Areas of application for our spiral springs - For industries with the highest requirements
Medical technology
Precision, reliability and biocompatibility are important for applications in surgical instruments, implants or medical devices. Our springs meet the requirements of ISO 13485 and guarantee safe function even with very small spring travels or minimal forces.
Machinery
In industrial plants, machine tools or robotic systems, our spiral springs ensure stable force transmission and a long service life. They offer high repeat accuracy and are ideal for automated production processes in which peak loads need to be controlled.
Valve control systems
u-Flex supplies precise spring solutions for injection valves, control applications and safety mechanisms. Precise calculations, coordinated spring constants and precisely fitting geometries result in reliable components that can be used in complex control circuits.
Aerospace
Wherever low tolerances, extreme temperatures and low-vibration designs are required, manufacturers rely on our spiral-machined high-performance springs. The materials used, such as titanium or Inconel, and our ISO 9100-compliant production ensure function and service life in the most demanding systems.
Why customers choose u-Flex
As a specialist in high-precision spiral springs, u-Flex offers more than just standard solutions. Our customers rely on genuine partnership, technical understanding and a transparent way of working – from the idea to series production.
Highest manufacturing precision with tested quality
Our spiral springs meet the highest demands in terms of shape accuracy, reproducibility and load capacity.
