Extension springs are typically manufactured with an initial tensionFiwhich presses the coils together in the free state. This fabrication method allows consistent free lengths to be produced, but since the initial tension is not zero, the spring rate is not truly linear when measured from the resting state. However once the initial tension is overcome, the spring does behave linearly.

Flat Springs covers a wide range of springs and forms fabricated from flat strip material which, on being deflected by an external load, will store and then release energy. Flat springs and strip forms are designed to perform functions beyond normal spring functions, e.g. act as a latch, or hold a part in position.

S.M. Spring International has a unique, state-of-the-art multiform equipment, incorporating the latest technology, and can manufacture virtually all kinds of shaped forms for any application.
