  1. Material Science Die Casting Developments in dies Annamalai Industrial Engineering

  2. Die casting process • Molten metal is injected under high pressure into a steel mold (die). • Rated in “Clamping tons” • Amount of pressure they can exert on the die • Capacity 400 tons to 4000 tons

  3. Alloys • Aluminum & magnesium • Substitute for ferrous casting (automotive sector) • Weight reduction • Magnesium & titanium • Automotive & Aerospace markets • Aluminum – lithium alloys • Meeting requirements in aircraft industry (reducing structural weight).

  4. Plasma assisted Chemical vapor deposition (80000 casts against hard chrome :10000 casts). Surface Coating

  5. Ceramic composite die • A unique nitride / nitride – carbide matrix • Half the weight of conventional steel dies & 10 times the useful life. • Proven stability to molten metals, resistant to corrosion, erosion, oxidation, thermal fatigue and cracking. • Materials & Electrochemical research corporation MERC

  6. Titanium matrix composite tooling • CermeTiTM • Implemented in the form of shot sleeve or a partial liner inserted into an existing H13 shot sleeve. (minimum 4 times cast life).
