The “pattern” is essentially a replica of the object about to be cast. Usually made out of wood, metal or model board, patterns are used to create cavities in moulds.
It is through pouring molten metal into these moulds that aluminium castings are created.Patterns are a model for the object to be cast.
A pattern makes an impression on the mold, liquid metal is poured into the mold, and the metal solidifies in the shape of the original pattern.
