The hydraulic pre-curling and flanging machine is a specialized forming machine used in steel drum manufacturing for preparing and shaping the edges of drum bodies. Through hydraulic pressure and precision forming dies, the machine performs pre-curling and flanging operations to create uniform and accurately formed drum edges, providing an ideal foundation for subsequent seaming and closing processes. Designed for 200L steel drums, chemical barrels, oil drums, and industrial metal containers, the equipment offers stable hydraulic pressure, consistent forming quality, and reliable operation. Its automated control system helps reduce manual intervention while improving production efficiency and dimensional consistency. The machine can be integrated with seam welding machines, ribbing equipment, seaming machines, and conveying systems to form a complete automated steel drum production line.
