ʻO ka Metal Injection Molding (MIM) kahi ʻano hou o ka ʻenehana Powder metallurgy, i hoʻomohala ʻia mai ka pauka injection molding (PIM) o nā ʻāpana keramika. 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-subsequent treatment-hopena huahana, kūpono ka ʻenehana no nā ʻāpana Powder metallurgy hana liʻiliʻi, paʻakikī, hana kiʻekiʻe, 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 kūpono e pili ana: Fe-Ni alloy, stainless steel, tool steel, high specific gravity alloy, cemented carbide, titanium alloy, ni-based superalloy, intermetallic compound, alumina, zirconia a pēlā aku. Pono ka ʻenehana Metal Injection Molding (MIM) i ka nui o ka ʻāpana o ka pauka ma lalo o ka micron a kokoke i ka poepoe ke ʻano. Eia kekahi, pono pū kekahi ka nui wehe, ka nui haʻalulu, ka lakio o ka lōʻihi i ke anawaena, ke kihi pali kūlohelohe a me ka hoʻolaha nui o ka ʻāpana. I kēia manawa, ʻo nā ʻano hana nui o ka hana ʻana i ka pauka no ka ʻenehana hoʻoheheʻe metala, ʻo ia ka atomization wai, ka atomization kinoea a me ke ʻano hui carbonyl. ʻO nā lama pauka i hoʻohana pinepine ʻia no ka hoʻokomo ʻana i nā metala kila kila: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, a pēlā aku. ʻO ke kaʻina hana o ka atomization wai penei: ke koho ʻana i nā mea maka kila kila - ka hoʻoheheʻe ʻana i loko o ka umu hoʻokomo alapine waena - ka hoʻoponopono ʻana i ka haku mele - ka wehe ʻana i ka oxidation a me ka slag - ka atomization a me ka pulverization - ka ʻike ʻana i ka maikaʻi - ka nānā ʻana - ka hoʻopili ʻana a me ka mālama ʻana, ʻo nā lako nui i hoʻohana ʻia: ka umu hoʻokomo alapine waena, ka pamu wai kiʻekiʻe, ka mea pulverizing pani, ka pahu wai e kaapuni ana, nā lako kānana a me ka hoʻopili ʻana, nā lako hoʻāʻo.

Ke kaʻina hana oka atomization kinoeapenei:

ke koho ʻana i nā mea maka kila kila-hoʻoheheʻe ʻia i loko o ka umu hoʻokomo alapine waena-hoʻoponopono ʻano-deoxidation a me ka wehe ʻana i ka slag-atomization a me ka pulverization-ʻike maikaʻi-nānā-ʻōpala a me ka mālama ʻana. ʻO nā lako nui i hoʻohana ʻia: umu hoʻoheheʻe induction alapine waena, kumu nitrogen a me ka mea atomization, pahu wai e kaʻapuni ana, nā lako kānana a me ka ʻōpala, nā lako hoʻāʻo. Loaʻa i kēlā me kēia ʻano hana kona mau pono a me nā hemahema: ʻO ka Atomization Wai ke kaʻina hana pulverizing nui, ʻo kona pono kiʻekiʻe, ʻoi aku ka hoʻokele waiwai o ka hana nui, hiki ke hana i ka pauka maikaʻi, akā ʻaʻole like ke ʻano, kahi e kūpono ai i ka mālama ʻana i ke ʻano, akā ʻoi aku ka nui o ka mea hoʻopaʻa i hoʻohana ʻia, e hoʻopilikia i ka pololei. Eia kekahi, ʻo ka ʻili oxidation i hana ʻia e ka hopena o ka wai a me ka metala ma ke ana wela kiʻekiʻe e pale aku i ka sintering. ʻO ka Gas Atomization ke ʻano nui e hana ai i ka pauka no ka ʻenehana hoʻoheheʻe injection metala. He poepoe ka pauka i hana ʻia e ka atomization kinoea, me ke kekelē oxidation haʻahaʻa, ʻoi aku ka liʻiliʻi o ka mea hoʻopaʻa e pono ai a me ke ʻano maikaʻi, akā haʻahaʻa ka hua o ka pauka ultra-fine, kiʻekiʻe ke kumukūʻai a maikaʻi ʻole ka waiwai mālama ʻano, c, N, H, O i loko o ka mea hoʻopaʻa he hopena i ke kino sintered. ʻO ka pauka i hana ʻia e ke ʻano carbonyl he kiʻekiʻe ka maʻemaʻe, paʻa i ka hoʻomaka ʻana a maikaʻi loa ka nui o ka ʻāpana. ʻOi aku ka kūpono no MIM, akā no Fe, Ni a me nā pauka ʻē aʻe wale nō, ʻaʻole hiki ke hoʻokō i nā koi o nā ʻano like ʻole. I mea e hoʻokō ai i nā koi o ka pauka no ka hoʻoheheʻe ʻana i ka metala, ua hoʻomaikaʻi nā ʻoihana he nui i nā ʻano i luna a hoʻomohala i nā ʻano hana micro-atomization a me ka laminar atomization. I kēia manawa, ʻo ka pauka atomized wai a me ka pauka atomized kinoea i hui pū ʻia, ʻo ka mea mua e hoʻomaikaʻi i ka nui o ka compaction, ʻo ka mea hope e mālama i ke ʻano. I kēia manawa, hiki i ka hoʻohana ʻana i ka pauka atomizing wai 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 kinoea no nā ʻāpana liʻiliʻi. I nā makahiki ʻelua i hala iho nei, ua hoʻomohala ʻo Handan Rand Atomizing Pulverizing Equipment Co., Ltd. i kahi ʻano hou o nā lako pulverizing atomizing, ʻaʻole hiki ke hōʻoia i ka hana nui o ka atomizing wai a me ka pauka ultrafine, akā e noʻonoʻo pū i nā pono o ke ʻano pauka poepoe.
