He aha ka ʻōpala? ʻO ka mold ka mea hana kumu nui, a ʻo ka mold maikaʻi kahi hōʻoia nui no ka hana ma hope; Pehea ka hana ʻia ʻana o ka ʻōpala? He paʻakikī ka hana ʻana i nā mole? ʻOiai ʻo ka hana ʻana o ka mold no ka ʻāpana o ka hana mechanical, ma muli o nā ʻano a me ke ʻano hana o nā mold, paʻakikī ke hana i nā ʻāpana mold i ka mīkini kuʻuna.
ʻO ka'ōpala he mea hana hana, no laila,ʻoi aku ka kiʻekiʻe o ka paʻakikī o ka meaʻeleʻele ma mua o nā'āpana. No ka laʻana, hana maʻamau nā ʻāpana i hana ʻia o nā mea hoʻoheheʻe anuanu i nā mea hana paʻakikī a i ʻole carbide cemented, no laila paʻakikī ke hana ʻia e nā ʻano ʻoki kuʻuna.
ʻO ka maikaʻi o ka hana ʻana o ka mold ka nui o ka dimensional accuracy, shape accuracy, position accuracy (collectively called as machining accuracy), surface roughness, etc. Hoʻoholo ʻia ka pololei machining o ka mold e nā koi o nā ʻāpana a me ka hoʻolālā mold. ʻO ka ʻōlelo maʻamau, ʻo ka pololei o ka ʻāpana hana o ka mold he 2 ~ 4 mau māka kiʻekiʻe ma mua o nā ʻāpana, a ke hoʻomalu ʻia ka ʻae ʻana o ka hana ʻana i loko o ± 0.01mm, a pono kekahi i loko o ka laulā micrometer; ʻAʻole ʻae ʻia ka ʻili o ka mīkini e loaʻa nā hemahema, a ʻoi aku ka liʻiliʻi o ka roughness ma mua o 0.8&mum.
ʻO ka ʻōlelo maʻamau, ʻo 1 ~ 2 mau ʻāpana wale nō e pono ai e hana i kahi ʻāpana, a ʻo ka hammer forging mold i hana ʻia i loko o nā pūʻulu liʻiliʻi, no laila ua hana ʻia nā ʻōpala i hoʻokahi ʻāpana, a ʻo ka hapa nui o lākou e hana ʻia e nā ʻano kuʻuna. He lōʻihi ka pōʻaiapili hana a he kiʻekiʻe ke kumu kūʻai o nā lako a me nā mea hana.
