Ke makemake nā ʻenekinia i nā ʻāpana metala kūpono e kū i ke koʻikoʻi, ka ʻino, a i ʻole nā ʻaʻahu abrasive - ʻoi aku ka nui o nā ʻōnaehana hydraulic, nā ʻaila a me nā ʻea, a i ʻole nā hui pauma hana kiʻekiʻe - ʻaʻole lākou e ʻimi wale i *kekahi * mea hoʻolako. Huli lākou i a hale hana hoʻoheheʻe metala mim me ka hoʻāʻo ʻia ʻana ma luna o nā kobalt-nickel superalloys, ka mana GD&T paʻa, a me ka ʻae ʻole ʻana no ka ʻano like ʻole o ka hui. ʻO ia ke kumu e huli nui ai nā OEM o ka honua a me nā mea hoʻolako Tier-1 iā Qingdao Qiangsenyuan Technology Co., Ltd.-ʻaʻole ma ke ʻano he kumu hana maʻamau, akā ma ke ʻano he hoa loea i hoʻokomo ʻia i ka loop design-to-delivery.
Eia ka mea i hoʻokaʻawale iā lākou: ʻaʻole lākou e mālama i ka MIM ma ke ʻano he kaʻina kūʻokoʻa. Hoʻohui lākou me ka naʻauao i loko o kahi kaiaola hana ʻoi aku ka pololei - kahi e hānai ai ka hoʻolele kālā ʻana i ka mīkini CNC, kahi e hoʻopili ai ka mālama wela me nā koi microstructure, a ma kahi o kēlā me kēia pahu pahu pahu pahu a AMS 5387 e lawe ai i ka traceability piha mai ka billet i hōʻoia ʻia i ka hōʻike CMM hope. Ua ʻike mākou i ka neʻe ʻana o nā mea kūʻai mai ka ʻimi ʻana ʻekolu (hale hoʻolālā → mea kūʻai MIM → hoʻopau) i kahi kuleana hoʻokahi-ʻoki ʻana i ka manawa alakaʻi e 37% a e hōʻemi ana i ka hana hou ʻana e 92% ma nā hale pahu piston pump cylinder.
ʻO ka hapa nui o nā hale hana MIM e hakakā me nā mea kiʻekiʻe-alloy. Cobalt-ma muli o T800? Nikela-chromium-molybdenum huila? ʻAʻole kēia he "mea ʻai ʻē aʻe." ʻOkoʻa ko lākou hōʻemi wela mai ka 316L stainless a hiki i ka 18%; ʻO kā lākou ʻaoʻao sintering e koi i ka mana kaomi ʻāpana oxygen; a hāʻule loa ko lākou machinability post-sinter inā hee ka ʻike kalapona ma mua o ± 0.02%. ʻAʻole hoʻopuka ʻo Qingdao Qiangsenyuan i ka hōʻoia metallurgical. Hoʻomohala pū kā lākou hui i nā kikoʻī meaʻai meaʻai me nā mea hoʻolako maka—a hōʻoia i kēlā me kēia ʻāpana komo e kūʻē i nā koi ASTM E1479 a me ISO 9001:2015 Annex B. I loko o kekahi papahana i hala iho nei, ua loaʻa iā lākou kahi pilikia hoʻokaʻawale carbide maʻalahi i ka pauka AMS 5387 ma mua o ka sintering ʻatikala mua - e mālama ana i kahi mea kūʻai aku $210,000 i nā mea hana i kālai ʻia a hoʻomaikaʻi hou.
ʻAʻole kūʻai ʻia ka hoʻohui kūʻokoʻa ma ʻaneʻi-ʻo ia ka hana maoli. ʻO kā lākou ISO-compliant hale nā laina MIM debinding a sintering ma ka ʻaoʻao o 5-axis CNC cell, vacuum heat treatment furnaces, a me nā keʻena nānā nānā ʻili. ʻAʻohe lima lima. ʻAʻohe hakahaka unuhi ʻikepili. Ke hoʻouna ka mea kūʻai i kiʻi kiʻi no ka huila winch center shaft maʻamau-me 0.015 mm cylindricity callout ma kahi 120 mm OD a me HRC 58–62 paʻakikī o ka ʻili, holo lākou i ka GD&T simulation *ma mua o * ka nānā ʻana i ke kahe kahe. Hāʻawi lākou i nā ʻoki ʻoki e pahele i ke koena mea hoʻopili. Hoʻoponopono lākou i ka wahi o ka ʻīpuka e hōʻemi i ka warpage ma ka 1.2-mika lōʻihi. A hāʻawi lākou i nā ʻatikala mua me nā hōʻike metrology holoʻokoʻa - ʻaʻole wale nā paʻi paʻi.
He aha ka manaʻo o nā luna kūʻai? ʻAʻole "ʻenehana papa honua." Manaʻo lākou i ka hiki ʻana o ke kino valve i ka papa manawa, e hui me ka ASME B16.34 kaomi hoʻāʻo ma 1.5 × helu ʻana i ke kaomi lawelawe, a hoʻokomo me ka ʻole o ka shimming. Hāʻawi ʻo Qingdao Qiangsenyuan i kēlā ʻoiaʻiʻo - ʻaʻole ma o nā ʻōlelo hoʻohiki, akā ma o ke aʻo ʻana i kākau ʻia: nā palapala hōʻoia i komo i ka manawa maoli, nā loiloi CMM i ka hana ma 3 mau kikowaena koʻikoʻi, ka hoʻāʻo hana hope loa ma nā pahu hoʻāʻo hydraulic calibrated, a me ka hiki ke ʻike piha ʻia i lalo i ka umu ahi batch ID a me ka helu ramp sintering. Kākoʻo kā lākou lean workflow i ka holo prototype o 50 mau ʻāpana a paʻa i ka hana medium-volume a hiki i 15,000 mau ʻāpana / makahiki-me ka ʻole o ka mōhai ʻana i nā hua mua.
Ke nānā nei i mua, ʻaʻole ʻo ka mea ʻokoʻa maoli ka mea nona ka mīkini MIM nui loa-akā ʻo wai ka mea e hoʻopili maikaʻi i ka ʻokoʻa ma waena o ka ʻepekema metallurgy pauka a me ka hilinaʻi i hoʻonohonoho ʻia. Ke hoʻonui nei ʻo Qingdao Qiangsenyuan i ka R&D i loko o nā kaʻina hana hoʻoheheʻe hybrid-MIM no nā ʻāpana ʻāpana nui a lahilahi; hoʻonui i nā palapala hōʻoia e hoʻokomo i ka API 6A a me NORSOK M-650; a me ke kūkulu ʻana i ka mana māhoe kikohoʻe no ka hoʻohālikelike ʻana i ka distortion sinter. No ka poʻe ʻenekinia e hōʻike ana i nā kiwi puʻe, nā kumu pahū, a i ʻole nā nozzles cobalt alloy - ʻaʻole kēia he mea ʻē aʻe. hale hana hoʻoheheʻe metala mim. ʻO ia ka hoa hana e mālama i ke ola lawelawe o kāu ʻāpana e like me kā lākou KPI ponoʻī.
