At OMNI Engineering, Inc. we specialize in high volume, precision stampings. The project highlighted here exemplifies our ability to produce retainer clips and high amperage connectors designed for use in military and commercial aircraft.

Composed of UNS C17200 beryllium copper, the finished products had to meet various ASTM, military, and commercial industry standards. The miniature and micro miniature stamping was performed with carbide progressive dies on 30 ton Bruderer presses. Manufactured in various sized, all meet tolerances of +/-0.0005”, and angular tolerances of +/- ½°, which was verified through dimensional, gage, and visual inspections, and through the use of our F.O.V. Smartscope (automated inspection system).

After stamping, the components are heat treated in an nitrogen atmosphere oven and then plated with nickel, gold, or sliver plating (if specified). We currently manufacture 100,000 to 15 million of these electrical components annually to customers in the United States and Mexico.
