STM & GSM

Year 1976 is not only a date for S.T.M. It represents the starting of a small company that is today an important reference point in the mechanical transmission field, thanks to the entrepreneurial capabilities (from foundation members Girotti Tiziano, Vignoli Altero and Lucchini Giuseppe), expertise and firm commitment of the promoting partners.
S.T.M. over 90' has turned from a craftsmanlike expression into a big industrial company specialised in the design and manufacturing of speed reducers.
S.T.M. is nowadays well known in national and international markets in which has reached a respectful position.

In 1998 S.T.M. achieved ISO 9001 Certification, with the aim to grant a good quality system for the different market needs.
Today S.T.M., using modern design systems and high-tech production machinery (working centres, gear cutters, and sophisticated grinding centres), can offer a wide range of speed reducers, electric motors, mechanical and electronic variators.
