We manufactured the small steel spring highlighted here for use in a real-time stenography system that court reporters, closed captioners, voice writers, and others use to convert speech to text. Fabricated from .025” thick annealed spring steel, our experience taught us how to apply the exact forces to blank, pierce, and form this delicate component on our lower tonnage punch presses. Additional operations involved heat treating to RC 40-45 hardness and plating with a zinc flash finish. The parts were then baked to relieve hydrogen embrittlement that could cause premature cracking or fracturing.
When completed, the springs measured 1.285” in length x .275” in width. Quality assurance consisted of both hardness testing and dimensional inspections to confirm we satisfied the requirements of the customer specification. Our ability to manage this project from start to finish reduced production time and provided the client with the cost advantages associated with using a single supplier.
