How an aluminium die casting is made at Sunmax

One automated cold-chamber cycle — from the Silcarb holding furnace to an inspected casting on its way to your assembly line.

Animated high-pressure aluminium die casting cycleMolten aluminium is ladled from the holding furnace into the shot sleeve, injected by the plunger into the clamped steel die, cooled, ejected as a finished casting and carried by conveyor through inspection.685°CSHOTCLAMPDIECMM · X-RAY
  1. Stage 01

    Melt & Hold

    Certified ingots melted and held in Silcarb furnaces at 685°C ± 5°C.

  2. Stage 02

    Ladle Transfer

    Degassed alloy metered by ladle into the cold-chamber shot sleeve.

  3. Stage 03

    High-Pressure Injection

    The plunger drives molten aluminium into the clamped steel die.

  4. Stage 04

    Solidify & Cool

    Die cooling channels set a fine, repeatable microstructure.

  5. Stage 05

    Die Open & Eject

    Robotic extraction lifts the near-net-shape casting out of the die.

  6. Stage 06

    Trim & Inspect

    Runner cutting, then CMM and X-ray checks before DOL dispatch.
