Isitofu sePlastiki sokubumba umgqomo wesikrufu
Uyilo: I-injection screw barrel ngokuqhelekileyo ine-screw kunye ne-cylindrical barrel.I-screw licandelo le-helical-shaped elingena ngaphakathi kwi-barrel.Uyilo lwesikrufu lunokwahluka ngokuxhomekeke kwisicelo esithile kunye nohlobo lweplastiki elungiswayo.
Ukunyibilika kunye nokuxuba: Umsebenzi ophambili we-injection screw barrel kukunyibilika kunye nokuxuba imathiriyeli yeplastiki.Njengoko i-screw ijikeleza ngaphakathi kombhobho, ihambisa iipellets zeplastiki okanye iigranules phambili ngelixa usebenzisa ubushushu kunye nokucheba.Ubushushu obuvela kwizinto zokufudumeza zombhobho kunye nokukhuhlana okwenziwa sisikrufu esijikelezayo kunyibilikisa iplastiki, yenze ubunzima obufanayo obunyibilikisiweyo.
Isitofu: Nje ukuba imathiriyeli yeplastiki inyibilikiswe kwaye yenziwe ibe homogenized, isikrufu siyarhoxa ukuze senze indawo yeplastiki etyhidiweyo.Emva koko, usebenzisa i-injection plunger okanye inkunzi yegusha, iplastiki etyhidiweyo igalelwa kumngundo ngombhobho osekupheleni komphanda.Isantya se-injection kunye noxinzelelo zilawulwa ngononophelo ukuze kuqinisekiswe ukuzaliswa ngokufanelekileyo kwemigodi yokubumba.
Izinto eziphathekayo kunye neeNgqungquthela: Imigqomo ye-screw ye-injection ixhomekeke kubushushu obuphezulu, uxinzelelo, kunye nokunxiba kwe-abrasive ngexesha lenkqubo yokubumba.Ngoko ke, ngokuqhelekileyo zenziwe ngentsimbi ye-alloy high-high-forth ukumelana nale miqathango.Eminye imigqomo inokuthi ibonise i-coatings ekhethekileyo okanye unyango olungaphezulu, olufana ne-nitriding okanye i-bimetallic liners, ukomeleza ukuxhathisa ukunxiba kunye nokwandisa ubomi babo.
Ukupholisa: Ukuthintela ubushushu obugqithisileyo kunye nokugcina amaqondo obushushu obungaguqukiyo, imiphanda ye-injection screw ixhotyiswe ngeenkqubo zokupholisa.Ezi nkqubo, ezifana neebhatyi zokupholisa okanye iziteshi zamanzi, zinceda ukulawula ubushushu bombhobho ngexesha lenkqubo yokubumba inaliti.
I-Screw Design kunye neJiyometri: Uyilo lwesikrufu sokutofa, kubandakanywa ubude baso, i-pitch, kunye nobunzulu betshaneli, inokwahluka ngokusekelwe kwiimfuno ezithile zemathiriyeli yeplastiki eqhutyelwayo.Uyilo olwahlukeneyo lwezikrufu, njengenjongo-jikelele, umqobo, okanye izikrufu zokuxuba, zisetyenziselwa ukunyusela ukunyibilika, ukuxuba, kunye neempawu zenaliti kwiindidi ezahlukeneyo zeeplastiki.
Imigqomo ye-screw yesitofu idlala indima ebalulekileyo kwinkqubo yokubumba, ivumela ukunyibilika okusebenzayo, ukuxuba, kunye nokutofa kwemathiriyeli yeplastiki kwi-mold ukuvelisa uluhlu olubanzi lweemveliso zeplastiki.
