The design and manufacture of cell phone shell stamping mold need to pay attention to what problems?

     The design and manufacture of stamping molds for cell phone casings requires attention to many of the following issues:

    Precision requirements
        The size of the cell phone shell is usually small and high precision requirements, the mold manufacturing precision should reach the micron level, to ensure that the stamped shell size is accurate, with a close fit.
        For example, the clearance between the convex and concave dies of the mold needs to be controlled within a very small range to avoid burrs or dimensional deviations.

    Material Selection
        Selection of high strength, high wear-resistant and good toughness of the mold material, such as high-quality alloy steel or carbide, to withstand frequent stamping operations and ensure the life of the mold.
        For example, for complex shapes and high output molds, higher hardness carbide may be chosen.

     Mold Structure
        Reasonable design of the die structure, including the shape of the convex and concave dies, and the precision and stability of the guiding mechanism, is required to ensure a smooth and precise stamping process.
        Optimize the nesting scheme to improve material utilization, reduce scrap generation and lower cost.
        Considering the shape characteristics of the cell phone shell, it may be necessary to use multi-station continuous stamping sampling method.

    Surface quality
        The surface of the mold should be finely treated, such as polishing, nitriding, etc., to ensure that the surface of the stamped case is smooth and scratch-free.
        Any tiny surface defects may affect the appearance quality of the cell phone shell.

    Cooling system
        Equipped with an effective cooling system to take away the heat generated during the stamping process in time, preventing the mold from overheating and causing deformation and wear.
        The layout and flow control of the cooling water channel need to be carefully designed.
