Umshini wokubumba umjovo wesikulufu umphongolo udlala indima ebalulekile enqubweni yokubumba umjovo wezinto ze-PE (polyethylene) kanye ne-PP (polypropylene).Ukusetshenziswa kwayo kulezi zinto ezimbili kubhalwe ngezansi: Ukuncibilika nokuxuba izinto: I-screw barrel idlula ku-screw ejikelezayo nendawo yokushisa ukuze ishise ngokugcwele futhi icindezele izinhlayiya ze-PE noma ze-PP ukuze zincibilike zibe yi-flubleable melt.Ngesikhathi esifanayo, indawo yokuxuba emgqonyeni wesikulufa ingaxuba izinto zezinhlayiya ezihlukene ngokulinganayo ukuze ihlangabezane nezidingo zemikhiqizo ethile.Ingcindezi nomjovo: Ngaphansi kwesenzo somphongolo wesikulufu, into encibilikisiwe ye-PE noma ye-PP ijovwa emgodini wokukhunta ukuze kwakheke umumo womkhiqizo ofunekayo.Ukucindezela kanye nesivinini somjovo we-screw barrel kungalungiswa ngokuya ngezidingo zomkhiqizo ukuze kuqinisekiswe ikhwalithi yemikhiqizo yokubumba umjovo.Ukulawula izinga lokushisa nokupholisa:
I-screw barrel ngokuvamile ifakwe isistimu yokulawula izinga lokushisa ukuze kuqinisekiswe ukuthi into encibilikisiwe ihlala ezingeni lokushisa elifanele.Ngesikhathi esifanayo, ngemva kokuphothula ukubumba komjovo, umkhiqizo udinga ukudlula ohlelweni lokupholisa ukuze uqinise impahla futhi ugcine ukuma kwayo.
Ukulawula nokuqapha inqubo yokubumba umjovo: I-screw barrel ngokuvamile ifakwe uhlelo lokulawula nokuqapha ukuze kuqashwe imingcele efana nezinga lokushisa, ukucindezela kanye nesivinini somjovo futhi uzilungise njengoba kudingeka.Lokhu kunomthelela kwikhwalithi yomkhiqizo engaguquki kanye nokusebenza kahle kokukhiqiza.
Ngamafuphi, i-screw barrel yomshini wokubumba umjovo idlala indima ebalulekile enqubweni yokubumba umjovo wezinto ze-PE ne-PP, iqinisekisa ukuthi izinto zokwakha zincibilika ngokuphelele futhi zixutshwe, nokuthi ukulawulwa kwenqubo yokubumba komjovo kufinyelelwa ukukhiqiza izinga eliphezulu. imikhiqizo yokubumba umjovo.
