Die Casting Designs

Die cast manufacturing is a quick way to produce parts for many different industries. The main component other than the liquid alloys is the die molds themselves. The shapes of die moulds come in a variety of complexity, serving the needs of many different industries. A die cast has a maximum mould thickness of around 26 inches with a minimum thickness of 6 inches. To keep the moulds cool, cooling channels allow for the escape of steam, water, or oil to be released once the halves are closed. Properly designed moulds must be able to fill completely with liquid metal, solidify the alloy quickly, and allow the product to eject easily. Two die halves are used to create the mould. One half is the “cover”, and the other is the “ejector”. These two pieces are matched up to create a space where the “shot” chamber can be filled with the molten liquid alloy. The left over material or overflow is then trimmed and reused. Cavities of dies can vary from single, multiple, family, or units. Moulds with multiple cavities allow many parts to be made from one casting. The resulting cast is then trimmed revealing many single parts.
