ʻO Cold forging, ʻike ʻia hoʻi he cold volume forging, he hana hana a me ke ʻano hana. ʻO ke kumu like me ke kaʻina hana stamping, ʻo ke kaʻina hana hoʻoheheʻe anuanu i haku ʻia me nā mea waiwai, nā mold a me nā mea hana. Akā ʻo ka mea i ka hana stamping ka mea nui o ka pā, a ʻo ka mea i loko o ka hana hoʻoheheʻe anuanu ʻo ia ka uea disk. Ua kapa ʻia ʻo Iapana (JIS) ʻo cold forging (cold forging), Kina (GB) i kapa ʻia ke poʻo anu, ma waho o ka hale hana screw e like me ke kāhea ʻana i ke poʻo.

ʻOkoʻa ka hoʻohana ʻana i ka pahu kila e like me ka ikaika o ka hoʻohana ʻokoʻa o ka wahi, no laila pehea e hoʻoponopono ai i ka pae ikaika? He 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, 9.8, 10.9, 12.9, 9.8, 10.9, 12.9, 9.8, 10.9, 12.9, 9.8, 10.9. nā helu, e hōʻike ana i ka waiwai o ka ikaika tensile nominal a me ka ratio flexion o nā mea bolt kūkulu kila.

No ka hana ʻana i nā mea hoʻopaʻa paʻa, ʻo ka mālama ʻana i ka ʻili he kaʻina me ka hiki ʻole, he nui nā mea kūʻai aku e nīnau e pili ana i nā mea hoʻopaʻa uila, ke ala o ka mālama ʻana i ka ʻili, ka pūnaewele maʻamau e like me ka ʻike i hōʻuluʻulu ʻia e pili ana i ka ʻili o nā mea hoʻopaʻa paʻa i nā ala hana maʻamau ʻewalu mau ʻano. o nā ʻano, e like me: ʻeleʻele (uliuli), phosphating, hot dip zinc, dacromet, uila galvanized, chrome plating, nickel and zinc impregnation. ʻO ka hoʻomaʻamaʻa ʻana i ka ʻili o ka mea hoʻopaʻa paʻa ma o kekahi ʻano hana e hana i kahi papa uhi ma luna o ka ʻili o ka mea hana, ʻo kāna kumu e hana i ka ʻili o ka huahana i ka nani, ka hopena anti-corrosion.
