Ukubunjwa kwesihlabathi kuyindlela yokulingisa esebenzisa isihlabathi ukuze sakheke siqinile.Inqubo yokubunjwa kwesikhunta sesihlabathi ngokuvamile yakhiwa ukumodela (ukwenza isikhunta sesihlabathi), ukwenza ingqikithi (ukwenza umgogodla wesihlabathi), ukomisa (ukubunjwa kwesikhunta sesihlabathi esomile), ukubumba (ibhokisi), ukuthululwa, ukuwa kwesihlabathi, ukuhlanza nokuhlola ukukhishwa.Ngenxa yokuthi ukukhishwa kwesihlabathi kulula futhi kulula, umthombo wezinto ezingavuthiwe ubanzi, izindleko zokuphonsa ziphansi, futhi umphumela uyashesha, ngakho-ke kusadlala indima enkulu ekukhiqizeni kwamanje kokulingisa.Ama-castings akhiqizwa yi-sand casting account cishe amaphesenti angama-90 wekhwalithi ephelele yokusakazwa.Ukubunjwa kwesihlabathi kungenye yezinqubo zokuphonsa zendabuko ezisetshenziswa kakhulu.Ukubunjwa kwesihlabathi cishe kuhlukaniswe ukubunjwa kwesihlabathi sobumba, ukubunjwa kwesihlabathi esibomvu, nokuphonsa isihlabathi sefilimu..Ngenxa yokuthi izinto zokubumba ezisetshenziswa ekubunjweni kwesihlabathi ishibhile futhi kulula ukuzithola, futhi zingasetshenziswa ngokuphindaphindiwe, ukucubungula kulula, futhi ukukhiqizwa kwesikhunta sesihlabathi kulula futhi kusebenza kahle, futhi kungashintshwa kokubili ukukhiqizwa kwe-batch kanye nokukhiqizwa okukhulu kwe-castings.Sekuyisikhathi eside ikhipha insimbi, izinqubo zendabuko eziyisisekelo ensimbi, ukukhiqizwa kwe-aluminium.
Ngokusho kocwaningo, okwamanje embonini yamazwe ngamazwe yokusungula, i-65-75% ye-castings ikhiqizwa ngokusakazwa kwesihlabathi, futhi phakathi kwabo, ukukhiqizwa kwe-akhawunti yokubunjwa kobumba cishe ku-70%.Isizathu esiyinhloko ukuthi uma kuqhathaniswa nezinye izindlela zokulingisa, ukubunjwa kwesihlabathi kunezindleko eziphansi, inqubo yokukhiqiza elula, umjikelezo wokukhiqiza omfushane, kanye nochwepheshe abengeziwe abenza isihlabathi sokuphonsa.Ngakho-ke, izingxenye zezimoto, izingxenye zemishini, izingxenye ze-hardware, izingxenye zesitimela, njll.Lapho uhlobo olumanzi lungakwazi ukuhlangabezana nezidingo, cabanga ukusebenzisa uhlobo lwesihlabathi esomile sobumba noma ezinye izinhlobo zesihlabathi.Isisindo sokubunjwa sokubunjwa kwesihlabathi esimanzi sobumba singasukela kumakhilogremu ambalwa kuya kumashumi amakhilogremu, kanti ezinye izinsalela ezincane neziphakathi ziyaphonswa, kuyilapho ukubunjwa okukhiqizwe ukubunjwa kwesihlabathi esomile sobumba kungaba nesisindo esingamathani amaningi.Zonke izinhlobo zokubunjwa kwesihlabathi zinezinzuzo ezihlukile, ngakho-ke ukulingisa kwesihlabathi kuyinqubo yokumodela yezinkampani eziningi ezisungulayo.Eminyakeni yamuva, abanye abakhiqizi bokuphonsa isihlabathi ezweni lami bahlanganise ukucutshungulwa kwesihlabathi okuzenzakalelayo, okokusebenza kokubunjwa kwesihlabathi, kanye nemishini yokuphonsa ezenzakalelayo ukuze kuzuzwe ukusebenza kahle okuphezulu, okungabizi kakhulu, kanye nokukalwa okukhulu kokukhiqiza okujwayelekile kokulingisa okuhlukahlukene.ukumiswa kwamazwe ngamazwe.
