ʻO ka hoʻoili ʻana i ka punching he ʻano hana metala maʻamau e hana ana ma nā ʻano mea like ʻole, me ke kila kalapona, ke kila galvanized, ke kila kila, ka alumini a me ke keleawe. Loaʻa i kēia mau mea i kā lākou mau hiʻohiʻona ponoʻī a me nā mea maikaʻi i ka hana stamping.

ʻO ka mea mua, ʻo ke kila kalapona ka mea hoʻohana maʻamau i ka hana punching me ka hana maikaʻi a me ka ikaika, a kūpono no ka hana ʻana i nā ʻāpana a me nā ʻāpana like ʻole. Loaʻa i ke kila Galvanized nā waiwai anti-corrosion maikaʻi loa a kūpono no ka hana ʻana i nā huahana e koi ai i ka pale ʻana i ka corrosion, e like me nā ʻāpana kaʻa a me nā pahu mea hana hale.

Loaʻa i ke kila kila nā hiʻohiʻona o ka corrosion resistance, kiʻekiʻe wela ke kūpaʻa a me nā hiʻohiʻona nani, a kūpono no ka hana ʻana i nā lako kīhini, nā papa ʻaina, nā mea hoʻonaninani a me nā huahana ʻē aʻe. He māmā ke alumini, he maikaʻi ka thermal conductivity a me ka maikaʻi o ka mālama ʻana i ka ʻili, a kūpono no ka hana ʻana i nā ʻāpana aerospace, nā ʻāpana kaʻa a me nā pahu huahana uila.

He maikaʻi ka uila a me ka wela o ke keleawe a kūpono i ka hana ʻana i nā huahana e like me nā mea hoʻohui uila, nā uea, a me nā radiators. No laila, e like me nā pono huahana like ʻole a me nā koi ʻenekinia, hiki ke koho ʻia nā mea kūpono no ka hana punching e hoʻokō i ka hana huahana a me nā koi o ka maikaʻi. Ma nā noi kūpono, pono e noʻonoʻo pono ke koho ʻana i nā mea waiwai e like me ke ʻano mechanical o ka mea, ka pale ʻana i ka corrosion, ka hana ʻana, a me ke kumukūʻai e hōʻoia ai i ka huahana hope loa ka hana maikaʻi a me ka hoʻokele waiwai.
