China OEM tsika vacuum kukanda dhizaini giya dzimba dzesimbi alloy.
Vacuum Casting inodaidzwa zvakare kuti Negative Pressure Seal Casting, Yakaderedzwa Pressure Casting kana V process Casting. Vacuum pressure casting inoda kushandiswa kwemidziyo yekubvisa mweya kuburitsa mweya mukati memushonga wekukanda, wobva washandisa mutsauko wekumanikidza pakati pemukati nekunze kwe mold kuvhara firimu repurasitiki rinopisa pane pateni uye template. Iyo mold yekukanda ichave yakasimba zvekukwanisa kumira nesimbi yakanyungudutswa panguva yekukanda. Mushure mekuwana vacuum mold, zadza bhokisi rejecha nejecha rakaoma risina binder, uye wobva wavhara pamusoro pejecha nefirimu repurasitiki, rinoteverwa nevhayumu kuita kuti jecha rive rakasimba uye rakasimba. Mushure maizvozvi, bvisa mold, isa jecha cores, vhara mold kuti uite everthing kugadzirira kudururwa. Pakupedzisira, kukanda kunowanikwa mushure mokunge simbi yakanyungudutswa yatonhodzwa uye yasimbiswa.
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 vacuum 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.
