In the railway sector, industrial washing and surface treatment of mechanical parts and metals is essential to ensure safety and reliability, as well as prolonged resistance. In particular, washing is carried out to remove oils, greases, dust, and other processing residues using spray systems, immersion with or without ultrasound. These processes prepare surfaces for subsequent treatments such as sandblasting, shot blasting, and phosphating. These processes improve coating adhesion and corrosion protection. Other treatments, such as painting, galvanizing, and passivation, are used to increase the durability of parts subjected to extreme environmental conditions. In the railway sector, the efficiency and quality of these processes are essential for compliance with the technical and regulatory standards of the industry.
