This website has been developed in order to offer a brief introduction to the world of development and manufacture of moulds for aluminium die casting.
The transformation of metals into finished parts through the die casting procedure is a very old practise which was already known by the Egyptians.
The most used materials are:
- Aluminium and its alloys;
- Copper and its alloys (bronze, brass);
- Magnesium and its alloys;
- Zamak;
-
Tin and its alloys.
The word “die casting” indicates the casting procedure in which the filling of the mould occurs through the pressure which a press executes on the melted metal.
The form of the piece is gained through the mould therefore the manufacture of moulds for aluminium die casting has to be carefully executed.
For a correct manufacture of moulds for aluminium die casting it is essential to choose the right type of steel and the most suitable heat-treating. There are basic elements that give the mould the technical-mechanical features of a heat pump.

Casting is a manufacturing process by which a molten material such as metal or plastic is introduced into a mold, allowed to solidify within the mold, and then ejected or broken out to make a fabricated part. Casting is used for making parts of complex shape that would be difficult or uneconomical to make by other methods (such as cutting from solid material).Casting may be used to form hot, liquid metals or meltable plastics (called thermoplastics), or various materials that cold set after mixing of components such as certain plastic resins (e.g. epoxy), water setting materials such as concrete or plaster, and materials that become liquid or paste when moist such as clay, which when dry enough to be rigid is removed from the mold, further dried, and fired in a kiln.
Substitution is always a factor in deciding whether other techniques should be used instead of casting. Alternatives include parts that can be stamped out on a punch press or deep-drawn, forged, items that can be manufactured by extrusion or by cold-bending, and parts that can be made from highly active metals.
