Context and positioning

High-performance automotive (premium OEMs, motorsport, top-tier suppliers) applies shot peening extensively on critical mechanical components — gears, springs, crankshafts, conrods. These applications are qualified to IATF 16949, SAE J442/J443.

Typical operations

Shot peening on gearbox and transmission gears

Tooth root — bending-fatigue improvement per ISO 6336.

Shot peening on suspension and valve springs

Coil and leaf springs, engine valve springs.

Shot peening on crankshafts and conrods

Fillet radii, fatigue-initiation zones.

Peening on motorsport prototypes

Short-series F1, rally, endurance — qualified processes.

OEM standards and specifications

▸ SAE J442, SAE J443 — Automotive peening
▸ IATF 16949 — Automotive quality management
▸ ISO 6336 — Gear fatigue
