Shot Sleeves for Aluminium Die-Casting

The Borga Meccanica SRL produces state of the art shot sleeves for aluminium die casting. We use high quality hot work die steels. After a rough machining the containers are hardened and three times tempered. Afterwards, the inner hole are grinded and polished. Eventually a nitriding treatment increases the surface hardness up to 1000HV. We produce both traditional and thermoregulated containers. The Thermoregulation allows to uniform the temperature of the container at around 200°C reducing failures due to deformations and thermal fatigue.
