//Compression Springs

Compression Springs

Compression springs are the most common spring configuration that product manufacturers turn to when enhanced product functionality is desired. Used in automotive, aerospace, general industrial, medical and technology products, this spring type is used to resist applied compression forces or to store energy in the push mode. In more simple terms, compression springs contain the highest potential energy when the component is “compressed.”

Spring Materials

Compression springs can be manufactured from a variety of materials, though predominantly from carbon and stainless steels. While a number of spring geometries are possible in any material, choosing the correct metal alloy for your application can involve a number of factors from ambient temperatures, corrosive environments, and even the normal weather patterns where the springs will be used.

Depending on the size of the material necessary to produce your solution, MW Industries has the ability to manufacture compression springs from cold-coiled wire or hot-wound bar stock.

Cold-Coiled

Wire diameter: 0.004″ – 0.625″

Hot-Wound

Bar stock diameter: 0.625″ – 1.875″

Compression Spring Manufacturing

Springs are made on state-of-the-art CNC compression coiling equipment that uses vision and laser statistical process control systems to sort and adjust the free length. By investing in high-end coiling equipment, MW Industries is able to improve the compression spring quality and ensure that fewer springs are rejected for not meeting specifications.

After the coiling process, the compression spring has to be hardened or heat treated to allow the steel to maintain its resilience. MW Industries has stress-relieving ovens for hot or cold wound springs which meet all national heat-treating standards.

The compression spring then goes through various finishing processes.

  • Grinding – Ensures the compression spring has a flat end.
  • Shot Peening – Process by which the surface of the spring is exposed to tiny steel balls to strengthen the steel, and consequently resist fatigue and cracking when the spring is flexed.
  • Setting – Fully compressing the spring, so that all the coils touch each other, to fix the desired length and pitch.
  • Coating – Covering the spring with paint, rubber, or another metal (such as zinc or chromium) in order to color code and/or prevent corrosion.
