Ukucaciswa okuhlukahlukene namamodeli we-PVC twin-screw extruder angakhiqiza amapayipi anobubanzi obuhlukene nobukhulu obuhlukile bodonga. Isakhiwo se-screw esiklanywe ngokukhethekile nge-plasticization efanayo kanye nokukhishwa okuphezulu. Isikhunta se-Extrusion eyenziwe ngensimbi ye-alloy yekhwalithi ephezulu, i-chrome plating yesiteshi sokugeleza kwangaphakathi, ukwelashwa kokupholisha, ukumelana nokuguga nokugqwala; ngomkhono ozinikele wokulinganisa wesivinini esiphezulu, ikhwalithi yendawo yepayipi yinhle. Umsiki okhethekile wepayipi le-PVC wamukela idivayisi ejikelezayo yokugoqa, engadingi ukushintshwa kwesakhiwo ngamadayimitha ahlukene wepayipi. Ngedivayisi ye-chamfering, ukusika, i-chamfering, ukubumba kwesinyathelo esisodwa. Sekela umshini wokubheja we-inthanethi ozikhethela wona.
