Foundry and production process

The foundry is the beating heart and original nucleus of our company: here, in 1910, the story of Fonderie Ariotti began.
We are specialised in large size castings, in ferritic nodular cast iron, pearlitic cast iron, grey cast iron and ductile iron for ADI, weighing up to 80 tons. Our plant covers a surface area of over 15,000 square metres and is equipped with cutting edge systems.
We scrupulously comply with all environmental and safety regulations, to ensure the present and the future of the company with a view to sustainability.

Production Process

Our production process integrates all the technologies necessary for production: from the design and construction of the pattern, to the casting, to the heat treatment and deburring of the pieces.

Pattern stock

A 4.0 safe, compactable and automated

Our new and ultra modern pattern stock is automated and compactable on mobile bases, digitally integrated 4.0 and equipped with the most modern technologies:
