Die Cast Mold
2023-07-25
Dies, or die cast molds, are made from alloy tool steel in at least two sections: the fixed die half (cover half), and the ejector die half. When the die casting machine closes, the two die halves are locked and held together by the machine’s hydraulic pressure. During the die casting process, molten metal is injected at high velocity into the mold (die) cavity to form a die cast part.
Cast tooling is maintained to ensure optimal quality and maximum tool life. The exact life of die cast tooling depends on part geometry and complexity, required tolerances, and most importantly – the type of metal cast. In general, Aluminum tooling can last approximately 100,000 shots, while Magnesium tooling lasts 200,000 – 300,000 shots.
