1. Yintoni ukuphosa
Isinyithi se-liquid sithululelwa kwi-mold cavity enemilo efanelekileyo inxalenye, kwaye emva kokuba iqiniswe, inxalenye yemveliso enemilo ethile, ubungakanani kunye nomgangatho womphezulu ufunyenwe, obizwa ngokuba yi-casting. Izinto ezintathu eziphambili: i-alloy, imodeli, ukugalelwa kunye nokuqina. Inzuzo enkulu: iindawo ezinzima zingenziwa.
2. Ukuphuhliswa kokuphosa
Imveliso yaqala ngeminyaka yoo-1930 kusetyenziswa oomatshini bomoya kunye neenkqubo zesanti yodongwe eyenziweyo.
Uhlobo lwesanti yesamente lwavela ngowe-1933
Ngo-1944, kwavela iqokobhe lentlabathi yentlabathi eqinileyo egqunywe ngokuqinileyo
Ungundo lwesanti yeglasi eqinileyo yeCO2 yavela ngo-1947
Ngo-1955, kwavela iqokobhe lentlabathi yentlabathi yentlabathi ye-thermal
Ngo-1958, kwavela i-furan resin no-bake sand mold
Ngo-1967, ukungunda kwesanti yokuhamba kwesamente kwavela
Ngo-1968, iglasi yamanzi ene-organic harder yavela
Kwiminyaka engama-50 edlulileyo, iindlela ezintsha zokwenza i-molding molds ngokusebenzisa izinto eziphathekayo, ezifana: ukubumba i-pellet magnetic, i-vacuum yokutywina indlela yokubumba, ukubunjwa kwe-foam elahlekileyo, njl. Okufana nokuphosa i-centrifugal, ukuphosa uxinzelelo oluphezulu, ukuphosa uxinzelelo oluphantsi, ukukhupha ulwelo, njl.
3. Iimpawu zokuphosa
A. Ukuguquguquka okubanzi kunye nokuguquguquka. Zonke iimveliso zezinto zetsimbi. Ukuphosa akukhawulelwanga bubunzima, ubungakanani kunye nokumila kwenxalenye. Ubunzima bunokuba buvela kwiigram ezimbalwa ukuya kumakhulu eetoni, ubukhulu bendonga bunokuvela kwi-0.3mm ukuya kwi-1m, kwaye ukumila kunokuba yinxalenye enzima kakhulu.
B. Uninzi lwemathiriyeli ekrwada kunye neyokuncedisa esetyenziswayo ifumaneka ngokubanzi kwaye inexabiso eliphantsi, njengesinyithi esilahliweyo nesanti.
C. I-Castings inokuphucula ukuchaneka kwe-dimensional kunye nomgangatho we-surface we-castings ngokusebenzisa i-teknoloji ephezulu yokuphosa, ukuze iindawo zinqunywe ngaphantsi kwaye ngaphandle kokusika.
