Precision Engineered Springs


  • Compression Springs -  Helical compression springs are used to resist applied compression forces or to store energy in the push mode. They have the most common spring configuration and are found in many applications such as automotive, aerospace and consumer goods. 



  • Extension Springs - Helical extension springs store energy and exert a pulling force. Usually, they are made from round wire and are close-wound with initial tension. Typical applications include balance scales, toys, garage doors and various types of spring tensioning devices.



  • Torsion & Double Torsion Springs - A type of spring that transmits torque in machines by bending in one or two directions, depending on the type of torque needed.



  • Clock/Power Springs - Clock springs are made from flat stock and coiled like a snail shell, each coil nesting inside the next larger one. They typically work inside a housing and exert torsional force against either a central shaft or the housing itself.



  • Leaf/Flat Springs -  A leaf spring is a long, flat, and flexible piece of spring steel or composite material that resists bending. The basic principles of leaf spring design are relatively simple, dating back to use during medial times. Below is a picture of the MRAP (Mine Resistant Ambush Protected) vehicle which uses a multitude of leaf springs. Liberty Spring produced thousands of leaf springs used for these vehicles in Iraq and Afghanistan.



  • Wire Forms, Clips & Rings - Wire Forms are designed with a wide variety of shapes to perform many functions. Wire forms are often used as links to carry loads with a minimum deflection, or as rings and clips to holds parts in place.
