smelting of lead, tin and ordinary bronzes.
The smelting weight ranges from 100g to 30 kg.
Among the many applications we would like
to highlight are:
impellers and diffusers for submersible pumps,
cranks for high pressure and agricultural pumps,
circulators,
valves and castings for the mechanical
industry in general.
