Short cycle time leads to having a high temperature of the dies in the vacuum die casting.(a) True(b) FalseThis question was posed to me during an online interview.The origin of the question is Vacuum Die Casting in division Special Casting Techniques of Casting-Forming-Welding I

Answer»

The correct choice is (a) True

The explanation is: If the cycle time is very small, then the dies would readily get heated. Particularly in the sections such as sprues, or heavy sections of the casting, the temperature MAY be too HIGH. To MAINTAIN the required and uniform temperature, water is circulated through the HOT regions of the die.
