Compression Springs

Ace Wire Spring & Form designs and manufactures custom compression springs to the exact requirements of our customers’ needs. Compression springs are open coiled helical springs that resist a compressive force applied axially. They may be tapered, conical, cylindrical, convex or concave in shape. The changing of the ends, direction of the helix, material and finish allows the springs to meet a variety of specially designed needs.

What are Compression Springs?

A type of wire spring used in everything from appliances to motorized equipment, motors, and more, compression springs are compressed by a load acting upon them or their ends. The design of the wire attempts to return it to its original shape, thus pushing the load back. They are designed and used to resist applied compressive forces or to store energy in the push mode. Typically, they are cylindrical helical made out of round wire. However, they can be made conical, oval, barrel-shaped, or virtually any other shape. The wire can also be round, square, or rectangular. This is the most common configuration and is found in many applications such as automotive, aerospace, consumer goods, and custom gun springs.

One can control the actions of compression springs by how they are designed. The diameter of the coil, the number of coils, the style of the ends, even the length and diameter and shape of the wire, can all make different designs. This is why it is so important to have all the right dimensions when ordering so its performance will meet the needs of the application.

Compression Spring Types

Compression Springs are open-coil helical springs that offers resistance to a compressive force applied axially. Helical compression springs are used to resist applied compression forces or to store energy in a push mode. Compression springs have the most common configuration and are most commonly used in automotive, aerospace and consumer applications. Most compression springs are a straight cylindrical spring made of round wire. Ace Wire Spring & Form, a manufacturer of compression springs produces a variety of compression types, shapes, and specific specifications. Click here for compression springs specifications.

Compression springs from a manufacturer come in a variety of types including: Conical Compression, Barrel, Hourglass and Cylindrical shapes and may have various spacing or no spacing at all between coils.

Wire Selection: rectangular, round, square or special-section. Round being the most adaptable.
Compression Spring Mandatory Specification: the functional design characteristics.
Compression Spring Secondary Specification: the secondary characteristics, which is useful for reference and should be considered advisory data.
Dimensional Limits: governed by the space allotted with regard to allowable solid height and outside and inside diameters.
Spring Stress Level: determined by the dimensional limits together with the load and deflection requirements. Our compression springs are stress-relieved to remove residual bending stresses produced by the coiling operation.

How to Determine Rate for Compression Springs

For Compression Springs – Rate which is the change in load per unit deflection, may be determined by the following procedure:

  1. Deflect spring to approximately 20 percent of available deflection and measure load (P1) and spring length (L1).
  2. Deflect spring to approximately 80 percent of available deflection and measure load (P2) and spring length (L2). Be certain that no coils (other than closed ends) are touching L2.
  3. Calculate rate (R) lb./in. (N/mm) R = (P2 – P1) / (L1 – L2)
Solid Height of Compression Springs

The solid height of compression springs is defined as the length of the spring when under sufficient load to bring all coils into contact with the adjacent coils and additional load causes not further deflection. Solid height should be specified by the user as a maximum, with the actual number of coils in the spring to be determined by the spring manufacturer. As square or rectangular wire is coiled, the wire cross-section deforms slightly into a keystone or trapezoidal shape, which increased the solid height considerably. The dimensional change is a function of the spring index and the thickness of the material.
