Comparison of stampings and casting parts in Dalian

Although domestic stamping die makers have a great vision for automobile stamping parts, the imbalance in the development of domestic stamping parts is also worth watching. Although China's car production is amazing, many of them have also come from the investment and mass production of well-known foreign automobile brands.



At the same time, Dalian stamping parts as an important link to master the lifeline of the industry, the progress of its development has appeared regional imbalance. The stamping part is made by stamping under the premise of little material consumption. Its parts are light and rigid, and after the plastic deformation, the structure of the metal is improved, and the stamping strength is improved.



In stamping process, because the surface of the material is not damaged, it has good surface quality and smooth appearance. It provides a convenient condition for surface painting, electroplating, phosphating and other surface treatment. Stamping parts are thin metal hardware, that is, parts that can be processed by stamping, bending, stretching and so on. A general definition is that the parts with constant thickness in the process of processing are parts. Xinyulong stamping said corresponding casting parts, forging parts, machining parts, such as the car outside the Tieke sheet metal pieces, made of stainless steel kitchenware is some pieces of sheet metal.



The die used for stamping is generally specific. Sometimes a complex part needs several sets of moulds to form, and the mould has high precision and high technology requirement. It is a technology intensive product. Xinyulong stamping said only the larger production volume in stamping case, can fully reflect the advantages of stamping processing, to obtain better economic benefits.



Compared with the castings and forgings, the stamping parts have the characteristics of thin, uniform, light and strong. Punching can make other methods difficult to manufacture with reinforced bars, ribs, undulating or flanging parts to improve their rigidity. Because of the precision mold, the precision of the workpiece can reach the micron level, and the precision of repetition is high and the specifications are consistent, and the hole pit and the protruding table can be stamped.
