The phases of die casting

  1. The melt is poured into the piston.
  2. The liquid metal is pressed under high pressure into the mold.
  3. The metal solidifies in the mold.
  4. The die-cast part is ejected. 


The diecasting process

Diecasting is an industrial casting process for manufacturing cast parts of aluminum, zinc, magnesium or brass. The molten metal is pressed under high pressure into the die where it hardens and is then automatically ejected. A diecasting die can contain several cavities. Depending on the die, series ranging from approximately 300 to 400,000 molded parts can be produced due to the high output of the dies. Diecasting allows parts to be manufactured with very thin walls and smooth surfaces and edges. Due to the high strength, very good dimensional accuracy and reproducibility, diecasting is the optimum casting procedure for complex components and demanding applications, both in terms of quality and economy. 

Advantages of diecasting:

  • Suitable for thin-walled, complex component geometries
  • High level of dimensional accuracy with high process stability
  • Favorable strength
  • Smooth surfaces and edges
  • Short casting cycles
  • Very economical
