ʻAʻole pili wale ke ʻano o ke kalai ʻana i ka wax no ka hana ʻana i nā hana hoʻoheheʻe wax nalo - ʻo ia ka unuhi kino mua o ka manaʻo hana i loko o kahi mea hana maoli. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ua kālai mākou ma luna o 12,000 wax patterns mai ka makahiki 2018-ʻo kēlā me kēia mea e hānai ana i nā mea hoʻokomo waiwai no nā puʻupuʻu hydraulic kaomi, nā hale pāpaʻi kobalt-alloy, a me nā huila winch center shaft e hana ana ma lalo o 350 bar a me 450 ° C. ʻO ka mea e hoʻokaʻawale ai i kahi ʻano kūpono mai kahi ʻōpala kumu kūʻai ʻaʻole ʻo ke kūpaʻa dimensional wale nō, akā ʻo ke kūpaʻa wela, ka hoʻokuʻu ʻana i ka ʻili, a me ka launa pū me nā ʻōnaehana ceramic shell. Ua aʻo mākou i kēia ma ke ala paʻakikī: hoʻokahi pūʻulu o AMS 5387 cobalt alloy nozzles i hāʻule i ka hoʻopili ʻana i ka pūpū i ka wā dewaxing—ʻaʻole ma muli o ke metala, akā no ka emi ʻana o ka wax kalai mua i ka 0.32% ʻoi aku ma mua o ka mea i ʻōlelo ʻia i ka wā o ka autoclaving mahu.
No ke aha ke kalai ʻana i ka wax performance e kuhikuhi ai i ka hoʻoheheʻe ʻana—ʻaʻole geometry wale nō
Hoʻohana ka hapa nui o nā hale hana i ka wax kalai ma ke ʻano he ʻano mold passive. Hana mākou iā ia ma ke ʻano he hoʻololi kaʻina hana. I loko o kā mākou ISO-compliant foundry, e hana ʻia kēlā me kēia hana wax i ʻekolu mau ʻanuʻu hōʻoia ma mua o ka hoʻokuʻu ʻana: ka hoʻopaʻa ʻana i ka thermal contraction profiling (ana ʻia ma 25 ° C → 65 ° C → 100 ° C), ka hoʻāʻo ʻana i ka hoʻopaʻapaʻa ʻana o ka shell i kā mākou zircon-silic slurry maʻamau, a me ka palapala ʻana i ke alahele o ka CNC. No ke aha mai? No ka mea, lilo ka 0.15 mm deviation i ka wax geometry i 0.22 mm i ke kila kuhiliʻole hope loa ma hope o ka emi ʻana, ka mālama ʻana i ka wela, a me ka wili ʻana—a ʻoi aku ia ma mua o nā kāhea GD&T ma nā hale pahu piston pump cylinder e 37%. Hoʻohana mākou i ʻelua ʻohana wax: haʻahaʻa hoʻoheheʻe (58–62°C) no nā kahawai hoʻoluʻu kūloko i loko o nā plugs alloy T800, a me nā huila microcrystalline ikaika kiʻekiʻe (72–76°C) no nā wili winch kaʻa kaʻa ʻāpana nui kahi e pale ai i ka paʻa ʻana i ka paʻa ʻana i ka wā o ka luʻu ʻana.
ʻEhā mau ʻano hāʻule ʻole o ka honua maoli—a pehea mākou e pale ai iā lākou
ʻAʻole hāʻule mālie ke kalai ʻana i ka wax no nā kaʻina hana o ka hale hana hoʻoheheʻe wax a hiki i ka haki ʻana o ka pūpū. Ma muli o ka 217 kumu kumu hoʻopaʻa ʻana ma waena o ʻAmelika ʻAmelika a me ka hoʻi ʻana mai o ka mea kūʻai mai EU, eia ka mea i haki maoli:
- ʻO ka haʻihaʻi ʻana o ka hysteresis: Hoʻomaʻamaʻa hou ʻia ka wax ma hope o ka paʻa ʻana hapa e ulu ai nā microfractures. Manaʻo mākou i ka hoʻoheheʻe ʻana i ka pōʻai hoʻokahi a me ka hoʻomalu ʻana i ka pae wela—ʻaʻole ʻae ʻia ka "mea hoʻoheheʻe hana".
- Paʻa paʻa ʻili: ʻAʻole ka pua ʻana o ka ʻakika stearic koena i ka uhi slurry. Loaʻa i kā mākou waxes he ≤0.8% mau momona momona manuahi; hōʻoia ʻia nā pūʻulu e hiki mai ana ma o FTIR spectroscopy.
- ʻO ka hoʻohuli ʻana i ka mea hana CNC: Holoi ka wax malū ma lalo o 12,000 RPM wili hope, e hana ana i nā hewa ʻanuʻu ma nā ʻano axis multi-axis. Hoʻopili mua mākou i nā poloka i 18°C ±1°C ma mua o ka hana ʻana—hōʻoia ʻia me nā thermocouple i hoʻokomo ʻia.
- ʻO ka neʻe ʻana o ka nui i ka wā e hui ai: ʻOi aku ka wikiwiki o ka hoʻonui ʻana o nā hui wax i hoʻopaʻa lima ʻia ma mua o nā mea makua. Ua hoʻololi mākou i ka hoʻoheheʻe ultrasonic no nā ʻāpana lehulehu a pau—e hōʻemi ana i ka ʻokoʻa hui mai ±0.13 mm a i ±0.04 mm.
ʻAʻole kēia mau manaʻo manaʻo. Hoʻopaʻa ʻia lākou i loko o kā mākou ʻikepili nonconformance me nā kiʻi, nā hōʻike CMM, a me nā ʻāpana metallurgical cross-sections-i loaʻa i nā mea kūʻai aku ma ke noi.
Pehea e hoʻololi ai ka hoʻohui pololei ʻana i ka wax i metala hiki ke wānana
He nui nā mea kūʻai aku e kūʻai aku i ke kālai wax. Kakaikahi ka mea e hoomalu ana ma hope o kona haalele ana i ka wili CNC. Ma QINGDAO QIANGSENYUAN, ua hoʻonohonoho ka poʻe ʻenekinia i hoʻonohonoho i nā mīkini kalai wax i ka ʻāʻī burnout shell, nānā i ka ninini ʻana i kōkua ʻia, a hōʻoia i ka paʻakikī hope loa ma ka ʻāpana cobalt-nickel. Hoʻopau kēia hoʻomau i nā āpau handoff. No ka laʻana: i ka wā i noi ai ka mea kūʻai aku i ka pōʻai ʻoi aʻe ma luna o kahi ʻāpana pamu AMS 5387, hoʻoponopono mākou i ka nui o ka wax (mai ka 0.91 g/cm³ a i ka 0.93 g/cm³), hoʻololi i ka ʻaoʻao o ka puʻu mahu dewaxing, a hoʻonui i ka manawa noho o ka shell preheat e 18 mau minuke — pau i ka holo hoʻokahi. Ka hopena: hoʻomaikaʻi ʻia ka pōʻai mai 0.082 mm a i 0.031 mm me ka ʻole o ka hoʻololi ʻana i ka huila metala a i ʻole ka mālama wela.
Hana wale kēia no ka mea e lawelawe ana kā mākou hale i ka hoʻolei ʻana, multi-axis machining, a me ka hoʻopau ʻana ma lalo o hoʻokahi hale. ʻAʻole hiki i ka mea hoʻolako wax waho ke calibrate i kā lākou hana ʻana i kāu ʻōnaehana pūpū kikoʻī, ka nui o ka umu ahi, a i ʻole ka hoʻolālā wili ma hope o ka hoʻolei ʻana. Hana ʻia kēlā calibration i ka manawa maoli-me ka ʻikepili.
Ke koho ʻana i ka Wax Kalai Ke koho ʻana i kāu hoa hana hana
Inā ʻoe e ʻimi nei i ke kālai wax no nā noi hale hana hoʻoheheʻe wax nalowale e pili ana i nā alloy cobalt, hydraulics kaomi kiʻekiʻe, a i ʻole nā hui pauma koʻikoʻi, e nīnau i kēia mau nīnau ma mua o ke kau ʻana i kahi kauoha:
- Hiki iā lākou ke hāʻawi i nā pihi hoʻopaʻa wela i ana ʻia ma kāu ʻāpana kikoʻī - ʻaʻole nā pahu hoʻāʻo maʻamau?
- Ke hōʻoia nei lākou i ka ikaika o ka pilina wax-to-shell me ka hoʻohana ʻana i kāu slurry haku mele a me nā ʻāpana dip?
- Ua hoʻonohonoho pono ʻia kā lākou polokalamu CNC no kāu paʻakikī paʻakikī—a i ʻole ke hilinaʻi nei lākou i nā hale waihona puke G-code generic?
- Hiki iā lākou ke ʻimi i kēlā me kēia poloka wax i kona ʻāpana maka, ka mōʻaukala wela, a me ka log machining?
ʻAe mākou i nā mea ʻehā. ʻAʻole ma ke ʻano he ʻōlelo kūʻai aku—akā ma ke ʻano he mau māka i kūkulu ʻia i kā mākou ʻōnaehana maikaʻi AS9100. Loaʻa i kēlā me kēia hoʻouna ʻana i ka wax i kahi palapala kikohoʻe me ka CMM scan overlays, thermal profile graph, and shell adhesion test results. No ka mea i ka hoʻolei ʻana i ka ʻoihana pono, ʻaʻole ka wax ka hoʻomaka. ʻO ia ka wahi nānā mua.
No ka hana like ʻana o ka ʻenehana no ke kalai ʻana i ka wax no ka hui ʻana o ka hale hana hoʻoheheʻe wax nalo— ʻoi aku hoʻi no nā alloy cobalt-nickel, nā kino kiʻekiʻe puʻe kiʻekiʻe, a i ʻole nā ʻāpana pauma maʻamau-e kipa. https://www.tsingtaocnc.com. Kākoʻo mākou i ka hōʻoia ʻana i ke kaha kiʻi, ka wehewehe ʻana o GD&T, a me nā manaʻo manaʻo no ka hana ʻana—ma mua o ka hoʻouka ʻia ʻana o ka poloka wax mua.
