Apo mainjiniya anotsanangura a yakarasika wax investment kukanda fekitari kune yakakwirira-kutendeseka simbi zvikamu, ivo havasi kungotenga castings-vari kuchengetedza dimensional repeatability, microstructural control, uye kuvimbika kwekushanda pasi pemamiriro ezvinhu ebasa rakanyanyisa. Takaona mapurojekiti akawandisa achinonoka-kwete nekukanganisa kwekugadzira, asi nekukandira kusingaenderane. Imba yevharuvhu inopfuura kuongororwa kweCMM pane tembiricha yekamuri inogona kuchinjika mushure mekupisa kwekupisa kana iyo inowanikwa ikashaya yakasanganiswa yekupisa process kusimbiswa. Iyo cobalt alloy nozzle inogona kusangana nemakemikari specs pabepa asi inotadza mu-sevhisi kukukurwa kwevhu kana chimiro chezviyo chisina kutariswa paduru rese. Ndicho chikonzero nei kunyatsosatsanangurwa nekushivirira chete-kwakavakirwa mukati mekufamba kwebasa.
Nei Yakarasika Wax Investment Casting Inoda Vertical Kubatanidzwa-Kwete Kungowanikwa
Kukandira kwekudyara kunokunda uko kukanda jecha kusingakwanise: madziro akatetepa, akaomesesa emukati mavhesi, yakasimba GD&T callouts, uye yakanaka kupera kwepasi (Ra ≤ 1.6 µm). Asi iwo mabhenefiti anodonha pasina kubatana kwakasimba pakati pekugadzira patani, kuvaka shell, dewaxing, kupfura, kudurura, uye post-cast machining. Panzvimbo yedu muQingdao, isu hatibudise chero yeaya nhanho. Isu tinodzora cheni yakazara-kubva pasilicone yekushandisa yewakisi patani kusvika pakutsvaira-inobatsirwa ceramic goko rekuomeswa, kubva kune inodzorwa-tembiricha dewax oveni kusvika inert-gasi kudururwa kweAMS 5387 cobalt alloy pa1,480°C. Nei izvozvo zvine basa? Nekuti zvakasara wakisi zvinokonzeresa kutsemuka kwegoko. Kuomesa goko risina kuenzana kunokoka porosity. Thermal shock panguva ye dewaxing inogadzira microfractures isingaonekwe kuX-ray asi inouraya pasi pekumanikidzwa kwecyclic. Isu takayera kusvika ku22% kudzikiswa kwegoho rekutanga-pasi kana kutendeseka kwegomba kusingabvumidzwe paASTM F2897.
Iko Hunyanzvi Hwezvinhu Hunoparadzanisa Vatengesi Kubva Kuvashandi
Zvizhinji zvakawanikwa zvinokanda simbi isina tsvina kana ductile iron. Vashoma vanobata T800 cobalt-based alloys-kana kuita kudaro pasina kupira machinability. Takamhanyisa anopfuura chiuru nemazana mana ekupisa kweAMS 5387 kubvira 2019, imwe neimwe yakasimbiswa neOES spectroscopy uye batch-inoteedzeka kupisa-yekurapa matanda. Vatengi vanowanzobvunza kuti: "Unokwanisa here kubata ± 0.025 mm pane 320 mm piston pombi silinda imba?" Hongu-asi chete nekuti isu tinochina * mushure me* kuderedza kushushikana uye tisati tachembera kwekupedzisira. Kana tikakandira, kupisa-kuibata, tozomirira maawa makumi manomwe nemaviri tisati tagadzira, zvakasara zvinonetsa zvinokanganisa bore. Hatidarike danho iroro. Isu tinodzivirira zvakare mapfupi akajairika: hapana "generic" cobalt alloy substitutes, hapana off-spec filler simbi dzekugadzirisa weld, hapana sekondari isina kunyorwa mashandiro. Yese cobalt alloy plug, yega isiri-yakajairwa pombi chikamu, inotakura yakazara zvinhu certs, tensile bvunzo mishumo, uye kuoma mepu munzvimbo dzakakosha.
Chaiyo-yeNyika Maitiro Kuranga-Kwete Chete Zvitupa
ISO 9001 ndiyo tafura yemasiteki. Chinokosha ndechekuti kuomarara kunoshandura sei kune chikamu chako. Yedu yekuongorora protocol inotanga neinouya billet verification-kwete chete mill certs, asi ultrasonic bvunzo ye subsurface discontinuities. Panguva yekukanda, thermocouples inotarisisa mold preheat uye simbi inodurura tembiricha munguva chaiyo. Mushure mekuzunza, kukanda kwese kunovhenekwa dhayi inopinda mukati (ASTM E165) uye radiography (ASTM E94) isati yaitwa yakaoma machining. Kuongorora kwekupedzisira kunosanganisira CMM scanning yezvese GD&T maficha, optical kuyerwa kwenzvimbo yekuisa chisimbiso, uye inoshanda yekuyedza-senge hydrostatic pressure inoongorora pa1.5 × kushanda kudzvanywa kwemiviri yevharuvhu. Imwe yeEuropean hydraulic OEM yakaderedza kutadza kwemumunda ne68% mushure mekuchinja kune humburumbira hwedu dzimba - kwete nekuti kushivirira kwakaomeswa, asi nekuti isu takaronga uye nekudzora mavhiriji ekutsveyamisa gumi nemaviri ekudziya.
Kusarudza Iyo Yakarasika Yakarasika Wax Investment Casting Factory Zvinoreva Kubvunza Iyo Yakakodzera Mibvunzo
Usabvunze "Une ISO certification?" Bvunza: "Unosimbisa sei simba regoko usati wabvisa waxi?" Usabvunza "Ndeapi alloys aunokanda?" Bvunza: “Ndiratidze matanda matatu ekupedzisira ekurapa kupisa eAMS 5387—nemibairo inofambirana nayo.” Usabvunza "Ndeipi nguva yako yekufambisa?"
