Sheet metal processing is the key technology that sheet metal technical staff need to grasp, and it is also an important process of sheet metal product forming. Sheet metal processing is including the traditional cutting, blanking processing, bending forming and other methods and process parameters, but also includes a variety of cold stamping die structure and process parameters, a variety of equipment working principle and manipulation methods, but also includes new stamping technology and new technology. Part sheet metal processing is called sheet metal processing.
Stamping die is in cold stamping processing, the material (metal or non-metal) processing into parts (or semi-finished products) of a special process equipment, known as cold stamping die (commonly known as cold stamping die). Stamping, is at room temperature, using the mold installed in the press to exert pressure on the material, so that it produces separation or plastic deformation, so as to obtain the required parts of a pressure processing method.
Precision casting is a general term for the process of obtaining castings of precise dimensions. Compared with the traditional sand casting process, the casting size obtained by precision casting is more accurate and the surface finish is better. It includes: investment casting, ceramic mold casting, metal mold casting, pressure casting, lost mold casting.Precision casting is also called lost wax casting, its products are precise, complex, close to the final shape of the parts, can be used directly without processing or little processing, is a near-net shape of advanced technology.
