Die Casting processes are often described as the shortest route between raw material and finished product.
Pressure Die casting
 
  • Molten metal is injected under high pressure into die.
  • Reusable hardened metal dies, water or oil cooled.
  Hot Chamber Pressure Die Casting
 
  • Hot chamber / Plunger machines are used.
  • Used widely for Zinc & Magnesium.
  • Low melting temperature alloys.
  • High rate of productivity.
  Cold Chamber Pressure Die Casting
 
  • Cold chamber machines are used.
  • Used widely for Aluminum, Brass & Magnesium alloys.
  • High melting temperature alloys.
  • High rate of productivity.
Gravity Die casting
 
  • Molten metal is poured into a metal molds under a gravity head.
  • Cores can be metal, sand, sand shell or other material.
  • Also known as Permanent Mold casting in the USA, Canada & various other countries.
Special characteristics of Die Casting
 
  • An efficient, economical process offering a broader range of shapes and components.
  • High production rates.
  • High dimensional accuracy and consistency.
  • High integrity castings.
  • Extremely good surface finish obtained.
  • Complex shapes can be cast.
  • Long or short runs can be accommodated.
  • Machining can be eliminated in most cases. Minimum secondary operations required.
