Automotive Molds Are Classified According To The Nature Of The Process

a. Blanking die: A die that separates the material along a closed or open profile. Such as blanking die, punching die, cutting die, incision die, cutting die, cutting die, etc.
b. Bending die: The die that causes sheet blank or other billet to bend and deform along a straight line (bending line), so as to obtain a certain Angle and shape of the workpiece.
c. Drawing die: It is a die that makes the blank of sheet metal into an open hollow part, or makes the hollow part further change its shape and size.
d. Forming die: The blank or semi-finished workpiece is directly copied and formed according to the shape of the convex and concave die, and the material itself only produces local plastic deformation of the die. Such as expansion die, shrink die, flaring die, undulating forming die, flanging die, shaping die, etc.
