15-year precision mould making

    What is the role of core pin in the mold? YiZe to tell you.
    The concept of core pin:
    Die casting mould core is the most prone to problems in the production process, in order to solve this problem, the mould core was transformed into detachable single core parts, it is called the core pin. It is used to make the hole or the irregular shape of the die casting parts in the casting process, which belong to the parts of the mold.
Features: anti abrasion, corrosion resistance, high precision, high surface brightness, suitable for the export precision injection mold!
    The role of core pin in the mold:
    Mold in the use process, if the core position there is a problem, only need to replace the bad core pins, do not need to scrap the entire mold, so as to save the cost.
    Core pin with cooling hole:
    Use of SKD61 materials without heat treatment. First make the cooling hole then heat treatment. The core pin with cooling hole can greatly improve the service life of the product.
    Core pin without cooling hole:
    To make use of heat treatment materials, That is can be done the surface treatment after the appearance of processing and inspection, no need to heat treatment again. This can reduce the residual stress in heat treatment, but also can improve the product's concentric degree and shorten the delivery cycle.
