Chillcasting, also called gravity diecasting, consists of casting aluminium alloys in permanent steel moulds. Patterns for chill casting are produced from steel on state-of-the-art machine tools.
Uniform castings suitable for CNC machining are thus ensured.
Rapid cooling in the steel moulds improves the mechanical properties of the alloys.
Internal shapes and cavities can be produced in chill castings by means of steel mandrels or sand cores.
The method is suitable for large or medium-sized batches.
