Gravity Die Casting

The traditional casting process is of manual nature & cost-effective way to produce small volumes of smaller aluminium parts.

A traditional manual process mastered by few

In gravity die casting, molten aluminium at 750°C is poured into a metallic mould.

This method is suited for small-volume production or when improving mechanical properties through heat treatment is required. The tooling costs are somewhat higher than in casting methods using expendable moulds (sand casting).

The method allows for very close tolerances and fine surface finish. With the use of sand cores, gravity die-casting can be used to manufacture very complex components.

Typical products produced by gravity die casting are diesel engines’ air intake components and flow system valves, as the curved inner shapes can be optimized for gas or liquid flow.

Produce small quantities cost-effectively

Gravity die casting is a form of permanent mould casting. This traditional casting process is of manual nature: the quality of the part is highly dependent on the skill of the operator.

It’s a cost-effective way to produce small volumes of smaller aluminium parts. Alteams Loppi factory has over 20 years of experience in applying this method to various industrial applications.

A traditional manual process mastered by few

The art of gravity die casting is mastered by our experienced operators in Loppi and Laihia, Finland.

The operator takes molten aluminium from the melting furnace with an aluminium dipper and manually pours it into a mould. By controlling the pouring speed, operator ensures the part is formed in the desired structure.
