Ukugaywa kwesanti yindlela yokuphosa esebenzisa isanti ukuze yenze ngokuqinileyo.Inkqubo yokubunjwa kwesanti yesanti ngokuqhelekileyo iqulunqwe yimodeli (ukwenza i-sand mold), ukwenza i-core (ukwenza undoqo wesanti), ukomisa (ukubunjwa kwesanti eyomileyo), ukubumba (ibhokisi), ukugalela, ukuwa kwesanti, ukucocwa kunye nokuhlolwa kokuphosa.Ngenxa yokuba ukuchithwa kwesanti kulula kwaye kulula, umthombo wezinto eziluhlaza ubanzi, ixabiso lokuphosa liphantsi, kwaye umphumo ukhawuleza, ngoko ke udlala indima ephambili kwimveliso yangoku.I-castings eveliswa yi-akhawunti ye-sand casting malunga ne-90% yomgangatho opheleleyo we-castings.I-Sand casting yenye yezona nkqubo zisetyenziswa kakhulu zendabuko.Ukujulwa kwesanti kwahlulahlulwe ngokokubunjwa kwesanti yodongwe, ukuphosa isanti ebomvu, kunye nokuphosa isanti yefilimu..Ngenxa yokuba izinto zokubumba ezisetyenziselwa ukubunjwa kwesanti zingabizi kwaye kulula ukuzifumana, kwaye zinokusetyenziswa ngokuphindaphindiweyo, ukulungiswa kulula, kwaye ukuveliswa kwesikhunta sesanti kulula kwaye kusebenza kakuhle, kwaye kunokulungelelaniswa kwimveliso yebhetshi kunye nokuveliswa kobuninzi be-castings.Kwangexesha elide, sele iphosa intsimbi, iinkqubo zeSiseko zemveli kwintsimbi, imveliso ye-aluminium.
Ngokutsho kophando, okwangoku kwishishini le-foundry yamazwe ngamazwe, i-65-75% ye-castings iveliswa yi-santi casting, kwaye phakathi kwabo, ukuveliswa kwe-akhawunti yodongwe malunga ne-70%.Esona sizathu sikukuba xa kuthelekiswa nezinye iindlela zokuphosa, ukugalela isanti kuneendleko eziphantsi, inkqubo yokuvelisa ilula, umjikelo omfutshane wemveliso, kunye namagcisa angakumbi abandakanyeka ekugaleleni isanti.Ke ngoko, iinxalenye ze-auto, iindawo zoomatshini, iinxalenye zehardware, iindawo zikaloliwe, njl.Xa uhlobo olumanzi lungakwazi ukuhlangabezana neemfuno, cinga ukusebenzisa isanti yodongwe uhlobo lwesanti eyomileyo okanye ezinye iintlobo zesanti.Ubunzima bokubunjwa kwesanti emanzi yodongwe bungasusela kwiikhilogram ezimbalwa ukuya kwishumi leekhilogram, kwaye ezinye ezincinci kunye neziphakathi ziyaphoswa, ngelixa ukubunjwa okuveliswe ngokubunjwa kwesanti eyomileyo kunobunzima beetoni ezininzi.Zonke iintlobo zokugaywa kwesanti zineengenelo ezizodwa, ke ukuphosa isanti yinkqubo yomfuziselo yeenkampani ezininzi ezisisiseko.Kwiminyaka yakutshanje, abanye abavelisi besanti kwilizwe lam baye badibanisa ukusetyenzwa kwesanti ngokuzenzekelayo, izixhobo zokubumba isanti, kunye nezixhobo zokugalela ezizenzekelayo ukuze kuphunyezwe ukusebenza kakuhle, ixabiso eliphantsi, kunye nomgangatho omkhulu wemveliso esemgangathweni yokwenziwa kwezinto ezahlukeneyo.ukubekwa emgangathweni wamazwe ngamazwe.
