Ke kalaiwa anaʻo ka hana ʻana i ka metala paʻa ma luna a me laloke kalaiwa anamake i loko o ka mold keena i koi 'ia ka plastic kahe molding, no laila, e loaa i ke kinona o kanā kalaiwakūlike me ke keʻena mold, i kapa ʻia ʻo die forging.E like me ke ʻano paʻa o ka forging make, hiki ke hoʻokaʻawale ʻia i ka paʻa paʻa paʻa a me ka paʻamake forging.
1. Paʻamake forging ke kalaiwa anaʻO ka make o luna a me ka make lalo, i hoʻopaʻa ʻia ma ke poʻo hāmare a me ka ʻāpana anvil o ka hāmare forging die, ʻo ka alignment o luna a me lalo make e hōʻoiaʻiʻo ʻia e ka hammer die forging.I ka wā e hoʻopaʻa ai, waiho ʻia ka blank wela i loko o ke keʻena make haʻahaʻa, a na ke poʻo hāmare e hoʻokele i ka make o luna e hoʻoheheʻe, i kahe ka metala a hoʻopiha i ke keʻena make e hana i kake kalaiwa ana, a paʻi ʻia ka metala keu i loko o ke awāwa lihi lele e hana i ka lihi lele, a laila ʻoki ʻia ma hopeke kalaiwa ana. Make forgingnā ʻāpana me nā ʻano paʻakikī, pono e wehe i nā pahu make nomake forging, no laila e puka mālie ana ka billet i loko o kekahi mau pahu make, a hoʻopaʻa hope i ke ʻano i makemake ʻia i ka lua make hope.Paʻamake forgingloaʻa nā pōmaikaʻi o ka huahana kiʻekiʻe,maikaʻi ka maikaʻi forging,ʻano paʻakikī a me ka mālama ʻana i nā mea metala, ʻo ia ke ʻano kumu o ka makeke kalaiwa ana.Akā, pono ke kumukūʻaimake forginglako a make, ka nui o kake kalaiwa anakaupalena ʻia e ke tona o ka makeke kalaiwa anamea lako.No laila, kūpono wale ia no ka hana nui.

2.
