Ke hōʻike nei nā mea ʻenekinia i ke kila kila no nā ʻāpana koʻikoʻi a me nā ʻāpana koʻikoʻi-e noʻonoʻo i nā kīwī kaomi i loko o nā ʻōnaehana hydraulic a i ʻole nā hale cylinder piston pump - pono lākou ma mua o ka pale ʻana i ka corrosion. Pono lākou i ke kūpaʻa dimensional ma lalo o ka paikikala wela, ka microstructural integrity ma hope o ka sintering, a me ka hoʻopau ʻana i ka ʻili e ola ana i ka media kahe abrasive. Ma laila kahi i hoʻolaʻa ʻia hale hana kila kuhiliʻole lilo i mea kūʻai ʻole-ʻaʻole ma ke ʻano he mea hoʻolako, akā ma ke ʻano he hoa hana.
No ke aha e koi aku ai ʻo MIM Stainless Steel i ka hoʻohui ʻana i ka Vertical Integration—ʻAʻole i ka lako wale nō
Ua ʻike mākou i nā papahana he nui e kū nei ma ke kahua prototype no ka mea ua lawelawe ka hale kūʻai MIM i ka hui ʻana a me ka hoʻopaʻa ʻana i nā meaʻai, akā ua hoʻokuʻu ʻia i waho i kahi mea hoʻohana umu ahi. ʻO nā māka kila kila ʻole e like me 17-4 PH a i ʻole 316L ke ʻano me ka manaʻo ʻole me ka ʻole o ka mana paʻa ma luna o ke kaomi ʻāpana o ka oxygen, nā ramp rate, a me nā manawa paʻa i ka wā sintering. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ka MIM holoʻokoʻa holoʻokoʻa-mai ka feedstock formulation me ka hōʻoia stainless steel pauka (ASTM A985-compliant), ma o solvent a me ka thermal debinding, i vacuum-sintering i ISO 9001-hōʻoia i nā kapuahi-i hoʻokō 'ia ma lalo o hoʻokahi hale. ʻAʻohe lima lima. ʻAʻohe ʻano like ʻole o ka ulu ʻana o ka palaoa. ʻAʻohe mea kupanaha ke koi ʻia nā kelepona GD&T i ± 0.02 mm ma nā hiʻohiʻona pā lahilahi ma lalo o 1.2 mm mānoanoa.
He mea nui kēia hoʻohui ʻana i ka wā e hui ai ke geometry i ka hana. Pono ka pa'akikī ≥38 HRC *a me* ka oolea o ka ili o Ra ≤0.8 µm—koi e koi ai i ke kuai ana ma waena o ka mīkini sintering a me ka mīkini post-MIM. Hoʻopili kā mākou hale hana i kahi ākea: hoʻopili mākou i kahi ʻano ʻupena, a laila hoʻopili i ka multi-axis CNC hoʻopau me ka hoʻomaʻamaʻa wela hoʻohui ʻia - ʻaʻohe logistic waho, ʻaʻohe hoʻoponopono hou ʻana, ʻaʻohe nalowale o ka hoʻomau ʻana o ka datum.
Kahi i hāʻule ʻole ai ka MIM maʻamau—a pehea e hoʻoponopono ai ka ʻike kikoʻī
Hiki i kekahi ke hoʻopaʻapaʻa e hiki i kekahi mea hoʻolako MIM ke hana i ke kila kila inā hahai lākou i ka ASTM F2885. Akā ʻokoʻa ka moʻolelo o nā ʻano hemahema o ka honua. Ua ʻimi mākou i ka haʻi pinepine ʻana i nā noho valve 316L i ke koena binder carbon i hoʻopaʻa ʻia ma nā palena o ka palaoa - kahi kīnā ʻike ʻole ʻia e ka nānā ʻana akā he pōʻino ma lalo o ke kaomi cyclic. ʻAʻole wikiwiki ka hoʻoponopono ʻana; ke hoʻololi nei ia mai ka paraffin-based a i ka polyacetal-based binders *a me ka hoʻohui ʻana i ka lewa i hoʻopaʻa ʻia ma mua o ka hoʻomaʻemaʻe ʻana. No nā makahiki he 12 o ka holo ʻana o AMS 5387 cobalt alloy nozzles—nā mea me ka ʻike hoʻonui wela like akā ʻoi aku ka nui o ka uku no ka ʻōpala.
Hoʻololi pololei kēlā ʻike i ke kila kila. ʻAʻole mālama kā mākou metallurgists i ka 17-4 PH ma ke ʻano he "papa ʻē aʻe." ʻIke lākou i ka neʻe ʻana o kāna pane ʻelemakule inā e neʻe ka mahana sintering ± 5°C. Hōʻoia lākou i kēlā me kēia ʻāpana pauka e hiki mai ana me ka loiloi OES-ʻaʻole wale no Fe / Cr / Ni, akā no ka trace oxygen a me ka nitrogen e hoʻokele i ka pore morphology. Hoʻopaʻa lākou i kēlā me kēia ʻāpana: ka hau i loko o ke keʻena sintering, ka wikiwiki o ke kāʻei i ka umu debinding, a me ka haʻahaʻa ambient i ka wā o ka lawelawe ʻana i nā ʻāpana ʻōmaʻomaʻo. No ka mea, i loko o nā hui puʻupuʻu kiʻekiʻe, ʻaʻole i manaʻo ʻia ka hoʻololi ʻana o ka density 0.3% - ʻo ia ka hemahema o ka luhi ma mua o 12,000 psi.
Mai ka huki ʻana a hiki i ka lawe ʻana: He aha ke ʻano o ka "High-Precision" i ka hoʻomaʻamaʻa
Hoʻohana hewa ʻia ka "High-precision". ʻO ka pololei ʻoiaʻiʻo, ʻo ia ka mea hiki ke hoʻihoʻi ma waena o 500+ mau ʻāpana, ʻaʻole hoʻokahi CMM scan. 'O ia ho'i ka pa'a 'ana i ke kūlana 'oia'i'o ma nā puka Ø3.2 mm i loa'a he 42 mm kaawale i loko o 0.015 mm—* ma hope o ka ho'ēmi 'ana i ka sintering, *ma hope o ka ho'omaha 'ana i ke ko'iko'i, *ma hope o ka holo 'ana. Eia pehea mākou e hāʻawi ai:
- Ka mana komo: Hoʻāʻo ʻia ka pauka kila kuhili ʻole no ka hāʻawi ʻana i ka nui o nā ʻāpana (D50 ≤ 8.5 µm), ʻike ʻia, a me ke kahe kahe no ka ASTM B212
- Hōʻoia i ka hana: ʻO ke kaumaha ʻāpana ʻōmaʻomaʻo i hoʻopaʻa ʻia i kēlā me kēia lua; ana ʻia ka mānoanoa sintered ma o ke ala Archimedes ma ka mua a me kēlā me kēia hapa 50
- Manaʻo hope loa: 100% CMM nānā i nā datums koʻikoʻi; koho SEM/EDS ma luna o ka haʻihaʻi surfaces no ka pore kālailai
- Hiki ke hahai: Lawe ʻia kēlā me kēia ʻāpana i kahi palapala QR-coded e hoʻopili ana i ka pauka pauka, sintering run ID, log operator, a me ka hōʻike nānā hope.
ʻAʻole ʻoi loa kēia - ʻo ia ke kumu kumu no nā mea kūʻai aku i ka aila a me ke kinoea e koi ana i ka hoʻokō ASME B31.4 a i ʻole nā palapala EU PED 2014/68/EU. ʻAʻole mākou "hoʻohui i nā palapala hōʻoia ma hope." Kūkulu mua mākou i ka ʻōnaehana, a laila hoʻoponopono kūʻē iā ia.
Ke koho ʻana i kāu hale hana hoʻoheheʻe ʻia ʻana me ka hao hao—E nānā i ka palapala
Inā pili kāu papahana aʻe i nā ʻāpana MIM kila kila no nā manifold hydraulic, nā kumu pahū, a i ʻole nā hybrid cobalt-stainless maʻamau, e nīnau i ʻekolu nīnau ma mua o ke kau inoa ʻana i kahi PO:
- Hiki iā lākou ke hōʻike iā ʻoe i ka moʻolelo calibration hope o ka umu sintering—a hōʻoia i ka uhi ʻana i ka pae wela piha i hoʻohana ʻia no kāu papa?
- Hana lākou i nā ʻāpana ʻāpana metallographic ma nā ʻāpana hana, ʻaʻole wale i ka holo R&D?
- Ke kiʻi ʻia ke kaha kiʻi "Ra ≤0.4 µm ma ka ʻili hoʻopaʻa paʻa," hana anei lākou i ka mīkini * ma hope o * sintering—a i ʻole e hilinaʻi i ka poʻi lua e wehe i ka papa pahu paʻa?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. pane ʻae i nā mea ʻekolu. ʻAʻole ma ke ʻano he ʻōlelo kūʻai aku—akā ma ke ʻano he hana i kākau ʻia, ʻike ʻia i kā mākou ala hoʻokele ISO 9001 a kaʻana like i ka wā o ka loiloi ʻenehana. ʻAʻole mākou e kūʻai aku i ka hiki. Kūʻai mākou i ka wānana.
No nā noi koi kahi e pono ai ka MIM kila kila e hāʻawi i ka pololei a me ka hilinaʻi, e hui pū me a hale hana kila kuhiliʻole nona ke kaulahao waiwai piha—mai ka ʻepekema pauka a hiki i ka hoʻāʻo hana—ʻaʻole ia he pōmaikaʻi. ʻO ia wale nō ke ala e pale aku ai i ka hoʻolālā hou ʻana, nā hoʻokuʻu lohi, a me nā hemahema o ke kahua. ʻO ka wā e hiki mai ana i nā mea hana e mālama i ka metallurgy ma ke ʻano he ʻenekinia - ʻaʻole outsourcing.
