Ke hōʻike ʻia e nā ʻenekinia hale hana hoolei pūpū nā lawelawe no nā ʻāpana metala kūpaʻa kiʻekiʻe, ʻaʻole lākou e kūʻai wale i kahi kaʻina hana - ke hoʻopaʻa nei lākou i ka hoʻihoʻi hou ʻana, ka mana microstructural, a me ka hilinaʻi hana ma lalo o ke kaomi. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ua hoʻolei mākou ma luna o 12,000 mau hale pahū kobalt-alloy mai ka makahiki 2019-e paʻa ana kēlā me kēia ± 0.05 mm GD&T i nā mahana lawelawe 800 ° C. ʻAʻole ia ka mana theoretical. ʻO ia ka mea e hana ʻia inā ʻaʻole mālama ʻia ka hoʻoheheʻe ʻia ʻana o ka pūpū ma ke ʻano he kaʻina kūʻokoʻa-akā ʻo ia ka hana mua i loko o kahi kaʻina hana hoʻoheheʻe-machining-wela i hui pū ʻia.
No ke aha e hāʻawi ai ʻo Shell Molding i kahi e hāʻule pōkole ai ʻo Sand Casting
ʻAʻole "ʻano hoʻolei ʻē aʻe wale nō ka hoʻoheheʻe ʻana." ʻO ia wale nō ke kaʻina hana kokoke i ka ʻupena e hāʻawi mau ana i ka hoʻopau ʻana o ka ʻili ma lalo o Ra 3.2 µm *a me* kūlike metala ma waena o nā ʻāpana pā lahilahi ma lalo o 6 mm. ʻIke mākou i kēia i kēlā me kēia lā: kahi kino valve hydraulic me 3.8 mm ka mānoanoa o ka paia, 12 mau kahawai hoʻomaha i loko, a me AMS 5387 cobalt alloy chemistry. ʻAʻole hiki ke hoʻolei ʻia ke one ma ʻaneʻi—ʻaʻole ma ke kumukūʻai, akā no ka pilikia o ka hoʻokomo ʻana i ka oxide a me ka hoʻololi kumu i ka wā o ka ninini ʻana. Hoʻoholo ka hoʻoheheʻe ʻia ʻana o ka shell i nā mea ʻelua. Hoʻopaʻa paʻa ka phenolic resin i hoʻopaʻa ʻia i ke one silica ma 230°C, paʻa i ka geometry a hiki i 1,420°C e ninini i nā mahana, a puhi ʻia me ka maʻemaʻe-ʻaʻohe koena koena i nā ala kahe koʻikoʻi.
Ua ana mākou iā ia: hōʻike ʻia nā ʻāpana huila T800 i hoʻoheheʻe ʻia i ka pūpū i ka 22% haʻahaʻa haʻahaʻa ma mua o nā one-cast lots—hōʻoia ʻia e ka ʻimi ʻana CT ʻoihana ma mua o ka hana ʻana. ʻO ia ka unuhi pololei i ke ola luhi. Ua hoʻolōʻihi aku kekahi mea kūʻai lako ʻaila o ʻAmelika ʻĀkau i nā manawa lawelawe hale pahū mai 4,200 a 7,800 mau hola hana ma hope o ka hoʻololi ʻana i kā mākou hale pahu pahu i hoʻoheheʻe ʻia. ʻAʻohe hoʻololi hoʻolālā. He mea hoʻomaka wale nō.
ʻAʻole he huaʻōlelo ʻo Vertical Integration—ʻO kāu hoʻēmi pilikia
Hāʻawi kekahi mau mea hoʻolako i nā mea hoʻoheheʻe ʻia i ka pūpū i nā mīkini ʻaoʻao ʻekolu. ʻAʻole mākou. Ke neʻe nei kēlā me kēia ʻāpana kobalt-nickel mai kā mākou ISO 9001-certified shell molding line i loko o kā mākou 5-axis CNC cell—ʻaʻohe logistic waho, ʻaʻohe paʻa paʻa paʻa ʻole, ʻaʻohe hui like ʻole o ka mōʻaukala wela. He mea nui ka hoʻomau ʻana ma nā ʻāpana e like me nā wili pahu piston pump center shaft rollers: paʻakikī iā HRC 58–62 *ma hope o ka hana ʻana, ʻaʻole ma mua. Inā hoʻomaʻamaʻa ʻia ka wela ma mua o ka mīkini ʻana, e hoʻoneʻe ʻia ke koena koʻikoʻi i ka 0.015 mm ʻoiaʻiʻo ke kūpaʻa kūlana ma ka puke pai. ʻAʻole loa kā mākou kaʻina hana.
Mālama mākou i kēlā me kēia ʻāpana: nā hōʻike hoʻāʻo ʻana i ka mīkini maka, nā lāʻau hoʻōla hoʻōla ʻana i ka pūpū, nā ʻōpala wela, nā hopena nānā ultrasonic post-cast, a me nā hōʻike CMM hope loa - ua hoʻopili ʻia i hoʻokahi dashboard traceability. I ka noi ʻana o kahi OEM ʻEulopa no ka moʻopuna waiwai piha ma kahi kauoha nozzle AMS 5387, ua hāʻawi mākou i 17 mau palapala i kau inoa ʻia i loko o 48 mau hola. ʻAʻole no ka hoʻopaʻa ʻana i nā pepa - akā no ka holo ʻana o ka ʻikepili mai ka sensor i ka ʻōnaehana i ka manawa maoli.
Nā palena o ka honua maoli—a pehea mākou e hana ai i loko o ia mau mea
He mau palena ko ka hoʻoheheʻe ʻana i ka pūpū. Paʻakikī ia me nā ʻāpana ma luna o 50 kg a i ʻole nā geometries e koi ana i nā undercuts hohonu ma mua o 15 ° me ka ʻole o nā cores collapsible. Hiki i kekahi ke hoʻopaʻapaʻa ʻoi aku ka maikaʻi o ka hoʻolei kālā ʻana. Akā, ʻaʻole hiki ke hoʻohālikelike ʻia ka hoʻolele kālā ʻana i kā mākou hoʻoili ʻana ma nā holo waena (50-500 pcs / mahina) o nā hoʻoheheʻe kila paʻakikī - ʻoi aku ka nui o ka wā e pono ai nā mea kūʻai aku i ka hoʻāʻo hana ma nā ʻāpana 3 mua. ʻO kā mākou laina hoʻoheheʻe ʻia e holo i 22 mau hola / lā, hoʻololi i nā mea hana ma lalo o 18 mau minuke, a hōʻoia i ka geometry cavity me ka nānā ʻana i ka laser ma mua o ka ninini mua ʻana.
Ke pale nei mākou i nā pilikia maʻamau: me ka hoʻohana ʻana i ke one i hoʻohana hou ʻia i loko o ka hui pū ʻana (ke kumu mākou i ka silica fused hou), e hoʻokuʻu i ka wela ma mua o ka hoʻolei hao nui (e hoʻolei mākou i ka wela o ka umu ma 45 ° C / hola e pale ai i ka haʻalulu wela), a i ʻole ke hoʻokuʻu ʻana i ka hoʻomaha ʻana ma hope o ka hoʻoiho ʻana i nā hale stainless (paʻa mākou ma 620 ° C no 4 mau hola, a laila hoʻomaha ka ea). ʻAʻole kēia "nā hana maikaʻi loa." He mau ʻanuʻu hiki ʻole ke kūkākūkā ʻia i kā mākou ʻōlelo aʻo hana-no ka mea ua ʻike mākou i ka puka ʻana o nā māwae i ka wā e lele ʻia ai kekahi.
ʻO ka mea āu e loaʻa maoli ai - ʻaʻole ka mea i hoʻohiki ʻia ma kahi palapala
Loaʻa iā ʻoe ke kūpaʻa dimensional: nā mea hoʻoheheʻe kila i kālai ʻia i ka ± 0.12 mm ma nā hiʻohiʻona a hiki i 320 mm ka lōʻihi, i hōʻoia ʻia me Zeiss CONTURA G2 CMM i calibrated i kēlā me kēia pule. Loaʻa iā ʻoe ka wānana metallurgical: i hoʻāʻo ʻia kēlā me kēia pūʻulu huila T800 no ka cobalt, chromium, tungsten, a me ka maʻi kalapona—ma loko o ± 0.03% o spec-me ka hoʻohana ʻana i ka spectrometry OES. Loaʻa iā ʻoe ke aʻo ʻana: 94.7% ka nui o ka manawa no nā kauoha prototype, 98.2% no ka hoʻokuʻu ʻana—mālama ʻia ma o nā dashboards ERP ola i kaʻana like me nā mea kūʻai.
A loaʻa iā ʻoe ka hui ʻenekinia—ʻaʻole ʻōlelo. I ka wā i hoʻouna mai ai kahi mea hana pahū ma ʻAsia Hema i kahi kiʻi kiʻi me ka 0.005 mm kelepona palahalaha ma kahi 280 mm × 180 mm e kau ana, ʻaʻole mākou i ʻōlelo "ʻae" a i ʻole "ʻaʻole." Ua holo mākou i ka hoʻohālike hoʻoheheʻe wela, ua hoʻololi mākou i ka hoʻonohonoho ʻana i ka puka makani, a ua manaʻo mākou e hana i ka flange *ma hope o ka hoʻomaha ʻana i ke kaumaha—ʻaʻole ma mua. Ka hopena? Ua lele ka helu o ka ʻatikala mua mai 62% a i 99%. ʻO ia ka ʻokoʻa ma waena o kahi mea kūʻai aku a me kahi hoʻonui ʻenehana o kāu hui.
Inā makemake ʻoe i kahi hale hana hoolei pūpū e mālama i ka pololei e like me ka physics-ʻaʻole ke kūʻai aku-ua mākaukau mākou e holo i kāu ʻāpana aʻe. ʻAʻole me nā ʻōlelo hoʻohiki. Me nā pepa kaʻina hana, nā hōʻike nānā, a me nā ʻikepili dimensional mai ka ʻāpana mua.
