Kwiminyaka yakutshanje, ukujulwa kwesanti kusetyenziswe kakhulu kwishishini lokuphosa

Ukugalelwa kwesantiyinkqubo yokugibisela yemveli esetyenziswa ngokubanzi, enokuthi yohlulwe ngokurhabaxa ibe yintlabathi yodongwe, ukugalelwa kwesanti ebomvu, kunye nokuphosa isanti. Ukungunda kwesanti esetyenziswayo ngokuqhelekileyo kuqulunqwe ngundo lwesanti yangaphandle kunye nombindi (umngundo). Ngenxa yeendleko eziphantsi kunye nokufumaneka lula kwezinto zokubumba ezisetyenziswa kwiukugalela isanti, kunye nokukwazi kwabo ukusetyenziswa kwakhona ngamaxesha amaninzi, ukusetyenzwa okulula, kunye nokusebenza ngokukhawuleza kwi-santi casting production, sele beyinkqubo esisiseko yendabuko ekuveliseni isinyithi, isinyithi, kunye ne-aluminium castings, okwenza ukuba zilungele zombini ibhetshi kunye nemveliso enkulu.

Ngokutsho kophando, okwangoku kushishino lwamazwe ngamazwe, i-65-75% ye-castings iveliswa kwaye iphoswe ngokusebenzisa i-sand molds, kunye ne-akhawunti yokuvelisa udongwe malunga ne-70% yale nto. Isizathu esona sizathu kukuba ukuchithwa kwesanti kuneendleko eziphantsi, iinkqubo ezilula zokuvelisa, imijikelezo emfutshane yokuvelisa xa kuthelekiswa nezinye iindlela zokuphosa, kwaye kukho nabasebenzi abaninzi bobugcisa ababandakanyekayo kwisanti. Ke uninzi lwamalungu emoto, iindawo zoomatshini, iinxalenye zehardware, iindawo zikaloliwe, njl. Xa isikhunta esimanzi singenako ukuhlangabezana neemfuno, cinga ukusebenzisa isanti yodongwe izibonda zesanti ezomileyo okanye ezinye iintlobo zokubumba isanti. Ubunzima bezinto ezityhidiweyo eziveliswa yintlabathi eluhlaza yodongwe zinokususela kwiikhilogram ezimbalwa ukuya kumashumi eekhilogram, ziphosa ezinye ezincinci kunye nobukhulu obuphakathi, ngelixa ukubunjwa okuveliswe ngodongwe lwesanti eyomileyo kunobunzima amashumi eetoni. Iindlela ezahlukeneyo zokugalela isanti zineengenelo ezizodwa, ke ukubunjwa kwesanti yinkqubo yokubumba uninzi lwamashishini okuphosa. Kwiminyaka yakutshanje, abanye abavelisi besanti e-China baye badibanisa ukusetyenzwa kwesanti ezenzekelayo, izixhobo zokubumba isanti, kunyeizixhobo zokugalela ezizenzekelayoukufezekisa imveliso esemgangathweni, enexabiso eliphantsi, kunye nomgangatho omkhulu kunye nokusaswa kwezinto ezahlukeneyo. Juneng oomatshini nabo rhoqo esondela emgangathweni ngamazwe.
