Product Description

Regular hexagonal bionic vibration damping pad｜20-22mm thickness｜8-12dB high-efficiency noise reduction｜30% structural material reduction｜Ultra-high cost performance

PRODUCT FUNCTION

Bionic structure efficiency enhancement:

- The regular hexagonal honeycomb structure precisely disperses shock waves, increasing vibration energy conversion efficiency by 40%

- Achieves 8-12dB noise reduction at a thickness of 20-22mm, breaking through the performance limit of thin vibration-damping materials 

Lightweight and cost reduction: 

- The mesh structure reduces material usage by 30% while maintaining equivalent load strength (≥12MPa)

- Reduces unit area cost by 35%, significantly optimizing engineering budgets

Broadband vibration damping: 

- Non-linear stiffness characteristics cover the main vibration frequency band of 50-500Hz, suppressing equipment resonance peaks 

Convenient engineering adaptation: 

- Molded sheets support on-site cutting, flexibly matching special-shaped equipment bases
