ʻO ka ʻoliʻoli ʻana i nā pahi ʻili

Hoʻopili ʻia nā ʻili ʻili i ka mānoanoa i makemake ʻia a no ka hōʻoia ʻana i nā ana like ʻole o ka maka ʻili. Ma hope o ke kuʻi ʻana a i ʻole ka sintering o nā lau ʻike, aia kekahi mau ʻōpala a me nā hemahema ʻē aʻe ma ka substrate, e pili ana i ka maikaʻi o ka helehelena. ʻO ka poli ma mua o ka pena e hoʻomaikaʻi nui i ka maikaʻi o ka helehelena a hoʻonui i ka hoʻokūkū huahana. Loaʻa i ka Donglai Metal ka mea wili ʻili nui no nā ʻili ʻili pōʻai, a hiki i 2,200 mm anawaena. ʻO ka poli ʻana o nā lau a hiki i ka 800 mm ke hana pū ʻia ma kahi mīkini polishing piha.
