Ke hōʻike ʻia e nā ʻenekinia hale hana ʻāpana hoʻoheheʻe metala ʻAʻole kūʻai wale lākou i nā ʻāpana - ke hoʻopaʻa nei lākou i ke kūpaʻa dimensional ma lalo o 300 MPa koʻikoʻi, microstructural integrity ma hope o ka mālama ʻana i ka wela, a me ka neʻe ʻole ʻana o ka batch-to-batch ma AMS 5387 alloy hardness. ʻO ia ke kumu ʻaʻole ʻo ka pololei he koi kūʻai aku ma ʻaneʻi - ʻo ia ke koi kumu.
Ua ʻike mākou i ka nui o nā papahana e kū nei ma ke kahua prototype no ka mea ua mālama ka mea hoʻolako i koho ʻia iā MIM ma ke ʻano he "kaʻina pauka ʻē aʻe." I ka ʻoiaʻiʻo, ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka metala no nā ʻāpana ʻoihana koʻikoʻi ma mua o ka sintering i nā umu a me nā meaʻai. Pono ia i ka hoʻopaʻi metallurgical ma waena o ka loaʻa ʻana o nā mea waiwai, ka hoʻopaʻa ʻana i ka mana kinetics, nā ʻaoʻao sintering vacuum i hoʻopaʻa ʻia i kēlā me kēia ʻohana alloy-a me ka hoʻohui koʻikoʻi me ka hoʻopau ʻana o CNC a me ka nānā ʻana i ka GD&T. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ʻAʻole ma ke ʻano he hoʻolālā wale nō, akā ma ka hoʻolālā ʻana: ʻo kēlā me kēia MIM i loaʻa mai i ka puʻupuʻu puʻupuʻu puʻupuʻu, piston pump cylinder, a i ʻole winch center shaft roller e hoʻomaka ana me ka T800 kobalt-based raw material, ʻaʻole ka pauka kila stainless steel.
ʻEkolu mau mea ʻenehana i hoʻokaʻawale i ka mana maoli mai nā mea kūʻai aku katala:
- ʻAʻole hiki ke kūʻai ʻia ka traceability. Pono e lawe i ka palapala hoʻoheheʻe kobalt AMS 5387 hoʻokahi - ʻaʻole he hōʻike hoʻāʻo wili wale. Ke hōʻoia nei mākou i ka ʻike oxygen pauda komo mai (<0.025%), puunaue ka nui o ka pōpō (D50 = 8–12 µm), a me nā palena koena mea hoʻopili ma mua o ka hoʻouka ʻana i ka laina hui. ʻAʻohe ʻokoʻa.
- ʻAʻole kū kaʻawale ʻo MIM no nā ʻāpana hana. Ma kahi kokoke i 92% o kā mākou mau mea i hana ʻia e MIM e hana i ka mīkini lua-ʻoi loa no ka hoʻopaʻa ʻana i nā ʻili, nā ʻano milo, a me nā puke pai. ʻO kā mākou mea hoʻokō ISO e holo ana i nā kikowaena CNC multi-axis e pili pono ana i ka laina sintering, e hoʻopau ana i ka transit inter-facility e pilikia ai ka hoʻolaha ʻana o ka micro-crack i nā superalloys brittle.
- Hana ʻia ka mana nui ma mua o ka hoʻokuʻu ʻia ʻana—ʻaʻole ma hope. ʻAʻole hoʻohana ʻia ka uku hōʻemi ma ke ʻano he kumu pale. No ka hale cylinder 42-mm-diameter in T800 alloy, hoʻohālike mākou i nā hopena gradient thermal ma waena o ka lua mold, hoʻoponopono i nā gradients density ʻōmaʻomaʻo i loko o ka meaʻai, a hōʻoia i ka hoʻomanawanui hope me ka hoʻohana ʻana i nā mīkini ana coordinate i hoʻopaʻa ʻia i nā kūlana ISO 10360-2-ʻaʻole nā mea hoʻohālikelike optical.
Hiki i kekahi ke hoʻopaʻapaʻa e hāʻawi ana ka hoʻolei kālā kuʻuna i nā waiwai mechanical maikaʻi no nā ʻāpana kobalt ʻāpana mānoanoa. Akā, ʻokoʻa ka hōʻike ʻana o kā mākou ʻikepili: no ka mānoanoa o ka pā ma lalo o 12 mm, hāʻawi ka MIM i 15-18% kiʻekiʻe o ka ikaika tensile a me 22% hoʻomaikaʻi i ka pale ʻana i ka luhi ma AMS 5387-no ka mea, ua hoʻololi ka microstructure fine-grained like ʻole i nā hale dendritic cast. ʻO ke kālepa-off? ʻOi aku ka paʻakikī geometric. ʻAʻole mākou e ʻae i ka MIM no nā ʻāpana me nā hiʻohiʻona hiʻohiʻona ma luna o 8:1 a i ʻole nā hiʻohiʻona kūloko liʻiliʻi ma mua o Ø0.3 mm me ka ʻole o ka hana hou ʻana. ʻO kēlā ʻoiaʻiʻo e pale i ka hana hou ʻana ma hope.
He aha nā mea hoʻohana e nīnau maoli ai - a he aha nā mea e hoʻololi ai i nā hopena o ka papahana - ʻaʻole "Hiki iā ʻoe ke hana?" akā "Hiki iā ʻoe ke hoʻopaʻa i ka ± 0.015 mm ma kahi 120-mm cylindrical ʻili * ma hope o ka nitriding?" a i ʻole "E ola anei kāu ʻāpana T800 MIM i nā pōʻai he 10,000 ma 180°C i ka kahe aila waiwai nui o H₂S?" Kākoʻo mau ʻia kā mākou pane e nā hōʻike hoʻāʻo - ʻaʻole nā ʻōlelo hoʻohiki. Loaʻa i kēlā me kēia pūʻulu nā hiʻohiʻona tensile i hoʻāʻo ʻia no ka ASTM E8, ka palapala ʻāina paʻakikī ma nā ʻāpana koʻikoʻi, a me ka hōʻoia ʻana i ka paʻakai paʻakai no nā papa i hoʻopau ʻia. Mālama mākou i nā laʻana no 5 mau makahiki. Inā nīnau ka mea kūʻai aku i ka hana, huki mākou i ka hōʻike CMM kumu, ka log sintering, a me ka pale mālama wela—ua pili nā mea a pau i hoʻokahi helu serial.
ʻO kēlā kiʻekiʻe o ka hoʻohui kūʻokoʻa-kūpono waiwai, ka hana MIM, ka mīkini pololei, ka hoʻomaʻamaʻa wela, a me ka hoʻāʻo hana ma lalo o ka hale hoʻokahi - ʻo ia ka liʻiliʻi o nā lima lima, ʻoi aku ka wikiwiki o ka loiloi kumu kumu, a me ka ʻole ambiguity ke hāʻule kekahi mea ma waho o ka spec. ʻO ia hoʻi ka hopu ʻana i nā pilikia hana hana i ka wā mua: i ka hapaha hope, ua hōʻailona mākou i kahi kelepona GD&T i manaʻo i ka emi ʻana o ka isotropic i loko o kahi kino valve paʻakikī. Ua hoʻopakele ʻo Redesign i ka mea kūʻai aku i ʻekolu pule a me $27,000 i nā mea hana ʻatikala mua.
Ke nānā nei i mua, ʻo ka bottleneck maoli i ka MIM kiʻekiʻe-alloy ʻaʻole ia he mea lako-ʻo ia ka ʻike noi. Ke hoʻonui nei mākou i kā mākou manaʻo R&D i nā kaʻina hana hybrid: hoʻohui ʻana i nā ʻupena ʻupena MIM me nā pūpū o waho one-hoʻolei pololei ʻana no nā kumu pāpaʻi nui-diameter, a laila e hoʻohana wale i nā pilina hana. Hoʻokiʻoki kēia i ke kaumaha ma 31%, hoʻomaikaʻi i ka hāʻawi ʻana i ka wela wela, a mālama i ka pale ʻana i ka corrosion piha i kahi mea nui loa.
Inā pili kāu kauoha aʻe i nā ʻāpana MIM cobalt-nickel no nā ʻōnaehana hydraulic, ʻaila a me nā mea hana lawelawe kinoea, a i ʻole nā hui winch kaʻa ʻenekinia - a pono ʻoe i ka palapala e hoʻihoʻi hou ʻia, ʻaʻole i ʻōlelo ʻia i ka ʻae ʻana - a laila e hōʻoia i ka mana o ke kaʻina MIM maoli o ka mea hoʻolako ma mua o kā lākou hae pūnaewele. E noi i kā lākou AMS 5387 sintering log. E noi i kā lākou hōʻike CMM ma kahi pūʻulu nozzle T800 hou. E hōʻoia inā ʻo kā lākou "metal injection molding parts factory" e lawelawe i ka palapala hōʻoia i loko o ka hale a i waho paha. Na nā pane e haʻi iā ʻoe i nā mea āpau.
