What is a thin extension spring?
Thin extension springs are slender, cylindrical springs that are placed under tension when they are extended. They store energy during extension and release it as soon as the load is removed. Due to their small wire diameter, they are particularly well suited for applications where precision, sensitive return movements and very limited installation space are key.
Applications of thin extension springs
Thin extension springs are suitable for a wide range of applications where limited space, light forces and high precision are required. Their slim design makes them ideal for sensitive or miniature mechanisms.
- Medical: In medical devices such as dosing pumps, injection mechanisms and laboratory instruments, thin extension springs provide controlled return motion and light tension build-up. Their high precision and reliability are crucial in this demanding sector.
- Mechanical Engineering: In machinery, thin extension springs enable controlled movements of levers, valves and guides. They offer a compact and reliable solution for precise functional movements.
- Defence & Aerospace: For applications where weight, size and reliability are critical – such as actuators, clamping systems and sensor components, thin extension springs provide a lightweight solution with consistent performance.

The result is always a spring that fits your application perfectly.
Our production takes place under strictly controlled conditions using certified materials, ensuring both quality and delivery reliability. Whether you need a prototype or a large series, we deliver quickly, flexibly and fully customised. Choose De Spiraal and you choose a technical solution that works.
Benefits of thin extension springs
Thin extension springs from De Spiraal are fully tailored to the technical requirements of your application. Thanks to our material expertise and production capabilities, we can always provide a solution that both functions and fits.
- Constant spring force and high precision: Tight tolerances and careful material selection ensure that our springs retain their properties, even under repeated loading in sensitive systems.
- Fully custom-made: We design every spring based on your specifications, including hook or loop forms, working range, spring rate and material requirements, from one-offs to large series.
- Suitable for light loads and compact applications: Due to their fine wire diameter, our thin extension springs are ideal for applications where space and tensile force are limited, without compromising on reliability.
- Available in various materials: Depending on the environment and load, we work with you to select the most suitable material, such as stainless steel, phosphor bronze or heat-resistant alloys.
- Consistent performance, even in series production: Whether you require a prototype or thousands of units, our springs always meet the same strict quality standards.
