Baileigh Launches Mini Mandrel for Precision Tube Bending

Manufacturers working with small-diameter tubing now have an innovative solution to achieve precision bends without investing in new equipment. Baileigh Industrial has unveiled its revolutionary Mini Mandrel Attachment, designed to transform the RDB-350 tube bender into a compact yet high-performance mandrel bending solution for tubing up to 1.5 inches in diameter.

Precision Engineering for Small-Diameter Applications

The manufacturing sector, particularly industries like aerospace, automotive components, and medical devices that demand exacting tube bending precision, often faces challenges with small-diameter workpieces. Traditional rotary draw bending methods can result in uneven wall thickness, internal wrinkling, and excessive outer wall stretching when processing smaller tubes.

Mandrel bending technology addresses these issues by providing internal support during the bending process, ensuring wall integrity and precise form retention. However, dedicated mandrel benders represent a significant capital investment that may be prohibitive for small-to-medium enterprises or operations with specialized low-volume production needs.

Seamless Integration and Rapid Deployment

The Mini Mandrel Attachment features a design philosophy emphasizing both usability and efficiency. Installation requires minimal downtime, with no need for specialized tools or technical expertise. The complete assembly process, using ten included bolts (six for the main worktable and four for the sliding pressure die assembly), typically completes within 30 minutes.

This rapid deployment capability allows manufacturers to quickly expand their RDB-350's functionality into mandrel bending applications while maintaining production continuity. The purely mechanical design eliminates dependence on hydraulic or electrical systems, ensuring reliable operation across various working environments.

Expanding Manufacturing Capabilities

This innovation significantly broadens the RDB-350's application range, particularly for prototyping and low-volume production scenarios. The attachment enables precision bending for demanding applications such as automotive exhaust systems, medical tubing, and aerospace components where dimensional accuracy is paramount.

The solution effectively bridges the gap between general-purpose rotary draw bending and specialized mandrel bending equipment, allowing manufacturers to maintain versatility while meeting stringent quality requirements for small-diameter tubing applications.
