Investment casting usa fakitale

Mainjiniya ku U.S. akafuna zitsulo zolondola kwambiri—makamaka makina opangira ma hydraulic, mavavu amafuta ndi gasi, kapena ma pampu amphamvu—samakonda kuyamba ndi “fakitole yopangira ndalama ku USA.” Amayamba ndi vuto: gawo lomwe limalephera kupanikizika, limavala mofulumira kwambiri, kapena silingathe kupirira ± 0.005 ″ pambuyo pa chithandizo cha kutentha.

Ndiko kumene zenizeni zimasiyana ndi timabuku. Mashopu ambiri opangira ndalama zapakhomo amakhala ndi chitsulo cholimba cha carbon kapena 316 chosapanga dzimbiri. Ochepa amagwiritsa ntchito cobalt-nickel superalloys ngati AMS 5387 kapena T800-grade material. Ochepa amaphatikiza kuponya, makina a CNC amitundu yambiri, ndi kuyang'anira kogwirizana ndi GD&T pansi pa denga limodzi - ndikupereka nthawi zotsogola zokhazikika pama prototypes onse ndi ma 200-unit kupanga.

Chifukwa chiyani "fakitale yopangira ndalama ku USA" nthawi zambiri imakhala yomaliza pazigawo zofunika kwambiri

Tawunikanso ma RFQ opitilira 147 ochokera ku North America OEMs m'miyezi 18 yapitayi. Njira yosasinthika idawonekera: 68% yama projekiti idayimitsidwa - osati pamtengo kapena nthawi yotsogolera - koma pakutheka kwaukadaulo. Makamaka:

• AMS 5387 cobalt aloyi nozzles anakanidwa chifukwa cha micro-porosity mu as-cast makoma woonda kuposa 4.5 mm
• Pampu ya piston ya silinda yanyumba yomwe ikulephera kuyesa kwa hydrostatic pambuyo pa kupsinjika kotsalira kwa makina
• Non-standard winch center shaft rollers akumangirira panthawi yoyankhira njira chifukwa chopezacho chinalibe m'nyumba zachitsulo.

Kuthamanga sikuli kofunikira. Ndi kuya kwa luso. Kuwongolera ndalama zenizeni kumatanthawuza kuwongolera kapangidwe kambewu * musanapange * makina - osati kungogunda miyeso yodziwika pambuyo pake. Izi zimafuna kufufuzidwa kwazinthu zovomerezeka, zomangira zipolopolo zokhala ndi vacuum-assisted, tinjira zotsekera, ndi mbiri yang'anjo yomwe imayikidwa pa batch iliyonse - osasinthana.

Zomwe zimagwira ntchito: Kuphatikiza kuponyera + makina owongolera

Wogula m'modzi amafunikira ma valvu 12 a ma valve opangira ma subsea hydraulic manifold. Kufotokozera: AMS 5387, madoko 12 amkati okhala ndi ± 0.003 ″ kulolerana kwapamalo, kumaliza pamwamba Ra ≤ 0.8 µm pankhope zosindikiza, ma certs athunthu omwe amatha kusungunuka kuti asungunuke.

Wopereka ndalama wochokera ku U.S. adatchulapo milungu 14 ndipo adakana udindo wosokoneza pambuyo potulutsa. Sitolo yachiwiri idavomerezedwa, koma idafunikira mavenda atatu osiyana kuti aziponya, kutentha, ndi CNC yomaliza, yopanda mawonekedwe a GD&T omwe amagawana nawo.

Yankho lake linachokera ku malo ovomerezeka a ISO 9001 ku Qingdao, China: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Njira yawo idatseka kukhazikika koyambirira:

• Ingots yaiwisi ya cobalt-nickel yochokera kwa ogulitsa okha omwe ali ndi certification ya EN 10204 3.1 - ndikutsimikiziridwa kudzera mu mawonekedwe a OES atalandira
• Zipolopolo zopangira ndalama zomangidwa pogwiritsa ntchito silica sol + zircon slurry, zouma m'zipinda zoyendetsedwa ndi chinyezi (45% RH, 22 ° C), kenako zimawotchedwa 1020 ° C ndikunyowa kwa maola awiri.
• Kuponyedwa kutsanulidwa pansi pa bulangeti ya argon; kuziziritsa kumayang'aniridwa kudzera pa ma thermocouples ophatikizidwa mugulu lililonse la nkhungu
• Kujambula kulikonse kunkawunikiridwa 100% asanapange makina ovuta - palibenso

Zotsatira: Magawo onse 12 adachita kuyendera nkhani yoyamba. Zambiri za CMM zidawonetsa kupatuka kwapakati pa ± 0.0017″ pamalo adoko. Nthawi yotsogolera: 9 masabata. Palibe kukonzanso.

Zinayi zomwe sizingakambirane pakupanga ndalama kwapamwamba kwambiri

Ngati ntchito yanu ikuphatikiza ma aloyi a cobalt, kusindikiza mwamphamvu kwambiri, kapena kutsitsa kwamafuta ozungulira, tsimikizirani mfundo zinayi izi musanasainire PO:

1. Kufufuza kwa zinthu kumayambira pa kusungunuka - osati mphero. Funsani zipika za ng'anjo, malipoti owunikira ma ladle, ndi zolemba zotsimikizira za OES - osati ziphaso zokha.
2. Machining si "aftercasting" - amapangidwa pamodzi. Kodi atha kuyendetsa ma stack-ups a GD&T kudutsa shrinkage, kupotoza kwa kutentha, ndi kupatuka kwa zida? Ngati yankho lawo ndi "tidzazindikira," chokanipo.
3. Kukhulupirika kwapamtunda kumafunika kwambiri kuposa Ra. Pamalo osindikizira, funsani za subsurface microcrack kuzindikira (mwachitsanzo, fulorosenti penetrant + magnification) komanso ngati kutsirizitsa kumaphatikizapo kulowetsa kupanikizika (mwachitsanzo, kuwombera ≥ 200 MPa).
4. Kuyang'ana komaliza kumagwiritsa ntchito ma geji ogwira ntchito - osati CMM yokha. Nyumba ya pistoni iyenera kutsekedwa ndi manja ake. Mphuno iyenera kuyenda mkati mwa ± 2% ya zinthu zina. Funsani malipoti a mayeso okhala ndi zitsimikiziro zenizeni.

Ndani amapindula kwambiri ndi kuphatikiza kumeneku?

Izi si za mabulaketi azinthu kapena mabulaketi otsika kwambiri. Ndi za zigawo zomwe kulephera kumatanthauza kutsika, chiwopsezo chachitetezo, kapena kusagwirizana ndi malamulo. Gulu lathu la mainjiniya limawona ROI yapamwamba kwambiri kwamakasitomala muzochitika zitatu:

• Ma OEM akukonzanso zotulutsa zacholowa m'malo ena aloyi wapamwamba-Mwachitsanzo, kusintha maziko a pampu yachitsulo cha ductile ndi mitundu yochokera ku T800 kuti italikitse moyo wautumiki m'malo owonongeka amatope.
• Otsatsa a Aftermarket akufunika kusintha kofanana ndendende-makamaka mapulagi a aloyi a cobalt kapena ma nozzles omwe adazimitsidwa opanda zojambula za OEM zomwe zilipo (timasintha mainjiniya kuchokera ku zitsanzo zakuthupi + kusanthula mankhwala)
• Magulu atsopano opangira zinthu amatsimikizira mawonekedwe-fit-function asanapange zida zakufa kapena kupanga zida-kumene kuyika ndalama kumapereka kubwereza mwachangu pamtengo wotsikirapo

Inde, malowa ali ku Qingdao. Koma "fakitale yopangira ndalama ku USA" sizokhudzana ndi geography - ikufuna kukwaniritsa miyezo ya uinjiniya yaku US, kukakamiza kwa ASME B16.34, ndi ASTM A957 zamankhwala - mosasamala kanthu za zip code. Kutumiza kulikonse kumaphatikizapo zolemba zonse: ma cert, ma chart a kutentha, malipoti a CMM, ndi zolemba za NDT. Ndemanga iliyonse yojambula imaphatikizapo ndemanga za kupangidwa - kuwonetsa kusintha kwa makulidwe a khoma kapena ma angles omwe angatseke zotsalira za ceramic.

Yang'anani m'tsogolo: Malire otsatirawa si ng'anjo zazikulu kapena ma CNC othamanga. Ndiko kuwongolera njira zotsekera-pomwe kuponya deta yocheperako kumadyetsa mwachindunji ku chipukuta misozi, ndipo kuyerekezera kwamafuta panthawi yoyeserera kumasintha nthawi yonyowa munthawi yeniyeni. QINGDAO QIANGSENYUAN TECHNOLOGY ikuyendetsa kale mizere yoyendetsa ndi zomangamanga. Osati ngati lingaliro. Monga kuchita tsiku ndi tsiku.

Ngati polojekiti yanu yotsatira ikufuna kutsimikizika kwapang'onopang'ono-osati chiyembekezo cham'mbali-yambani ndi zomwe gawolo likufuna, osati komwe lapangidwira. Kulondola sikusamala za malire. Imayankha chilango.
