Stamping (also known as stamping) is the process of placing a blank or coil shape of flat metal into a stamping machine where tool and die surfaces form the metal into a net shape. Stamping includes various manufacturing processes for forming sheet metal, such as using mechanical stamping or stamping , blanking, embossing, bending, flanging and embossing. This can be a single-stage operation in which each stroke of the stamping produces the desired form of the sheet metal part, or can occur through a series of stages. The The process is usually performed on sheet metal, but can also be used on other materials such as polystyrene.
Deep drawing is a sheet metal forming process in which the sheet metal blank is drawn radially into a forming die by the mechanical action of a punch. Therefore, it is a shape transformation process with material retention. When drawn When the depth of the part exceeds its diameter, the process is considered "deep" drawing. This is achieved through a series of dies. Due to the retention properties of the material, the flange area (sheet metal in the area of ​​the die shoulder) undergoes Radial tensile stress and tangential compressive stress. These compressive stresses cause the flange to wrinkle. Wrinkling can be prevented by using a blank holder, which is used to facilitate the control of material flow into the die radius.
