Njengoba sazi, ukulawula izinga lokushisa kuyisihluthulelo esidingekayo kukho konke ukucubungula okushisayo, izinto ze-differnet zidinga ukwelashwa okuhlukile, futhi ngisho nezinto ezifanayo ezinobuningi obuhlukile, nazo zidinga ukuguqulwa ekulungiseni izinga lokushisa.Izinga lokushisa akuwona kuphela ukhiye obalulekile wezinqubo zokushisa, libaluleke kakhulu embonini ye-MIM njengoba lithinta ngokuqondile ukusebenza kokugcina kwemikhiqizo ukuthi ifanelana nemfuneko noma cha.Ngakho-ke ungaqiniseka kanjani ukuthi izinga lokushisa lingalawulwa kahle ngesikhathi sokukhiqiza, lowo mbuzo, i-KELU icabangele ukuxoxa ngayo ngezici ezimbili.
Okokuqala nje, ukufana okungaphakathi kwesithando somlilo ngenkathi i-sintering, ibaluleke kakhulu ekubumbeni umjovo wensimbi (MIM).Ikhwalithi yomkhiqizo kule nqubo, incike ezingxenyeni ezicutshungulwayo zibona izinga lokushisa elifanayo kungakhathaliseki ukuthi zikuphi esithandweni somlilo.Njengoba izithando zomlilo ziba zinkulu, kuba nzima kakhulu ukwazi nokuchaza indawo emnandi ngaphakathi kwesithando somlilo ngoba lapho i-thermocouple ifunda izinga lokushisa elithile, akusho ukuthi isithando somlilo sonke sikulelo qhwa.Lokhu kuyiqiniso ikakhulukazi ngesithando somlilo se-batch esikhulu esishisisa ngomthwalo ogcwele lapho kukhona i-gradient enkulu yokushisa phakathi kwangaphandle komthwalo kanye nendawo yomthwalo.
Izibophezelo kungxenye ye-MIM zikhishwa ngokubamba emazingeni okushisa athile isikhathi esithile.Uma izinga lokushisa elilungile lingafinyelelwa kuwo wonke umthwalo, iphrofayela ingadlulela esigabeni esilandelayo, okuvamise ukuba yirempu.Izibophezelo zizobe zivela engxenyeni phakathi nale rempu.Kuye ngenani le-binder elisele engxenyeni kanye nezinga lokushisa ngesikhathi serempu, ukuhwamuka okungazelelwe kwe-binder kungabangela ukuqhekeka okungamukeleki noma amabhamuza.Kwezinye izimo, ukwakheka kwe-soot kwenzeka, okungabangela ukwakheka kwezinto eziguqukayo.
Ngaphezu kwalokho singakwazi ukulawula izinga lokushisa nge-Nozzle kanye ne-Barrel kusukela kunqubo yokubumba umjovo.Izinga lokushisa lembobo ngokuvamile lingaphansi kancane kunezinga lokushisa eliphezulu lomgqomo, okuwukuvimbela ukwenzeka kwamathe okungenzeka kuphume emlonyeni.Izinga lokushisa le-nozzle akufanele libe phansi kakhulu, ngaphandle kwalokho i-nozzle izovinjelwa ngenxa yokuncibilika kokuqina kokuqala.Kuzophinde kube nomthelela ekusebenzeni komkhiqizo.Izinga lokushisa lomgqomo.Ukushisa komgqomo, umlomo wombhobho kanye nesikhunta kufanele kulawulwe ngesikhathi sokubunjwa komjovo.Amazinga okushisa amabili okuqala athinta ikakhulukazi i-plasticization yensimbi nomsebenzi, kanti owokugcina uthinta ikakhulukazi umsebenzi wensimbi nokupholisa.Insimbi ngayinye inamazinga okushisa asebenzayo ahlukene.Ngisho nensimbi efanayo inamazinga okushisa asebenzayo futhi okwenziwa ahlukene ngenxa yemvelaphi ehlukene noma uphawu.Lokho kungenxa yesilinganiso esihlukene sokusabalalisa isisindo samangqamuzana.Inqubo yokwenza ipulasitiki yensimbi emishinini yokujova ehlukene nayo ihlukile, ukuze izinga lokushisa lomgqomo lihluke.
Akukhathalekile ukuthi hlobo luni lokunganaki kuyiphi inqubo encane, ukwehluleka akunakugwenywa.Ngenhlanhla ithimba lonjiniyela be-KELU linokuhlangenwe nakho okuvelele kanye namasu ngaphezu kweminyaka eyishumi, yenza amakhasimende ethu angabi nakukhathazeka mayelana nekhwalithi yemikhiqizo.Siyakwamukela ukuxoxisana nethimba lethu uma kukhona imibuzo nanoma yimuphi umklamo wangokwezifiso, ithimba lethu lizokusiza ukufeza iphupho lakho.
