High-performance products for the defense industry

Structural noise, shock, and vibration damping
Defense applications are among the most demanding when it comes to structural noise, shock, and vibration damping.
For decades, we have been an approved supplier for the German, Belgian, and Dutch Navy, offering the following product range:
- Cable spring mounts for shock and vibration isolation, with a static load range from approximately 30 g to several tons.
- Sandwich G Reduce, meeting AECTP 400 vibration and shock standards, effectively dissipating over 80% of impact energy.
- Rubber springs and elastomer mounts for shock and vibration isolation, with a static load range from 20 kg to 2,500 kg and a dynamic deflection of over 120 mm.
- Rubber springs and elastomer mounts for structural noise reduction in submarines.
- ATM pipe clamps, designed to minimize structural noise.
- Specialized tools for large diesel engines and naval applications.
