 In the electronic stamping factory in the quality requirements for the production of metal stamping parts it is very strict. Therefore, we must strictly control the

shape and size of stamping parts:
    The first is the curved pieces of requirements:
1) bending member should be symmetrical shape, the bending radius is not less than the minimum bend radius of the material allows.
2) The curved edge is too short not easy to shape, it should make a straight portion H bending edge> 2δ. If you require H is very short, we need to set aside an

adequate margin to increase H, bend well and then cut the increase in metal.
3) When the bent foraminous member, in order to avoid deformation of the hole.
Followed by the drawing part of requirements:
4) metal stampings shape should be simple, symmetry, depth should not be too large. So that the least number of drawing, easily molded.
 5) radius of metal stamping parts without increasing the processing sequence in the case. Otherwise it will increase the number of drawing and shaping work, also

increased the number of mold, and prone to waste and cost.
    Metal stamping die used is the use of repression stripper plate or fixed discharge board, depending on the size of the discharge force, wherein the material

thickness of the material is the primary consideration. With the mold with an elastic element elastic enhancements (such as rectangular spring), urging force unloading

stripper plate greatly enhanced. Under the current circumstances, the use of fixed stripper plate material when the material thickness using the urging discharge board

at 2mm less than 2mm more close to reality. The punch of the mold material material thickness of 1mm, and therefore can suppress discharge board. Metal stamping is

applied to the mold by the press and on the plate, strip, pipe and profiles and other external forces, thus producing plastic deformation or separation, to obtain the

desired shape and size of the workpiece (stamping) of forming methods.
