Kunezinhlobo eziningi zokulingisa, ezihlukaniswa ngokwesiko zibe:
① Ukubunjwa kwesihlabathi okujwayelekile, okuhlanganisa isihlabathi esimanzi, isihlabathi esomile nesihlabathi esiqiniswe ngamakhemikhali.
② Ukukhishwa okukhethekile, ngokusho kwezinto zokumodela, kungahlukaniswa ngokusakazwa okukhethekile ngesihlabathi samaminerali emvelo njengento eyinhloko yokufanisa (njengokutshala izimali, ukuphonsa udaka, ukukhishwa kwegobolondo le-workshop, ukukhishwa kwengcindezi engemihle, ukuphonsa okuqinile, ukuphonsa kwe-ceramic njll.) kanye nokusakazwa okukhethekile ngensimbi njengento eyinhloko yokuphonsa (njengokubunjwa kwensimbi, ukuphonswa kwengcindezi, ukucindezela okuphansi, ukucindezela okuphansi njll.)
Inqubo yokulingisa ngokuvamile ihlanganisa:
① Ukulungiswa kokubunjwa kokubunjwa (iziqukathi ezenza insimbi ewuketshezi ibe ukubunjwa okuqinile). Ngokwezinto ezisetshenziswayo, ukubunjwa kwe-casting kungahlukaniswa zibe isikhunta sesihlabathi, isikhunta sensimbi, isikhunta se-ceramic, isikhunta sobumba, isikhunta se-graphite, njll.
② Ukuncibilika nokuthululwa kwezinsimbi ezisansimbi, izinsimbi ezisansimbi (ama-alloys) ikakhulukazi zihlanganisa insimbi ecijile, insimbi ekhonjiwe kanye nama-alloys angeyona ayoni;
③ Ukwelashwa nokuhlolwa kokulingisa, ukwelapha ngokuphonsa kuhlanganisa ukususwa kwento yangaphandle endaweni ewumongo kanye nendawo yokuphonsa, ukususwa kwezikhuphukeli ezithelayo, ukugaywa kwama-burrs nama-seams nokunye okuqhamukayo, kanye nokwelashwa kokushisa, ukubumba, ukwelashwa okunqanda ukugqwala kanye nokugaya kanzima.
Izinzuzo
(1) Ingasakaza izinhlobonhlobo zezimo eziyinkimbinkimbi zokulingisa, njengebhokisi, uhlaka, umbhede, isilinda block, njll.
(2) Ubukhulu nekhwalithi yokulingisa cishe akunqunyelwe, kuncane njengamamilimitha ambalwa, amagremu ambalwa, amakhulu amamitha ayishumi, amakhulu amathani okulingisa angaphonswa.
(3) Ingaphonsa noma iyiphi insimbi ne-alloy castings.
(4) Imishini yokukhiqiza eyi-casting ilula, i-investment encane, isakazwa ngezinhlobonhlobo zezinto ezingavuthiwe, ngakho-ke izindleko zokulingisa ziphansi.
(5) Ukuma nobukhulu bokubunjwa kuseduze nezingxenye, ngakho-ke umthwalo wokusika uyancipha futhi izinto eziningi zensimbi zingasindiswa.
Ngenxa yokuthi ukulingisa kunezinzuzo ezingenhla, kusetshenziswa kakhulu ekukhiqizeni okungenalutho kwezingxenye zemishini.
Inqubo yokuphonsa ingahlukaniswa ibe izingxenye ezintathu eziyisisekelo, okungukuthi ukulungiswa kwensimbi, ukulungiswa kwesikhunta kanye nokucubungula ukuphonsa. I-Cast metal isho into yensimbi esetshenziselwa ukusakaza ekukhiqizeni ukusakaza. I-alloy eyakhiwe isici sensimbi njengoba ingxenye eyinhloko nezinye izinsimbi noma izakhi ezingezona ezensimbi zengezwa. Ijwayele ukubizwa nge-casting alloy, ikakhulukazi okuhlanganisa insimbi ecijile, i-Cast steel nama-alloys angeyona ayoni.
