BELIEVING IN TECHNOLOGY. OVER 30 YEARS OF COMMITMENT AND SATISFACTION. Engineering and production of Weighing and dosing systems. Special plants for Industry, Agriculture and Zootechnics. In 1979 Renato Trombini starts his first business venture in Isorella, firstly focused on design and production of load cells. In 1988 the first automatic milk machine for calves is built; a couple of years later the project for the production of the first model of electronic weighing indicator starts. In 1992 the company moves to Visano, in the current building, which was firstly expanded in 1996, by enlarging the engineering and electronic production area, and then also in 2006, with the further development of the area dedicated to load cell production, warehouse and offices. In 2003 the company starts its growth abroad, thanks to the first official importers; in 2010, along with the turnover growth, there's a strong development of the official PTM dealers in the main European markets. On the occasion of the 30th company anniversary, the business was passed between generations: Renato leaves the company leadership to his son, Mauro.
