The continuous industrial development during the post-war period of the 50's and 60's offered O.A.S.A. the opportunity to participate in new markets and to start working with the automotive industry. The production of components for oil and air filters as well as for filters for industrial applications helped O.A.S.A. to quickly attract prestigious customers from Italy and abroad.

Later, after having acquired significant experience in the manufacture of car components, O.A.S.A. further increased its product range. The company favoured technological innovation in order to offer its customers a complete line of stamping, assembling and high specialized automated welding systems. Our image could thus be enhanced on the Italian as well as on foreign markets; in fact, 30% of our production is actually bound for export.

O.A.S.A. never ignored technical development. It adapted to the structural changes of industry not only by gradually upgrading all old machines and facilities during the past few years, but also by solving all problems regarding automation, internal organization, and quality. In 1993, O.A.S.A. was one of the first Italian enterprises to be certified ISO 9002.
