Ma hope o ka hele ʻana i ka forging, hiki ke hoʻomaikaʻi ʻia ke ʻano metala a me kona ʻano mechanical. ʻO ke kristal nui mua a me ka hua kristal prismatic e lilo i lahilahi a like ka liʻiliʻi, a laila hoʻonohonoho hou ʻia e hana i ka a-liquation, looseness, air bubble a me ka slag i hoʻokomo ʻia e kaomi a lilo kona ʻano i kokoke a paʻa e hoʻomaikaʻi ai i ka plasticity a me ka ʻano mechanical o ka metala. Akā ʻoi aku ka ʻino o ka ʻano mechanical o ka ʻāpana hoʻolei ma mua o nā ʻāpana forging ʻē aʻe o ka mea like. Eia kekahi, hiki i ka forging ke hōʻoia i ka hoʻomau ʻana o ke ʻano fiber metala a mālama i ke ʻano fiber a me ke ʻano o waho e like, hoʻopiha i ka metala a hōʻoia i ka lōʻihi o ke ola a me ka maikaʻi o ka mechanical. ʻO ke ʻano hana o ka hoʻohana ʻana i ka forging mold pololei. ʻAʻohe mea like o ka kaomi anu, ka paʻi mahana i ka hana ʻana i ka ʻāpana forging.
