1. Tukatuka huarahi:
Kowiri tira tukatuka putorino profiled kua wehea ki te niao me te niao maha;
he tukanga niao o te putorino kowiri tira i roto i te tukatuka putorino me te niao raina production, i te huinga o te abrasive extrusion deformation o te ngongo niao ki te whakaturia te huinga o motuhake-ahua paipa paerewa.
Ko te hanga-maha te nuinga o te whakakikorua tuarua, kei roto i te ngongo porowhita, i te ngongo tapawha ranei i runga i te miihini ano i muri i te miihini ki roto i te ngongo ki roto i te huinga rerekee ngongo motuhake.
2. Rerekētanga ki te niao tuatahi me te niao tuarua:
Ko te kounga o te tukanga hua ko te tikanga pai ki te o mua, engari te kounga motuhake me te tukanga whakaritenga e kore e tino rerekē, etahi kowiri tira ahua ngongo i roto i te ripeka-wahanga o te tohu matatini o te matatini, me te kore e taea e te take kotahi o kōwhiringa tuarua wā neke atu ranei Molding, te reira hoki Hainamana kowiri tira hangarau tukatuka putorino me te taputapu e kore e taea te whakatutuki i te taumata matatau ake o te whiriwhiri e tika ana.
3. Taupānga:
Ko nga ngongo ahua kowiri tira e whakamahia nuitia ana i roto i nga momo hanganga, taputapu me nga waahanga miihini
4. Rerekētanga ki te ngongo a tawhio noa:
Ko te paipa kowiri tira te ahua o te putorino he nui ake te momeniti o te inertia me te whakawhiti-waahanga modulus, he nui ake te piko me te kaha torsional, ka taea te whakaiti i te taumaha o te hanganga, te whakaora i te maitai.
