China OEM tsika yevacuum yekukanda masipari enjanji yekutakura mota dzeCr-Mo alloy simbi ine kupisa kupisa, kurapwa kwepamusoro uye.CNC machining sevhisi.
Vacuum Casting inodaidzwa zvakare kuti Negative Pressure Seal Casting, Yakaderedzwa Pressure Casting kanaV 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.

Ndezvipi Zvakanakira Vacuum Casting?
1) Thevacuum castingsiva nehupamhi hwehupamhi hwechokwadi, yakajeka rondedzero uye yakatsetseka pamusoro.
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.
Ndeapi Masimbi uye Alloys Anogona Kukandwa neVacuum Casting?
• Grey Cast Iron, Ductile Cast Iron
• Carbon Steel: Low carbon, medium carbon and high carbon steel
•Cast Steel Alloys: Yakaderera alloy simbi, yakakwirira alloy simbi, yakakosha alloy simbi
• Aluminium uye alloys avo
• Brass & Copper.
Kukandwa (cast steel) zvinoreva simbi inoshandiswa kugadzira simbi. Simbi yakakandwa inofanira kushandiswa kana simba rekukanda richikwira uye kushandiswa kwesimbi yekukanda hakugone kuzadzisa zvinodiwa. Nekudaro, iyo fluidity yesimbi yakanyungudutswa yesimbi yakanyungudutswa haina kunaka seye simbi yakakandwa, saka ukobvu hwekudurura chimiro hachifanirwe kuve chidiki uye chimiro hachifanirwe kunge chakaoma. Kana iyo silicon yemukati ichidzorwa pamuganho wepamusoro, iyo fluidity yesimbi yakanyungudutswa inogona kuvandudzwa.Simbi yakakandwa inogona kukamurwa kuita simbi yakakandwa uye yakakandwa kabhoni simbi zvinoenderana nemakemikari ayo, uye inogona zvakare kukamurwa kuita simbi yechishandiso simbi, yakakandwa simbi yakakosha, huinjiniya nekukandira kwechimiro uye kukanda alloy simbi zvinoenderana nehunhu hwayo.
Cast alloy simbi inogona kupatsanurwa kuita yakaderera alloy simbi (iyo yakazara alloy zvinhu ishoma pane kana kuenzana ne5%), yakakandwa alloy simbi (iyo yakazara alloy zvinhu i5% kusvika 10%) uye yakakanda yakakwira alloy simbi (iyo yakazara alloy. zvinhu zvakakura kudarika kana kuenzana 10%).
