Scrap Reduced to Less than 0.03%

Lids Challenge: A major resistor manufacturer wanted to change their design from a ceramic substrate to a less brittle material that was harder to damage in the harsh environment found under the hood of an automobile. It was critical to maintain the same flatness tolerance and ability to preserve co-planarity on the substrate. The million-dollar question was: could metal be held to the same or better flatness specifications?

Solution: Absolutely. Careful process design and monitoring the progressive die produced a 4 x 4 inch stamped metal plate with a flatness variance of less than 0.008 inches.

This is not an expensive run -- inspect -- scrap -- then run some more, operation either. The process boasts consistent control and scrap rates less than 0.03% with hundreds of thousands of plates produced annually.

Isn't quality most cost effective when it is designed into the tools and die at the start of a project? What improvements could precision metal stampings make in your world? Call our design hotline -- 1.888.89.STAMP -- to start exploring the possibilities.
