- Q:In theory, which is more expensive, forging parts or casting parts?
- Compared with the price, the product with the same simple structure eliminates the material factorsThe forgings must be more expensive
- Q:Shandong foundry, casting small pieces of precision casting
- Dongying Huayang precision casting factory, the smallest to do 2G pieces.
- Q:Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you
- The performance is too extensive, I think the following several people all fall into the erroneous zone directly, the performance includes a series of aspects:Mechanical properties: tensile strength, yield strength, elongation and contraction ratio of section and impact toughness after etc.
- Q:Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
- Our country has a national standard for casting tolerance levels. This national standard applies to you in malleable iron, grey cast iron, and ductile iron.
- Q:What are the factors affecting the machining process of the casting material and structure?
- As for the metallographic structure, usually the finished products after casting are treated by heat treatment. The mechanical properties of the carbon steel after heat treatment (quenching and tempering) are detected. The stainless steels are treated by heat treatment (solid solution, etc.) and the metallographic structure is analyzedThere is a lot of talk and a bit of confusionIf you have a specific brand, you can search for Baidu or buy tools
- Q:Why do casting parts have air holes?
- There are many reasons for casting porosity, mainly due to:1. smelting process is unreasonable, metal liquid absorbs more gas;2. the gas in the mold invades the metal liquid;3. from the mold is more water brush, core dry;4. the casting has poor ventilation;5. ladle tools are not dry.Wait。
- Q:Where is the precision casting factory?
- The National Precision Casting Factory is generally distributed in Shandong, Ji'nan, Jiangsu, Wuxi, Changzhou, Zhejiang, Guangdong, Panyu, Dongguan.The above are only the main distribution, many of Shandong are made supercharger, and Guangdong to jewelry industry based.
- Q:What is the difference between casting and stamping parts?
- Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute.
- Q:What should I pay attention to when designing a casting structure?
- The basic structure of unit 3 in the design of metal casting casting and its parameters are selected, usually should also pay attention to: (1) because of the metal type heat quickly, so the metal type casting minimum wall thickness should be bigger than the sand casting casting casting; (2) the inner wall of the internal ribs and the thickness of a should be connected the outer wall thickness of 0.6 to 0.7, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage; (3) to prevent generating white grey cast iron, in addition to taking measures in the process, must make the wall thickness is not too thin (some information that cast fillet at the corner of the wall thickness of 15mm or more, with metal casting casting must be in the corner, for Aluminum Alloy, metal casting magnesium alloy castings shall not be less than 3 ~ 4m; (4) because of the metal type and the core that, for To facilitate the extraction of castings and casting out type, slope casting should be suitably large than sand casting metal casting, the general should be 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 of the metal type the 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 casting type should be given greater inclination.
- Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
- Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
