In 1948, Mr Louis Bélet, former country watchmaker, created in Vendincourt, the only end mills fabrication workshop of what would later become the Canton of Jura.

In 1981, his children, Madeleine, Louis, Marc and Guy took over the Company, which had then less than 10 employees and organised it as a Public Limited Company. Over the following years, Louis BELET business grew considerably.

In 1986,BELET designed and developed its 1st computer numerically controlled (CNC) machine on its site.

In 1990
, the substantial increase of staff number and equipment necessitated the increase of production surface, from 90 sqm to 300 sqm.


In 2000, the operation surface reached 1,100 sqm through a 2nd expansion.

In 2002, Louis BELET was awarded the ISO 9001 et 14001 certification, demonstrating the compliance of its quality management system and its respect of environmental conditions.

In 2008, the company management is taken over by the two grandchildren of the founder, Mrs Roxane Piquerez and Mr Arnaud Maître.


In 2010, Louis Bélet has finished in 2010 its third major extension. The production area has reached 1700 m2, in addition to the new administrative and technical rooms.

This new building incorporates the principles of sustainable development. It delivers good working conditions, with a controlled temperature of the air and of the cooling fluid. This ensures a good comfort for the employees and a reliable production process all year long.

The administrative building, labelled "Minergie", is heated by collecting the heat produced within the workshop.


In 2018, Louis Bélet (LBSA) is once again cramped in its Vendlincourt premises. Faced with the urgent need to install new grinding machines to meet new markets, the premises of a Relay Factory are rented in Porrentruy, 10 km away from the headquarters.


One year later, LBSA acquires a neighbouring plot of land in this industrial zone in Porrentruy and buys the building that had been rented until then. Modification and expansion work on these premises is planned for the end of 2020, in order to accommodate new projects.
