Contract Manufacturing

The term ‘contract manufacturing’ is often widely used, and its definition often widely varying across the manufacturing industry. Bent River views contract manufacturing as a contract to build a nearly complete design that another company brings to us.



We specialize in print-to-part prototyping, or what we like to call, new to the world. Meaning that it will be the first time a part our clients designed will be manufactured. We excel at low volume, mid to high complexity manufacturing projects, turning a concept into reality.


Tooling & Ground Support Equipment

Bent River Machine can engineer, design, fabricate, build, and install a range of custom tooling, from large and complex projects that require several months of work, to simple, quick projects that can be completed within a few days.
