Vacuum casting simbi dhizaini giya dzimba dzemotokari dzekutakura dzine CNC machining uye netsika-yakagadzirwa masevhisi. Cast alloy steel v process castings zvinoreva zvikamu zvekukanda zvinogadzirwa nevacuum casting processnezvinhu zvecast alloy steel.Chromium-molybdenum cast simbi inoshandiswa zvakanyanya muminda yemaindasitiri ine yakakwira michina zvivakwa. Kuwedzerwa kwe molybdenum kune chromium simbi kunogona kuwedzera kusimba kwesimbi yekukandira pasina kuve nekukanganisa kwakakosha pakusimba kwekusimba kwesimbi yakakandwa. Chromium-molybdenum cast simbi ine yakanaka kwazvo yakakwira tembiricha kuita uye inokambaira kuramba. Mushure mekudzima uye kudzikisira kana kujaira kupisa kurapwa, chromium-molybdenum yakakandwa simbi inogona kuwana yakanakisa mechaniki zvivakwa. Molybdenum inogona kuvandudza kuoma kwesimbi yakakandwa uye kuderedza hasha brittleness yesimbi yakakandwa. Chromium-molybdenum cast steel inoshandiswa kune yakakura-chikamu castings uye simbi castings inoda kuomeswa kwakadzama.
Vacuum molding casting, inonziwo negative pressure molding method, vacuum sealing molding method, kana V maitiro kwenguva pfupi. Urwu rudzi rutsva rwemhando yekuenzanisira yemuviri. Iyo yakaipa yekumanikidza yekuumba nzira inoshandisa kudzvanywa musiyano pakati pemukati nekunze kwemuumbi kusungira yakaoma uye yakasununguka jecha zvidimbu pamwechete kuti uwane mold ine chimwe chimiro chinodiwa uye imwe simba.
Vacuum casting inobvumira kugadzirwa kwezvimedu zvidiki zvemhando yepamusoro-soro mumhando dzakasiyana dze polyurethane resin inodzokorora kushanda kweinjiniya mapurasitiki pasina mutengo wakakura wemidziyo yakaoma ine chekuita nekuumba jekiseni. Maitiro acho anotanga nekugadzira mold nekuputira tenzi modhi mune maviri-chikamu liquid silicone rubber. Vacuum inobva yaiswa kubvisa chero mweya wakavharirwa, uye inoporeswa muchoto. Master modhi inogona kubva kune akati wandei e3D kudhinda matekinoroji anosanganisira stereolithography. Kana iyo silicone yarapwa, mold inochekwa yakavhurika kuti iite mutsara wekupatsanurwa, iyo master modhi inobviswa iyo inosiya mhango ye mold ichinyatso dzokorora iyo master modhi. Kuti uite chikamu, zvikamu zve mold zvinodzoserwa pamwe chete, zvakachengetedzwa, pre-kupisa uye kuiswa muvacuum casting system chamber. Zviviri kana zvitatu chikamu resin inoyerwa, pigment inowedzerwa kana ichidikanwa uye zvikamu zve resin zvinoiswa mune otomatiki musanganiswa wevacuum casting system. Panguva ino, iyo vacuum casting system inotora nzira yekusanganisa zvinhu zveresin uye vacuum yekukanda modhi. Kana izvi zvapera, kukanda kunorapwa. Mushure mekurapa, zvikamu zve mold zvinogona kuparadzaniswa uye chikamu chacho chakabviswa. Chasara ndechaJehovhakukanda zvikamukuti ichekwe uye ipedzwe sezvinodiwa.
