Ha baenjiniere ba hlakisa silicon mold casting factory lits'ebeletso bakeng sa likarolo tsa tšepe tse phahameng, ha se feela likarolo tsa ho laela-li boloka botsitso ba dimensional tlas'a meroalo ea hydraulic ea 300 MPa, tsoelo-pele ea microstructure ka mor'a phekolo ea mocheso, le botšepehi ba holim'a metsi bo pholohang slurry e senyang lipompong tsa oli. Ke 'nete ea ts'ebetso ea ts'ebetso ea ts'ebetso e nepahetseng kajeno-eseng ho mamellana ha setšoantšo, empa ts'ebetso e lekantsoeng ts'ebeletso.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. e sebetsa e 'ngoe ea lisebelisoa tse' maloa tsa tlhahiso naheng ea China moo ho lahla ha silicon mold (mofuta o ikhethileng oa matsete a sebelisang likhetla tsa ceramic tse thehiloeng ho silika) o sebelisoa ka mokhoa o hlophisehileng ho lialloi tsa cobalt-nickel joalo ka AMS 5387 le T800. Re kentse lihlopha tse fetang 12,000 tsa khatello ea li-valve bakeng sa li-unit tsa taolo ea hydraulic ho tloha ka 2021-e 'ngoe le e' ngoe e hloka ± 0.05 mm mahloriso a mahlonoko, porosity e ka hare ea zero ho ASTM E192, le traceability e felletseng ho tloha ho alloy e tala ho isa tlalehong ea ho qetela ea CMM. Boemo boo ba ho tsitsa ha bo etsahale ka tšohanyetso. E etsahala ha ho lahla ho sa arohantsoe le machining, kalafo ea mocheso, kapa netefatso ea GD&T — mme ha sehlopha se seng le se seng se qala ka litifikeiti tsa thepa tse netefalitsoeng, eseng netefatso ea barekisi.
Liqeto tse tharo tsa tekheniki li arola ho lahla ha silicon mold ho tsoa ho ho lahla ho amohelehang-'me tsena li hlalosa seo bareki ba se lekang litekong tsa masimo:
- Taolo ea sebopeho sa likhetla: Li-binders tse tloaelehileng tsa silica sol li phunyeha ka holimo ho 1,100 ° C nakong ea ho tšela motsoako oa cobalt. QINGDAO QIANGSENYUAN e sebelisa silika e fetotsoeng ea colloidal + fused silica aggregate system e lekantsoeng ho 1,280 ° C - e netefalitsoeng ka tlhahlobo ea mocheso oa gravimetric sebakeng se seng le se seng sa khetla. Sena se felisa li-microfissures tseo hamorao li hlahang e le likheo tse bakang mokhathala ka har'a matlo a lisilindara tsa pompo.
- Taolo ea ho tiisa Directional: Bakeng sa matlo a silindara a pompo ea piston a nang le liphetoho tsa lebota la 42 mm, re tsamaisa li-castings ho 17 ° ho tloha holimo ka sebōping 'me re sebelisa lipoleiti tsa libaka tse hatsetseng likarolong tse teteaneng. X-ray tomography e netefatsa phallo ea lijo-thollo e tsamaellanang le li-vector tsa khatello ea maikutlo - e bohlokoa bakeng sa likarolo tsa AMS 5387 tse sebetsang ho 450 ° C.
- Ho notlela enfelopo ea sebopeho sa poso: Ho fapana le ho lahla lehlabathe, silicon mold castings e tšoara litekanyo tse tiileng joalo ka ha ho lahleloa—empa hafeela litumello tsa machining li entsoe ka paterone, eseng ha ho hakanngoa. Sehlopha sa rona se haha setoko sa 0.3-0.5 mm libakeng tse koalang ka thata, ebe se netefatsa ho khopama ha morao-machining ka ho tsamaisana le laser tracker likarolong tse kentsoeng. Bareki ba tlaleha 40% ho lahloa ho fokolang ha sehlooho sa pele ho li-winch center shaft rollers ka lebaka la sena.
Ba bang ba ka pheha khang ea hore machining a CNC a le mong a fana ka ho nepahala ho feta ho lahla. Empa seo se hloloheloa fisiks: ho lokisa "120 kg T800 alloy block" hore e be motheo oa pompo ea lik'hilograma tse 22 ho senya 82% ea litšenyehelo tsa thepa-'me ho hlahisa khatello ea maikutlo e senyang bophelo ba mokhathala ho kenya letsoho ka cyclic. Ho hlahisa hlobo ea silicon ho qala sebopeho se haufi-ufi. Ebe litsi tsa rona tse kopaneng tsa 5-axis li tlosa feela se hlokahalang-ho boloka sebopeho sa lijo-thollo, ho felisa mehato ea ho imolla khatello ea maikutlo, le ho fokotsa nako ea ho etella pele ka libeke tse 3.7 khahlano le mefuta e meng e sebelisitsoeng ka botlalo. OEM e le 'ngoe ea Amerika Leboea e fetotse mohala oa eona oa cobalt alloy nozzle ho ts'ebetso ena e nyalisitsoeng mme ea fokotsa litšenyehelo tsa yuniti ka 29% ha e ntse e atolosa bophelo ba ts'ebeletso ho tloha ho lihora tse 8,200 ho isa ho tse 14,600.
Seo bareki ba lulang ba se botsa - le seo re se arabang pele re se qotsa - ke mokhoa oa ho qoba mekhoa e meraro e atileng haholo ea ho hloleha ka har'a li-alloy silicon mold castings:
- Microshrinkage ka mateano: E rarollotsoe ke mohlala oa mocheso oa litsamaiso tsa li-gate le ho shebella mocheso oa nako ea sebele oa ho qhibiliha (± 1.5 ° C) nakong ea ho tšela-ha ho mekhelo.
- Ho se tsitsane ha bokahodimo: E atolosoa ka lipotoloho tse itirisang tsa likhetla tse lekantsoeng ho viscosity, pH, le kabo ea boholo ba karolo-eseng maikutlo a opareitara.
- Dimensional hoholeha ka har'a lihlopha: E thibetsoe ka ho boloka mekhoa e metle ea lisebelisoa tsa Invar tse tsitsitseng le ho netefatsa geometry e 'ngoe le e' ngoe ea khetla e nang le profilometry ea optical pre-assembly.
Ha re nke ho lahla e le mokhoa o ikemetseng. Mosebetsi o mong le o mong oa ho lahla hlobo oa silicon o ntse o hlahlojoa ka nako e tšoanang ea boenjiniere: Na karolo ea geometry e ntlafalitsoe bakeng sa ho tiea ka tsela? Na potoloho e boletsoeng ea kalafo ea mocheso ea AMS 5387 e lumellana le boholo ba lijo-thollo tse tiisitsoeng? Na qetello e hlokahalang ea Ra 0.4 μm e ka finyelloa ntle le ho sila ha bobeli ho ka bakang tšenyo e ka tlas'a lefatše? Tsena ha se lintlha tsa lethathamo. Ke lipuisano-tse ngotsoeng, tsa letsatsi, le tse khomaretsoeng taelong ea mosebetsi.
Ha u sheba pele, bothata ba 'nete ha se bokhoni-ke botebo ba setifikeiti. Selemong se tlang, QINGDAO QIANGSENYUAN e eketsa boholo ba ISO 13485 ho koahela likarolo tsa tlhahlobo ea masapo ea cobalt-chromium ea boemo ba bongaka, 'me e qala netefatso ea motho oa boraro ea ts'ebetso ea eona ea silicon khahlano le NADCAP AC7118 Rev. D bakeng sa mehala ea sefofane. Hobaneng? Hobane basebelisi ha ba sa amohela "e sebelitse lekhetlo la ho qetela." Ba batla ho pheta-pheta ho tlalehiloeng - ho pholletsa le lisebelisoa, li-geometri, le mabelo a tlhahiso. Ha hao silicon mold casting factory e ka fana ka likarolo tsa pompo tsa AMS 5387 tse nang le ts'ebetso e feletseng ea metallurgical, likarolo tsa bohlokoa tse tiisitsoeng ke CMM, le litlaleho tsa ho se lumellane le zero ka likhoeli tse 18 tse latellanang, u khaotsa ho ba morekisi. U fetoha motheo.
