- Q: Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?
- Casting, do not need to provide a rough casting foundry drawings, according to your chart will put foot margin in the processing needs of the surface, the rest of the size can be found according to the mechanical design manual and manual casting. General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.
- Q: The casting sand is going on
- 2, causes(1) sand mold (core) strength is not high, when the box a little reason will fall off.(2) the strength of sand mould (core) is not high, it can not stand the erosion of molten steel.(3) box sand mould (core) crush.(4) high strength under high temperature, warpage, deformation and protuberance into the cast steel under the action of high temperature molten steel.(5) the floating sand in the air hole of the sand mold falls, especially when the floating sand falls in the casting, and the floating sand on the surface of the sand mold is easy to fall through the air vent.(6) when the box is closed, the surface of the mold cavity and the surface of the sand core are not cleaned, and the sand (core) surface has floating sand and so on.
- Q: How much is the amount of electrophoretic paint per square meter used in the casting?
- In general, when the final thickness of 15-20 microns, cathode electrophoresis paint can be coated per kilogram of 6-8 square meters, the current general cathode electrophoresis paint for the price of 22 yuan / kg, so the cathodic electrophoresis electrophoresis paint cost at 4 yuan / square meters.
- Q: What should I pay attention to when designing a casting structure?
- (2) in the prevention of metal mold casting misrun and cold partition should pay attention to the following problems: the structure of A casting thickness should be appropriate not too thin, especially when casting size when not too thin; the B should avoid a big level, because it makes the liquid metal in the casting. Rise slowly, and the air contact surface, easy oxidation, and because the metal type liquid metal heat quickly, quickly lose liquidity, easy to cause misrun and cold lap, slag and other defects; C casting shape should be streamlined to avoid sharp corners and has sharp change connection structure in order to facilitate the flow of liquid metal. 2 in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.
- Q: Does anyone know how to make precise casting parts for aerospace or manufacturers of single and small quantities of automotive parts and components, mainly in Beijing, Tianjin and Tangshan?
- List of China's military enterprises list of ten major military groupsChina Nuclear Industry Construction Group CorporationChina Aerospace Science and Technology CorporationChina Aerospace Science and Engineering CorporationChina Aviation Industry CorporationChina Aviation Industry Corporation IiChina State Shipbuilding CorporationcsicChina North Industries Group CorporationChina South Industries Group CorporationChina National Nuclear CorporationKey military enterprisesShipbuilding industry:China State Shipbuilding Corporation (South ship group), (China Shipping Group)China Shipbuilding Industry Corp (North Ship group), (China Shipbuilding Industry)Guangzhou Shipyard International Limited by Share Ltd (GSI)Jiangnan Heavy Industry Limited by Share Ltd (Jiangnan Heavy Industry)Nuclear industry:China National Nuclear Corporation (CNNC)China Nuclear Industry Construction Group Corporation
- Q: Cause of choking of casting parts
- Choke fire is the process of pouring a large number of gases can not be discharged smoothly, boiling in the metal liquid, resulting in a large number of castings in the pores, and even incomplete casting defects
- Q: We are small castings, the need for surface treatment of shot blasting machine, about how much?
- according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation
- Q: When there is no flaw detection for large casting parts, is there any crack inside?
- According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
- Q: Is 316 casting better than 304 casting?
- The degree of difficulty in the process of casting depends mainly on the structure, precision requirements, and hardness of the casting. It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
- Q: Shandong foundry, casting small pieces of precision casting
- Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,
