NVH protection in military electronics. Technical foams for communications racks
A fractured solder joint on a tactical radar’s motherboard can leave an entire battalion blind. The true enemy of military electronics is not always enemy fire; often, it is the constant vibration of the armoured vehicle itself during deployment in hostile terrain.
To protect communications and optronic systems from this silent form of wear and tear, we have perfected the use of high-dissipation technical foams
Material fatigue and mechanical limits
Server racks mounted in tracked or wheeled vehicles are subjected to constant punishment. Traditional rubber mounts or metal damping systems have limited resonant frequency capabilities. When an armoured vehicle traverses rough terrain at high speed, these systems transmit secondary harmonics that eventually cause cracks in sensitive components.
At ZFoam, we solve this structural issue by replacing rigid mounts with cradles made of viscoelastic foam and high-density cross-linked polyolefins.
The material absorbs the vibration.
The circuit survives.
Energy dissipation and anti-static protection
Our materials engineering expertise allows us to machine housings that isolate equipment across all three spatial axes. The material absorbs kinetic energy from both low and high frequencies before it can reach printed circuit board solder joints.
Transporting military hardware also demands absolute control over electrical discharges. We integrate conductive and ESD-dissipative foams that encase the component in a protective cage. This diverts any charge generated by transport-related friction, eliminating the risk of frying processors.
CNC prototyping for defence contractors
Major optronics and telecommunications manufacturers cannot base their system designs on standard catalogues. Each rack has a unique centre of gravity and requires a custom fatigue analysis.
Our CNC machining capabilities allow us to mill the exact geometry of the housing in 2D, without requiring the client to invest in initial tooling or moulds. We evaluate equipment weight and vehicle vibration frequencies to select the precise foam density that guarantees true tactical protection.
This adaptability enables us to meet stringent international standards and support the supply chains of leading sector contractors.
Ensure system operational readiness.
Communication equipment failure due to vibration is a sign of poor integration design. Partnering with a specialist in foam engineering allows you to safeguard your system’s reliability right from the blueprint stage.
