1. Springs: essential components for demanding applications

Springs are critical components in many mechanical systems. They store and release energy to apply a controlled force, maintain tension or absorb shocks. Sealicone offers a broad range including conical springs, constant-force and recoil springs, leaf springs, extension springs, compression springs and torsion springs. Our objective is to provide solutions tailored to each project’s constraints, from industrial and automotive systems to aerospace and other specialized applications.

Selecting the right spring

The correct spring is defined by several parameters: the type of load required (extension, compression or rotation), travel range, available space and operating environment. Temperature, corrosion and contamination may also influence the design. Material selection is equally important, including stainless steel, carbon steel and high-performance alloys. Sealicone supports customers in defining the right combination to achieve reliable and durable performance.

2. Main spring types available from Sealicone

Conical springs

Conical springs use a tapered geometry that allows progressive compression and can significantly reduce the solid height. They are well suited to mechanisms with limited available space and controlled compression requirements. Their geometry also improves lateral stability and helps reduce buckling risk.

Recoil and constant-force springs

Recoil springs are commonly manufactured from coiled strip material and generate a return force when extended. Typical applications include cable-retraction mechanisms, rewind systems and return devices. Sealicone can tailor these springs to the required travel, force and available installation envelope.

Leaf springs

Leaf springs are flat strips of steel or alloy cut and formed to provide elastic behavior. They can withstand significant loads and are used in suspension systems, locking mechanisms and electromechanical devices. Thickness, width and geometry are adjusted to achieve the required stiffness and load curve.

Extension springs

Extension springs operate under tensile loading. Their hooks, loops or other end features allow them to be anchored into an assembly. When extended, the spring generates a return force that brings the mechanism back toward its initial position. Spring rate depends on wire diameter, coil count, geometry and material properties.

Compression springs

Compression springs operate by being compressed. They are widely used in shock-absorption, actuator, valve and locking mechanisms. Depending on the application, they may also need to withstand repeated impact and vibration. Sealicone can provide different dimensions, materials, finishes and operating tolerances.

Torsion springs

Torsion springs generate torque when their legs are rotated. Typical applications include clamps, hinges, pedals and return handles. Design depends on the required angle, torque, number of cycles and installation geometry. The selected alloy must withstand repeated deformation without loss of performance.

3. Sealicone quality: a complete process

To ensure spring reliability, we follow a structured process:

  1. Requirement analysis: load range, available space, working angle, expected number of cycles and operating environment.

  2. Material selection: stainless steel, special alloys or carbon steel depending on mechanical, thermal and corrosion requirements.

  3. Custom manufacturing: coiling, cutting and forming equipment is selected according to the required spring geometry and finish, including heat treatment or protective coating where applicable.

  4. Quality control: stiffness, elastic limit, dimensions and torsional properties can be verified. Certificates of conformity and specific tests such as fatigue or temperature testing can be supplied on request.

This process enables our springs to meet the technical and regulatory requirements of aerospace, industrial, automotive and other demanding sectors.

4. Why work with Sealicone?

  • Expertise: experience with a wide range of alloys and spring geometries.

  • Flexibility: from prototypes and small batches to serial production.

  • Customization: specific hooks, loops, ends, coatings and finishes can be incorporated to improve integration and service life.

  • Engineering support: assistance from design through validation, including trade-offs between space, force, durability and production cost.

Our teams combine proven manufacturing methods with ongoing monitoring of developments in materials, surface treatments and design tools to identify the best solution for each application.

5. Applications and future developments

Sealicone springs are used across many sectors:

  • Aerospace: opening mechanisms, locking systems and vibration-management devices.

  • Automotive: lightweight suspension components, door and tailgate actuators and steering mechanisms.

  • Industrial machinery: presses, conveyors, holding, clamping and return mechanisms.

  • General equipment: safety devices, automated closures and numerous mechanical assemblies.

Continuous progress in alloys, surface treatments and simulation enables springs to achieve higher performance and longer service life. Sealicone supports customers in integrating these developments into future projects.

6.结论

Springs provide an efficient way to manage force, motion and energy absorption in mechanical systems. The wide range of available geometries—conical, recoil, leaf, extension, compression and torsion—makes it possible to address very different constraints.

Whether you are developing a prototype, a small series or a high-volume product, Sealicone can support the design and manufacture of springs tailored to your specifications and sector requirements.
