The challenge
Coil and valve springs were failing fatigue endurance tests 18–22% below the required cycle count. The existing mixed media produced inconsistent Almen intensity, leaving compressive-stress coverage out of specification.
The solution
Replaced the worn mixed media with uniformly conditioned cut wire shot (CW-0.8) and re-established a stable operating mix with a documented Almen control plan, bringing intensity variance within ±0.001A.
30% reduction in blast cycle time
