Mai ka wanaʻao o ke kanaka, ua hōʻoia ka hana metala i ka ikaika, ka paʻakikī, ka hilinaʻi, a me ka maikaʻi kiʻekiʻe o nā huahana like ʻole. I kēia mau lā, ʻoi aku ka nui o kēia mau mea maikaʻi o nā ʻāpana forged i ka piʻi ʻana o nā mahana hana, nā ukana, a me nā koʻikoʻi.
Hana ʻiahiki i nā ʻāpana ke hoʻolālā i nā haʻahaʻa kiʻekiʻe a me nā koʻikoʻi. ʻO nā holomua hou i ka ʻenehana forging ua hoʻonui nui i ka laulā o nā waiwai i loaʻa i nā forgings.
Ma ka ʻoihana waiwai, nani nā huahana forged ma muli o ko lākou hilinaʻi ʻoi aku ka maikaʻi, hoʻomaikaʻi i ka hiki ke hoʻomanawanui, a me ka ʻoi aku ka maikaʻi o ka hana ʻana i nā forgings e hiki ke hana ʻia a hoʻoponopono hou ʻia e nā ʻano hana automated.
ʻAʻole ʻoi aku ka maikaʻi o ka pae o ka hilinaʻi o ke kūkulu ʻia ʻana ma ka forging e kekahi kaʻina hana metala ʻē aʻe. ʻAʻohe ʻeke kinoea i loko a i ʻole nā ​​​​waha i hiki ke hoʻokō ʻole ʻia ma lalo o ke kaumaha a i ʻole ka hopena. ʻO ka manawa pinepine, kōkua ke kaʻina hana forging i ka hoʻomaikaʻi ʻana i ka hoʻokaʻawale kemika o ka waihona forging ma ka neʻe ʻana i nā mea kikowaena waena i nā wahi like ʻole a puni ka forging.
No ka mea hoʻolālā, ʻo ka paʻa pono o ka forgings, ʻo ia hoʻi nā mea palekana e pili ana i nā mea e pane pololei ana i kona kaiapuni me ka ʻole o ka hana kūikawā e hoʻoponopono ai i nā hemahema o loko.
I ka limahana hana, ʻo ka hilinaʻi ʻana o ka forgings ʻo ia ka hoʻemi ʻana i nā koi nānā ʻana, ka pane like ʻana i ka mālama ʻana i ka wela, a me ka machinability mau, nā mea āpau e hāʻawi i ka wikiwiki o ka hana ʻana a me nā kumukūʻai haʻahaʻa.
