In 1977, after 18 years of experience in Same Group Italia, Mr. Mariolino Manzoni decided to set up on his own and take advantage of the market potential, thereby establishing Meccanica Conti.
Mr. Mariolino invested all his personal resources into developing his company with total dedication and passion and in 1980 STL di Manzoni e C was established.
