The need for flexibility, responsiveness and cost reduction has become of primary importance for all or most of the mass production processes, particularly in Europe. The principles of Lean Manufacturing provide the solution to this need and its application has revolutionised manufacturing methods in recent years, starting from the automotive sector. Starting from this general need of its customers, Samac has looked for and developed solutions that increasingly integrate the features of lean production into the assembly systems, implementing more than 100 dedicated lines and machines in a few years and becoming recognised by the market as a specialist.
