Hoolei hao hina hina o OEM
Hōʻike huahana
ʻO ka hao hina, a i ʻole ka hao hina hina, he ʻano mea hao me ka microstructure graphitic.Kapa mākou i kēia ʻano mea hao hina ma muli o ke kala hina o ka haki.No ka graphite lubricating i ka oki a me ka wawahi ana i na chips, hina hina he mea hoolele maʻamau ma muli o kona 'ano haʻahaʻa kumu kūʻai a me ka maikai machinability.Ma waho aʻe, no ka lubricate ponoʻī ʻana o ka graphite flakes, maikaʻi nō hoʻi ia i ka galling a me ke kūpaʻa.
ʻOi aku ka liʻiliʻi o ka paʻa ʻana o ka hao hina ma mua o nā hao hao ʻē aʻe ma muli o ka microstructure graphite.I ka hoʻolei ʻana, hiki i ka mea silika ke hoʻoikaika i ka pale corrosion maikaʻi a hoʻonui i ka wai i ka wā e hoʻolei ana.He mea maʻalahi ka hao hina e wili.Hoʻohālikelike ʻia me nā mea ʻē aʻehao hao, He haʻahaʻa ka ikaika tensile a me ka ductility ka hao hina;ʻo ia ke kumu i ʻaneʻane ʻole ka hopena a me ka haʻalulu o kēia ʻano mea.

I loko o kā mākou foundry, hiki iā mākou ke hana i ka hao hina hina ma lalo o ʻelua ʻano:
Hoolei Huhu Nalo: Ka mea wale nohoʻolei kālākaʻina hana no nā mea hao hao, he nui nā mea maikaʻi e hana ai i nā hoʻoheheʻe hao hina liʻiliʻi, e like me ke kumukūʻai mold i mālama ʻia, hoʻopōkole i ka pōʻai hana a hoʻomaikaʻi i ka hana hana.Me ke kaʻina hana hoʻoheheʻe ʻia, hiki iā mākou ke kōkua i kā mākou mea kūʻai aku e kiʻi i nā huahana kiʻekiʻe me ka hoʻopau maikaʻi ʻana o ka ʻili, a e hana ʻia nā hana mīkini liʻiliʻi.
Hoolei Sand Resin: ʻO ke kaʻina hana hoʻolei one nui no nā hoʻolei liʻiliʻi.E hoʻohālikelike me nā kaʻina hana hoʻoheheʻe one ʻē aʻe, ʻo ka hoʻolei ʻana i ke one resin he ʻano hoʻolei pololei ma kahi kokoke i ka hoʻolei ʻana.E like me ka rigidity maikaʻi o ke one resin a me ka ikaika kiʻekiʻe o ka hoʻoheheʻe ʻana i ke one i ka wā e hoʻolei ʻia ai, a laila hiki iā mākou ke hoʻopau pono i ka lua shrinkage, shrinkage defects o ka hao hina.
