shaped equipment, wood pelletizing equipment. wood products may be stand-alone direct extrusion extruder can also be extrusion granulation after the two-step method, with energy-saving, space-saving, high output, extrusion stability, and plasticzing effect is good. optimized design smaller screw to shear force, thus easy to cut the wood fiber material can stay in the machine evenly. screw barrel are taking pairs of metal processing, wear corrosion, significantly longer service life.
