Compression Springs

Compression springs are the most easily recognizable mechanical springs. The straight, cylindrical shape with closed ends is a very common design, but there are many other possible shapes we can use for different projects. In basic terms, a compression coil spring is designed to store energy or resist the force applied along its axis. The spring is at rest in an extended position, and it will contain a specified amount of energy as it is compressed until it begins to push back with its recoiling action.

Custom Compression Springs:

Coiling Technologies, Inc. can produce a compression coil spring for a variety of applications. We manufacture custom compression springs in a wide range of shapes and configurations. Although compression springs usually feature uniform spacing of each coil, Coiling Technologies can also produce compression springs with multiple pitch diameters to meet more demanding requirements. We can also design compression springs in conical, hourglass, and barrel shapes to suit your individual requirements.

Designing Compression Springs:

Compression springs suppliers must have the ability to meet all your requirements, no matter how big or small the project. When you work with the spring design professionals at Coiling Technologies, we will help you optimize your compression coil springs to meet the project’s requirements.


Key Parameters

  1. Free Length of Compression Springs
    1. Length of Compression Springs prior to any force being exerted on it.
  2. Wire Diameter of Compression Springs
    1. Diameter of the round, square, or rectangular material used in manufacturing of Compression Springs
