Those who aren’t involved in the industry typically have a generic understanding of die casting. For many, it might only go as far as being familiar with the key terminology, such as knowing that the mold is referred to as a die.
Expanding on this concept would explain that the die acts as variable element, and is injected with molten metal. This process is generally done under high pressure, exerting the force on the die. The molten metal can be injected two different ways, the difference between the two is referred to as Hot and Cold Chamber processes.
