Product Overview

Our steel drum expansion machine is a dedicated and essential forming equipment specially engineered for metal barrel manufacturing lines, mainly applied for diameter expansion, rounding and shaping of welded steel drum bodies. It perfectly matches the post-weld forming procedure for industrial steel drums, chemical packaging barrels and daily storage barrels, helping manufacturers obtain standardized drum blanks with excellent structural performance.

Adopting mature hydraulic drive system and integrated automatic control module, this expander realizes full-process automatic operation including automatic feeding, precise positioning, uniform expansion and finished product unloading. The hydraulic system provides stable and adjustable expansion force to ensure even stress distribution on the drum body. It effectively solves common problems such as irregular 

roundness and uneven caliber caused by welding deformation, delivering drums with consistent wall thickness and smooth surface.

Designed for diversified production demands, the machine supports flexible adjustment to process steel drums with specifications from 10L to 

200L, covering open-top and closed-type metal barrels. Featuring high working efficiency of 5-10 pieces per minute, it is compatible with standalone use and collaborative operation with other flanging, seaming machines to form a complete steel drum production line.

Built with high-strength thickened steel frame and wear-resistant alloy mold parts, this equipment boasts sturdy structure, strong shock resistance and long service life. Additionally, it features energy-saving decompression design, simple operation and low maintenance cost. We provide one-stop technical support and after-sales service, making this cost-effective expansion machine your ideal choice to upgrade drum production and improve product competitiveness.

Technical Specifications

Product Advantages

1. Hydraulic + PLC Control, Simple Operation: Hydraulic drive for expansion block extension and retraction, resulting in low impact and stable operation; Siemens PLC touchscreen allows for setting rib positions, quantity, and depth with one-button switching.

2. Compatible with Multiple Specifications: Applicable to barrel diameters of φ350~600mm, barrel heights of 250~1000mm, and thicknesses of 0.5~1.5mm, handling 18L~250L barrels in one machine; supports single-sided/double-sided rib expansion. 

3. Excellent Forming Quality: Rigid segmented punch static extrusion produces full ring rib contours, adjustable height of 15~25mm, good barrel roundness, and significantly improved strength.

4. Compact and Durable, Easy Maintenance: The entire machine weighs approximately 5 tons, occupying a small area; the expansion blocks are heat-treated for wear resistance, and the guide rails have centralized lubrication, requiring minimal daily maintenance.
