Thermal Stress Model Predicts Die Life - Tests conducted by CDA over the past several years show that there are two secrets to achieving acceptable die life when die-casting copper motor rotors: Use a nickel-base superalloy as the die material. Preheat the die to approximately 650 C (1202 F) before injecting molten copper, and maintain that temperature between shots. MORE >>
