1. Nā kaʻina hana like ʻole
Hana ʻia nā rim huila ma ka hoʻolei ʻana i ka wai alumini i hoʻoheheʻe ʻia i loko o kahi ʻāpana one, hoʻoluʻu i ke ʻano, a laila hoʻomaʻamaʻa ʻia (deburring, ʻokiʻoki i ke ʻano, polishing).
ʻO ka Forging, ma ka ʻaoʻao ʻē aʻe, hoʻohana i nā mole kila e kau ai i nā poloka alumini i hoʻomehana ʻia a palupalu i ke ʻano, a laila hoʻohana i ke kahakaha ʻana e hana ai. Ma hope o ka hoʻomaloʻo ʻana, hoʻomaʻamaʻa ʻia lākou e hana i ka huahana hope.
2. Na koina like ole
He mea maʻalahi ke kaʻina hana hoʻoheheʻe, ʻaʻole, a maʻalahi hoʻi e hana i nā mea nui, no laila he haʻahaʻa loa ke kumukūʻai, ʻoiai ʻoi aku ka paʻakikī o ka forging, no laila ua kiʻekiʻe ke kumukūʻai hana.
3. Nā kaumaha like ʻole
Ma muli o ka hoʻomau mau ʻana o nā poloka alumini i ka wā o ke kaʻina hana, ua paʻa loa ke ʻano molecular o nā huila forged ma hope o ka hana ʻana, e ʻae iā lākou e kū i ke kaomi kiʻekiʻe. No laila, ʻoi aku ka māmā o nā huila paʻa i ke kaumaha ma mua o nā huila hoʻolei like ʻole ka nui a me ka ikaika.
