Why die casting mold making will generate the stripe

    The reason of die casting mold making forming the stripe:
    At the front end of the liquid metal temperature is too low, meet incomplete fusion, a mark.
    The improvement of method:
    Check the wall thickness whether too thin (design and manufacturing), the thin area should be directly filling.
    Check the shape whether easy to filling; distance is too far, enclosed area (such as fin, convex), blocked the area, fillet region is too small and so are not easily filling. And pay attention to whether there is a rib point or cold spots.
    Shorten the filling time.
    Change the filling way of die casting mold making.
    Increase mold temperature
    Raise the temperature of molten metal.
    Check the composition of the alloy.
    Increasing the exhaust passage or add vacuum device, reduce the filling resistance.
