Ke hōʻike ʻia e nā ʻenekinia kiʻekiʻe precision magnesium alloy make hoolei hale hana, 'A'ole lākou e noi wale mai i mea ho'olako—ke koi nei lākou i ke kūpa'a dimensional ma lalo o ka paikikala wela, ka like 'ole o ka microstructural ma waena o nā pauku pā lahilahi, a me ka ho'oku'i 'ole i ka ikaika tensile ma nā mahana lawelawe ki'eki'e. Hāʻawi ka magnesium alloys e like me AZ91D, AM60B, a me WE43 i nā ratio like ʻole o ka ikaika-a-kaumaha-akā inā wale nō ke kaʻina hana hoʻoheheʻe make e hoʻomalu i ka hydrogen porosity, hoʻemi i ka soldering make, a hoʻopaʻa i nā tolerances ± 0.05 mm ma nā hiʻohiʻona liʻiliʻi e like me ka 0.8 mm mānoanoa pā. ʻAʻole loaʻa kēlā pae o ka mana i loko o nā waihona kumu.
Ua hoʻolei mākou ma luna o 12,000 WE43 hale magnesium no nā mea hoʻokele hydraulic aerospace-a ua hala kēlā me kēia pūʻulu i ka nānā ʻana i ka X-ray 100% me ka ʻole o ka emi ʻana o lalo. No ke aha mai? No ka mea, ʻaʻole pili ka hoʻoheheʻe ʻana i ka magnesium i nā mīkini ʻoi aku ka nui a i ʻole ka wikiwiki wikiwiki. E pili ana i ka mālama ʻana i ka wela hoʻoheheʻe ʻana i loko o ± 3°C, ka mālama ʻana i ka pau ʻana o ka ʻili ma lalo o Ra 0.4 μm, a me ka hoʻohana ʻana i ka hoʻopiha ʻana i kōkua ʻia e hoʻopau i ka hoʻopaʻa ʻana i ke kiʻiʻoniʻoni oxide. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ʻaʻole mākou e mālama i ka magnesium ma ke ʻano he "aluminika māmā," akā ma ke ʻano he reactive, oxygen-pōloli metala e koi ana i nā mea hana i hoʻolaʻa ʻia, ka pale kino inert-gas, a me ka nānā ʻana i ka puʻe o ka lua.
ʻO ka hapa nui o nā hemahema o ka hoʻoheheʻe ʻana i ka magnesium e hoʻihoʻi ʻia i ʻekolu mau āpau hiki ke pale ʻia: ka hoʻomaʻemaʻe ʻana i ka palaoa i ka wā paʻa, ka hoʻokaʻawale ʻana i ka māhele intermetallic ʻole (ʻoi aku ka Mg.17Ua ʻōlelo ʻo Al12), a me ka hoʻoheheʻe ʻana ma hope o ka hoʻolei ʻana mai ke koena o ke kaumaha. Hoʻopili mākou i kēlā mau āpau ma ka hoʻohui ʻana i ka hoʻohālikelike hoʻolei ʻana me ka palapala ʻāina thermocouple in-die maoli - a laila e hōʻoia i kēlā me kēia geometry mold e kūʻē i ka ASTM B94-22 tensile bar a me ka ISO 11992-2 leak-rate hoʻāʻo. Loaʻa kā mākou mau prototypes magnesium one i Cpk ≥ 1.67 ma nā kelepona GD&T koʻikoʻi; paʻa ka holo ʻana o ka hana ± 0.03 mm ma ka coaxiality ma waena o nā ʻawaʻawa a me nā flanges kau ʻana-me ka ʻole o ka mīkini lua.
ʻO ka hoʻohui pololei ʻana i ka ʻokoʻa. ʻOiai he nui nā hale hana i kapa ʻia ʻo "precision" i waho i ka mālama wela a i ʻole ka hoʻopau ʻana i ka CNC, ke hoʻomalu nei mākou i ke kaulahao piha: hoʻoheheʻe ʻia ka magnesium alloy i nā crucibles graphite ma lalo o SF6/CO2 uhi kinoea, kiʻekiʻe-mehameha make hoolei ana ma 720–740°C hehee ai ka wela, T6 solution annealing me ka mana ramp rates, a me ka hope CMM hōʻoia me Zeiss CONTURA G2 me tactile scanning. Hoʻopau kēia i nā hewa o ka interface — ʻaʻohe helu kuhi hewa ma waena o ka hale hana a me ka hale kūʻai mīkini, ʻaʻohe mōʻaukala wela huna e pili ana i ka machinability. I ka wā i makemake ai ka OEM pauma ʻEulopa i nā hale kaila magnesium me 0.1 mm palahalaha ma ka 220 mm maka a me 300 MPa ikaika hua, ua hoʻopuka mākou i nā ʻatikala mua i nā lā 18-ʻaʻole no ka wikiwiki ʻana, akā no ka mea ʻaʻohe lohi o kā mākou palapala kaʻina hana.
ʻOi aku ka mea nui o ka hana maoli ma mua o nā pepa kikoʻī. Ua hōʻike aku kekahi mea kūʻai aku he 40% ka lōʻihi o ke ola lawelawe ʻana ma luna o nā huila huila winch center shaft ma waena o nā alumini like ʻole—ma hope o 12,000 mau pōʻai ma lalo o 85 kN radial load a me ka paʻakai paʻakai. No ke aha mai? ʻO kā mākou AMS 5387-compatible cobalt-nickel hoʻokomo i hoʻopaʻa ʻia i loko o nā hale magnesium i mālama ʻia ka paʻakikī ma luna o 42 HRC ʻoiai ʻo ka mea hoʻohui kumu e komo i ka ikehu vibration. E hana wale ana kēlā hoʻolālā hybrid i ka wā e hoʻokaʻawale ai nā hui hoʻolei a me ka mīkini i nā hālāwai loiloi ʻenekinia like - a i ka wā e hoʻopili ai ka traceability waiwai i kēlā me kēia helu ʻāpana i kāna ʻāpana ingot kumu, ka umu ahi, a me ka hōʻike hoʻāʻo tensile. ʻAʻole mākou e hui wale i ka ISO 9001:2015—e hoʻokomo mākou i nā loiloi pilikia ʻano AS9100 i kēlā me kēia kickoff pāhana magnesium hou.
Inā makemake ʻoe i kahi kiʻekiʻe precision magnesium alloy make hoolei hale hana e mālama ana i ka magnesium ma ke ʻano he mea hana ʻenekinia-ʻaʻole he mea maʻalahi wale nō - pono ʻoe i ke kaʻina hana, ke kuleana metala, a me ka hoʻomanawanui ʻole no ka hana kuhi. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. hāʻawi i kēlā ʻano koʻikoʻi ma waena o nā manifold hydraulic, nā kumu paila, a me nā ʻāpana kaʻa koʻikoʻi. Hoʻomaka ka pololei ma kahi e hui ai ka hehee me ka make—a paʻa i loko a hiki i ka nānā hope ʻana.
