Ua hoʻomohala ʻia ka Thermo-mechanical controlled processing (TMCP) no ka ʻōwili ʻana i mea e loaʻa ai ka ikaika kiʻekiʻe a me ka paʻakikī a hiki i ka haʻahaʻa haʻahaʻa no ka pā, a he nui nā noi e like me ka hana maoli. I ka hihia o ka forging, aia kekahi mau hiʻohiʻona i hoʻohana ʻia TMCP. No nā ʻāpana kalaiwa kaʻa, ʻo ka hōʻemi ʻana i ke kaumaha kekahi o nā ala kūpono loa e hōʻemi i ka hoʻohana ʻana i ka wahie no ka hoʻemi ʻana i ka hoʻomehana honua. Ma ke noi ʻana o TMCP no ke kaʻina hana forging, i kapa ʻia ʻo ka forging controlled, ua hoʻomaikaʻi maikaʻi ʻia nā waiwai mechanical o nā ʻāpana forged i hiki iā ia ke alakaʻi i ka hōʻemi kaumaha.
