Last few years, our continuous investment on I+D+I solidified diverse technical improvements. Nevertheless, what has really globally revolutionary been, is the application on laser technology for hydraulic cylinders welding (patented system). Nowadays, Cicrosa is the unique globally enterprise which applies laser technology for hydraulic cilinders welding. Over the years, Cicrosa participated in investigation projects and industrial development, at European and national level, in order to improve the manufacturing processes.
