A. Blanking die to separate the material from the closed or open contour line.Such as blanking die, punching die, cutting die, cutting die, cutting edge die, cutting die etc.
B. Bending die causes the blank or other blank to produce bending deformation along the straight line (bending line) to obtain the mold of the workpiece with certain Angle and shape.
C. drawing die is to make a hollow part of the blank, or to further change the shape and size of the mould.
D. The forming mode is to reproduce the blank or semi-finished workpiece directly by the shape of the drawing and the shape of the die, while the material itself only produces the local plastic deformation mold.Such as expanding die, shrinkage cavity die, expanding die, rolling forming die, flanging die, shaping die, etc.
E. The riveting mode is to use external forces to connect the participating parts in a certain order and way, and to form a whole.
