Shot Peening: Professional Excellence Across Industries
Shot peening is a precision surface treatment that transforms component performance through controlled mechanical deformation. Far more than a routine process, it requires deep material science knowledge, advanced equipment calibration, and strict quality control—qualities that define our expertise at ShanFeng. Below, we detail our professional capabilities, key industry applications, and the tangible advantages of our shot peening services.
The Professionalism Behind Our Shot Peening
Our process is built on three pillars of technical rigor:
1. Engineering Precision
Every project begins with material analysis. We evaluate factors like:
- Material hardness (e.g., 30–45 HRC for aerospace alloys)
- Surface geometry (curvature, thickness, and critical edges)
- Operational stress loads (tensile vs. compressive environments)
This data informs media selection (steel shot, ceramic beads, or glass grit), intensity settings (measured via Almen strips: 0.005–0.030” arc height), and coverage (100–300% for uniform stress distribution).
2. Compliance & Certification
We adhere to global standards, including:
- AMS 2430 (aerospace component requirements)
- ISO 11432 (safety and equipment specifications)
- General Motors GMW14872 (automotive industry benchmarks)
Our quality management system tracks every batch with detailed reports, including residual stress measurements (via X-ray diffraction) and surface roughness data (Ra 1.6–6.3 μm, depending on application).
3. Advanced Equipment & Expertise
Our facility features:
- Automated robotic systems for complex parts (±0.002” positional accuracy)
- Manual stations for intricate geometries (e.g., turbine blade roots)
- Real-time monitoring software to adjust pressure (40–120 psi) and media flow rates (5–20 kg/min)
Our technicians hold certifications in shot peening process engineering, with an average of 8+ years of industry experience.
Key Industries & Products We Serve
Shot peening enhances performance across sectors where durability and reliability are non-negotiable:
1. Aerospace & Defense
- Products: Turbine blades, landing gear struts, rocket engine nozzles, and missile components.
- Goal: Extend fatigue life in high-temperature, high-stress environments. For example, peening turbine blades reduces crack propagation by 50% under cyclic thermal loads.
2. Automotive & Racing
- Products: Transmission gears, valve springs, suspension components, and racing engine parts.
- Goal: Improve wear resistance and handle extreme torque. Our process increases spring fatigue life by 30–40% in performance vehicles.
3. Energy & Power Generation
- Products: Wind turbine shafts, power plant turbine rotors, and hydraulic fracturing equipment.
- Goal: Resist corrosion and fatigue in harsh conditions (e.g., offshore wind farms).
4. Medical Devices
- Products: Orthopedic implants (e.g., hip stems) and surgical tools.
- Goal: Enhance biocompatibility and surface finish without compromising strength.
