Process innovation drives custom, rapid-response manufacturing solutions

Despite the rise in popularity of outsourcing in the manufacturing industry over the past few decades, Superior Die Set Corporation has chosen to keep production right where it’s been for almost a century – in house.

Rather than looking for a quick-fix to cut upfront costs, we focus on maintaining quality and efficiency, streamlining processes and delivering a wide range of standard to custom solutions – faster. We stock our own materials, make our own parts and track the entire process, saving time, maximizing value and minimizing liability. That’s how we compete.

While other manufacturers are waiting for steel or components to arrive, we’re already making product – fulfilling orders with shorter lead times and tighter deadlines. Applying our innovative in-house processes to everything we do enables us to meet the broad manufacturing needs of a variety of customers across a wide range of industries.
