Method for preheating a metal casting die and apparatus for carrying out the method

摘要

Method for heating a metal die-casting die by means of induction, in which the die-casting die is preheated only into the vicinity of the working temperature by means of induction and the operating temperature is achieved subsequently in the production process itself by the die-casting operation. To carry out the method, an induction coil is either laid externally around the die or is laid in the cavity of the die.
