Ke ʻimi nei i a nalo ka wax casting kokoke ia'u hale hana? ʻAʻole ʻoe e ʻimi nei i kahi kokoke-pono ʻoe i ke kūpaʻa dimensional, ka kūlike metala, a me ka hoʻomanawanui ʻole no nā hemahema microstructural i nā ʻāpana koʻikoʻi. Ua ʻike mākou i ka nui o nā mea ʻenekinia e hoʻoholo no ka "kokoke" wale nō e kū i nā hemahema o ke kahua ma nā manifold hydraulic, nā hale pahū, a i ʻole nā nozzles cobalt-alloy ma lalo o 300+ bar cycling. Hoʻomaka ka hana honua maoli ma mua o ka ninini mua ʻana—a pau wale ma hope o ka hiki ke ʻike piha ʻia, ka hoʻokō GD&T i hōʻoia ʻia e CMM, a me ka hōʻoia hana.
No ke aha ʻaʻole lawa ka "kokoke iaʻu" - ʻoi loa no ka hoʻolei kālā
Hoʻihoʻi mai ʻo "Lost Wax Casting ma kahi oʻu hale hana" i nā haneli o nā papa inoa. ʻAʻole liʻiliʻi ke ʻano o ka palapala honua inā nele ka hale kūʻai i ka AMS 5387 kobalt alloy hoʻohana ʻana, ʻaʻole hiki ke hoʻopaʻa i ± 0.02 mm ma nā ʻūhā turbine pā lahilahi, a i ʻole nā mea hoʻomaʻamaʻa wela i waho me ka ʻole o ka palapala hōʻoia. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mālama mākou i kēlā me kēia hoʻolei ʻana ma ke ʻano he mea koʻikoʻi-ʻaʻole no ka mea i kapa ʻia ʻo ia ʻano, akā no ka hāʻule ʻana o nā hale pahu piston pump cylinder ma mua o nā mea hoʻonaninani keleawe. Hoʻokahi mea kūʻai i hoʻouna aku i kahi kino valve prototype i ʻekolu mea hoʻolako: ʻelua mau ʻāpana i hāʻawi ʻia me nā puʻupuʻu porosity i nā fillets-concentrated; ua hana kekahi i ka radiographed piha, solution-annealed, a passivated unit i hala i 10,000-cycle pressure ho'āʻo ma ka holo mua.
ʻO ka ʻokoʻa? Hoʻohui kū pololei. Hoʻomalu mākou i ka hoʻoheheʻe ʻana i ke ʻano wax, nā pōʻai hoʻomaloʻo ʻana i ka pūpū seramika, ka dewaxing i kōkua ʻia i ka ʻawa, ka nui o ka umu ahi, ka hoʻoponopono ʻana i ka mīkini ma hope o ka hoʻolei ʻana—a me kēlā me kēia wahi nānā ma waena. ʻAʻohe lima lima. ʻAʻohe manaʻo. Hoʻopaʻa wale ʻia nā ʻaoʻao wela, nā palapala hōʻoia T800 i hoʻopaʻa ʻia, a me nā ana ʻike i hoʻopaʻa ʻia e pili ana i kāu faila STEP kumu—ʻaʻole he paʻi wale nō.
Kahi e kū ai ka hoʻolei pololei ʻana i nā koi ʻoihana maoli
ʻAʻole wehewehe ʻia kā mākou hana ma ke kaʻina hana - ua wehewehe ʻia e ka hana. ʻAʻole manaʻo nā puʻu kaomi i ka palapala ISO 9001 o kāu foundry. Manaʻo lākou inā paʻa ka pae o ka noho i ka Ra ≤ 0.4 µm ma hope o ka nitriding. ʻAʻole nīnau nā ʻōwili pahu waena Winch i ka nui o nā koʻi i loaʻa i kāu CNC—ke koi lākou i ka ʻoʻoleʻa torsional i loko o ± 0.05° ma luna o 12,000 rpm. ʻO ia ke kumu i kālele wale ʻia ai kā mākou kōpili koʻikoʻi i nā ʻāpana ʻehā: ʻāpana mīkini CNC, nā ʻāpana kobalt-nickel alloy, ka hao hao, a me nā hoʻoheheʻe kila kuhili ʻole-nā mea a pau i hana ʻia no nā ʻōnaehana hydraulic, nā mea hana ʻaila a me nā kinoea, nā kaʻa kaʻa ʻenekinia, a me nā hui pamu kūikawā.
Ma keʻano kiko'ī, hana mākou:
- ʻO AMS 5387 kobalt alloy 6 mau ʻāpana pāpaʻi—me nā hubs impeller me nā ʻāpana pā 0.8 mm a me nā ala hoʻomaha hoʻohui.
- ʻO nā nozzles kobalt alloy i helu ʻia no 650°C ka lawelawe mau ʻana i nā ʻōnaehana wela
- Piston pump cylinder hale me nā ala kahe kūloko i mīkini ʻia i ± 0.015 mm kūlana ʻoiaʻiʻo
- ʻO nā ʻāpana T800 maʻamau ʻole kahi e pono ai ka ikaika tensile ma mua o 1,380 MPa *ma hope o ka ʻelemakule hope loa.
Hōʻole mākou i nā "papa palapala hoʻohui hui." Akā, hōʻoia mākou i kēlā me kēia billet maka e kūʻē i ka ASTM E1479 chemical spectroscopy, hōʻoia i ke ʻano o ka palaoa ma o ka metallography pre- and post-heat-treat, a hoʻopili i nā heluhelu paʻakikī ma waena o nā ʻāpana keʻa-ʻaʻole wale nā kikoʻī.
ʻAʻohe ʻae i ka Traceability—a i ʻole Transparency
Hāʻawi kekahi mau hale kūʻai iā ʻoe i kahi hōʻike hoʻāʻo wili. Hāʻawi mākou iā ʻoe i kahi lola kikohoʻe piha: helu wela waiwai → ID cavity pattern wax → lot mold shell → log thermocouple furnace → CNC tool path timestamp → CMM hōʻike me nā uhi hoʻoneʻe ʻana i ka palapala kala. Lawe ʻia kēlā me kēia mea koʻikoʻi i kahi QR code e pili ana i kona mōʻaukala holoʻokoʻa-ʻaʻohe mea hoʻopili PDF, ʻaʻohe nānā lima.
ʻAʻole kēia he bureaucracy. ʻO ka hoʻohaʻahaʻa pilikia. I ka ʻike ʻana o kahi OEM ʻEulopa i nā microcracks ma 3% o kā lākou pahu cobalt plug, ua ʻae kā mākou traceability iā mākou e hoʻokaʻawale i ka pilikia i kahi ʻāpana umu dewaxing hoʻokahi-a hōʻoia i ka hoʻihoʻi ʻole ʻana i nā ʻāpana he 12 e hiki mai ana. I kēia manawa, ʻaʻole hiki i ʻelua mau mea kūʻai aku ke hoʻomaopopo i ka holo ʻana o ka umu ahi, ka mea hoʻololi o ka mea hoʻohana, a i ʻole ka hui mea hoʻolako alloy i komo.
ʻAʻole mākou e hūnā ma hope o ka hoʻomanawanui ʻana o ka "ʻoihana maʻamau". Inā hōʻike kāu kaha kiʻi i nā kāhea GD&T no ka datum B i kuhikuhi ʻia i kahi ʻili flange mīkini, nānā mākou *i kēlā ʻili*—ʻaʻole wale i ka ʻaoʻao o waho o ka hoʻolei ʻana. A hōʻailona mākou i nā pilikia hana hana * ma mua o ka hoʻomaka ʻana o ka mea hana: "ʻO kēia radius 0.3 mm ma ka hui ʻana o kāu awa kūloko a me ka lua nui e paʻa i ke koena seramika ke ʻole mākou e hoʻololi i ka hoʻolālā gating." ʻAʻole "E ho'āʻo mākou." ʻAʻole "Hiki paha ia." ʻO nā ʻoiaʻiʻo wale nō—i kākoʻo ʻia e ka simulation a me nā hana i hala.
Hoʻomaka kāu ʻanuʻu aʻe me kahi kaha kiʻi i hōʻoia ʻia—ʻaʻole kahi faila ZIP
Mai hoʻouna mai iā mākou i kahi sketch a manaʻo i kahi ʻōlelo. E hoʻouna mai iā mākou i kāu faila STEP i hōʻike ʻia e GD&T, nā kikoʻī waiwai, a me nā pae hoʻoholo hana—a e hoʻihoʻi mākou i kahi loiloi hana hana i loko o 48 mau hola. E haʻi mākou iā ʻoe i kahi e kūʻē ai nā kihi kikoʻī me kāu mau koi sila. Ma kahi o ka hoʻokomo ʻia ʻana o ke one i helu ʻia ma nā hoʻololi mānoanoa a lahilahi. Hiki ke hoʻokō ʻia kāu hoʻopau ʻana i ka ʻili ma hope * ma hope o ka hoʻolei kālā—a i ʻole koi i ka electropolishing lua.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. e hana ana mai kahi keʻena hoʻokō ISO ma Qingdao—akā "kokoke iaʻu" ʻaʻole ia he "hale kūʻai kūloko." ʻO ia ke ʻano o ka pane ʻenekinia kūloko, ke kuleana pilikia kūloko, a me ke kuleana kūloko no kēlā me kēia micron o ka ʻoiaʻiʻo dimensional. Hāʻawi mākou i nā mea kūʻai aku ma ʻAmelika ʻĀkau, ʻEulopa, a me Asia Hema—ʻaʻole ma o nā mea hoʻolaha, akā ma o ke kamaʻilio ʻenehana pololei. No ka mea, ʻaʻole pili ka hoʻolei pololei ʻana i ka honua. E pili ana i ke kuleana like ʻole no ka mea e piʻi ai ke kaomi, piʻi ka wela, a ʻaʻole he koho.
Inā makemake ʻoe i kahi nalo ka wax casting kokoke ia'u hale hana e mālama ana i kāu ʻāpana e like me ka mana o ka ʻōnaehana hoʻomalu i lalo o ka moana—hoʻomaka me ka hōʻoia, ʻaʻole kahi.
