Q:Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you
Service performance: heat conductivity, friction reduction, shock absorption, heat resistance and corrosion resistanceTo compare these properties, it depends on the specific material, structure, and use of the parts. Otherwise, there is no comparisonS
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:our factory now produces steel castings in the use of polishing directly after spraying processing, but the powder sprayed 15But the spray powder touched off what is the reason we are not very strict requirements not only need to peel off bubbles can also, because our products are steel castings so we use steam hole sludge put on. Do not know if this spray treatment has no effect to thank friends with us!
Cast iron has not been done, if it is iron, then in the spray before going through strict pretreatment, the surface can not have a little oil dust
Q:What method of casting does not rust? I think the sample is like oil
The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
Q:In the design of casting steps and precautions, for casting design, we have what experience?.
(3) to prevent generating white grey cast iron, in addition to taking measures from the process, must make the wall thickness is not too thin (some sources indicate that the corner wall thickness above 15mm, metal type casting must be in the corner, for Aluminum Alloy, magnesium alloy casting casting casting Create fillet should not be less than 3-4m, for casting round cast iron, copper alloy mould casting can see table 1.1-32 selection; (5) because of the metal and the core without let, for the convenience of the casting is taken out and the draw out type, slope casting casting should be suitably large than sand casting metal casting. General 30%-50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface position, where the cooling and contraction and metal surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal castings the type should be given greater inclination, all kinds of metal type alloy casting casting casting.
Q:What are the casting parts processing engineering?
At present, casting processing, according to metal classification, divided into cast iron, cast steel, casting non-ferrous metal.
Q:Casting parts have poor surface finish. What sand is used to make them?
Now resin sand, coated sand and other processes are also very good surface.
Q:Heat treatment process and purpose of casting parts
Methods: artificial aging or natural aging (also called normalization) treatment.Artificial aging: heating to 2-3 Baidu, it is best to apply mechanical vibration, and maintain a period of time.
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 parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?
If it is not directly cast hole hole, later processing, large pores may be directly cast out,
