Lapho izingxenye zokubumba umjovo zicutshungulwa, kuyoba khona ukugcwaliswa okwanele ezimweni eziningi, okuzogcina kuholele kwikhwalithi engafanelekile yemikhiqizo yokubumba umjovo, okuvame ukubangela ukulahlekelwa okuningi kwezomnotho esitshalweni sokubumba umjovo.Ngakho-ke, opharetha bokubumba umjovo badinga ukwazi ukuthi bawenza kanjani umsebenzi omuhle wokugcwalisa.Izixazululo zokunganele.
1. Ukulungiswa okungalungile kokuphakelayo, ukungabi nalutho noma okuningi kakhulu.
Ukulinganisa okuphakelayo okungalungile noma ukusebenza kwesistimu yokulawula okuphakelayo okungalungile, umjikelezo womjovo ongajwayelekile ngenxa yomshini wokubumba umjovo noma isikhunta noma ukulinganiselwa kwesimo sokusebenza, ukucindezela okuphansi kwe-preform emuva noma ukuminyana kwezinhlayiyana eziphansi emgqonyeni kungase kubangele ukushoda kwempahla.Ngezinhlayiya ezinezinhlayiya ezinkulu kanye ne-porosity enkulu, amapulasitiki anesilinganiso esikhulu se-crystallinity ratio, njenge-polyethylene, i-polypropylene, inayiloni, njll., namapulasitiki ane-viscosity ephezulu, njenge-ABS, njll, kufanele enziwe uma izinga lokushisa liphezulu. .Lungisa, lungisa inani lempahla.
Uma kunempahla eningi egcinwe ekugcineni komgqomo, isikulufu sizosebenzisa ingcindezi eyengeziwe yomjovo ngesikhathi senqubo yomjovo ukuze sicindezele futhi sisunduze izinto ezeqile ezigcinwe emgqonyeni, ngaleyo ndlela sinciphise kakhulu ingcindezi yomjovo wepulasitiki esikhunjeni. umgodi.Kunzima ukugcwalisa umkhiqizo.
2. Ingcindezi yomjovo iphansi kakhulu, isikhathi sokujova sifushane, futhi i-plunger noma isikulufu sibuya ngaphambi kwesikhathi kakhulu.
Ipulasitiki encibilikisiwe ine-viscosity ephezulu kanye ne-fluidity encane ekushiseni okuphansi, ngakho-ke ukucindezela okuphezulu kanye nomjovo wejubane eliphezulu kufanele kusetshenziswe.Isibonelo, ekwenziweni kwezingxenye ezinemibala ye-ABS, ukumelana nokushisa okuphezulu kombala kunciphisa izinga lokushisa lokushisa lomgqomo, okufanele linxeshezelwe ngokusebenzisa ukucindezela komjovo ophezulu kanye nesikhathi sokujova eside kunokuvamile.
3. Izinga lokushisa elibonakalayo liphansi kakhulu.
Ukushisa ekugcineni okungemuva komgqomo kuphansi, futhi ukuncibilika okungena emgodini wesikhunta kuphakama ezingeni elinzima ukugeleza ngenxa yomphumela wokupholisa wesikhunta, okuvimbela ukugcwaliswa kwesikhunta se-distal;izinga lokushisa eliphansi kanye ne-viscosity ephezulu ngaphambili komgqomo kunzima ukugeleza futhi kuvimbele isikulufu ukuthi singagelezi.Ukunyakaza okuya phambili, okubangela ukucindezela okuboniswa yigeji yokucindezela ukuba yanele, kodwa ukuncibilika kungena emgodini ngokucindezela okuphansi kanye nesivinini esiphansi.
Lapho izingxenye zokubumba umjovo zingagcwaliswanga kahle, kubaluleke kakhulu ukuthatha izinyathelo ezihambisanayo ngesikhathi.Ukugcwaliswa okunganele kungenye yezinkinga ezivame ukuhlangana nazo ohlelweni lokubumba umjovo.Ngakho-ke, abakhiqizi abakhulu bokubumba umjovo bazoqhuba ukuqeqeshwa kwesikhathi sangempela kwabaqhubi bokubumba umjovo.
