ʻO ka hoʻopaʻa ʻana wela, ʻo ia hoʻi ke kala ʻana i ka metala hakahaka ma luna o ka wela o ka recrystallization i hana ʻia.Nā hiʻohiʻona: e hōʻemi ana i ke kūpaʻa deformation o nā metala, no laila e hōʻemi ana i ka ikaika forging maikaʻi ʻole e pono ai e deform i ka mea, no laila e hoʻemi nui i nā lako forging tonnage;ke hoʻololi i ke ʻano o nā ingots i hoʻolei ʻia i ke kaʻina forging ma hope o ka recrystallization e lilo i ʻano hoʻoheheʻe koʻikoʻi ka hui hou o nā hua liʻiliʻi, a e hoʻemi i nā hemahema o ka hale hoʻoheheʻe e hoʻomaikaʻi i nā waiwai mechanical o ke kila;He paʻakikī ka hoʻomaikaʻi ʻana i ka ductility no kekahi o nā mea palupalu i nā haʻahaʻa haʻahaʻa i ke kila kila kila kiʻekiʻe, ʻo ia ka mea nui.E pili ana i ka nui deformation kū'ē i ka lumi wela, he ilihune metala plastic mea.Hot metala forging ana wela e pili ana i ka wela a me ka wela hoomaka ana e forge i kekahi manawa ma waena o ka hopena o ka forging wela, i mea e pale ai overheating, puhi pono e hoʻoholo pololei i ka wela forging mua a me ka wela forging hope.ʻO ke ala maʻamau, ʻo ia ka hoʻomohala ʻana i ka wela wela o ka hao-carbon equilibrium kiʻi ʻia i ke kumu kila.

Ma lalo o ka mahana recrystallization o ka mea hana, hana ʻia ka forging ma kahi mahana ma lalo o ka pane.Iecaianoaaiiuo maa i ka palaka unheated e kapaia anu forging forging.Ma lalo o ke anuanu forging wela deformation kū'ē o ka mea i ka hapanui liʻiliʻi, plastic a me kekahi alumini alloys maikaʻi, a me kekahi keleawe alloy, haʻahaʻa kalapona kila, kalapona kila, haʻahaʻa alloys kila.ʻO ka hoʻoheheʻe ʻana i ka maikaʻi o ka ʻili maikaʻi, ka pololei kiʻekiʻe, hiki ke hoʻololi i kekahi o ka ʻoki.Hiki ke hoʻoikaika a hoʻomaikaʻi i ka ikaika o nā ʻāpana me ka hoʻoheheʻe anuanu.ʻO ka ʻenehana forging anuanu e ʻoi aku ka kiʻekiʻe ma mua o ka mahana o ka hoʻokumu ʻana i ka precision forging a me ka forging, precision forming field i kona mau pono kūikawā.ʻO ke kaʻina hana hoʻoheheʻe anuanu me ka hoʻohana ʻana i ka hoʻopau bore maikaʻi, ka pololei o ka dimensional, ka ikaika o ka ʻili, hoʻolōʻihi i ke ola o ka barela, ka pololei o ka pana ʻana e like me ka piʻi ʻana o ka pū, a me ka maʻalahi o ka hana ʻana i ka barela tapered, hiki ke hoʻemi ʻia ka maikaʻi.
