Retracing chronologically the history group, the first step is the “Dosi mechanical constructions”start up which has been integrated in a first moment with the acquisition of Baruffaldy company in Ferrara for what concerne extrusion machines, tools and extrusion lines for plastic profiles and later with the brand “Primac” for pipes manufacturing. Recently DOSI’s head quarter expanded due to the moving of the Baruffaldi’s factory from Ferrara to Fusignano. In this way the expansion and business integration has been completed. The entire team of Dosi’s group work in synergy in order to offer a high quality and competitive level of the finished product. Since it was established in 1953 Baruffaldi Srl has created a solid reputation at an international level as a manufacturer of extrusion tools and extrusion lines for plastics, automatic in-line and off-line machines for PVC profiles, PVC, aluminium and steel roller shutters, cable and installation ducts for the electrical industry as well as for special machines made to spec and turnkey projects. Today with the Primac brand name, it also builds machines for processing smooth and corrugated pipes in PP, PE and PVC.
