The old name is left behind in 1934 in favour of "La Fonte Ardennaise”, which sounds more like a brand. In 1936, Émile Grosdidier, the majority shareholder, becomes the sole administrator. The customer base changes in 1937 as clients from the electricity sector begin to arrive.

Our story


Starting at the beginning of the 30s, mass electrification accelerates with the growth of industrial facilities and housing reconstruction. The company participates in the founding of an electrical equipment manufacturer called ELECTROFONTE. The factory is expanded and more casting operators are employed. The foundry pours between 10 and 15 tonnes of metal each month and has around 15 workers.

Our story

Production increases to around 50 tonnes per month with fifty employees by 1951. Martial Grosdidier, an arts and crafts engineer, joins the company four years later and commences the process of mechanisation. In 1958 the company structure is changed from a limited liability company to a corporation, 70 employees now produce over 100 tonnes per month.

This latest-generation facility was constructed in Guillena in 2005, it is just 30 minutes from the international airport of Seville and brings additional production capacity of 25,000 tonnes to the group. Its two vertical joint moulding lines and the two medium-frequency melting furnaces enable lamellar and spheroidal graphite casting to be done to the most demanding standards. Its location in the south of Spain offers new perspectives for growth in both Southern Europe and North Africa.
