ʻO ka mea maʻamau, hoʻokumu ʻia ke poʻo bolt e ke poʻomanaʻo poʻomanaʻo anu, ke hoʻohālikelike ʻia me ka ʻoki ʻana, ʻo ka fiber metala (metal wire) ma ke ʻano o ka huahana e hoʻomau ʻia, me ka ʻoki ʻole i ka waena, kahi e hoʻomaikaʻi ai i ka ikaika o ka huahana, ʻoi aku ka maikaʻi o nā waiwai mechanical. i loko o kekahi mau hana make.Simplex bit or multi-station automatic cold heading machine using the processing features of the original blank is made up of material size 5 to 6 meters long bar or weight is 1900-2000 kg of the size of the wire rod steel wire, the processing technology is the features of cold heading forming is not the cut sheet blank in advance, but USES the bar and need wire headset rod. ʻAʻole pono ka blank ma mua o ka huhū ʻana, e hoʻemi ana i ke anawaena a me ke kaomi ʻana. Ma hope o ka ʻoki ʻia ʻana o ka blank, e hoʻouna ʻia i ke keʻena hana huhū. ʻO ke ʻano hana a me ke kaʻina hana i hoʻohana ʻia.
