Expert Tooling Solutions for End-Users, Builders and Distributors of Rotary-Draw Tube-Bending Machines

For two decades Bend Tooling Inc. has manufactured innovative products for rotary-draw tube-bending including inserted mandrels and wipers, single-piece poppet links for high-production tube-bending, the offset-geometry wiper feathered edge for high-pressure tube-bending, and tapered-leaf die sets for easy loading and unloading of square and rectangular tubes.

Bend Tooling has now drawn upon this experience to provide an engineer-to-order tooling service for builders and distributors of rotary-draw tube-bending machines.  This is a complete design-and-build tooling service starting from raw data or samples.  It includes expert recommendations on how to process a tube bend ranging from the use of standard sets for single-bend jobs to stacked sets with compound clamps for multi-bend applications to elliptical tooling for hydroforming pre-bend operations.

Bend Tooling also provides tool set-up parameters, troubleshooting advice, and technical bulletins to facilitate process control in tube-bending operations.

Bend Tooling die sets are available in a number of styles:  Inserted, double-inserted, quick-change, integrated stack, platform, and tapered-leaf.  Mandrel and wiper tooling are also available in different styles, inserted and solid-body.  Bend Tooling uses Datafacturing™, an automated manufacturing technology, to quickly deliver top-quality tool sets to machine-builders and distributors. 

All Bend Tooling products are precision-machined to completion — no hand-working —including wiper feathered edges.  All die sets feature a proprietary metallurgy and heat treatment for precision, toughness, and durability.  All mandrels and wipers are manufactured from high-quality nickel-aluminum-bronze, aluminum-bronze, and alloy steels.
