Die casting is a type of casting by forcing molten metal into steel molds using high pressure. In this process the pressure chamber (chamber) is connected to the die cavity permanently immersed in the molten metal.


Die casting is casting by forcing molten metal into a steel mold. The process of die casting techniques include:

  • The mold is sprayed with a lubricant and sealed. The lubricant helps control the die casting temperature and helps during release from casting.
  • The molded metal is then injected into the die under high pressure. High pressure makes the dough as precise and smooth as the dough.
  • Once the cavity is filled the temperature is maintained until the casting becomes solid (in this process the time is shortened using cooling water).
  • Then the die is opened and the injection molding is done at high speed so that the entire cavity is filled before there is a hardened part, although the design is very difficult to be able to fill a very thick part.
  • Often an operation is performed separating the cast from the remainder, using a trim die with a power press or a hydraulic press. This is so that the results are in accordance with the desired design.

The advantages of die casting itself are:

  • Holes can be made directly into the parts.
  • can make copper, zinc, and aluminum molds have heat transfer properties. Aluminum is a natural conductor of electrical goods.
  • Zinc, copper and aluminum are environmentally friendly materials and can easily be recycled after use. All aluminum alloys (360, 380, 383, and 413) are made from recycled materials.
  • More durable than plastic.
