Apo mainjiniya anotsanangura Investment yekukanda silicone sol foundry fekitori kugona, havasi kungotsvaga mutengesi-vari kutsvaga kugadzikana kwedimensional pasi pekunetseka kwekupisa, microstructural consistency kuyambuka 50-kg cobalt alloy pombi dzimba, uye zero kushivirira kweporosity muAMS 5387 mavharuvhu miviri. Ndicho chokwadi chekushanda chatinoona zuva nezuva paQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.-a Qingdao-based manufacturer apo "silicone sol" haisi buzzword; ndiyo binder system inobata 12-micron pamusoro pekupedzisira kushivirira paT800 alloy nozzles isati yabvisa waxing.
Takakanda zvinopfuura zviuru gumi nezvinomwe zvecobalt-nickel zvikamu kubva 2019-chimwe nechimwe chakateedzerwa kubheji, nhamba yekupisa, uye CMM yekuongorora rondedzero. Mune imwe North America hydraulic OEM purojekiti, piston pombi silinda imba yakakundikana katatu neanokwikwidza silica-bonded goko: microcracks akaumbwa panguva yekudonha kwemvura nekuda kwekusawirirana kwekuwedzera kwemafuta pakati peceramic shell uye T800 alloy core. Yedu silicone sol kuumbwa, yakarapwa pa180 ° C pachinzvimbo che120 ° C, yakaderedza kusara kunetseka ne41% - yakasimbiswa kuburikidza neXRD lattice strain strain analysis. Icho hachisi dzidziso. Ndosaka vatengi vachititumira GD&T-inorema dhizaini ine ± 0.015 mm yechokwadi chinzvimbo callouts-uye kutarisira kubvumidzwa kwechinyorwa chekutanga.
Chii chinoparadzanisa chokwadi Investment yekukanda silicone sol foundry fekitori kubva kune general-chinangwa caster? Zvitatu zvisingagone kutaurirana: Chekutanga, kudzora kwezvinhu. Isu tinongopa yakasimbiswa AMS 5387 cobalt alloy ingots ine yakazara mill test mishumo-kwete chete zvitupa zvekuenderana. Chechipiri, shell kutendeseka kusimbiswa. Boka rega rega regoko rinopinda mukuyedzwa kwesimba rinopisa pa1,150 ° C risati radururwa. Chechitatu, post-cast geometry chirango. Zvikamu zvejecha-zvakakanda zvinoderera zvisingatarisirwi; mari yekukandira uchishandisa silicone sol shrink mukati me ± 0.12% - asi chete kana iwe uchidzora wax pateni yekuwedzera, goko rinoomesa humidity (≤35% RH), uye kupfura rampu mitengo. Isu tinonyora ese ari matatu munguva chaiyo.
- Material mastery kupfuura spec sheets: Isu hatingoiti "process" T800-tinoziva eutectic melting point yayo inoshandura 23 ° C apo chromium inodonha 0.4%. Ndosaka yedu yevira thermocouples ichiyerwa zuva nezuva zvichipesana neNIST-inotevedzwa zviyero.
- Hapana "black box" machining: Yese simbi kana simbi inokandira inoenda yakananga kubva kugoko rekubuda kuenda kuCNC-hapana kupisa kwepakati kunze kwekunge kwatsanangurwa. Sei? Nekuti yedu-mumba 5-axis michina inobata ± 0.008 mm chinzvimbo chakarurama pane 300-mm-diameter pombi nheyo, kubvisa zvikanganiso zvekugadzirisa zvakare.
- Traceability inotanga isati yadirwa: Imwe neimwe mijenya inotakura tag yeQR-coded inobatanidza kune zvinhu certs, shell kuvaka matanda, kudurura tembiricha curves, uye yekupedzisira CMM mishumo - zvese zvinowanikwa kune vatengi kuburikidza yakachengeteka portal.
Vamwe vanogona kupokana kuti silicone sol yakawandisa kune yepakati-vhoriyamu inomhanya. Asi funga izvi: Mumwe mugadziri wemidziyo yemafuta ekuSoutheast Asia aida mayunitsi 220 epuragi risingaenzaniswi recobalt alloy. Vakwikwidzi vakataura kukanda jecha-ndokuzowedzera madhora gumi nemana ekugadzirisa maitiro mushure mekutanga-chinyorwa dimensional kukukurwa. Isu takaendesa kubvumidzwa kwekutanga-kumhanya tichishandisa silicone sol shells, nemadziro makubvu kusiyanisa akabatwa kune ± 0.18 mm kuyambuka 120 mm zvikamu. The cost delta? 7.3% yakakwira payuniti imwe-asi 100% yakaderera engineering rework, zero scrap, uye kuendesa mazuva gumi nemapfumbamwe pamberi pehurongwa. Kukandira kwakaringana hakusi kwekudzivirira machining - ndezvekutonga kupi uye kuti machini akawanda anoitika.
Tarisa kune ramangwana: Tiri kuwedzera simba redu resilicone kuti ribatanidze hybrid pedyo-net-shape casting + kunyatsojeka EDM yemukati yekutonhodza chiteshi mumiviri yevharuvhu yepamusoro-zvimiro zvisingabviri kudhiza post-cast. Asi nhasi zvakakosha zvinoramba zvisina kushanduka: kuendesa mavharuvhu anonamira pa420 bar pasina kuvuza, dzimba dzepombi dzinorarama hupenyu hwesevhisi yeawa gumi neshanu mune abrasive slurry, uye winch centre shaft rollers ine kuomarara gradients inosimbiswa nemicro-Vickers mepu. Kana application yako ichida kudzokororwa metallurgical kutendeseka - kwete kungo "kandwa kudhinda" -ipapo kodzero Investment yekukanda silicone sol foundry fekitori hazvitsanangurirwe ne square footage kana gore negore zvinobuda. Inotsanangurwa neiyo diki dhayamita yepore chikamu chako chakakosha chinogona kushivirira… uye maitiro ekuranga kuti avimbise.
