3 Major Manufacturing Facilities

3 Main Shot Peening Service Options

Shot Peening Sharing Center

  • Location: Flexible selection of nationwide centers nearby (deploying suitable shot peening equipment across China based on customer requirements for processing support).
  • Target Products: Ideal for small-batch subcontract processing, typically suited for clients in the process development and validation stage or small-scale batch production stage.

Shot Peening Service Station

  • Peening Location: Establish a shot peening service station directly at the customer's job site.
  • Peening Products: Suitable for high-volume incoming material processing; the service station is managed by the local MAP company.
  • Customer Value: Helping customers reduce equipment investment and logistics costs, optimize production schedules, and ensure superior product quality to boost their market competitiveness through professional shot peening quality management (man, machine, material, method, environment, and measurement).

Mobile Shot Peening Machine

  • Convenience: Containerized, all-in-one integrated design for easy transportation.
  • Cost Reduction: Transportable with no foundation pit required—simply place it directly on the ground to lower equipment investment costs. Featuring nine integrated systems and its own power source, it truly achieves plug-and-play capability.
  • Comfort: Equipped with LED lighting, emergency lighting, non-slip steel flooring, a comfortable air-conditioned cabin, and a rest area. The air intake provides ventilation for the main unit, delivering a true all-in-one, fully closed-loop system.

Technical Principles & Advantages

Principle of Shot Peening:

The shot peening process involves bombarding the workpiece surface with high-hardness, high-velocity media to induce localized plastic deformation. This deformation generates a microstructurally strain-hardened layer and a layer of compressive residual stress on the surface. Consequently, it enhances the part’s fatigue strength, stress corrosion resistance, resistance to crack propagation, and wear/fretting resistance, significantly extending component service life.
Turned Surface
Shot Peened Surface

-01

Enhanced Fatigue & Stress Corrosion Resistance:
Substantially improves the fatigue strength and stress corrosion resistance of mechanical parts and structural components.

-02

Simplified Process:
Requires only a single processing step, making it straightforward and efficient compared to other surface treatment methods.

-03

Surface Texture Modification:
Alters surface roughness, imparting a uniform matte finish.

-04

Subsurface Reinforcement:
Introduces a profound compressive residual stress layer in the surface and subsurface regions, effectively strengthening the entire component surface.

-05

Microstructural Refinement:
Induces surface plastic deformation, transforming retained austenite into martensite, refining the grain structure, and forming a strain-hardened layer.

-06

Corrosion Inhibition
Converts surface residual tensile stresses into beneficial compressive stresses, effectively suppressing crack propagation and significantly boosting stress corrosion resistance.

Cooperation Process

01
step
Requirement Communication & Process Assessment
The customer provides part drawings, material, dimensions, shot peening intensity, surface roughness, and capacity requirements. Our engineers conduct a one-on-one analysis to match the corresponding shot peening process, equipment, and processing plan.
02
step
Sample Processing & Inspection Confirmation
A small batch of test samples is received and processed. A professional inspection report (covering roughness, residual stress, and coverage rate) is issued for the customer to confirm process standards.
03
step
Quotation & Contracting
A formal quotation is issued based on volume, processing duration, and logistics costs. A processing service contract is signed, detailing delivery deadlines, quality standards, acceptance criteria, and after-sales guarantees.
04
step
Material Receiving & In-Plant Processing
The customer sends the parts to be processed to the nearest shared shot peening service center nationwide. Standardized production is conducted throughout the entire workflow, implementing complete quality management across Men, Machine, Material, Method, Environment, and Measurement (5M1E), with real-time updates on processing progress.
05
step
Finished Product Inspection & Acceptance Dispatch
Full inspection is conducted on completed parts, checking residual stress, surface appearance, and dimensional tolerances. Qualified products are packaged and protected, then delivered together with the inspection report.
06
step
Logistics Delivery & Long-Term After-Sales
Finished products are delivered to the customer’s facility. We provide one-stop value-added services, including long-term process optimization, spare parts support, and on-site station setup.
