Our steel drum washing and drying line is the essential pretreatment equipment positioned before the painting stage, completing the critical cleaning and surface treatment processes that ensure paint adhesion and corrosion resistance. This automatic line performs pre-degreasing, degreasing, water rinsing, phosphating, and hot air drying in a continuous conveyorized system. It handles drum bodies, bottoms, and lids for both open-top and closed-top steel drums, with electromagnetic speed control for adjustable production rates. The phosphating stage creates a chemical conversion coating on the steel surface that significantly improves paint adhesion and rust prevention—skipping this step often results in peeling paint and premature corrosion. The drying oven features hot air circulation with PID automatic temperature control ranging from room temperature to 120°C, using a fuel-fired heating system for efficient drying of wet drums before they enter the spray booth. Available in low, medium, and high-speed configurations with PLC automation for seamless integration into your full steel drum production line, we provide customized line layouts, installation guidance, and comprehensive after-sales support to ensure your painted drums meet quality standards.
