Springs are critical components in many industrial products and mechanisms, for example, in mobile work machines and security-related products. For a spring to function reliably and withstand the intended load, a number of circumstances need to be considered in the design and manufacture. 

Support for spring design

We will help you with spring design, dimensioning, material choices, and technical solutions, thereby making sure the spring meets the requirements of its intended application and functions reliably even in demanding environments. We also manufacture model series and prototypes to support product development, allowing the functionality of different spring solutions to be tested before serial production. In addition, we deliver spring solutions flexibly, from small batches to large series, owing to efficient manufacturing and a broad range of materials.

A wide choice of springs and spring components

We offer a comprehensive range of springs and spring components for various industrial applications. We have decades of experience in manufacturing springs and wire products. In addition to customized spring solutions, we supply standard springs promptly available from our Spring Store.

Technologies, materials, and aftertreatments

The basic technologies for spring manufacture are spring wire twisting and wire bending. These technologies are used to manufacture various customized springs, such as compression springs, extension springs, torsion springs, and wire forms.  

Spring materials are chosen according to the load, environmental conditions, and durability requirements of the intended use. Through the right choices, the spring solution can be optimized in terms of corrosion resistance, electrical conductivity, or light weight, for example.

Aftertreatments can be used to improve the durability, performance, and service life of the spring, as well as to ensure its functionality under demanding operating conditions.

Typical examples of aftertreatments include:

• thermal treatment and hardening to improve material properties
• shot blasting and prestressing to increase the fatigue resistance of the spring
• grinding, coating and painting to finish and protect the spring

Customized spring solutions

We manufacture springs according to the customer’s drawings or requirements of the operating environment and assist with spring design and dimensioning, if required. 

We manufacture springs in the following range of wire thicknesses:

• Customized compression springs 0.1–12.0mm
• Torsion springs and wire forms 0.1–8.0mm

Standard springs promptly from stock

Our extensive stock product range includes thousands of standard springs and spring components that can be delivered promptly to meet various industrial needs. More than 8,000 product items are available; delivery from our Spring Store may even be possible on the same day.

Design considerations

Different spring types have their own characteristics that affect design and dimensioning. By taking these into account already in the early stages of product development, the spring can be designed to ensure proper function, installability and durability in its intended application.

Compression springs
In addition to spring force and spring rate, the design should take into account the available installation space, maximum load and required service life. The spring geometry and end configuration also affect performance and durability.

Extension springs
The end loops are critical points in the structure of an extension spring. Their resistance to stress and a loop design suitable for the application should be considered already at the design stage.

Torsion springs
When a torsion spring is loaded, its inside diameter decreases. Sufficient clearance must therefore be left between the spring and the shaft throughout the full range of movement.

Wire forms
Two- and three-dimensional wire forms can be designed for applications such as locking and fastening elements, contacts, handles and holders. Prototypes can be produced quickly, enabling flexible testing of different solutions during product development.
