ʻEhia ka nui o ke kumukūʻai hoʻolei kālā no ka kg? Aia kēlā nīnau ma ka pākaukau o kēlā me kēia ʻenekini kūʻai—ma mua o nā RFQ, i ka wā o ka loiloi kālā, a ʻoi aku hoʻi i ka hoʻohālikelike ʻana i nā mea hoʻolako o waho. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ua ʻōlelo mākou ma luna o 1,200 mau papahana hoʻolei kālā mai 2018. Ua ʻike mākou i ka lele ʻana o nā huaʻōlelo mai $8.50 a i $47/kg—a ʻaʻole ma muli o nā pāʻani markup. ʻO ka ʻokoʻa mai nā kumu ʻehā: ke ʻano o ka alloy, ka paʻakikī o ka ʻāpana, ka nui o ka hui, a me nā koi hoʻopau. ʻOki kēia alakaʻi i ka walaʻau. Hāʻawi ia iā ʻoe i kahi kumu kūʻai kumu kūʻai pae-ʻoihana-ʻaʻole nā pae manaʻo, akā ʻo ka mea e hoʻoneʻe maoli ai i ka nila i ka holo ʻana o ka hana maoli.
ʻO Alloy Choice ka mea hoʻokele kumu kūʻai #1—ʻaʻole Geometry
Manaʻo ka nui o nā ʻenekinia i nā ʻano paʻakikī e hoʻonui i ke kumukūʻai hoʻolei kālā no ka kg ka nui. hewa. ʻO Alloy ka lanakila. Eia kā mākou e ʻike ai i kēlā me kēia lā:
- ʻO nā kobalt-nickel alloys (AMS 5387, T800) awelika $32–$47/kg — i alakaʻi ʻia e ka volatility maka, ka hoʻoheheʻe ʻana i ka hoʻoheheʻe ʻana, a me ka mālama ʻana i ka wela ma hope o ka hoʻolei ʻana no ka hoʻopaʻa ʻana i nā pae mua gamma.
- ʻO nā kila kila ʻole (CF8M, CF3M) ʻāina ma $18–$26/kg — ʻoi aku ka kiʻekiʻe ma mua o ke kila kalapona ma muli o ka maʻi chromium/nickel a me nā puka aniani kemika paʻa.
- Paʻa paʻa ka hao hao (ASTM A) ma $9.50–$13.50/kg — wahi heheʻe haʻahaʻa, liʻiliʻi liʻiliʻi, kala ʻana i ka ʻōnaehana pūpū.
Ua ʻōlelo mua mākou i kahi hale pahū hydraulic ma T800 cobalt alloy ma $41.20/kg. Ua hāʻule ka geometry like ma ASTM A351 CF8M i $22.60/kg. ʻAʻohe hoʻololi hoʻolālā. Metallurgy wale nō. Inā ʻae kāu kikoʻī i ka hoʻololi ʻana i nā mea waiwai - ʻoiai me nā tradeoffs tensile liʻiliʻi - loaʻa koke ʻoe i ka leverage ma kumukūʻai hoʻolei kālā no ka hale hana kg kumu kūʻai.
Mea Paʻakikī—Akā Ma hope o ka Paʻa ʻia ʻana o nā Ana Koʻikoʻi
ʻAʻole manaʻo ʻo "Complex" he "uku kūʻai" - ke ʻole ia e koi i ka hana lima. ʻOi aku ka maikaʻi o ka hoʻolei kālā ʻana ma nā ʻano kūlohelohe, nā ala i loko, a me nā paia lahilahi. ʻAʻole ka curvature a i ʻole contour ka mea e hoʻohui ai - ʻo ia nā hiʻohiʻona e wāwahi ai i ka automation: nā undercuts e koi ana i ka hui lima-wax, nā puka makapō i ʻoi aku ka hohonu ma mua o 8x anawaena, a i ʻole ka hoʻopau ʻana o ka ʻili ma mua o Ra 1.6 µm me ka ʻole o ka mīkini.
Ma kahi kauoha hou no nā hale pahu piston pump cylinder, ua ʻōlelo ka mea kūʻai aku i ka ± 0.05 mm ka mānoanoa o ka pā ma kahi o 220 mm ID. ʻO ia ka mea i hoʻomaka i ka nānā ʻana i ka CMM piha ma kēlā me kēia ʻāpana—a he 14% premium ma mua o ± 0.15 mm maʻamau. Akā i ko lākou hoʻomaha ʻana i ka hoʻomanawanui i ± 0.10 mm ma nā ʻaoʻao i hoʻopaʻa ʻole ʻia, ua hāʻule ke kumu kūʻai he $2.30/kg me ka hopena hana ʻole. ʻO kā mākou lula: e wehewehe mua i nā datum koʻikoʻi. A laila e hoʻoholo ka hoʻolei ʻana i ke koena.
Hoʻololi ka Volume i nā mea a pau—Ma lalo o 500 ʻāpana
ʻO ke kumu kūʻai hoʻolei kālā no kēlā me kēia kg hale hana e hāʻule nui ana ma waena o 1-50 mau ʻāpana a me 500-2,000 mau ʻāpana—akā he pāpū ma hope o ia. No ke aha mai? ʻO ka amortization mea hana. He $2,800–$4,500 ka mea paahana kumu hana wax no kahi hapa paʻakikī. Ma 50 pcs, ʻo ia ka $56-$90 i hoʻohui ʻia i kēlā me kēia ʻāpana. Ma 1,000 pcs? $2.80–$4.50 wale nō.
Hoʻopili pololei mākou i kēia. No ke kino kiwi puʻu kila kila (1.8 kg/unit), ʻo kā mākou kumu kūʻai hoʻoheheʻe kālā i ʻōlelo ʻia no kēlā me kēia kg hale hana:
- $28.40/kg ma 50 pcs (me nā mea hana piha + 3-shell iterations)
- $21.90/kg ma 500 pcs (mea hana piha amortized, optimized shell drying cycle)
- $20.30/kg ma 2,000 pcs (hoʻonui ʻia ka hoʻouka ʻana o ka umu ahi, hoʻemi ʻia i ka 2.1%).
ʻAʻohe kilokilo. ʻO ka physics wale nō, ka mana kaʻina hana, a me nā hoʻonohonoho hou.
ʻAʻole koho ʻia ka hoʻopau ʻana—ua kūʻai ʻia ma ka ʻili, ʻaʻole ma ka ʻāpana
He kakaikahi ka "As-cast" i nā noi ʻoihana. Pono ka hapa nui o nā mea kūʻai aku i ka liʻiliʻi o ka vibratory deburring a me ka pana kī. Akā ʻo kēlā me kēia ʻanuʻu hou e hoʻohui i ke kumukūʻai linearly:
- Vibratory deburr + alumina blast: +$0.85/kg
- Electropolish (Ra ≤ 0.4 µm): +$4.20/kg
- Passivation (ASTM A967 Nitric): +$1.10/kg
- ʻO ka wili ʻana o nā maka sila: +$6.90/kg (ana ʻia i kēlā me kēia maka, ʻaʻole i kēlā me kēia ʻāpana)
Ua hana hou mākou i kahi kauoha nozzle cobalt alloy kahi i noi ai ka mea kūʻai i ka electropolish *a me ka wili kūloko ma luna o ʻelua mau noho puka liʻiliʻi. ʻO ka hoʻopau wale ʻana i hoʻohui ʻia he $11.30/kg—ʻoi aku ma mua o ke kumukūʻai hoʻoheheʻe kumu no kēlā papa alloy. Haʻawina: e wehewehe wale i nā sila, nā paheʻe, a i ʻole nā hoa. Hoʻokuʻu i ka hoʻopau hoʻonaninani ke ʻole ke koi ʻana i ke kūpaʻa corrosion a i ʻole ka calibration kahe.
Hoʻomaka ka loaʻa ʻana o ke kumu kūʻai maoli me kāu kaha kiʻi—ʻaʻole kāu kālā
He mea ʻole nā huaʻōlelo maʻamau. Pono ke kumu kūʻai hoʻolele hoʻokomo kālā maoli no ke kumu kūʻai o ka hale hana GD&T, nā palapala palapala waiwai (AMS, ASTM, EN), a me nā memo hoʻopau—ʻaʻole wale ʻo "stainless steel, surface good." Ma QINGDAO QIANGSENYUAN TECHNOLOGY, nānā kā mākou hui ʻōlelo i kēlā me kēia kiʻi no ka hana ʻana ma mua o ka haʻi ʻana. Hōʻike mākou i nā pilikia: ʻino ka wela ma nā lima lahilahi lōʻihi, ka pohā ʻana o ka pūpū ma nā radii kūloko ʻoi, a i ʻole nā pilikia ejection wax i loko o nā ʻeke hohonu. He 48 mau hola ia loiloi—a mālama i nā pule ma hope.
Inā ʻoe e loiloi ana i nā mea hoʻolako, e noi i kā lākou helu ʻōpala maʻamau ma kāu papa alloy, nā manawa noho o kā lākou ʻōnaehana shell, a inā paha iā lākou kā lākou keʻena slurry ceramic. ʻOi aku ka maikaʻi o kēlā mau kikoʻī ma mua o kekahi pepa kumu kūʻai. A e hoʻomanaʻo: ʻo ka ʻōlelo haʻahaʻa haʻahaʻa e hūnā pinepine i nā kumukūʻai hana hou, lohi ka nānā ʻana, a i ʻole ka hoʻoheheʻe ʻana i ka nui ma nā pūʻulu.
No ka pololei, hiki ke hana kumukūʻai hoʻolei kālā no ka hale hana kg koho—hoʻokumu ʻia i ka ʻikepili kaʻina hana maoli, ʻaʻole nā lau palahalaha—hoʻomaka me kahi kiʻi i hoʻopaʻa ʻia a me nā kikoʻī mea i hōʻoia ʻia. Ke koena mahope.
