ʻO ka Metal Injection Molding (MIM) kahi ʻano hou o ka ʻenehana ʻenehana Powder metallurgy, i hoʻomohala ʻia mai ka pauka injection molding (PIM) o nā ʻāpana seramika. ʻO nā ʻanuʻu hana nui o ka Metal Injection Molding penei: ka hui ʻana o ka pauka metala a me ka binder-granulation-injection molding-degreasing-sintering-ma hope o ka mālama ʻana-hopena huahana, kūpono ka ʻenehana no ka liʻiliʻi, paʻakikī, hana kiʻekiʻe ka hana nui ʻana Powder metallurgy ʻāpana, e like me nā mea i hoʻohana ʻia e ka ʻoihana wati Swiss e hana i nā ʻāpana wati. I nā makahiki i hala iho nei, ua ulu wikiwiki ka ʻenehana MIM, ʻo nā mea e pili ana: Fe-Ni alloy, stainless steel, mea kila, kiʻekiʻe kikoʻī gravity alloy, cemented carbide, titanium alloy, ni-based superalloy, intermetallic compound, alumina, zirconia a pēlā aku. ma. Pono ka ʻenehana Metal Injection Molding (MIM) i ka liʻiliʻi o ka nui o ka pauka ma mua o ka micron a ʻaneʻane spherical ke ʻano. Eia kekahi, koi ʻia ka haʻahaʻa haʻahaʻa, ka vibrating density, ka ratio o ka lōʻihi i ke anawaena, ke kihi slope kūlohelohe a me ka puʻupuʻu ʻāpana nui. I kēia manawa, ʻo nā ʻano kumu nui o ka hana ʻana i ka pauka no ka ʻenehana hoʻoheheʻe metala ʻo ka atomization wai, atomization gas a me ke ʻano hui carbonyl. ʻO nā lama pauka maʻamau i hoʻohana ʻia no ka injection o nā metala kila kila: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, etc. ʻO ke kaʻina hana o ka atomization wai penei: ke koho ʻana i ke kila kila kila-he hoʻoheheʻe ʻia i ka umu induction induction-composition adjustment-deoxidation a me ka slag removal-atomization a me ka pulverization-quality detection-screening-packaging a me ka mālama ʻana, nā mea hana nui i hoʻohana ʻia: ka umu induction medium-frequency, ka pauma wai kiʻekiʻe, ka mea hoʻoheheʻe i pani ʻia, ka pahu wai kahe, ka nānā ʻana a me nā lako paʻi, nā mea hoʻāʻo.

ʻO ke kaʻina hana oʻātomi kinoeapenei:

ke koho ʻana i ke kila kila kila-he hoʻoheheʻe ʻia i ka umu induction induction medium-composition adjustment-deoxidation a me ka slag removal-atomization a me ka pulverization-quality detection-screening-packaging a me ka waiho ʻana. ʻO nā mea hana nui i hoʻohana ʻia ʻo: medium frequency induction melting furnace, kumu nitrogen a me nā mea atomization, circulating water tank, screening and packaging equipment, testing equipment. Loaʻa i kēlā me kēia ʻano nā pono ponoʻī a me nā pōʻino: ʻO ka wai Atomization ke kaʻina pulverizing nui, ʻo kona kiʻekiʻe kiʻekiʻe, ʻoi aku ka maikaʻi o ka hana nui, hiki ke hana i ka pauka maikaʻi, akā ʻaʻole maʻamau ke ʻano, e kūpono i ka mālama ʻana, akā ʻo ka hoʻohana hou ʻia ka binder, pili i ka pololei. Eia kekahi, ʻo ke kiʻi oxidation i hana ʻia e ka hopena o ka wai a me ka metala ma ke kiʻekiʻe wela e pale i ka sintering. ʻO ka Gas Atomization ke ala nui e hana ai i ka pauka no ka ʻenehana hoʻoheheʻe metala. ʻO ka pauka i hana ʻia e ka atomization gas he spherical, me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka liʻiliʻi o ka binder e pono ai a me ka formability maikaʻi, akā ʻoi aku ka haʻahaʻa o ka pauka ultra-fine, kiʻekiʻe ke kumukūʻai a ʻilihune ke ʻano o ka mālama ʻana i ka waiwai, c, N, H, Loaʻa ka ʻO i loko o ka binder i ke kino i hoʻopaʻa ʻia. ʻO ka pauka i hana ʻia e ke ʻano carbonyl he kiʻekiʻe i ka maʻemaʻe, paʻa i ka hoʻomaka ʻana a maikaʻi loa i ka nui o nā ʻāpana. He kūpono loa ia no MIM, akā no Fe, Ni a me nā pauka ʻē aʻe, ʻaʻole hiki ke hoʻokō i nā koi o nā ʻano. I mea e hoʻokō ai i nā koi o ka pauka no ka hoʻoheheʻe ʻana i ka metala, ua hoʻomaikaʻi nā hui he nui i nā ʻano o luna a hoʻomohala i nā ʻano micro-atomization a me laminar atomization. I kēia manawa, ʻo ia ka wai atomized pauka a me ke kinoea atomized pauka i hui pū ʻia, ʻo ka mea mua e hoʻomaikaʻi i ka density o ka compaction, ʻo ka hope e mālama i ke ʻano. I kēia manawa, hiki i ka hoʻohana ʻana i ka pauka atomizing wai hiki ke hana i ke kino sintered me ka nui o ka nui ma mua o 99%, no laila hoʻohana wale ʻia ka pauka atomizing wai no nā ʻāpana nui, a hoʻohana ʻia ka pauka atomizing kino no nā ʻāpana liʻiliʻi. I nā makahiki ʻelua i hala iho nei, ua kūkulu ʻo Handan Rand Atomizing Pulverizing Equipment Co., Ltd. i kahi ʻano hou o ka atomizing pulverizing mea hana, ʻaʻole hiki ke hōʻoia i ka hana nui o ka wai atomizing a me ka pauka ultrafine, akā e noʻonoʻo pū i ka nā mea maikaʻi o ke ʻano o ka pauda spherical.
