XPS Foamed Board Production Line CO2 XPS

Technics 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.
