Advantages of permanent mould casting

Permanent mould casting is a process makes use of a reusable metal mould that made from metal. This process involves pouring molten metal into a mould where cools and solidifies after that mould is opened, casting is removed and mould is reused. Let us have a deep insight into the advantages provided by using this casting process. 

Advantages of permanent mould casting : 

  • Close dimensional tolerance can be obtained. 
  • This process is economical for large scale production as the labour involved in the mould preparation is reduced. 
  • Produce a very good surface finish of the order of 4 microns.
  • Better appearance.
  • This process produces a fine-grained casting with superior mechanical properties because of the metallic mould used.
  • Small cored holes may be produced as compared to sand casting.
  • Inserts can be readily cast in place. 
  • Increases repeatability of casting.
  • Finer grain structure can be obtained.
  • High volume production runs.
  • Less expensive than investment and die casting.
