High Pressure Die Casting

Molten aluminum alloy is fed, via a shot sleeve, using a plunger, into a temperature controlled metal mold, cooled by water circuits and operated by a hydraulic press.

The solidification of the part takes place by means of overpressure applied by the plunger itself, to compensate for shrinkage.

Due to high speed and high pressure, sand cores cannot be used.  Each internal hollow cavity of the castings has to be designed and set by metallic pins in the mold.

Technology suitable for high volume production of dimensionally precise high quality castings.
Thin and homogeneous metal microstructures are achieved thanks to the fast solidification of the parts.
