The abnormal situations of zinc die casting during production

    The abnormal situations of zinc die casting during production are these:
    Voids: in die casting filling process, because of presence the trapped gas, material impurities and shrinkage stress caused the emergence of holes.
    Flow liner: in the die casting process, because the mold temperature is lower or two different temperature materials mixed together to form flow liner.
    Bubble: in the die casting process, the mould temperature is too high and have voids, resulting in product surface bulge.
    Deformation: zinc die casting product thermal stress or when the demould, the uneven force caused the product shape to change.
    Lack of material: product demould is not smooth, some are adhesion on the mold.
    These conditions are related to the factors such as alloy material, die structure, product structure, feeding port, mould exhaust ect., which need to be solved together with these factors.
