Die Casting Tooling: 4 Types of Dies. Dies, or more appropriately termed as die cast tooling, are one of the most essential parts when it comes to die casting. Naturally, you cannot make a certain alloy component without creating the perfect mold – which is why dies are also often called die casting molds. The actual creation of dies begins with the blueprint of the piece or pieces that is to be developed. This is not as easy as it sounds. Very stringent measures are undertaken to make sure that the dies fit every configuration of the overall design. Often the blueprints, the die casting tooling and the corresponding pieces that come from the first two have to be worked over until the perfect pieces are achieved. Only then can mass production of the said pieces can continue.
As such there are 4 known existing types, and these are: single cavity die, multiple cavity die, unit die and the combo die or the combination die.
Single cavity die casting mold, as the name implies, refers to mold that is often used in the creation of a single component. Usually, the very large pieces of metal works are created from single cavity die to ensure that the pieces are “flawless.” On the other hand, multiple cavity die refers to molds that have smaller components but are identical in design. This type of die is more economical when it comes to mass production of smaller pieces.
Unit dies are best for the creation of different pieces that would be fitted to create one larger piece, or unit. This is best for the medium to small pieces as well. Lastly, there is the combo die. The combo die can be a mix of two of the aforementioned dies above or all three. This is great for assembly line production.
