ʻO ka Metal Powder Injection Molding Technology (MIM) he mea hoʻoheheʻe lepo hou kokoke i ka ʻenehana hoʻoheheʻe ʻana i ka ʻupena i hoʻokumu ʻia e ka hoʻokomo ʻana i ka ʻenehana hoʻoheheʻe palaki hou i loko o ke kahua o ka pauka metallurgy.
Hoʻolauna ʻenehana
Hoʻohui ʻia ka ʻenehana hoʻoheheʻe ʻia me ka pauka metala i nā ʻenehana hoʻopaʻapaʻa like ʻole e like me ka ʻenehana hoʻoheheʻe ʻia, polymer chemistry, powder metallurgy technology, a me ka ʻepekema mea hao. Hoʻohana ʻo ia i nā mold e injection mold blanks a hana wikiwiki i nā kiʻi kiʻekiʻe, kiʻekiʻe-pololei, ʻekolu-dimensional paʻakikī ma o ka sintering. Nā ʻāpana hana. ʻO ka mea mua, ua kāwili ʻia ka pauka paʻa a me ka binder organik, a ma hope o ka granulation, ua hoʻokomo ʻia lākou i loko o ka lua mold me kahi mīkini hoʻoheheʻe i loko o kahi kūlana wela a me ka plasticized (~ 150 ° C) no ka paʻa ʻana, a laila hoʻokumu ʻia ka parison e ke kemika a i ʻole ka thermal decomposition. Hoʻopau ʻia ka mea hoʻopaʻa i ka huahana, a loaʻa ka huahana hope loa ma ka sintering a me ka densification.
ʻO kēia ʻenehana kaʻina hana ʻaʻole wale i nā pōmaikaʻi o nā kaʻina hana metallurgy maʻamau e like me ka liʻiliʻi o nā ʻanuʻu, ʻaʻole a i ʻole ka liʻiliʻi o ka ʻoki ʻana, a me nā pōmaikaʻi waiwai kiʻekiʻe, akā lanakila pū kekahi i nā hemahema o nā huahana metallurgy pauka maʻamau e like me nā mea pono ʻole, nā waiwai mechanical haʻahaʻa, a me ka paʻakikī i ka hana ʻana i nā paia lahilahi a me nā hale paʻakikī. He kūpono loa ia no ka hana nui ʻana o nā ʻāpana metala liʻiliʻi, paʻakikī a koi ʻia. Loaʻa iā ia nā hiʻohiʻona o ka precision kiʻekiʻe, ka hoʻolālā like, ka hana maikaʻi loa a me ke kumu kūʻai haʻahaʻa.
Kaʻina hana
Kaʻina hana: mea hoʻopili → hui ʻana → hoʻoheheʻe ʻia → hoʻoheheʻe ʻia → sintering → kaʻina hana hope.
ʻO ka pauka mineral
ʻO ka nui o ka nui o ka pauka metala i hoʻohana ʻia i ke kaʻina MIM he 0.5 ~ 20μm; ʻO ka manaʻo, ʻoi aku ka maikaʻi o nā ʻāpana, ʻoi aku ka nui o ka ʻili kikoʻī, e maʻalahi ai ke hoʻohālikelike a me ka sinter. Ke hoʻohana nei ke kaʻina hana metallurgy pauka i nā pauka coarser ʻoi aku ka nui ma mua o 40μm.
Pili kino
ʻO ka hana o ka mea hoʻopili organik ka mea e hoʻopaʻa ai i nā ʻāpana pauka metala i loaʻa ka rheology a me ka lubricity i ka hui ʻana i ka wā i wela ai i ka pahu o ka mīkini injection, ʻo ia hoʻi, he mea lawe ia e hoʻokele i ka pauda e kahe. No laila, koho ʻia ka mea paʻa e lawe i ka pauka holoʻokoʻa. No laila, ʻo ke koho ʻana i ka huki paʻa ʻo ia ke kī i ka hoʻoheheʻe ʻana i ka pauka holoʻokoʻa.
Nā mea e pono ai no nā mea hoʻopili organik:
1.ʻO ka hoʻohanaʻana i ka liʻiliʻi liʻiliʻi hiki ke hana i ka rheology maikaʻi o ka hui;
2. ʻAʻohe pane, ʻaʻohe hopena kemika me ka pauka metala i ka wā o ke kaʻina hana hoʻohemo;
3.Easy e wehe, ʻaʻohe kalapona i koe i loko o ka huahana.
Huihui
Hoʻohui like ʻia ka pauka metala a me ka mea hoʻopili organik e hana i nā ʻano mea maka i loko o kahi hui no ka hoʻoheheʻe ʻana. Hoʻopili pololei ka like ʻana o ka hui ʻana i kona wai, no laila e pili ana i nā ʻāpana kaʻina hana injection, a me ka density a me nā waiwai ʻē aʻe o ka mea hope. ʻO kēia ʻanuʻu o ke kaʻina hana hoʻoheheʻe i hoʻohālikelike ʻia me ke kaʻina hana hoʻoheheʻe plastic, a ʻo nā ʻano mea hana like nō hoʻi. I ka wā o ke kaʻina hana hoʻoheheʻe ʻia, ua wela ka mea i hui ʻia i loko o ka pahu o ka mīkini injection i loko o kahi mea plastik me nā waiwai rheological, a hoʻokomo ʻia i loko o ka mold ma lalo o ke kaomi injection kūpono e hana i kahi blank. Pono ke ʻano like ʻole o ka mea i hoʻoheheʻe ʻia i loko o ke kaʻina hana sintering.
Weheʻe
Pono e hoʻoneʻe ʻia ka mea hoʻopili organik i loko o ka blank i hoʻoheheʻe ʻia ma mua o ka sintering. Kapa ʻia kēia kaʻina hana he unuhi. Pono ke kaʻina hana unuhi e hoʻokuʻu mālie ʻia ka mea hoʻopili mai nā ʻāpana like ʻole o ka blank ma nā kahawai liʻiliʻi ma waena o nā ʻāpana me ka ʻole e hōʻemi i ka ikaika o ka blank. ʻO ka wikiwiki o ka wehe ʻana i ka mea hoʻopaʻa maʻamau e hahai i ka diffusion equation. Hiki i ka Sintering ke ho'ēmi a hoʻomāmā i ka porous degreased blank i nā huahana me kekahi ʻano a me nā waiwai. ʻOiai e pili ana ka hana o nā huahana i nā kumu kaʻina he nui ma mua o ka sintering, i nā manawa he nui, ʻo ke kaʻina hana sintering he hopena nui a hoʻoholo paha i ka hoʻolālā metallographic a me nā waiwai o ka huahana hope.
Mahope o ka hana ana
No nā ʻāpana me nā koi nui kikoʻī, pono ka hoʻoponopono hope. ʻO kēia kaʻina hana like me ke kaʻina hana wela o nā huahana metala maʻamau.
Kaʻina hana pono
Hoʻohana ʻo MIM i nā hiʻohiʻona o ka ʻenehana metallurgy pauka e hoʻoheheʻe i nā ʻāpana mechanical me ke kiʻekiʻe kiʻekiʻe, nā waiwai mechanical maikaʻi a me ka maikaʻi o ka ʻili; i ka manawa like, hoʻohana ia i nā hiʻohiʻona o ka hoʻoheheʻe ʻana i ka plastic injection e hana i nā ʻāpana me nā ʻano paʻakikī i ka nui a me ka maikaʻi.
1. Hiki ke hoʻokumu i nā ʻāpana me nā hale paʻakikī.
ʻO ka hana metala maʻamau ka hana ʻana i nā papa metala i huahana ma o ka hoʻohuli ʻana, ka wili ʻana, ka hoʻolālā ʻana, ka wili ʻana, ka ʻeli ʻana, ka ʻoluʻolu, a me nā mea ʻē aʻe. Hoʻohana ʻo MIM i kahi mīkini injection e hoʻokuʻu i ka huahana blank e hōʻoia i ka hoʻopiha piha ʻana o ka mea i ka lua mold, no laila e hōʻoiaʻiʻo ai i ka hoʻokō ʻana i ke ʻano paʻakikī o ka ʻāpana.
2. ʻO ka huahana he microstructure likeʻole, kiʻekiʻe kiʻekiʻe a me ka hana maikaʻi.
Ma lalo o nā kūlana maʻamau, hiki i ka nui o nā huahana paʻi ke piʻi i kahi kiʻekiʻe o 85% o ka nui theoretical density; ʻO ka nui o nā huahana i loaʻa e ka ʻenehana MIM hiki ke piʻi ma mua o 96%.
3.High maikaʻi, maʻalahi e hoʻokō i ka nuipa a me ka hana nui.
ʻO ke ʻano metala i hoʻohana ʻia i ka ʻenehana MIM he ola like ia me ka ʻenekinia i hoʻoheheʻe ʻia. Ma muli o ka hoʻohana ʻana i nā ʻāpana metala, kūpono ʻo MIM no ka hana nui o nā ʻāpana.
4.Wide ākea o nā mea kūpono a me nā kahua noi ākea.
Hiki i ka MIM ke hoʻohana i ka hapa nui o nā mea metala, a me ka noʻonoʻo ʻana i ka hoʻokele waiwai, ʻo nā mea noi nui e pili ana i ka hao, ka nickel-based, haʻahaʻa haʻahaʻa, keleawe, kiʻekiʻe-wikiwiki kila, stainless steel, gram valve alloy, cemented carbide, a me titanium-based metala.
5.Significantly mālama i nā mea maka
ʻO ka maʻamau, ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana o ka metala i ka hana metala. Hiki i ka MIM ke hoʻomaikaʻi maikaʻi i ka hoʻohana ʻana o nā mea maka, ʻo ia ka 100% hoʻohana.
6. Hoʻohana ke kaʻina MIM i ka pauka maikaʻi micron-level.
ʻAʻole hiki iā ia ke hoʻolōʻihi i ka sintering shrinkage, kōkua i ka hoʻomaikaʻi ʻana i nā waiwai mechanical o nā mea, hoʻonui i ke ola luhi o nā mea, akā hoʻomaikaʻi pū i ke kūʻē ʻana i ka corrosion stress a me nā waiwai magnetic.
Nā wahi noi
Hoʻohana nui ʻia kāna mau huahana i nā ʻoihana ʻenehana e like me ka ʻenehana ʻike uila, nā mea biomedical, nā lako keʻena, nā kaʻa, nā mīkini, nā lako, nā mea haʻuki, nā ʻoihana kiaʻi, nā mea kaua a me ka aerospace.
1. Nā kamepiula a me kā lākou mau mea kōkua: e like me nā ʻāpana paʻi paʻi, nā cores magnetic, nā pine striker, a me nā ʻāpana hoʻokele;
2. Nā mea hana: e like me nā ʻāpana drill, nā ʻoki ʻoki, nā nozzles, nā pū, nā mea ʻoki milling spiral, nā kuʻi, nā kumu, nā wrenches, nā mea uila, nā mea hana lima, etc.;
3. Nā mea hana hale: e like me nā pahu wati, nā kaulahao wati, nā pulupulu niho uila, nā ʻoki, nā pā, nā poʻo kolepa, nā loulou mea hoʻohana, nā wili peni, nā poʻo mea hana ʻoki a me nā ʻāpana ʻē aʻe;
4. Nā ʻāpana no nā mīkini lapaʻau: e like me nā papa orthodontic, ʻokiʻoki, a me nā tweezers;
5. ʻāpana koa: nā huelo missile, nā ʻāpana pū, nā poʻo kaua, nā uhi pauda, a me nā ʻāpana fuze;
6. Nā ʻāpana uila: ʻeke uila, nā kaʻa uila, nā ʻāpana uila, nā mea ʻike;
7. Nā ʻāpana mīkini: e like me nā mīkini hoʻokuʻu pulupulu, nā mīkini lole, nā mīkini ʻili, nā mīkini keʻena, a pēlā aku;
8. Nā ʻāpana kaʻa a me ka moana: e like me ke apo i loko, ka lima lima, ka lima hoʻolaha, ke alakaʻi valve, ka hui hoʻonohonoho ʻana, nā ʻāpana airbag, etc.
