Structural Adhesive
First development and mass production application of Structural Adhesive technology for VOLVO construction equipment
Mass production of an automated Structural Adhesive system
Key advantages of mass production application of Structural Adhesive
he first case of applying Structural Adhesive to VOLVO excavators.
Improved joint strength
- Maintains high strength by reducing concentrated stress from spot welding through surface bonding with Structural Adhesive
Corrosion prevention
- Applied to the vehicle body before the painting oven process
Weight reduction
- Enhanced strength through the use of Structural Adhesive
- Enables the use of thinner steel materials
-
Mach Original Performance Metrics:
- Static & Dynamic Stiffness
- Side Impact
- Roof Strength
- Front Offset Deformable Barrier
-
Conclusion
- Steel-optimized design: 224.9 kg
- After applying Structural Adhesive, the final body weight was reduced by 14.9 kg
Improved vibration and noise performance
-
Approximately 60 meters of Structural Adhesive applied
- Reduced structural contact noise in the BIW (Body-in-White)
-
Reduced vibration at bonded joints
- 3dB over 80Hz~150Hz
- 5dB over 330Hz~400Hz
- 3dB over 650Hz~720Hz
