I roto i te nuinga o te wā, kei te whakamahia ngā momo rerekē o te makanga ki te whakaputa i castings whakarewa. Ko te kupu, He maha ngā painga makanga turai :. No feāvaaki tuwhera, me inclusions para i roto i te hua maka, rauemi nui-kiato, nui haere ātete whakarewa kākahu, tutuki nei i te hanganga kākahu, etc. huaina te painga matua o tenei tikanga e rauemi penapena i runga i te workpiece me te whakaiti nui i roto i te matatini o te tukanga katoa tukanga (e tika ana ki te āwhiwhitanga maximal e maka ki te hua oti).

he maha o "tango" makanga turai kua. Ko ētahi o ēnei: whiwhi hē papa noa o te workpiece, ki te hehema wā puka rauemi wehenga utu nui (e tika ana ki te nui haere ngā whakaritenga o te tika ahu).

E whakamahia mihini Special i roto i te tikanga makanga turai. rerekē ratou i roto i te ahunga o te tuaka o te hurihanga - poutū, tuaka whakapae, me te hinaaro (te pono, kei te uaua whakamahia te mua). Mihini ki tuaka poutū whakamahia ki te whakaputa i billets-roa iti ki ngā rerekētanga iti o takahanga (mowhiti, piston, ringaringa me te rite). Mihini ki te tuaka whakapae o te hurihanga tukua ki te whiwhi roa-roa castings tiketike-pū ki te matotoru taiepa o tetahi. Waihoki rite e te tikanga o putorino maka-rino. Ko tenei tikanga te noa tino. Mā te makanga turai e ahei te hua putorino ki taiepa 80 ki te 300 mm (i runga i te taputapu e whakamahia ana rānei) o. Ko te mea anake e kia pupuri tino koutou i roto i te ngakau, ko te meka e ki tenei tikanga, puta ahotea ā-i roto i te reni. Na reira, i muri i te whiwhi castings tika ki te whakahaere i kōpeke ana.

rite tikanga makanga turai me te hoki tahi atu wahi preform, e riro te tinana o te revolution. whakamahia rawa rongonui tikanga pū whakaitinga te i roto i te hanga o billets i konganuku kore-ferrous (tenei tikanga ka taea ki a koe te whakaora rauemi utu).
