Springs

1. Springs: key elements in many applications

Springs are essential components in a wide range of applications. They store and release energy to exert a precise force, maintain tension or absorb shock. At Sealicone, we offer a wide range of products: conical springs, coilers, leaf springs, tension springs, compression springs and torsion springs. Our aim is to offer solutions adapted to the constraints of each project, whether for industrial, automotive or aeronautical use, or for a more specific application.

The importance of spring selection

The ideal spring is determined by several criteria. Firstly, the nature of the force required (tension, compression, rotation), the range of displacement or the space constraint. Next, we take into account the temperature or the surrounding environment (corrosion, dust). Finally, we select the most appropriate material: stainless steel, high-performance alloy or carbon steel. Sealicone's expertise consists in guiding you through this process to guarantee the reliability and durability of the spring.

2. Sealicone spring types

Conical springs

Conical springs are characterized by their flared shape. Thanks to this geometry, they compress progressively, limiting the space required in the compressed position. They are often found in mechanisms where space is at a premium, and where a controlled compression force is required. Their lateral stability is an asset in avoiding the risk of buckling.

Coil springs

Coil springs (or spiral springs) take the form of coiled metal strips. They release a return force when extended. They are used, for example, in cable winding systems, winding mechanisms or recoil boxes. Sealicone designs customized coil springs, adapted to the desired length and return force, while respecting space constraints.

Leaf springs

Leaf springs are steel or alloy strips, cut and sometimes formed to act as springs. They often support heavier loads and are used in suspension systems, locking mechanisms and electromechanical devices. By adjusting the thickness, width and shape of the blade, the rigidity and stress curve can be fine-tuned to meet the exact requirements of the project.

Tension springs

Extension springs work in extension. They are fitted with loops or adapted ends, which serve to anchor the spring in an assembly. When these loops are pulled, the spring stretches and exerts a return force to return to its initial position. These are found, for example, in garage doors, trap doors and other return systems. Their force depends on wire diameter, number of turns and material stiffness.

Compression springs

Compression springs, on the other hand, work by being crushed. They are common in shock absorbers, pushers and locking mechanisms. In addition to the force exerted in compression, they must sometimes withstand repeated shocks or vibrations. Sealicone offers different dimensions, finishes (zinc-plated, stainless steel) and working tolerances, to cover a wide range of applications.

Torsion springs

Torsion springs act when rotation is applied to their ends. They are often used in clamps, hinges, pedals or return handles. Their design varies according to the angle of winding and torsional force required. The metal alloy chosen must withstand cyclic deformation without altering.

3. Sealicone quality: a complete process

To guarantee the reliability of our springs, we follow a rigorous process:

1. Needs analysis: We study the effort range, the available space, the working angle, the expected number of cycles and the type of environment.

2. Material selection: Stainless steel, special alloys, carbon steel... Each metal has its own advantages in terms of mechanical strength and corrosion resistance.

3. Custom manufacturing: Our winding and cutting equipment enables us to produce any shape (conical, coiled, blade, etc.) and finish (heat treatment, galvanizing, etc.) required.

4. Quality control: We check stiffness, yield strength and torsional properties. On request, we can provide a certificate of conformity or carry out specific tests (fatigue strength, temperature resistance).

Thanks to these steps, our springs meet the technical and normative requirements of each field (aeronautics, industry, automotive, etc.).

Our teams rely on tried-and-tested methods, while keeping abreast of innovations in materials and surface treatments. We look for the best solution for your application.

5. Applications and outlook

Sealicone springs are used in a wide range of sectors:

• Aerospace: opening mechanisms, locking systems, vibration management.

• Automotive: light suspensions, door and trunk actuators, steering dampers.

• Industrial machinery: presses, conveyors, holding, clamping or return systems.

• Everyday equipment: garage doors, security devices, automated closures.

Thanks to ongoing progress in alloys and modeling, springs are gaining in performance and durability. Sealicone has positioned itself as a trusted partner for integrating these advances into your future projects.
