Compression Spring With Such Tight Tolerences It Could Not Be Made Automatically

A computer manufacturer needed a compression spring that had to be so precise that it defied automatic manufacture. The compression spring also had to be made out of an alloy that was very sensitive and changed more than acceptable limits in the heat treating aspect of the application. The manufacturer went to many vendors to see if they could get the compression spring they needed but most turned them down. Hardware Products also discovered that it could not make the spring automatically according to the very tight parameters. We did however discover that we could make a go/no go gauge that would very rapidly distinguish the acceptable springs from the unacceptable springs and in that way were able to give the customer the very tight tolerances that they needed at what was a reasonable cost.
