Ngokuhambelana neemfuno ezahlukeneyo zobubanzi bombhobho kunye nemveliso, kukho iindidi ezimbini ze-SJZ80 kunye ne-SJZ65 ezikhethekileyo ze-twin-screw extruders ozikhethelayo; umbhobho kabini kufa ngokulinganayo isasaze imveliso eziphathekayo, kunye nesantya umbhobho extrusion ngokukhawuleza plasticized. Ibhokisi yokupholisa i-high-effect double-vacuum ye-vacuum inokulawulwa ngokwahlukileyo, kwaye umsebenzi wokulungelelanisa ulungele inkqubo yokuvelisa. Umatshini wokusika ongenathuli, isikhululo esiphindwe kabini solawulo oluzimeleyo, isantya esikhawulezayo, ubude obuchanekileyo bokusika. Iiclamps ezijikelezayo nge-pneumatic ziphelisa imfuneko yokutshintsha ii-clamps. Ngesixhobo se-chamfering ozikhethelayo.
