Machine shops with in-house shot peening in California

Shot peening bombards a surface with media to induce compressive stress and improve fatigue life — a controlled process on aerospace and automotive parts, done in the shop.

Give the spec (AMS 2430 or SAE J2441), intensity and coverage, and the areas to mask; ask how they verify intensity (Almen strips) and whether NADCAP covers it.

The shops — 2

Each shop's verified shot peening fact is quoted from its own website; open the shop for every other capability on record.
