Continuous improvement is a mandatory attitude in production systems, especially for Valeo which has a specific branch of the “5 Axes” methodology dedicated to it. During my internship activities in Santena plant, I had the opportunity to analyze and improve many criticalities found on a semi-automatic production line, in terms of safety, efficiency and ergonomics. Specific problems have been identified since we are dealing with a multi-purpose line which was initially designed to produce small electrical components for comfort and driving assistance features, belonging at the homonymous Business Group. At a later time, quite bulky and complex products were introduced on the line, such as the “Carrier” central tunnel for Ferrari vehicles, which includes several driving commands on the same structure.
