What are the limits on complex features that can be designed in a part to be die cast?
A. Intricate features and the most complex shapes are common to die castings, with the basic limitation being that a part feature must not prevent removal of the casting when the die halves are parted. With the use of a variety of core slides (or pulls), special features are cast in place, with the slides retracting to permit rapid ejection. Such moving die parts may require the use of a larger machine and rule out the use of a multiple-cavity die or unit die. These considerations will raise die casting production cost, plus a more complex die will add to die investment, but the result can be a net-shape casting with substantial cost reductions. The CWM Engineering Dept. should be consulted at the preliminary part design stage.
