Everything You Need to Know About Compression Springs

Compression springs are an essential component in a variety of applications, from electronic devices to industrial machinery. In this article, you’ll learn all about compression springs and their custom manufacturing, covering different types, shapes, materials used, and the advantages of tailored production.

What are Compression Springs?

Compression springs, also known as coil springs or helical springs, are among the most important types of springs. They’re used to exert force when compressed and return to their original form when the force is released. This type of spring is typically cylindrical and maintains a constant wire diameter.

Different Types and Shapes

Compression springs come in various types and shapes to meet the diverse demands of different applications. Here are some of the most common shapes of compression springs:

  • Cylindrical Compression Springs: This is the most commonly used form of compression springs, featuring a consistent diameter throughout their length and frequently used in industrial applications.
  • Conical Compression Springs: These springs taper in diameter from one end to the other, offering progressive spring force, making them ideal for applications requiring varied force.
  • Constant Force Springs: These springs are designed to exert a constant force over a specific length. They’re commonly used in applications like writing instruments, medical devices, and automobiles.

Custom Manufacturing

A significant advantage of compression springs is their customization according to specific requirements. This means that the springs can precisely match the needs of a particular application. From wire thickness, length, and diameter to ends and spring force, all parameters can be adjusted to individual needs.

The manufacturing possibilities for compression springs are extensive. Ground ends are offered in wire thicknesses ranging from 0.30 to 3.00 mm, while unground ends are available from 0.10 to 4.00 mm. Extremely tight length and force tolerances can also be maintained in compression spring production.

Special Materials for Specific Requirements

During the custom manufacturing of compression springs, special materials can be used to meet specific demands. Besides the common spring wires per EN10270, materials like copper, brass, and bronze NE wires can be employed. Additionally, special alloys like Hasteloy, CuNi44, NbZr1, TaW2, and other materials are available upon request.

The use of special materials enables the creation of compression springs capable of withstanding extreme temperatures, aggressive environments, or other unique conditions. This is particularly crucial in fields such as aerospace, medical technology, and the oil and gas industry.

Advantages of Custom Manufacturing Compression Springs

Custom manufacturing compression springs offers various advantages over using standard springs. Here are some of the key benefits:

  • Customized Solutions: Tailor-made compression springs can precisely match the requirements of a specific application, ensuring optimal performance and efficiency.
  • High Precision: Custom manufacturing allows for tight length and force tolerances, ensuring precise spring functionality in the application.
  • Meeting Special Requirements: With special materials, compression springs can be made to meet the unique demands of specific industries, significantly expanding their application scope.
  • Flexibility in Small Batch Sizes: Custom-manufactured compression springs can also be produced in smaller batch sizes, enabling businesses to acquire high-quality springs even with lower demand.

Custom Manufacturing – Including Special Materials Upon Request

Compression springs are a crucial component in many applications and are custom-made according to specific requirements. The various types and shapes offer flexibility and enable optimal performance. The use of special materials expands the application possibilities of the springs, allowing them to operate in challenging environments.
