Servicing the Fabrication Industry for over 95 Years

S. B. Whistler & Sons, Inc. was founded in 1917 as a custom die shop and manufacturer of special jigs and fixtures. Back in 1933, Whistler developed, introduced and patented the world’s first reusable die system for punching and notching sheet metal – a technology that focused international attention on the company and revolutionized the metal stamping industry.

That original, nearly 70-year old technology – now known as the Adjustable Die system – continues to enjoy wide use by leading manufacturers throughout the country. Today, our Magna Die ® and XimmiX ® products represent the second and third generations of modular hard dies, providing worldwide metal fabricators the unparalleled advantages of flexible productivity – with punching solutions that are simple, reusable and affordable.

Whistler design engineers can assist you with economical tooling solutions, from punching the simplest hole patterns, to handling completely integrated, turnkey systems for producing a wide range of sheet metal products – from light fixtures and electrical boxes to trucks and maritime shipping containers … we’ve been there, we’ve done them all and we have the solutions you need.

In addition to design, manufacture and sale of modular die systems, S. B. Whistler & Sons, Inc. is also your source for Metaligner ® – the reusable, expanding dowel system that can be applied wherever conventional dowel pins are specified, and the exclusive US importer of Miva ® modular work holding systems, representing the ultimate in vacuum work holding technology.
