Low pressure diecasting is the process in which a ceramic tube is connected to a die & extends to a molten metal furnace below.  Air is introduced into the sealed pressurised furnace which forces the metal up slowly through the stalk tube & into the die cavity.  Once the component has solidified, air pressure is released which allows residual molten metal to flow back into the furnace to be reused.

Some of the main advantages of this process are:

  • Automation of process improving repeatability
  • High casting yields
  • No runners or feeders improve processing time
  • Casting integrity is enhanced due to reduced turbulence when filling
  • The sealed furnace reduces atmospheric reaction with the melt
