What is the effect of die clearance size on the quality of high-speed stamped precision terminals?

     The size of the mold clearance has a significant impact on the quality of high-speed stamping precision terminals, which is mainly reflected in the following aspects:
    Dimensional accuracy of stamped parts
        Gap is too small: the material in the stamping process is subject to extrusion is too large, easy to lead to the size of the terminal is large, and there may even be excessive compression of the material is generated by the phenomenon of “stacked material”, affecting the dimensional accuracy.
        Excessive gap: the material is subjected to increased stretching effect, which is likely to make the terminal size is small, and may lead to the irregular shape of the stamped part, the edge is not neat.

    Section quality of stamped parts
        Too small a gap: In the stamping process, the material is subjected to strong shear action, which will produce thicker, non-smooth burrs, affecting the appearance and usability of the terminals.
        Excessive gap: the material is prone to produce tear-like rough section when breaking, and the burrs are larger and uneven.
    The life of the mold
        Too small a gap: the friction between the mold and the material increases, the mold wear increases, shortening the service life of the mold.

        Too large a gap: the impact load on the mold in the stamping process increases, which also accelerates the damage of the mold.
    Flatness of stamped parts
        Inappropriate clearance: It may lead to bending, warping and other deformation of the terminal after stamping, affecting its flatness.
    Material utilization
        Unreasonable clearance: It may increase the generation of scrap, reduce the utilization rate of materials, and increase production costs.
