This metal pad is used in an aerospace application where safety is the critical factor. Tolerances are tight —a slight convex distortion would result in rejection. Initial production was a disaster. Our QC department rejected a substantial percentage of the run. Delivery time soon became critical.
We quickly determined the root cause of the problem was uneven heat treating. It was warping the part. Working closely with our supplier, a special fixture was designed to hold the part differently. Within days the rejection rate had dropped to zero.
