Every last drop of molten metal is poured. For this purpose, small moulds placed next to the large ones are there to be filled with the rest of the casting. It takes years of apprenticeship for these artist-workers to acquire the precise gesture. Furthermore, in a foundry, safety instructions need to be followed strictly to prevent accidents as much as possible. Each object that is shaped requires great dexterity and good foundry workers and moulders are highly sought after in the metal industry. The entire production chain depends on the quality of the casting, which determines the quality of the parts produced.
