1. Kuyini ukulingisa
Insimbi ewuketshezi ithululelwa emgodini wesikhunta ngesimo esifanele ingxenye, futhi ngemva kokuba iqiniswe, kutholakala ingxenye yomkhiqizo onomumo othize, ubukhulu kanye nekhwalithi ephezulu, ebizwa ngokuthi i-casting. Izakhi ezintathu ezinkulu: i-alloy, imodeli, ukuthulula nokuqinisa. Inzuzo enkulu: izingxenye eziyinkimbinkimbi zingakhiwa.
2. Ukuthuthukiswa kokulingisa
Ukukhiqizwa kwaqala ngawo-1930 kusetshenziswa imishini yomoya kanye nezinqubo zesihlabathi sobumba sokwenziwa.
Uhlobo lwesihlabathi sikasimende lwavela ngo-1933
Ngo-1944, kwavela uhlobo lwegobolondo lesihlabathi se-resin coated hard coated
Isikhunta sesihlabathi sengilazi esiqinile se-CO2 savela ngo-1947
Ngo-1955, kwavela uhlobo lwegobolondo le-resin ye-resin sand
Ngo-1958, kwavela isikhunta sesihlabathi se-furan resin no-bake
Ngo-1967, kwavela isikhunta sesihlabathi sokugeleza kukasimende
Ngo-1968, kwavela ingilazi yamanzi ene-organic hardener
Eminyakeni engu-50 edlule, izindlela ezintsha zokwenza isikhunta sokubunjwa ngezindlela ezibonakalayo, njengalezi: ukubunjwa kwe-pellet magnetic, indlela yokufaka uphawu lwe-vacuum, ukubunjwa kwegwebu elilahlekile, njll. Izindlela ezihlukahlukene zokuphonsa ezisekelwe ekubunjweni kwensimbi. Okufana nokusakazwa kwe-centrifugal, ukusakazwa kwengcindezi ephezulu, ukusakaza kwengcindezi ephansi, i-liquid extrusion, njll.
3. Izici zokusakaza
A. Ukuvumelana nezimo okubanzi nokuvumelana nezimo. Yonke imikhiqizo yensimbi. Ukusakaza akunqunyelwe isisindo, usayizi nokuma kwengxenye. Isisindo singasuka kumagremu ambalwa siye emakhulwini amathani, ubukhulu bodonga bungaba kusuka ku-0.3mm kuya ku-1m, futhi ukuma kungaba izingxenye eziyinkimbinkimbi kakhulu.
B. Iningi lezinto ezingavuthiwe neziyisizayo ezisetshenziswayo zitholakala ezindaweni eziningi futhi zishibhile, njengensimbi eyizinsimbi nesihlabathi.
C. Ukusakaza kungathuthukisa ukunemba kwe-dimensional kanye nekhwalithi ephezulu yokulingisa ngobuchwepheshe bokusakaza obuthuthukisiwe, ukuze izingxenye zisikwe kancane futhi ngaphandle kokusikwa.
