Apo mainjiniya anotsanangura silicon mold yekukanda fekitori masevhisi emhando yepamusoro-yesimbi simbi, iwo haasi kungoodha zvikamu-vari kuchengetedza dimensional kugadzikana pasi pe300 MPa hydraulic mitoro, microstructure kuenderera mushure mekupisa kupisa, uye kutendeseka kwepasi kunopona abrasive slurry mumapombi emuoiri. Ndicho chokwadi chekushanda kuseri kwekukandira chaiko nhasi-kwete kushivirira kwefungidziro padhirowa, asi kuita kunoyerwa mubasa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshanda imwe yezvishoma zvivakwa zvekugadzira muChina uko silicon mold casting (yakasarudzika musiyano wekudyara kwekudyara uchishandisa silica-based ceramic shells) inoiswa zvakarongeka kune cobalt-nickel alloys seAMS 5387 uye T800. Takakanda pamusoro pegumi nemaviri ekumanikidza mavharuvhu miviri ye subsea hydraulic control units kubva 2021-imwe neimwe inoda ± 0.05 mm yakakosha bore concentricity, zero yemukati porosity paASTM E192, uye yakazara traceability kubva mbishi alloy lot kusvika yekupedzisira CMM report. Chiyero ichocho chekuenderana hazviitike netsaona. Zvinoitika kana kukanda kusiri kwakasarudzika kubva mukugadzira, kupisa kupisa, kana GD&T kusimbiswa-uye kana batch yega yega inotanga nezvitupa zvakasimbiswa zvezvinhu, kwete vimbiso dzevatengesi.
Sarudzo nhatu dzehunyanzvi dzinopatsanura kushanda kwesilicon mold kukanda kubva pakukandwa kunogamuchirwa-uye izvi zvinotsanangura izvo vatengi vanoedza chaizvo mumiedzo yemumunda:
- Shell composition control: Standard silica sol binders inotsemuka pamusoro pe1,100 ° C panguva yekudira cobalt alloy. QINGDAO QIANGSENYUAN inoshandisa yakagadziridzwa colloidal silica + fused silica aggregate system yakatarwa kusvika 1,280°C-yakasimbiswa kuburikidza neanopisa giravimetric ongororo pane yega yega goko. Izvi zvinobvisa microfissures iyo inozoratidza kuneta-inotangisa pamusoro mavhaira mupombi humburumbira dzimba.
- Directional solidification manejimendi: Kune dzimba dzepiston pombi humburumbira ine 42 mm madziro ekuchinja, isu tinonangisa zvinokandwa pa17 ° kubva pakatwasuka muchoto uye tinoshandisa mahwendefa ekutonhora munzvimbo dzakakora zvikamu. X-ray tomography inosimbisa kuyerera kwezviyo kwakananga kunoenderana nemavekita ekushushikana-yakakosha kune AMS 5387 zvikamu zvinoshanda pa450°C.
- Post-cast dimensional envelope kukiya: Kusiyana nekukandwa kwejecha, silicon mold castings inobata zvakasimba se-cast dimens-asi chete kana machining maallowance akagadzirwa pateni, kwete kufungidzira. Chikwata chedu chinovaka 0.3-0.5 mm stock munzvimbo dzakakosha dzekuisa chisimbiso, yobva yaona post-machining kukanganisa nelaser tracker alignment pazvikamu zvakasungirirwa. Vatengi vanoshuma 40% kushoma kwekutanga-chinyorwa kurambwa pawinch centre shaft rollers nekuda kweizvi.
Vamwe vanogona kupokana kuti CNC machining chete inopa kurinani kurinani pane kukanda. Asi izvo zvinopotsa fizikisi: kugadzira 120 kg T800 alloy block kuita 22 kg pombi nheyo inorasa 82% yemutengo wezvinhu-uye inounza kusara kunetseka kunokanganisa kuneta hupenyu mukurodha cyclic. Silicon mold casting inotanga padyo-neti chimiro. Ipapo nzvimbo dzedu dzakabatanidzwa dze5-axis milling dzinobvisa chete zvinodikanwa-kuchengetedza chimiro chezviyo, kubvisa nhanho-yekudzoreredza annealing, nekucheka nguva yekutungamira nemavhiki 3.7 maringe neimwe nzira dzakanyatsogadzirwa. Imwe North America OEM yakachinja tambo yayo yecobalt alloy nozzle kune iyi hybrid process uye yakadzikisa mutengo wechikamu ne29% uku ichiwedzera hupenyu hwesevhisi kubva pa8,200 kusvika 14,600 maawa ekushanda.
Izvo vatengi vanoramba vachibvunza-uye izvo zvatinopindura tisati tatora-ndeye nzira yekudzivirira matatu anowanzo kutadza modhi mune yakakwira-alloy silicon mold castings:
- Microshrinkage muzvikamu: Yakagadziriswa nemafuta ekuenzanisa egating masisitimu uye chaiyo-nguva yekunyunguduka tembiricha yekutarisa (± 1.5 ° C) panguva yekudira-hapana kunze.
- Surface roughness kusaenderana: Yakagadziridzwa kuburikidza neatomatiki goko dipping matenderedzwa akarongedzerwa kune viscosity, pH, uye particle size kugovera-kwete mushandisi kunzwa.
- Dimensional inodhiraivha mumabatches: Inodzivirirwa nekuchengetedza master mapatani mukudzikama Invar tooling uye kusimbisa yega yega yega yemukati geometry ine optical profilometry pre-assembly.
Isu hatitore kukanda senzira yakazvimirira. Yese silicon mold yekukanda basa inopinda panguva imwe chete yeinjiniya ongororo: Chikamu chejometry chakagadziridzwa kune chinongedzo chakasimba? Iyo yakatsanangurwa AMS 5387 yekupisa yekurapa kutenderera inoenderana neiyo yekukanda se-yakasimba saizi yezviyo? Ko iyo inodiwa Ra 0.4 μm kupera inogona kuwanikwa pasina kugaya kwechipiri kunoisa njodzi kukuvara kwepasi? Izvi hazvisi zvinhu zvekuongorora. Idzo nhaurirano-dzakanyorwa, dzemazuva, uye dzakasungirirwa kuhurongwa hwebasa.
Tichitarisa kumberi, iro chairo bhodhoro harisi kugona - kudzika kwechitupa. Gore rinouya, QINGDAO QIANGSENYUAN inowedzera ISO 13485 chiyero kuti ivhare zvekurapa-giredhi cobalt-chromium orthopaedic zvikamu, uye inotanga yechitatu-bato kusimbiswa kwayo kwesilicon mold process ichipokana neNADCAP AC7118 Rev. D yekukandira mumhepo. Sei? Nekuti vashandisi havachabvumi "yakashanda kekupedzisira." Vanoda kudzokororwa kwakanyorwa-kupfuura zvinhu, geometries, uye kugadzirwa kunomhanya. Kana yako silicon mold yekukanda fekitori inogona kuendesa AMS 5387 pombi zvikamu zvine simbi yakazara traceability, CMM-yakasimbiswa yakakosha maficha, uye zero isiri-conformance mishumo pamusoro pemwedzi gumi nesere inoteedzana, unomira kuve mutengesi. Unova musimboti.
