Hardware stamping is a process that uses a punch and a die to deform or break stainless steel, iron, aluminum, copper and other plates and other heterogeneous materials to a certain shape and size.
First, deep drawing: a stamping process that changes straight wool or process parts into hollow parts, or further changes the shape and size of hollow parts. When drawing, the hollow part is mainly formed by the material located outside the bottom of the male die flowing into the female die.
Second, trimming: a stamping process in which a metal stamping die is used to trim the edges of the forming process so that it has a certain diameter, a certain height, or a certain shape.
Third, punching: a stamping process that separates the waste material from the material or process piece along the closed contour to obtain the required hole in the material or workpiece.
Fourth, flanging: a stamping process that will be turned into a side short edge along the periphery of the outline curve.
Fifth, turning hole: a stamping process that turns the material into a side-up flange around the inner hole.
Sixth, blanking: a stamping process that separates materials along closed contours. The separated materials become workpieces or process parts, and most of them are planar.
Seventh, shaping: a stamping process that relies on the flow of materials and changes the shape and size of process parts to ensure the accuracy of the workpiece.
