How does the hardness and toughness of the mold material affect the quality of the terminal?

     The hardness and toughness of the mold material have a significant impact on the quality of the terminal:

   The effect of hardness:
    Dimensional accuracy: high hardness of the mold can better maintain its shape and size, so as to accurately shape the terminals during the stamping process and improve the dimensional accuracy of the terminals.
        For example, if the hardness of the mold is insufficient, it is easy to be deformed after a long period of stamping, resulting in deviation of the terminal dimensions.
    Surface quality: A hardened mold can make the surface of the terminal smoother, reducing burrs and imperfections.

        Softer molds may cause the surface of the terminal to be rough during stamping, affecting the appearance and electrical performance.
   The effect of toughness:
    Impact resistance: a die with good toughness can withstand impact loads during stamping, reducing the risk of die breakage or damage.
        If the mold toughness is poor, the impact of high-speed stamping may suddenly fracture, resulting in production interruption and product scrap.
    Die life: A die with good toughness can resist the expansion of fatigue cracks in long-term use, prolonging the service life of the die and thus producing high-quality terminals stably.
        On the contrary, low toughness of the mold is prone to premature failure, the need for frequent replacement, affecting production efficiency and consistency of terminal quality.
