I. Technical Introduction

First, compounding symmetrically XPS material with other assistant materials like nucleant agent and color batch; Secondly put them into hopper of Grade I extruder by vacuum feeder automatically; Thirdly melting and plasticizing resin by specially designed screw symmetrically, at the same time injecting foam agent  by high pressure and mixing it with melted resin; Fourthly, putting them into Grade II extrusion system to melt, mix, add pressure and cool again and extruding foam board by special mould for board, then cooling and forming board by cooling and forming device；Fifthly, putting the board into Grade I draw-off system and transporting them into Grade  II draw-off system  by transportation  rolls; Sixthly, cutting waste edge  by saw of both-side and finishing transverse cutting according to set length; the last step, stacking and storage.
