Aluminium die-casting dies
Custom-designed and -built aluminium die-casting dies for high-performance industrial manufacturing, ensuring consistent quality and a long service life.
Bespoke moulds for aluminium die casting

Groppalli manufactures aluminium die-casting dies designed to customer specifications, with the aim of ensuring precision, reliability and continuity of production.
The die casting mould, using liquid aluminium, makes it possible to produce complex three-dimensional components directly, even those featuring ribs, holes, thin walls and intricate geometries.
Precision engineering and ongoing support
The company stands out for its precision in manufacturing, rapid response times and ability to offer customisation. Its experience in producing complex moulds enables it to develop reliable solutions even for high-volume production, with rapid maintenance and ongoing technical support to minimise production downtime.

Steels and alloys used for die-casting moulds
The choice of materials is tailored to the thermal and mechanical stresses typical of aluminium die casting, to ensure the mould’s wear resistance and long service life.
- ORVAR Supreme / DIEVAR — hot-work steels for mould components in contact with molten aluminium
- COBRAL — alloys for inserts with high thermal conductivity
- MARLOK — high-conductivity steel for mould temperature control
- BB2 (copper-beryllium) — inserts for areas requiring rapid heat dissipation
