He aha nā mea pono i kūpono no ka ʻenehana hoʻoheheʻe ʻia i ka pauka metala?

1.He aha ka ʻenehana hoʻoheheʻe ʻia ka pauda metala?

 

I ka honua opauda metallurgy,hoʻoheheʻe ʻia ka pauka metala (MIM) he ʻano ʻenehana hoʻoheheʻe ʻupena kokoke. ʻEono kaʻina hana i ke kaʻina MIM: ka hana ʻana i ka pauka, hoʻohui ʻia me ka mea hoʻopili, hoʻoheheʻe ʻia, hoʻohui i ka mea hoʻoheheʻe a me ka debinding, sintering a me ka hoʻōla ʻana, a me ka hoʻopau ʻana.

 

ʻO nā kikoʻī penei: Pono ka MIM hana i kahi ʻāpana metala pauda liʻiliʻi loa, ma ke ʻano he 0 a hiki i 30 microns, ma ke ʻano kiʻekiʻe kiʻekiʻe o ka wai atomization a i ʻole ke ʻano atomization gas; Hoʻohui ʻia ka pauka a me ka mea hoʻopili: ua hui pū ʻia ka pauka metala a me ka mea hoʻopili organik i loko o nā ʻāpana, a ua wela nā ʻāpana hui i kahi kūlana plasticized; ʻO ka hoʻoheheʻe ʻana: ma o ka mīkini hoʻoheheʻe ʻia e ʻoki i ka hui ʻana i loko o ka lua polū, e hana ana i nā ʻāpana o ka blank mua; Mea hoʻopili degreasing: ma ke kemika a i ʻole ke ʻano hoʻoheheʻe wela e wehe i ka mea hoʻopaʻa i nā ʻāpana billet, e loaʻa i ka metala a i ʻole kahi mea hoʻopaʻa liʻiliʻi wale nō nā ʻāpana billet; Sintering a curing: hoʻouna ʻia nā ʻāpana i ke kapuahi sintering no ka hoʻōla ʻana e hoʻoneʻe hou i ke koena mea hoʻopili; Ma hope o ka mālama ʻana: ma o ka hoʻopau ʻana i ka wela, ka mālama ʻana i ka wela kemika, ka mālama ʻana i ka mahu a me nā mea ʻē aʻe e hōʻemi ai i nā pores o loko o nā ʻāpana, hoʻomaikaʻi i ka nui o nā ʻāpana, hoʻomaikaʻi i ka ikaika o nā ʻāpana, ka pale ʻana i ka corrosion a me ke kūpaʻa ʻana, etc., e hana i nā ʻāpana hope.

 

2, He aha nā mea pono e kūpono i ka ʻenehana hoʻoheheʻe ʻia i ka pauka metala?

 

Hoʻohana nui ʻia ʻo China MIM i nā huahana like ʻole, me nā wati, nā mea lapaʻau liʻiliʻi, nā mea haʻuki, nā mea kaua māmā, a me nā mea ʻē aʻe. ʻO ka ʻenehana MIM, ʻo ia kekahi o nā ʻenehana hoʻohui kūpono i ka mīkini kuʻuna, hiki ke hoʻohana i nā mea a hana i nā huahana me nā hale paʻakikī i ʻoi aku ka maikaʻi ma mua o ka mīkini kuʻuna.

 

Hiki ke hoʻokaʻawale ʻia ka hana e pili ana i ka ʻenehana MIM i kēia mau kūlana:

 

1, ma ke kaʻina ʻoki kuʻuna a wili paha, nui loa ka poho waiwai, a he mau ʻāpana lōʻihi ka manawa hana, kūpono no ka ʻenehana MIM e hōʻemi i ke kumukūʻai.

 

2, hiki i ka MIM ke hana nui, hoʻokō i kekahi mau kūlana hana nui, akā ʻoi aku ka haʻahaʻa o ke koi ma mua o ke kumukūʻai o nā ʻāpana wehe ʻana i kūpono no ka ʻenehana MIM.

 

3. No nā metala paʻakikī e ʻoki, e like me ka titanium a me ka nickel alloy, hiki ke noʻonoʻo ʻia ka ʻenehana MIM no ka hana ʻana. E hoʻomaikaʻi ʻia ka pololei o nā huahana i hoʻohālikelike ʻia me ka hana kuʻuna, a e mālama nui ʻia nā mea waiwai.

 

4, me ka paʻakikī geometric shape, e like me ka pae ili, klooping, cross passage a me nā ʻāpana ʻē aʻe, ʻo ia mau ʻāpana i ka metallurgy pauka kuʻuna he paʻakikī ke hoʻokō, i ke kaʻina ʻokiʻoki pono e hoʻololi i ke kahua hana o nā ʻāpana multi-axis a i ʻole nā ​​ʻāpana multi-reference, kūpono no ka hana ʻenehana MIM.

 

5. ʻO nā ʻāpana e pono e hana ʻia e ka hui pū ʻana o nā mea like ʻole, e like me nā ʻāpana i hana ʻia e ka hui ʻana o nā mea metala a me nā mea seramika, a i ʻole nā ​​ʻāpana i hoʻopaʻa ʻia e nā mea like ʻole, e like me ka magnetic magnetic - soft magnetic, magnetic - non-magnetic, conductive - insulating material.

 

3, He aha nā mea kūpono no ka ʻenehana hoʻoheheʻe ʻana i ka pauka metala?

 

Hoʻohana ʻia ka ʻenehana MIM i kahi ākea ākea o nā mea. Ma ke kumu, ʻoiai ka lōʻihi o ka helu hoʻoheheʻe ʻana ma luna o ka mahana sintering, hiki ke hana ʻia nā mea pauka e ka ʻenehana MIM. Ke noʻonoʻo nei i ka hoʻokele waiwai, i kēia manawa maʻamau i hoʻohana ʻia nā mea i hoʻohana nui ʻia i ka hao kumu, nickel base, haʻahaʻa alloy, paʻa paʻa, etc. JIEHUANG CHIYANG asMea hana ʻāpana MIMhāʻawi i ka ferrous a me ka nickel-based alloy metala pauka lepo no ka hoʻoheheʻe ʻia ʻana o ka pauda metala, me nā mea hōʻailona hana i hiki i ka pae kiʻekiʻe o ka ʻoihana.
