A Compression Spring, just one type of coil spring manufactured by WCS Industries, is an elastic component that stores mechanical energy with helically coiled wires. This type of spring is designed to become shorter when under load. The loops do not touch in the unloaded position and no attachment points are required.

A compression spring is the most commonly used type of spring in manufacturing applications and is the most economically produced. Where there is a variable and opposing force required, compression springs provide the necessary strength. These springs are normally shaped from wire but can also be machined for more demanding applications.

WCS Industries is a compression spring manufacturer who excels in prototype, design and engineering for Original Equipment Manufacturers (OEMs). If your manufacturing needs are new design developments, an existing design enhancement or an evaluation and analysis of a current spring – for over 60 years, WCS has been doing just that.

Several Factors to Consider when Selecting Compression Springs:

  1. Outside Diameter (OD) of the spring
  2. Loading or travel requirements on the compression spring
  3. Compression spring end types
    1. Closed and Ground
    2. Closed and Not Ground
    3. Open and Ground Ends
    4. Open and Not Ground Ends
  4. Material that the spring is manufactured with
  5. Application requirements

WCS Industries manufactures precision compression springs using wire diameters ranging from .005” to .275”. WCS can grind springs to meet squareness specifications down to 1°, well beyond the industry standard of 3°. If necessary, WCS can also hold precise tolerances on loads with capability to 100% gage loads.

Case Study - Two Springs Into One

The Challenge

One of our customers presented us with this request: Combine two compression springs into one. Their custom spring design was to have the first spring work inside a second, larger spring. The unit was time consuming to assemble and the customer was looking for a solution to reduce that assembly time.

Design Criteria

  • Fits-over spec (one end only)
  • Fits-in spec
  • Load 1 @ length 1
  • Load 2 @ length 2
  • Acceptable stress

The Solution

Design one single spring for ease of assembly and complete the task of both springs. WCS Industries' engineers started with the outer spring design first. Using a standard compression spring, we made sure the custom spring design met the loads and fits-in spec. We transitioned the outer spring to the inner spring using a conical design to meet the fits-over spec on the small end of the conical spring. We made a number of prototypes for testing, and the end result was a single custom spring design that met customer requirements and ultimately saved valuable time during the assembly process of the customer's single unit.
