Vacuum casting simbi dhizaini giya dzimba dzemotokari dzekutakura dzemisika yeRussia ine CNC machining uye netsika-yakagadzirwa masevhisi. Cast alloy steel v process castings zvinoreva zvikamu zvekukanda zvinogadzirwa nevacuum casting processnezvinhu zvecast alloy steel.
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.
Zvakanakira Vacuum Casting Maitiro
1) Iyo vacuum castings ine yakakwirira dimensional kurongeka, yakajeka ratidziro uye yakatsetseka nzvimbo.
Nekuti pamusoro peiyo modhi yakafukidzwa nefirimu repurasitiki, hapana chikonzero chekudedera kana kugogodza kana uchidhonza mold. Kusveta uye kudzvinyirira kwakashata kunoita kuti jecha rekuumbwa ribatane, uye kuoma kwejecha mold yakakwirira uye yakafanana. Pasi pekupisa kwesimbi yakanyungudutswa, gomba racho harisi nyore kukanganisa. Uyezve, kuvepo kwekumanikidza kwakashata kunobatsira pakuzadzwa kwakazara kwesimbi yakanyungudutswa mumuenzaniso. The pamusoro roughness pamusoro V process castings inogona kusvika Ra = 25 ~ 2.5μm. Iyo dimensional kushivirira nhanho yekukanda inogona kusvika CT5 ~ CT7. Chitarisiko chemhando yeasina kunaka pressure castings yakanaka, uye mhando yemukati yakavimbika.
2) Iko hakuna zvisungo, mvura uye zvinowedzera mujecha rekuumba, izvo zvinoita kuti jecha rive nyore.
3) Zviri nyore kuchenesa iyovacuum castings. Magasi mashoma anokuvadza anogadzirwa panguva yekukanda.
4) Iyo vacuum castings inogona kushandiswa pane dzakasiyana siyana maindasitiri. Inogona kushandiswa kune imwechete-chidimbu diki kugadzirwa kwebatch pamwe nekugadzirwa kwakawanda, kunyanya mahombe uye epakati-saizi castings uye dzakatetepa-madziro castings anonyanya kukodzera pakukanda vacuum.
