- First, deep drawing: a stamping process in which straight wool or process parts are turned into hollow parts, or the hollow parts are further changed in shape and size. During deep drawing, the hollow part is mainly formed by the material located outside the bottom of the convex die flowing into the concave die.
- Second, trimming: a stamping process that uses a metal stamping die to trim the edge of the forming process to make it have a certain diameter, a certain height or a certain shape.
- Third, punching: a punching process that separates the waste from the material or process part along the closed contour, and obtains the required hole in the material or workpiece.
- Fourth, flanging: A stamping process in which a short side is turned into a short side along the contour curve.
- Fifth, hole turning: a punching process that turns the material into a side flange around the inner hole.
- Sixth, blanking: a stamping process that separates materials along a closed contour. The separated materials become workpieces or process parts, most of which are flat.
- Seventh, shaping: relying on the flow of materials, a small amount of changes in the shape and size of the process parts to ensure the accuracy of the workpiece is a stamping process.
