Ma waena o nā ʻenehana wela i kēia manawa, hōʻike ʻia nā wela wela pin-fin i kahi hopena hoʻomaha maikaʻi. He ʻāpana ili nui ko lākou e pili ana i kekahi puʻupuʻu wela ʻē aʻe. Eia kekahi, hana ʻia nā ʻāpana wela pin-fin me nā alumini alumini thermally conductive a i ʻole keleawe. He kumu a me kahi ʻano o nā pine i hoʻokomo ʻia. ʻO nā ʻāpana e like me ka nui o ka pā papa (ʻo ka wāwae a me ka mānoanoa), ka lōʻihi o ka pine, ka mānoanoa a me ka nui, a me nā mea (alumini, keleawe a i ʻole nā ​​​​mea ʻē aʻe) kūpono i ka hapa nui o nā kikoʻī. ʻO ka hopena, hiki ke maʻalahi ka hoʻopili ʻana i nā ʻili pin e kūpono i nā noi like ʻole e pili ana i nā haʻahaʻa wela e pili ana, nā wahi i loaʻa, a me ka ea.

Hoʻolālā a hana mākou i nā papa kumu Pin-Fin no ka ʻoihana uila uila. Hāʻawi kēia mau papa kumu i ka hoʻoili wela maikaʻi loa i loaʻa i kēia lā ma muli o kā mākou forging, machining, plating a me ka ʻenehana lapaʻau ʻili.
