ʻO ka mīkini pōhaku sima he ʻano mea hana mechanical e hoʻohana ana i ka slag, slag, lele lehu, ka pauka pōhaku, ke one, ka pōhaku a me ka sima e like me nā mea maka, hoʻohālikelike ʻepekema, hui pū me ka wai, a me ke kaomi kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe, poloka hollow a i ʻole ke kala kala ʻia e ka mīkini hana pōhaku.

Nui nā ala e hana ai i nā pōhaku lepo me ka mīkini brick sima. Loaʻa i nā ʻano hana brick ʻokoʻa nā hopena hana brick ʻokoʻa. ʻO ke ala maʻamau ka hoʻohana ʻana i ka hydraulic vibration forming. He nui nā pōmaikaʻi o kēia ʻano hana no ka hana ʻana i nā pōhaku. I ka manawa like, ʻoi aku ka maikaʻi o ka pōhaku sima. No laila he aha nā mea maikaʻi o ka hydraulic vibration molding?

Hiki i ka mīkini brick sima ke hoʻohana i ke ʻano hoʻoheheʻe vibration e hana i ka hopena ʻoi aku ka maikaʻi. I ka wā e haʻalulu ai, hiki iā ia ke hoʻokaʻawale i nā mea maka. ʻAʻohe hewa o ka pōhaku sima, a maikaʻi loa ka maikaʻi o ka pōhaku sima i hana ʻia. ʻO ke kaʻina hana o ka mīkini brick sima he pōkole, hiki ke hoʻokō i ke ʻano hana pōkole. ʻOi aku ka nui o nā pōhaku lepo sima a nui loa ka hopena, no laila ʻoi aku ka maikaʻi o ke kaiapuni a me ka mālama ʻana i ka ikehu. ʻOi aku ka nui o ka mīkini brick sima i ka wā e lawe ai i nā mea waiwai, ʻo ka pōmaikaʻi nui ʻoi aku ka maʻalahi o ka hoʻomaʻemaʻe a hoʻololi i ke ʻano, ʻoi aku ka maʻalahi o ke ʻano o ke kaʻa i loko o ke kau ʻana o waho a ʻoi aku ka ikaika o ka hopena wela, ʻoi aku ka nui o ka hana ʻana o ka mīkini brick sima. Hoʻohui ka mīkini pōhaku kiʻekiʻe kiʻekiʻe i ka hiki ke hoʻohui i ka mechanical a me ka uila, hiki ke mālama pono i ka manpower a me nā kumu waiwai, a hiki ke mālama i ka hoʻopili ʻana o ka hui maloʻo maloʻo.
