Product Description

This series of products is developed forward based on finite element computational mechanics analysis and manufactured using high-precision injection molding technology. The core rubber materials and performance parameters support customized design according to customer needs, featuring both a compressive strength of ＞12MPa and a performance retention rate of ＞95% after 5 million dynamic fatigue cycles. Compliant with EN45545-2 HL3 fire protection standards and TB3139 environmental standards, they provide long-term vibration damping protection for high-end buildings and industrial equipment.

PRODUCT FUNCTION

Scientific structural design:  

Finite element simulation of over 100,000 working condition loads optimizes stress distribution, avoiding the risk of local failure.  

Customized stiffness curves match the vibration spectrum of equipment, increasing resonance suppression efficiency by 30%.  

Cutting-edge process guarantee:  

Fully automatic injection molding achieves ±0.1mm dimensional accuracy, with batch consistency reaching 99%.  

Adhesion strength of rubber-metal inserts ＞8MPa, eliminating the hidden danger of delamination.  

Extreme environment durability:  

Dynamic modulus fluctuation ＜5% within the temperature range of -40℃~80℃, ensuring stability under wide-temperature working conditions.  

Height change ＜3% after 5 million fatigue cycles, with permanent deformation rate ≤1%.  

Safety compliance certification:  

Passed the strictest fire protection standard for rail transit EN45545-2 HL3 (all items including smoke toxicity, flame retardancy, and heat release meet standards).  

Compliant with TB3139 heavy metal-free environmental requirements.
