Die casting is a manufacturing process that can produce metal parts through the use of reusable molds, called dies. The die casting process involves the use of a furnace, metal, die casting machine, die and all the auxiliary equipment to keep all of them at the right temperature. The metal, typically a non-ferrous alloy such as aluminum or zinc or copper or magnesium, is melted in the furnace and then injected into the dies in the die casting machine. At the beginning of the cycle, dies require heating to the optimum temperature for the casting process, typically around 200ºC.
As the process takes place, molten alloys at temperatures of up to 700ºC will heat up the die.
If the die temperature is not appropriate, both at initial heating and following cooling phase of the die, troubles such as breaking, damage or malfunction of die and finished product may be caused.
In order to keep die always at right temperature, several Temperature Control Units (TCU’s) are used.
