Hoʻomau ʻia ka hana ʻana o nā paipu wiliwili a hiki ke hana i nā paipu kila lōʻihi loa. Hoʻemi kēia kaʻina hana i ka pohō ʻoki poʻo a me ka huelo me ka hoʻonui ʻana i ka hoʻohana ʻana i ka metala ma 6% a 8%. E hopena kēia i ka mālama kālā a me ka pono no kā mākou mea kūʻai aku.

ʻO kā mākounā paipu i hoʻopaʻa ʻia me ka ʻōwilihāʻawi i ka maʻalahi o ka hana ʻana ma mua o nā paipu wili pololei kuʻuna. Maʻalahi ke hoʻololi a hoʻoponopono i nā ʻano like ʻole, e kūpono ai lākou no nā papahana e pono ai ka hoʻololi a me ka hoʻopilikino ʻana. Eia kekahi, ʻo ka mechanization a me ka automation hiki o kā mākou mau paipu wili wili e ʻae iā lākou e hoʻokō maʻalahi ʻia i nā ʻano ʻoihana like ʻole.

Hana ʻia kā mākou mau paipu wiliwili i nā kūlana kiʻekiʻe loa e hoʻokō ai i nā koi o ka ʻoihana. Hoʻohana mākou i ka ʻenehana hou loa a me ka ʻenekinia pololei e hana i nā huahana e ʻoi aku ma mua o nā mea i manaʻo ʻia. Hoʻāʻo pono ʻia kēlā me kēia paipu a nānā ʻia e hōʻoia i ka hoʻokō ʻana i nā kikoʻī e pono ai no nā noi paipu kinoea.

Ma waho aʻe o nā pono loea, ua hoʻolālā ʻia kā mākou mau paipu wiliwili me ka noʻonoʻo ʻana i nā pono o nā mea kūʻai aku. Mai ke kau ʻana a hiki i ka mālama ʻana, ua hoʻolālā ʻia kā mākou mau paipu wiliwili no ka ʻoluʻolu loa.
