Ukuze ukhiqize isikhunta esinezindonga ezincane kahle, uketshezi lwezinto zokubumba umjovo ezinezindonga ezincane kufanele kube kuhle, futhi kube nesilinganiso esikhulu sokugeleza kuya kobude.Iphinde ibe namandla omthelela omkhulu, izinga lokushisa eliphezulu lokuhlanekezelwa kokushisa, nokuzinza okuhle kohlangothi.Ngaphezu kwalokho, ukumelana nokushisa, ukuncipha komlilo, ukuhlangana kwemishini kanye nekhwalithi yokubukeka kwezinto kufanele kuphenywe.Ake sibheke isisekelo setiyetha sokwakheka kwesikhunta esinezindonga ezincane.
Njengamanje, izinto ezisetshenziswa kabanzi ekubunjweni komjovo zifaka i-polypropylene PP, i-polyethylene PE, i-polycarbonate (i-PC), i-acrylonitrile-butadiene-styrene (ABS) kanye nenhlanganisela ye-PC/ABS.Inqubo yokugcwalisa kanye nenqubo yokupholisa yokubunjwa komjovo ovamile ekubunjweni kuhlanganiswe.Lapho ukuncibilika kwe-polymer kugeleza, ingaphambili elincibilikayo lihlangana nendawo ewumgogodla noma udonga lomgodi onezinga lokushisa eliphansi uma kuqhathaniswa, futhi kuzokwakhiwa ungqimba ngaphezulu. ungqimba lwe-condensation lunomthelela omkhulu ekuhambeni kwe-polymer.
Kudingeka ucwaningo olujulile nolubanzi mayelana nemvelo yongqimba olujiyile ekubunjweni komjovo odongeni oluncane.Ngakho-ke, umsebenzi omningi okudingeka wenziwe ekufanisweni kwezinombolo kokubunjwa komjovo onezindonga ezincane.Iphuzu lokuqala ukwenza ucwaningo olunzulu futhi olubanzi lwethiyori yokubunjwa komjovo odongeni oluncane, ikakhulukazi izakhiwo zesendlalelo se-condensation, ukuze kuphakanyiswe ukuqagela okunengqondo kanye nezimo zemingcele.Kusukela ekuhlaziyweni okungenhla, kungabonakala ukuthi ohlelweni lokubumba umjovo odongeni oluncane, izimo eziningi zihluke kakhulu kulezo zokubumba umjovo ovamile.
Uma kulingisa, ukuqagela okuningi nezimo zomngcele wemodeli yezibalo ze-mellt flow zidinga ukulungiswa kahle ekubunjweni komjovo odongeni oluncane.
