Ke ʻimi nā ʻenekinia a me nā luna kūʻai i kahi hale hana hoʻoheheʻe metala, ʻaʻole lākou e ʻimi wale ana i ka hiki—ke ʻimi nei lākou i ka hilinaʻi dimensional, ka paʻa pono o nā mea, a me ka hana i hōʻoia ʻia i nā noi koʻikoʻi. Eia naʻe ka mea a ka poʻe i ʻike lohi loa: ʻo ka hapa nui o nā hale kūʻai "MIM-hiki" ke mālama wale i nā geometries maʻalahi ma 316L a i ʻole 17-4PH. He kakaikahi wale no ka hana pono ana i na kobalt-nickel superalloys, malama i ka traceability piha ma na puu wela, a i ole e hoohui i ka hoolei ana me ka pololei CNC hoopau—ma lalo o ka hale hookahi.
No ke aha e kuhikuhi ai ke koho mea waiwai i kāu hoa MIM—ʻaʻole hiki ke hana wale
Ua ʻike mākou i ka hoʻi ʻana o nā mea kūʻai aku i ʻekolu manawa i ke kiʻi like: ʻo ka mua no ka porosity i nā hale pahū AMS 5387, ka lua no ka microcracking ma hope o ka mālama ʻana i ka wela, ʻekolu no ka GD&T nonconformance ma nā pilina noho valve. Hoʻihoʻi ʻia kēlā me kēia hemahema i hoʻokahi kumu kumu - ʻaʻole maikaʻi nā mea hana, akā ʻaʻole lawa ka mana metallurgical i luna. Hoʻomaka ka maikaʻi MIM ʻoiaʻiʻo ma mua o ka hoʻokuʻu ʻia ʻana: hoʻopaʻa ʻia i ka pauka maka, ka hoʻopaʻa ʻana i ka oxygen, sintering vacuum me nā kiʻi kikoʻī / soak, a me ka HIP post-sinter inā pono.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. E hana ana i kahi keʻena kūpono ISO kahi e loaʻa ai i kēlā me kēia pahu kobalt alloy - mai T800-based nozzles a hiki i ka AMS 5387 piston pump parts - e komo ana i ka nānā ʻana o ka pauka (O / N / H content, particle size distribution), green part density verification, and sintered density confirmation by Archimedes method. ʻAʻohe manaʻo. ʻAʻohe waivers hui. ʻAʻole kēia he hale kiʻiʻoniʻoni hoʻokō-ʻo ia ke ʻano e pale aku ai ʻoe i ka ʻokoʻa shrinkage 12% i loko o kahi pahu hoʻomanawanui 0.05 mm.
Hoʻohui Kūʻokoʻa e hāʻawi maoli i ke kūpaʻa-ʻaʻole wale i nā koi kūʻai
ʻO kekahi mau mea hoʻolako i waho o ka sintering. ʻO nā mea ʻē aʻe e mahiʻai i ka mīkini hope. Hoʻopau kēlā ʻāpana i ka hana hou ʻana. Ua ana mākou i nā hewa hōʻuluʻulu kumulative ma mua o ± 0.08 mm ma waena o ʻekolu mau mea kūʻai aku e lawelawe ana i hoʻokahi ʻāpana: hoʻolei → sintering → wili → hōʻoia CMM.
Ma QINGDAO QIANGSENYUAN, hoʻolei kālā, MIM, CNC machining, a me ka hoʻopau ʻana i ka ʻili i loko o kahi kaiapuni i hoʻomalu ʻia. Ke neʻe nei ke kino valve kaomi mai ka hoʻomākaukau ʻana i ka meaʻai a hiki i ka passivation hope me ka ʻole o ka hele ʻana i kahi uapo moku. ʻO ia hoʻi, ʻoi aku ka paʻakikī o ka hoʻomalu ʻana i ka moʻolelo wela, nā puka puka manaʻo CMM i loko o ke kaʻina, a me nā micro-scratches i hoʻohana hou ʻia i ka hoʻihoʻi hou ʻana ma nā ʻili. ʻO kā lākou mīkini pūnaewele CNC multi-axis i hoʻokaʻawale pololei ʻia i nā hiʻohiʻona kokoke i ka ʻupena - ʻaʻohe mea hoʻohui lua-a hoʻohana i ka mālama wela kūloko wale nō kahi mea nui loa ke kū'ē i ka luhi.
Hāʻawi kēia hoʻohui ʻana i nā hopena maoli: 92% ka helu o ka ʻatikala mua ma nā hiʻohiʻona koʻikoʻi GD&T; paʻa paʻa ʻo Rockwell C58–62 ma waena o nā huila lāʻau T800; a hiki ke hoʻopau ʻia ka ʻili i ka Ra 0.4 µm ma nā ala kahe o ka cobalt alloy—hōʻoia me ka optical profileometry, ʻaʻole ka hoʻohālikelike ʻike.
Kahi i hāʻule ai ka hapa nui o nā hale hana MIM—a pehea e hoʻoponopono ai ka hui ʻenehana
"Hiki iā ʻoe ke hana i kēia?" ʻo ia ka nīnau mua hewa. ʻO ka mea kūpono: "He aha ka hana a kēia ʻāpana * hana i ka hana pae ʻōnaehana?" ʻAʻole ʻo ka huila winch center shaft ʻaʻole ia he puʻupuʻu kaʻa wale nō - he mea hoʻokele haʻahaʻa kaʻa kaʻa i waena o ka hoʻouka haʻalulu a me ka ʻike wai paʻakai. Pono kona geometry e kaulike i ke koʻikoʻi koʻikoʻi, ka paʻa ʻana o ka lubricant, a me ka pale ʻana i ka corrosion.
Hoʻokomo ʻo QINGDAO QIANGSENYUAN i ka loiloi ʻenehana * ma mua o ka hoʻomaka ʻana o ka mea hana. Hoʻomaka koke ka hae o kā lākou hui: nā hoʻololi ʻana o ka mānoanoa o ka pā e kono ana i ka warpage, nā ʻokiʻoki e koi ana i nā electrodes EDM kumukūʻai, a i ʻole nā radii paʻa loa no ka kahe ʻana o ka pauka i ka wā o ka injection. ʻAʻole lākou e ʻōlelo wale "ʻae" - hāʻawi lākou i nā mea ʻē aʻe i kākoʻo ʻia e ka FEA-validated sintering simulations. Ua ho'emi 'o OEM i ka manawa alaka'i prototype e 40% ma hope o ka ho'ololi 'ana mai ka "design-for-machining" i ka ho'omohala pū 'ana i ka geometry me ka MIM-friendly.
Mālama pū lākou i nā hui ʻenehana me nā mea hoʻolako mea i hōʻoia ʻia - ʻaʻole wale no ka pepa, akā no nā loiloi metallurgical hui. I ka wā i ʻōlelo ai ka mea kūʻai aku i ka AMS 5387 me ka ≤12 ppm sulfur no ka hoʻomaikaʻi ʻana i ke kūpaʻa wela wela, ua hoʻonohonoho ʻo QINGDAO QIANGSENYUAN i ka hoʻāʻo ʻana i ka hoʻomaʻamaʻa ʻike maka me ka lab o ka mea hoʻolako - a laila hōʻoia i ka ʻāpana hope loa ma o OES spectroscopy ma kēlā me kēia ʻāpana.
Ke koho ʻana i kāu hale hana hoʻoheheʻe metala—E nānā i nā palapala hōʻoia i hala, e nānā i nā hiki
Hōʻike ʻo ISO 9001 iā ʻoe i kahi hale kūʻai he * ʻōnaehana maikaʻi. ʻAʻole ia e haʻi iā ʻoe inā hiki i kā lākou mea hoʻohana ke hoʻopaʻa i ka ± 0.015 mm ma kahi hale 120 mm cobalt alloy me ʻeono mau lua e hui pū ana. E nīnau mai:
- Ke hana nei ʻoe i ka nānā ʻana i ke kaʻina hana ma kēlā me kēia ʻāpana sintered - ʻaʻole wale ka ʻatikala mua?
- Hiki iā ʻoe ke hāʻawi i ka traceability piha mai ka palapala pauka a hiki i ka ʻāpana ʻāpana ID, me ka hoʻopili ʻana i nā log pōʻai?
- He aha kāu hana hana lōʻihi loa ma AMS 5387 a i ʻole T800—a he aha ka CpK no nā anawaena koʻikoʻi ma luna o kēlā holo?
- Hana pololei ʻoe i nā ʻāpana sintered-a i ʻole e hoʻopaʻa hou i kahi laina CNC ʻokoʻa?
Kūlike ʻo QINGDAO QIANGSENYUAN TECHNOLOGY i kēlā me kēia—ʻaʻole ma ke ʻano he ʻokoʻa, akā ma ke ʻano he hana maʻamau. He haiki ko lākou manaʻo: nā ʻāpana metala pololei kahi i koho ʻole ʻia ai ka hāʻule ʻole - nā ʻili wai wai, nā hale pāpaʻi, nā mea hana o waho. ʻAʻole lākou e alualu i ka leo. Hoʻokumu lākou i ka repeatability.
No nā ʻenekinia e hōʻike ana i nā ʻāpana ma lalo o >300 bar pressure, i nā mahana ma mua o 450°C, a i ʻole i ʻike ʻia i ka slurry abrasive—kou hale hana hoʻoheheʻe metala pono e hana ma mua o ka inject metala pauda. Pono ia e hōʻoiaʻiʻo i ka hoʻolālā, kūpaʻa, a me ka hana pae ʻōnaehana. ʻAʻole ʻike ʻia kēlā ma nā palapala. Ua hōʻoia ʻia i loko o kēlā me kēia nozzle cobalt sintered, kēlā me kēia hale piston mīkini, kēlā me kēia pahu winch i hāʻawi ʻia-i ka manawa, i ka kikoʻī, me ka ʻike piha.
