Our Shot Peening Services
1. Professional Shot Peening for Aerospace Components
Aerospace applications demand zero tolerance for error. Our aerospace-grade shot peening processes are engineered to meet strict standards like AMS 2430 and SAE J442.
- Turbine blades and engine components
- Landing gear and structural parts
- Fasteners and high-stress alloys
By inducing controlled residual compressive stress, we extend component lifespan by up to 40% in cyclic load environments—critical for aircraft safety and operational efficiency.
2. Specialized Shot Peening for Aluminum
Aluminum's lightweight properties make it indispensable in aerospace, automotive, and defense, but its surface integrity requires specialized handling.
- Use softer media (glass beads, ceramic shots) to avoid surface damage
- Optimize intensity to prevent work-hardening while enhancing fatigue resistance
- Support alloys including 6061, 7075, and 2024
Key Benefits for Aluminum:
- Improved corrosion resistance
- Enhanced adhesion for coatings (e.g., anodizing, painting)
- Reduced risk of stress corrosion cracking
3. Custom Shot Peening Solutions
No two components are identical. We design tailored processes for:
- Non-standard geometries (e.g., complex manifolds, thin-walled parts)
- Unique material blends (e.g., aluminum-lithium alloys)
- Specific industry requirements (e.g., medical device biocompatibility)
Our engineering team collaborates with clients to map parameters—from media type to exposure time—ensuring compliance with your exact specifications.
The Shot Peening Process: How It Works
Our standardized workflow guarantees repeatability:
- Pre-Treatment Inspection
- Dimensional checks and surface cleanliness verification
- Material certification review (e.g., alloy composition)
- Parameter Setup
- Media selection (steel shot, glass beads, ceramic)
- Intensity calibration via Almen strips (N, A, or C type)
- Coverage adjustment (100-300% per customer requirements)
- Process Execution
- Automated or manual peening (depending on part complexity)
- Real-time monitoring of pressure, media flow, and exposure time
- Post-Process Validation
- Residual stress measurement (X-ray diffraction)
- Surface roughness testing (Ra/Rz values)
- Compliance documentation for traceability
