One of the main processes deals with by the AZ is the casting.

The casting is the transformation of wax models in gold products ranging from 9 to 22 kt and silver.

The processing cycle has a duration of 24 hours.
The wax models, provided by clients, sorted according to type of product, are mounted on posts in wax and sent to the next stage of creation of the plaster cast.

The plaster mold is emptied of the wax in a special oven (lost wax method), then the part, emptied from the wax, is injected with molten metal, by means of special equipment (induction furnaces with control of temperature and pressure). In this way we obtain, after breaking the gypsum, the reproduction metal of the wax pattern.
