The story of Tranceria Milesi began in 1972 in Brembilla (now Val Brembilla), when Francesco Sonzogni opened his first mechanical workshop in the garage beneath his home, founding a small artisan business focused on blanking. Within a few years, thanks to the reliability of its services, the small workshop began to grow: new machinery and a team of young workers made it possible to expand the offering, adding mechanical assembly and initial surface finishing.

In 1997, the business was handed over to the next generation: Francesco’s nephews – Stefano, Mariagrazia, and Ivan Milesi – took over the company after years of working alongside their uncle. They launched an important modernization of the facilities, enhancing production capabilities while preserving the artisan spirit. New processes such as tumbling and mass polishing were introduced, and a strong focus on quality allowed the company to expand beyond the local market, acquiring customers across the Bergamo province and even in Switzerland.

Between 2005 and 2017, the family business welcomed the next generation: Valentina, Marco, and later Paolo joined the company, bringing fresh skills and a modern organizational approach. This generational shift supported the adoption of advanced technologies and process optimization, without ever compromising the craftsmanship that has always set F.lli Milesi apart.

Today, with over fifty years of experience, the company offers an integrated service — from raw sheet metal to the finished component:

Sheet metal blanking and forming, for both small and large production batches

Tumbling and polishing, to ensure uniform and glossy surfaces

Assembly and packaging, with tailored solutions

We continuously invest in safety, efficiency, and clean technologies, in order to deliver high-quality products and custom services — always staying true to the artisan spirit that defines who we are.
