Q:The difference between sheet metal and casting parts
Sheet metal refers to the metal sheet (which can be bent straight board, etc.) generally uniform thickness, can obtain the required parts by stamping, molding, welding, splicing and other processing methods.
Q:Why do cheap cars like stamping parts instead of casting parts?
We usually say that the stamping is usually refers to the cold stamping parts, for example, a piece of iron, wants to turn it into a fast food dish, it must design a set of mold, mold is working face plate shape, the pressure plate mold, it becomes you want the dishes, this is the cold stamping die stamping is the direct use of metal materials.Automobile stamping parts are mainly classified according to process, and can be divided into two major parts: separation process and forming process.
Q:Sealing test of casting parts 5
Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
Q:Domestic large steel castings factory which is better, recommend!
Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good.
Q:How to collect exothermic process of casting blank?
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:General aluminum alloy die casting or casting box and other parts,
Aluminum alloy die-casting parts or casting box and other parts of the threaded hole, in the case of processing conditions, it is best to use wire tapping or machine tool processing! Direct casting is not advocated.
Q:What is the difference between forging parts and casting parts?
The casting parts are low in cost and short in production period. Because the molten iron has good flow properties, complex shapes can be formed. But because there may be sand holes, pores, shrinkage holes and other defects, the quality is unstable, easy to produce many defects, mechanical properties are not forged well, thus affecting the service life.
Q:What is the difference between the casting drawing and the car work drawing?
Casting rough drawings generally no processing symbols, processing drawings indispensable is processing symbols!
Q:What is the ejection angle of the die casting (Tan Gang)?
Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angle
Q:How to get rid of casting sand inside casting parts?
Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!
