I roto i te tikanga ki te whakahaere i whakarewa rere pātea hanga, ka taea te tango mehua whaitake ki te whakaiti deformation ātete me te whakaora pūngao o te taputapu. Ko te tikanga, ka whakamahia nga huarahi e whai ake nei hei whakatutuki:
1) mohio ki nga ahuatanga o te hanga rauemi, me te whiriwhiri i te pāmahana deformation whaitake, te tere deformation me te tohu deformation.
2) ki te whakatairanga i te homogenization o te hanganga matū me te āhua whakahaere o te rauemi, pērā i te ingot maitai nui ki te koranu tiketike, maimoatanga homogenization i te pāmahana tiketike, kia rite ki te whakapai ake i te kirihou o te rauemi.

3) whiriwhiri me te whakatau i te tukanga deformation tino pai, pērā i te hanga i te deformation uaua, iti plasticity o tiketike koranu maitai te hanga, i roto i te tikanga ki te whakararuraru i te mata o te rauemi i roto i te āhua o te pēhanga, ki te ārai i te mānukanuka tangential me te whakatupuranga o kapiti, ka taea te whakamahi ki te hanga i te pōkai tukanga upsetting.
4) whakamahi taputapu rerekē ki te mahi, me te whakamahi tika o taputapu e taea te whakapai ake i te kore-orite o deformation.Ki te unuhia i roto i te momo tuaka roa whati, ka taea e te whakamahi V hanga paepae a tawhio noa ranei, kia piki te pehanga mata forging, reira te plasticity pai ake ahua, a ka taea te aukati i te mata whati me te ngakau ki te whakaputa i te kapiti.
5) whakapai ake i te tikanga mahi ki te whakaiti i te pānga o te waku me te meangiti i roto i te hanga pire, me te karo upsetting cracking.Mo te tauira, mo te hanga o panekeke o rauemi kirihou iti, ka taea te whakaoti i te reira e te tukanga o te whakararuraru i nga wahi e rua kōaro-iho kotahi, ka huri i ia wahi 180° mo te whakararuraru tuarua.

6) te whakatamarikitanga o mehua whakahinuhinu pai ake e taea te whakapai ake i te huru mata o te hanga mongamonga me pokepokea ai, whakaiti i te mana o te waku me te whiwhi ara deformation, na te whakaiti i te ātete deformation.
