Coil Spring Air Compressors

Coil Spring compressors usually resist when force is applied, thereby compressing energy and releasing it for shock absorption purpose or to provide a cushion between two connecting surfaces.

You will usually find coil spring compressors being used in automotive, aerospace and consumer applications.

A coil spring comes in open helical shape and is purposely curved at a specific dynamic cylinder measurement. Coil springs with a diameter of three-eights inch are cold coiled while those with a diameter over five-eights inches are hot coiled.

What is a good coil spring?
Hot-coiled springs are usually used as industrial compressors in the transportation industry and construction equipment builders. These springs are made from specially produced bars of either carbon or alloy steel, thereby ensuring complete surface smoothness and a high level of quality standards.

Besides being made from really good quality material, it is also important that the hot-coiled spring is usually preset. This helps in allowing the spring to support more weight and load, which would otherwise be difficult if the spring is not predefined.

However, there is one drawback with presetting the spring and that is it can reduce its service life. This happens due to both stress and hardness on the spring bars. But, not too worry much, as shot preening can extend the service life.

Some kind of protective finish is required as rust can lead to pitting, which would eventually end up destroying the coil spring. Applying a layer of protective coating depends on the climate of a place, however in most cases commonly used coatings or calcium or zinc plating is smeared on the surface.

What to look for in a coil spring compressor?

It is important that compression springs are stress-relieved in order to remove residual forming stresses. The stress relieve depends on the design and space limitations. Listed below is the different level of stress levels:
