Our steel drum liner beading machine is specially designed for forming reinforcing beads on the inner wall of steel drum liners and solar water heater tanks, significantly enhancing the strength of the container body . The machine features a horizontal dual-spindle configuration with hydraulically driven expansion heads that insert into the open ends of the drum liner and expand radially outward, forming precise circumferential corrugations with clean profiles. Key specifications include: effective working length up to 2000mm, processing material thickness from 0.2mm to 1.2mm, and pneumatic/hydraulic system pressure at 0.5MPa . Production efficiency reaches approximately 3 seconds per piece with a compact footprint of 2.5m × 0.8m × 1.7m and power consumption of 0.75kW . Available in semi-automatic and fully automatic configurations with PLC control, our beader features easy operation, adjustable bead depth and position, and integrates seamlessly with production line conveyors for automated loading and unloading. Backed by over 10 years of manufacturing experience, we provide customized beading solutions, installation guidance, and comprehensive after-sales support to ensure your steel drum liners achieve the structural integrity required for safe stacking and shipping.
