Introduction: Cooperating with the Chinese Academy of Sciences in Changchun Institute of Polymer Research and Development, our company successfully researched SJB - Z150 * 30-1220 PE plastic sheet extrusion unit which can manufacture shuttering for building .It is made of PE ,fly ash, calcium carbonate and other fillers which can replace steel templates and  bamboo plastic sheet templates. Its advantages are as follows: low cost, light weight, continuous use 30 -50 times, Waste material can re-use.  SJB - Z150 * 30-1220 PE plastic sheet extrusion unit consists of SJ-150X30 single screw plastic extruder, vacuum automatic feeding machine, dehumidifiers drying hopper, sheets die, 3 roller-ray machine, check-heating devices, cold roll device, cutting edge device, traction, shearing device, roller conveyor device. With the characteristics of compact structure, superior performance, Screw deals with tube optimized design and use of high-performance alloy 38CrMoAiA professional processing which ensure that the plastic unit features homogeneous and stable extrusion, high yield, long life and other advantages. The barrel is made of casting aluminum tube heater heating, cooling wind, precise electronic temperature control instrument. We can adjust the shaping embossing device to make the sheet shaping well. Cutting part adopts fixed length device to ensure the precise length of sheet.
