Industrial Springs

lee springs

There are a number of different industrial springs available on the market today each with their own set of unique characteristics and applications. Compression springs, extension springs, torsion springs and wire forms are just some of the springs being manufactured.

Compression Springs

Compression springs are helical springs with an open coil and are the most common form of spring. These coil springs are most often used to place over a rod or to fit into hole. When load is placed on the compression spring it will shorten in length and push back against the load as it strains to return to its original length.

There are many issues that need to be considered during the design and manufacture of compression springs. These include manufacturing tolerance requirements, slenderness ratio, deflection and the squareness of the spring’s ends.

Extension Springs

The job of an extension spring is to store and absorb energy in addition to creating a resistance. The tightness of the spring’s coil is determined by the initial tension of the spring - the tension can be adjusted to suit the needs of the application of the spring.

Torsion Springs

Torsion springs are helical springs. This type of spring exerts a torque when the ends of the spring are hooked onto other components. These springs can store and release energy and can be designed to operate in an anticlockwise or clockwise direction.

Torsion springs are best suited to applications that require torque to be applied from two directions. These springs work at their maximum capacity when supported over a rod or tube.

Wire Forms

Wire forms are used on many different components from s-hooks to paper guides. These types of fitting can often be manufactured with any specialist machinery being required.
