Areas of application - Precision springs for demanding industries
Medical technology
Precision, reproducibility and certified quality count for medical applications. Our compression springs and special springs are manufactured in compliance with ISO 13485 e.g. for implant systems, surgical instruments or dosing mechanisms. High reproducibility is crucial for safety and function.
Machinery
In industrial environments, springs must reliably absorb high loads and transmit precisely metered forces. Our technical springs offer uniform spring characteristics and high fatigue strength – ideal for automated systemstest mechanics and modular assemblies.
Valve control systems
Torsion springs and finely tuned torsion springs from u-Flex ensure the operation of complex control mechanisms – for example in injection systemsfluid technology or pressure control systems. Through precise spring calculation we ensure that every movement remains precisely controllable.
Aerospace
In highly sensitive applications subject to thermal, mechanical or corrosive loads, our springs are made from Inconel, titanium or stainless spring steel wire are used. They meet the requirements of ISO 9100 and stand for lightweight construction, durability and absolute reliability – even under extreme conditions.
