Ngokuhambisana nezidingo ezihlukene zobubanzi bepayipi kanye nokuphumayo, kunezinhlobo ezimbili ze-SJZ80 kanye ne-SJZ65 ekhethekile yama-twin-screw extruder ozikhethela yona; ipayipi elibili lifa lisakaza ngokulinganayo okukhiphayo, futhi isivinini se-extrusion yepayipi ifakwe ngokushesha ipulasitiki. Ibhokisi lokupholisa eline-vacuum elisebenza kahle kakhulu lingalawulwa ngokwehlukana, futhi umsebenzi wokulungisa ulungele inqubo yokukhiqiza. Umshini wokusika ongenathuli, isilawuli esizimele sesiteshi esiphindwe kabili, isivinini esisheshayo, ubude obunembile bokusika. Izinsimbi ezizungezisa umoya ziqeda isidingo sokushintsha izinsimbi. Ngedivayisi ye-chamfering ozikhethela yona.
