Nā ʻāpana kaha kiʻi hohonu metala

Me ka ulu ʻana o ke kaiāulu, ua hoʻomohala ʻia nā ʻāpana stamping i nā ʻoihana like ʻole, a ʻike ʻia nā ʻāpana stamping ma nā wahi āpau i ke ola o kēlā me kēia lā. Nui nā ʻano o nā ʻāpana hana hoʻopaʻa ʻia, i hoʻohana ʻia ma nā ʻano āpau o ke ola, ametala ʻāpana kaha kiʻi hohonu ʻo ia kekahi o lākou. Metalakiʻi hohonuhehiʻo ia ka hoʻohana ʻana i ka mīkini stamping e hoʻololi i nā mea metala i loko o ka cylindrical, rectangular, trapezoidal, spherical a me nā ʻāpana conical me ka hoʻohana ʻana i ke kaʻina o ka huki ʻana i nā apo a i ʻole nā ʻāpana metala. Inā hui pū me nā kaʻina hana stamping ʻē aʻe, hiki ke hana ʻia nā ʻāpana paʻakikī a pololei hoʻi. ʻO ka maʻamau, e hoʻopili pololei ka ductility o ka metala i ka hana hana a me ka maikaʻi o ke kaha kiʻi hohonu, no laila e hoʻohana mau ʻia nā flakes metala e like me nā mea maka no ka stamping. ʻO ka hohonu hukianaʻāpanasʻO ke kaʻina hana he kaʻina hana maikaʻi loa no ka mālama ʻana i nā kumuwaiwai. ʻO nā mea tensile maʻamau he alumini alumini, kila, zinc, keleawe a me nā metala ʻē aʻe.
