Vanhu vazhinji pavanonzwa 'masevhisi ekuisa mari', vanofungidzira bhurocha rinopenya rine zvikamu zvinopenya, zvakaoma kunzwisisa. Chokwadi, kugaya kwezuva nezuva kwacho, kwakashata uye kunonakidza. Pane imwe pfungwa isiriyo yekuti zvese ndezvekuwana padhuze-net chimiro uye ndizvozvo. Asi kukosha chaiko, chikamu chinochengeta mainjiniya nemaneja ekutenga zvinhu husiku, hachingori chimiro - ndiko kutendeseka kwechimiro ichocho muchinhu chakakodzera, batch after batch, pasina dhirama. Ndipo panopinda makumi emakore ekushanda mavanga, kwete makore echiitiko chete.
Iyo Shell Game: Iri Kupfuura Ingori Jecha
Wese munhu muindasitiri anotaura nezve shell mold process. Ndiwo moyo we Investment casting. Asi dhiabhori ari mune slurry viscosity, iyo stucco jecha saizi yezviyo, uye nharaunda yekuomesa. Ndinoyeuka purojekiti ye turbine blade prototype apo goko rairamba richitsemuka panguva yekubvisa wakisi. Iyo wax pateni yaive yakakwana, dhizaini yaive yakanzwika, asi isu tainge tichirasikirwa ne30% yemateko. Nyaya yakanga isiri iyo yekutanga bhachi; kwaive kutonga kwemwando panguva yekuomeswa kwebhachi rekuchengetedza. Kuchinja kwemwaka kudiki kwatainge tisina kuripa zvizere. Izvi zvinhu zvisina kunaka, zvakatipoteredza zvinogona kukanganisa chirongwa. Chitoro chapfuura nemwaka yakakwana, seQingdao Qiangsenyuan Technology Co., Ltd.(QSY) nekufamba kwavo kwemakore makumi matatu, vangangove vakabika zvidzidzo izvozvo mumaitiro avo ekushanda. Havangovaka goko; vanogadzirisa microclimate.
Sarudzo yezvinhu inopindirana pano zvakare. Iwe haugone kungorova chero alloy mune chero shell system. Semuyenzaniso, kudururira yakakwira-tembiricha nickel-based alloys inoda rakasiyana goko refractory kuumbwa pane yakajairwa 316 simbi isina tsvina. Iko kupisa kwekuwedzera kusawirirana kunogona kukonzera kuparara kwegoko kana kupinda kwesimbi. Ndakaona zvidimbu zvichibuda zvine hutsinye, ganda repamhepo nekuti goko rakanga risina kugadzirirwa tembiricha yekudurura alloy. Iyo inzvimbo yakapusa yekutadza inoparadzanisa commodity caster kubva kune nyanzvi.
Apa ndipo panosangana vimbiso ye 'complex geometries' ichokwadi cheiyo yekutanga pasi. Iyo yakaoma yemukati chiteshi iwe yawakagadzira? Inongoshanda chete kana iyo ceramic core inogona kuiswa yakavimbika uye yobva yabviswa zvachose post-casting. Takambove nemuviri wevharuvhu une museve wemukati unotambudza. Kukanda kwacho kwaive kwakanaka, asi isu takashandisa yakawanda pane ultrasonic uye kemikari musimboti kubviswa pane pakukanda pachayo. A yakanaka Investment casting services mupi anozoratidza izvi kutanga, achikurudzira dhizaini tweaks kune epakati prints kana kukurukura mamwe machining marongero kubva pakutanga.
Alloys: Kwete Yese Simbi Yakagadzirwa Yakaenzana
Rondedzero yezvinyorwa-simbi yakakandwa, simbi, isina tsvina, cobalt-based, nickel-based-inotaridzika pawebhusaiti senge https://www.tsingtaocnc.com. Asi kubata navo hakuna chinhu kunze. Kukanda 17-4 PH isina tsvina kuti uwane iyo inodiwa H900 mamiriro muenzaniso wekare. Haisi kungonyungudika kwemakemikari; ndiko kutonhora kunodzorwa mushure mekudirwa uye kunotevera kupisa kupisa kutenderera. Tora mwero wekutonhodza usiri mu mold, uye kunaya kwemvura kuoma gare gare hakuzokupa ma mechanic properties aunoda. Chikamu chinogona kupfuudza kuongororwa kwekuona asi kukundikana mukuyedzwa kwekuneta.
Kushanda nema alloys akakosha senge cobalt-based Stellite kana Inconel akasiyana mumwe mutambo webhora. Ivo vanowanzo tsanangurwa zvakanyanya kupfeka kana corrosion resistance. Dambudziko nderokunyorova kwavo—kana kushaikwa kwahwo. Havayerere sealuminium. Iwe unoda yakakwira superheat, iyo inosimbisa goko, uye kazhinji inoda kukurumidza kudira mitengo kudzivirira kutonhora kusati kwasvika muzvikamu zvitete. Gating dhizaini inova yakakosha chose. Yakashata gating system pane yakajairwa kabhoni simbi chikamu inogona kungokupa iwe shrinkage mhango. Pa $500/kg cobalt alloy chikamu, kurasikirwa kunotyisa. Apa ndipo panowanikwa hunyanzvi hwesimbi, kwete chete kugona kwayo kukanda, kwakakosha.
Ini ndinofunga akawanda ekutsvaga maneja anorerutsa kukosha kweiyo foundry inonzwisisa zvechokwadi machining. QSY kutaura CNC machining tandem with casting haingori basa rekuwedzera kukosha; chiratidzo chekufunga kwakabatana. Ivo vanoziva kwekusiya masheya kuti ichene-chekuchekwa, kuti kukanda kushushikana kungakanganisa sei machining kukanganisa, uye ndeapi mapeji akakosha kubata kushivirira. Kukandira pedyo-mambure chimiro chikamu chisingachinjike imarara. Chitoro chakabatanidzwa chinodzidza kubva kumativi ese emaitiro.
Iyo Handoff: Kubva Kukandira kusvika Yakapedzwa Chikamu
Ichi ndicho chikamu chinofumura maitiro asina kunaka. Chikamu chakakandwa chakakwana chinogona kuparadzwa nehasha kuputika kuputika kana kucheka zvisina kunaka kwegeti system. Ndinorangarira bhechi resimbi isina simbi uko kusimba kwechitsiga chegedhi kwaive pazasi. Kuzvikanda kwacho kwaive kwakanzwika, asi iyo manual cutoff process yakanga yaburitsa zvakakwana kupisa kwenzvimbo kukanganisa iyo microstructure. Kugadzirisa kwaifamba kune abrasive waterjet kana inodzorwa-bhendi saw process ine kutonhora kwakaringana. Iro rondedzero yekupedzisa iyo isingaite iyo yekutengesa pitch, asi inouraya zvikamu.
Dimensional inspection imwe nzvimbo yezvimbambaira. Uri kubata nezvikamu zvakapfuura nemafuta ekutenderera kubva ~ 1500 ° C pasi kusvika kukamuri tembiricha. Vanofamba. Chinyorwa chekutanga chekuongorora chinyorwa (FAIR) chinosanganisira CMM data haigone kutaurirana kune zvakakosha zvikamu. Asi kunyange zvakadaro, unofanira kuziva zvauri kuyera. Datum zvimiro pane yekukanda dhizaini inofanirwa kuve inoshanda. Kutarisira nzvimbo yakakandwa kuti ive datum inoshanda kune yakasimba bore kushivirira kunowanzo kubvunza dambudziko. Dzimwe nguva, iwe unofanirwa kugadzira yekutanga datum, wozoongorora zvimwe zvinhu. Mupi anosundidzira kumashure pane zvisingaite zvekudhirowa callouts arikuitira nyasha.
Pakupedzisira, pane logistics yekuenderana. Vanogona here kuchengetedza iyo yakafanana simbi yekupisa kodhi yekugadzira inomhanya? Ivo vane traceability kubva kune ingot kune yakatumirwa chikamu? Kune maindasitiri akaita seoiri & gasi kana aerospace, izvi hazvisi zvekusarudza. Iyo inowedzera mutengo uye kuomarara, asi dhizaini yakashanda padanho iro, ingangove yakaivaka muhurongwa hwavo kwemakore, kwete sekufunga kwekupedzisira.
Kana Zvikashata (Uye Zvichadaro)
Kukundikana ndiye mudzidzisi akanaka. Pakutanga munguva yangu yekubata nekukanda, takava nekumhanya kwepombi dzimba mune duplex tsvina yakagadzira micro-cracking. Iyo chemistry yaive pa spec, maitiro aiita kunge asina kushanduka. Mushure mekuongorora kunodhura kunosanganisira kuongororwa kwerabhoritari yekunze, mupari wemhosva akatsvagirwa kutsvina diki mumidziyo yakadzokororwa yeceramic shell inokanganisa kutonhora kwenzvimbo. Mhinduro yaive yakasimba kudzora pane shell zvinhu sourcing uye yakagadziridzwa kupfura kutenderera. Pfungwa ndeyekuti, mupi ane ruzivo ane raibhurari yekutadza uku uye mhinduro dzadzo. Ivo vakadyara mumidziyo yekuongorora - spectrometers, ongororo yekupisa, radiographic michina - kuti isangowana dambudziko, asi nzwisisa zvikonzero zvayo.
Imwe gomba rinowanzoitika ndeye 'copy exact' nhema. Iwe unotumira chikamu chakakwana chemuenzaniso uye wokumbira quote kuti uidzokorore. Pasina maitiro ekutanga maparamendi - iwo chaiwo magomba, tembiricha yekudurura, gating dhizaini - uri kukumbira reverse engineering, kwete kubereka. Iyo quote inogona kunge yakaderera, asi kutenderera kwekusimudzira kuenderana nemuenzaniso kuchave kwakareba uye kunodhura. Nguva dzose zviri nani kutanga kubva pakudhinda uye kuita zvinodiwa.
Kuzvipeta: Izvo Zvisingabatike zveSevhisi
Saka, chii chauri kutenga chaizvo Investment casting services? Uri kutenga predictability. Uri kutenga mumwe wako aona mapeteni ewakisi achidonha, mateko anotsemuka, maaloyi asina kunaka, uye ane masisitimu ekudzivirira. Iwe uri kutenga mutongo kuti uzive kana dhizaini inokandwa se-iri, painoda tweak, uye painofanirwa kuitwa imwe nzira zvachose.
Hazvisi zvekuva nechoto chikuru kana marobhoti mazhinji. Icho chiri pamusoro pechirangaridzo chekubatana mune foundry. Kana kambani yakaita seQSY ichitaura pamusoro pemakore makumi matatu, iyo ndangariro ndiyo chaiyo asset. Zvinoreva kuti vangangodurura alloy yakavanzika yaunoda kare, vakagadzirisa iyo yakafanana geometry, uye vanoziva kuti ndeapi makona asingakwanise kutemwa. Iyo nhoroondo inoshandura zvakananga munjodzi yakaderera yepurojekiti yako, mashoma mainjiniya ekuchinja mainjiniya, uye mukana wepamusoro wekuti chikamu chekutanga chezvikamu chinogona kushandiswa, kwete zvimedu zvinotaridzika sedhirowa.
Pakupedzisira, basa rakanakisisa rinonzwa risina kuitika. Iwe unotumira kudhindwa, unowana quote, zvikamu zvinosvika nenguva, zvinokwana, zvinoshanda. Iko kuyerera kusina musono chiratidzo chemupi akafamba kupfuura kutengesa nzira yekuunza yakavimbika, yakagadziridzwa mhinduro. Ndiwo musiyano pakati pekutenga casting nekutenga mhedzisiro.
