De Spiraal supplies high-quality springs and wire products for applications in defense and aviation, where absolute reliability and precision under extreme conditions are essential. Our compression springs, extension springs, torsion springs and wire shapes are used in locking systems, weapon technology, communication equipment and actuators, among others.
For aviation systems, we develop lightweight and durable suspension solutions that are resistant to high vibrations, temperature changes and long-term stress. In the defense sector, we provide customized components for both vehicles and personal equipment, where safety and functional security are key. Our production meets strict standards in terms of material selection, finish, traceability and documentation. Thanks to a combination of technical expertise, advanced production technology and customer-specific solutions, De Spiral contributes to the operational reliability of critical systems within defense and aviation.
Leaf springs, torsion springs and compression springs fulfil an essential function in defense and aviation systems. Leaf springs are used in the suspension of aircraft and helicopter landing gears, where they effectively absorb shocks. They also provide stability within launch and suspension mechanisms in missile defense systems such as Patriot, THAAD and Iron Dome.
Torsion springs attenuate shocks in the suspension of tanks and armoured vehicles and support control systems. In addition, they compensate for recoil in automatic weapons, which improves precision and recovery time.
Compression springs are indispensable in fighter jets, radar systems and military vehicles. They are used to activate or eject weapons and ensure the stability and protection of vulnerable electronic components against vibrations.
Each type of spring thus contributes to the reliability, control and safety of systems that have to perform under extreme conditions.
At De Spiraal, we go further than just producing springs; we think along, from the drawing board. Do you want to optimize an existing spring for better military performance? Would you like advice on developing a completely new design? Or do you need a specialist who thinks along with you, from prototype to end product? Then you've come to the right place.
With our own engineering department and years of experience in the defense and aviation sectors, we are happy to work together on a suitable, sustainable solution, fully tailored to your application.
Applications in this sector require lightweight and resilient solutions, such as leaf springs, constant force springs and torsion springs for controlled movements.
