Precision Metal Stamping

NN, Inc.’s Precision Engineered Products Group’s engineers, tool and die makers, and technicians design, build, and maintain highly productive metal stamping tools for electrical products. The group maintains precision metal stamping capability with close tolerances, and custom-cleaning processes are available in-house.

Electrical and electronics products include subminiature to large precision metal stampings for connectors, hybrid packaging, lead frames, heat sinks, and other computer and electronic applications. Precision Engineered Products Group makes parts with tight critical dimensions and cosmetic requirements at quantities to millions per week. It also produces a wide variety of metallic stampings for the electrical, defense, appliance, and electronic industries.

The group’s engineers are experts on materials that support customers’ manufacturing, component performance, and cost objectives. Base metals, particularly copper and copper alloys, are used extensively in switches and electrical components. Thermostat metals are utilized for parts designed to move precisely as heat is added or taken away. Precious metals are primarily used for electrical contacts. Clad metals used in electrical contact applications are often a copper-based material with inlay, overlays or tri-metal layers that provide optimal precious metal placement and utilization.


The group’s dedication to quality is reflected in new technology and applying the benchmarks of the most current quality system requirements: ISO 9001:2008 and ISO 13485:2003. Our goal of eliminating defects is continually improved by utilizing automated vision systems, error proofing, and 100% inspection of critical characteristics and processes.
