Kana mainjiniya achinge ataura kuumbwa kwegoko resimbi, havasi kungosarudza maitiro-vari kusarudza nzira yekudzikama, kutendeseka kwepamusoro, uye inodzokororwa microstructure muzvikamu zvinoshanda pasi pekumanikidzwa kwakanyanya, tembiricha, kana kupfeka. A shell mold casting factory inofanira kuita zvinopfuura kudurura simbi yakanyungudutswa mudeko rejecha rakasungirirwa resin. Inofanirwa kubhuroka kudzora kwesimbi nekugadzirira machining-kunyanya kana chikamu chacho chiri cobalt-alloy pombi yekugara yakarongerwa 350 bar kana AMS 5387 valve body inoda ± 0.02 mm GD&T kutevedzera.
Nei Shell Mold Casting Inoendesa Kune Mamwe Maitirwo Anonetsekana
Shell molding inogara pakati pekukandira jecha nekukanda mari: nekukurumidza kupfuura kurasika-wakisi, kusimba-kushivirira pane girinhi-jecha, uye zvakanyanya scalable kupfuura ceramic shell yepakati-vhoriyamu maindasitiri anomhanya. Simba rayo riri mugoko rakatetepa, rakaomarara-kazhinji 6-10 mm gobvu-rakagadzirwa nekuputira simbi inopisa patani (180-250 ° C) ne phenolic resin-yakavharidzirwa silica jecha. Zvakaguma nei? Kupedzwa kwepamusoro kweRa 2.5-6.3 μm, kushivirira kwemutsara kunosvika ± 0.3 mm pazvimiro zviri pasi pe300 mm, uye zvishoma zvinodikanwa (0.5 ° -1.5 °). Asi nhamba idzodzo dzinoreva zvishoma pasina chirango chemaitiro.
Isu takaona vatengi vachichinja kubva pakukanda jecha kuenda kugomba chete kuti vatarise warpage mumasilinda mahombe edzimba-kusvika vaona kuti chikonzero chaive chisiri chekuumbwa, asi kusawirirana kwepakati kudhinda kurongeka panguva yekugadzira goko. Panzvimbo yedu muQingdao, ganda rega rega rinoona ongororo yekumisikidzwa isati yavhara. Boka rega rega rejecha rakavharwa neresin rinoedzwa kuyerera, kusimba kwesimba, uye kusara kwekutsva. Uye yese yakadururwa inotonhorera inotonhorera pasi peinodzorwa ambient kuyerera-kwete kumanikidzirwa kudzimwa-kudzivirira kusara kwekushushikana kwekudzika muzvikamu zvepamusoro-alloy.
Vertical Integration Haisi-Kukurukurirana kune Mishoni-Yakakosha Zvikamu
Kuumba Shell chete hakuvimbisi kushanda kwevhavhavhavha. Chinokosha chii chinoitika pamberi uye shure: zvinhu traceability, kupisa kurapwa kuwiriranisa, uye CNC-yakagadzirira datum tsananguro. Ndicho chikonzero chokwadi shell mold casting factory anofanira kuva muridzi—kana kutonga zvakasimba—cheni izere.
- Pre-cast: Certified T800 cobalt-based alloy ingots, yakasimbiswa kuburikidza nePMI neOES; saizi yezviyo inodzorwa kuburikidza neladle simbi uye kudurura tembiricha yekutarisa (± 5 ° C kushivirira)
- Panguva yekukanda: Chaiyo-nguva yekupisa yekufungidzira ye mold nzvimbo yekuona nzvimbo dzinopisa dzinokonzera micro-shrinkage muzvikamu zvitete-madziro
- Post-cast: Stress-relief annealing muvira-inodzorwa nemhepo, ichiteverwa ne3-axis CMM yekuongorora *pamberi* machining-uchishandisa as-cast datum kuratidza kukanganisa.
Kubatanidzwa uku kunobvisa handoffs uko dimensional drift inoungana. Mutengi paakatitumira piston pombi silinda yedzimba yekudhirowa ine gumi nembiri dzakaomarara zvibore uye 0.015 mm kushivirira chinzvimbo, takabata kupindirana pakati pekubvumidzwa uye yekupedzisira machining stock panguva yekuongorora kweinjiniya-kwete mushure mekuongorora-chinyorwa chekutanga.
Material Mastery Inotsanangura Miganhu Yekuita
Cobalt-nickel alloys seAMS 5387 haiite seyakajairwa 316 isina tsvina. Kuwanda kwavo-kuomesa basa, kuderera kwemafuta, uye abrasive carbide phases inoda kukanda paramita yakarongerwa *iyo chaiyo chemistry*-kwete generic "superalloy" marongero. Mamwe ma foundries anobata ese cobalt alloys zvakafanana. Isu hatidaro.
Mukuita, izvi zvinoreva kugadzirisa ukobvu hwegoko ne ± 1.5 mm zvichienderana nechikamu chemodulus, kushandura gating velocity kudzivirira kukukurwa kwemanozzles akanaka, uye kubata nguva yekusimba mukati memasekonzi makumi mapfumbamwe emapulagi ari pasi pe40 mm dhayamita. Takagadzira pamusoro pe17,000 AMS 5387 nozzles kubva 2021. Batch imwe neimwe inosanganisira yakazara kupisa traceability, tensile test report per ASTM E8, uye microstructure mapikicha anoratidza yunifomu eutectic carbide kugovera-hapana masumbu ega ari pedyo nekupinda gedhi.
Iyoyo nhanho yekutonga inoparadzanisa mutengesi anotakura castings kubva kune anotakura * yakasimbiswa inoshanda zvikamu*. Kana chikumbiro chako chinosanganisira cyclic kurodha pamusoro pe200 MPa kana kuratidzwa kune H₂S-yakapfuma mafuta & gasi hova, kuenderana kwezvinhu hakusi kwesarudzo-ndiyo mutsara wekutanga wekudzivirira kukundikana.
Kusarudza Waunoshanda Naye Kunoreva Kubvunza Mibvunzo Yakakodzera
A shell mold casting factory inofanirwa kupindura izvi-kwete mumabhurocha ekushambadzira, asi munhaurirano yeinjiniya:
- Unogona kundiratidza mabheji matatu ekupedzisira eAMS 5387-kusanganisira saizi yezviyo, carbide volume %, uye interdendritic spacing?
- Iwe unosimbisa se-cast geometry * isati yagadzirwa, uchishandisa madhamu echinyakare ekukanda-kwete chikamu chekupedzisira chezvikamu?
- Ndeipi yako yepamusoro-chidimbu huremu hwegoko-yakaumbwa cobalt alloys-uye iwe unogadzirisa sei kupisa kwemafuta kusiyanisa pakati peiyo renji?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inosangana nemibvunzo iyoyo nemaitirwo akanyorwa, kwete zvipikirwa. Yayo ISO-inoenderana nzvimbo inotsigira goko rekuumbwa kwesimbi, simbi, tsvina, uye yakakwirira-inoshanda cobalt-nickel alloys-ine CNC machining, kupisa kupisa, uye kupera kwepasi pasi pedenga rimwe. Inoshanda hydraulic OEMs, offshore equipment integrators, uye nyanzvi dzekuvaka pombi mhiri kweNorth America, Europe, uye Southeast Asia-kwete semutengesi, asi sekuwedzera kwechikwata chavo chekugadzira engineering.
Tichitarisa kumberi, indasitiri inozoda kubatanidzwa kwakasimba kwekukanda uye ekuwedzera maitiro, yakawedzera chitupa chenyukireya-giredhi uye API 6A maapplication, uye dijitari mapatya kusimbiswa kune yakaoma kuyerera-nzira yekukanda. Chizvarwa chinotevera shell mold casting factory haizongodzokorora geometry. Ichafanotaura kuita - kutanga negoko.
