1,

2,The basic process of stamping
1. Blanca: Using a die to separate the sheet metal from the blank in a closed contour

Using punching to obtain a certain shape of the workpiece or billet

Separate the material inside the stamping blank with a closed contour to obtain perforated parts
2. Cutting: Separate parts or blanks from the sheet metal according to unclosed contour lines
3. Bending: Bend the sheet or profile into a certain angle using a punching die

4. Graficum profundum

Forming the sheet metal into hollow parts while keeping the thickness basically unchanged
5. Flanging

Using the method of expanding holes on flat billets with holes, the plate is flipped into a straight edge along a certain curvature
