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, ukusakazwa 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 kuya kumakhulu amathani, ukushuba kodonga kungaba 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.
