Die Casting

Die casting is a casting process for series or mass production. 

In die casting, the liquid melt is pressed under high pressure and at a very high die filling speed into a die casting mould, where it then solidifies. 
The special feature of die casting is the permanent mould, in which no model is used. For a series of identical components, for example, mould production is only required once, although it is subject to higher production costs. However, a higher output is achieved in this way.
Die casting competes with injection moulding with plastics. 

The most frequently used materials for die casting are

  • Aluminium (die-cast aluminium)
  • Zinc (zinc die casting)
  • Magnesium (magnesium die casting)
  • Copper alloys (brass die casting)
  • Tin (die-cast tin)
