Kukho iintlobo ezininzi zokuphosa, ezahlulwe ngokwesiko zibe:
① Ukuphoswa kwesanti okuqhelekileyo, kuquka isanti emanzi, isanti eyomileyo kunye nesanti eqinileyo enamakhemikhali.
② Ukuphoswa okukhethekileyo, ngokwezinto zokumodela, kunokwahlulwahlulwa kube kukuphoswa okukhethekileyo ngesanti yeminerali yendalo njengezinto eziphambili zokumodela (ezifana nokuphoswa kotyalo-mali, ukuphoswa kodaka, ukuphoswa kweshell yeworkshop, ukuphoswa koxinzelelo olubi, ukuphoswa okuqinileyo, ukuphoswa kweceramic njl.njl.) kunye nokuphoswa okukhethekileyo ngesinyithi njengezinto eziphambili zokuphoswa (ezifana nokuphoswa kwesinyithi, ukuphoswa koxinzelelo, ukuphoswa okuqhubekayo, ukuphoswa koxinzelelo oluphantsi, ukuphoswa kwe-centrifugal, njl.njl.).
Inkqubo yokuphosa idla ngokuquka:
① Ukulungiswa kwee-cast molds (izikhongozeli ezenza isinyithi esilulwelo sibe yi-solid castings). Ngokwezixhobo ezisetyenzisiweyo, ii-cast molds zinokwahlulwa zibe zii-sand molds, ii-metal molds, ii-ceramic molds, ii-clay molds, ii-graphite molds, njl. Umgangatho wokulungiswa kwe-mold yeyona nto iphambili echaphazela umgangatho we-castings;
② Ukunyibilika nokuthululwa kweentsimbi ezixonxiweyo, iintsimbi ezixonxiweyo (ii-alloys ezixonxiweyo) ziquka ikakhulu isinyithi esixonxiweyo, isinyithi esixonxiweyo kunye nee-alloys ezingezo-ferrous ezixonxiweyo;
③ Unyango kunye nokuhlolwa kokuphosa, unyango lokuphosa luquka ukususa izinto zangaphandle kumbindi kunye nomphezulu wokuphosa, ukususa izinyusi zokuthulula, ukukhulula ukugaywa kwamaqhuqhuva kunye nemithungo kunye nezinye izinto ezibonakala ngathi zincinci, kunye nonyango lobushushu, ukubumba, unyango lokulwa nomhlwa kunye nomatshini wokubumba orhabaxa.
Iingenelo
(1) Ingabumba iintlobo ngeentlobo zeemilo ezintsonkothileyo zezixhobo zokubumba, ezifana nebhokisi, isakhelo, ibhedi, ibhloko yesilinda, njl.njl.
(2) Ubungakanani kunye nomgangatho wee-castings phantse azinamida, zincinci njengeemilimitha ezimbalwa, iigram ezimbalwa, zinkulu njengeemitha ezilishumi, amakhulu eetoni zee-castings zinokuphoswa.
(3) Ingaphosa nayiphi na i-castings yesinyithi kunye ne-alloy.
(4) Izixhobo zokuvelisa i-cast zilula, zityalwa imali encinci, zifakelwa uluhlu olubanzi lwezinto ezikrwada, ngoko ke iindleko zokufaka i-cast ziphantsi.
(5) Ubume kunye nobukhulu bombhobho busondele kwiindawo, ngoko ke umthwalo wokusika uyancipha kwaye izinto ezininzi zesinyithi zinokulondolozwa.
Ngenxa yokuba ukubumba kuneenzuzo ezingentla, kusetyenziswa kakhulu ekuveliseni iindawo zoomatshini ezingenanto.
Inkqubo yokuphosa ingahlulwa ibe ngamacandelo amathathu asisiseko, oko kukuthi ukulungiswa kwesinyithi, ukulungiswa kwesikhunta kunye nokulungiswa kwesinyithi. Isinyithi esityhidiweyo sibhekisa kwizinto zesinyithi ezisetyenziselwa ukuphosa kwimveliso yokuphosa. Yingxubevange eyenziwe yinto yesinyithi njengoko icandelo eliphambili kwaye ezinye izinto zesinyithi okanye ezingezizo zesinyithi zongezwa. Ngokwesiko ibizwa ngokuba yingxubevange yokuphosa, ikakhulu kubandakanya isinyithi esityhidiweyo, isinyithi esityhidiweyo kunye neengxubevange ezingezizo zentsimbi.
