Shot Blasting Machine for Shot Peening and Strengthening

1. When Shot Strengthening is Required

• Fatigue Life Enhancement: Eliminate internal tensile stress, extend service life of parts under cyclic load.

• Stress Corrosion Resistance: Prevent crack initiation and propagation in harsh corrosive environments.

• Wear Resistance Improvement: Refine surface microstructure, increase surface hardness and abrasion performance.

• Post-Weld & Post-Machining Stress Relief: Remove residual stress generated by welding, cutting and machining.

• Surface Defect Remediation: Eliminate tiny surface pits, burrs and micro-cracks.

2. Industries We Serve for Shot Strengthening

• Applicable Industries

• Automotive Manufacturing

• Aerospace & Aviation

• General Machinery

• Petrochemical & Pipeline

• Mold Industry

• Hardware & Fasteners

• Rail Transit

• Engineering Machinery

3. Common Workpieces & Matching Shot Blasting Machines

1. Gears & Gear Shafts

• Workpiece features: Precision transmission parts, bear heavy cyclic load, require uniform stress layer on tooth surfaces

• Matching equipment: Rotary Table Shot Blasting Machine

• Workpieces are fixed on rotary table for multi-angle uniform peening.         

• Ensures consistent strengthening effect on gear teeth.

2. Various Springs

• Workpiece features: Small elastic parts, large production volume, prone to fatigue fracture 

• Matching equipment: Belt Type Shot Blasting Machine

• Parts roll softly inside the rubber belt, realizing all-round peening without deformation. Ideal for mass production of coil springs and leaf springs.

3. Large Shafts & Heavy Structural Parts

• Workpiece features: Long or bulky components, complex shape, high single-piece weight 

• Matching equipment: Hanger Type Shot Blasting Machine

• Workpieces are suspended and rotated during processing to cover all surfaces, suitable for crankshafts, connecting rods and heavy load frames.

4. Small High-Strength Fasteners

• Workpiece features: Tiny parts, huge batch quantity, strict fatigue performance requirements 

• Matching equipment: Barrel Blast Shot Blasting Machine  

• Continuous low-speed rolling achieves efficient mass peening for bolts, nuts and small rivets.

5. Mold Industry: Precision molds, die-casting molds and stamping molds

• Workpiece features: Complex cavities, high precision, requiring stress relief, descaling and deburring.

• Matching equipment: Rotary Table Shot Blasting Machine: For medium & large molds, delivers uniform surface treatment.

• Hanger Type Shot Blasting Machine: For heavy large molds, full coverage for inner cavities and corners.
