Redditch has a long and proud history of mass producing springs stretching back over a 100-years. The spring industry was an off shoot of the needle industry which was a major consumer of wire. The readily available supply of wire lent itself to the development of the spring industry in Redditch. The needle industry has diminished in importance but today Redditch remains the centre for spring manufacturing in the UK. Davies Springs are proud to be a vibrant part of this vital industry.

A spring is a metal object which changes shape in response to an external force and returns to its original shape when that external force is removed.

If a spring is subject to excessive force in relation to the spring it will not return to the original shape.

Extension Spring Definition

An extension spring is a coiled spring whose coils usually touch each other; as a force is applied to stretch the spring the coils separate and the spring lengthens. Typical examples include: – weighing scales, springs supporting a trampoline.

Compression Spring Definition

This is the opposite to an extension spring. The coils are open and are compressed as a pressure is applied. Typical examples are suspension springs in cars, on motor bikes or pedal cycles.

Torsion Spring Definition

A torsion spring works by twisting. – the classic example is the traditional mouse trap. Another familiar example is the counter balance in garage doors. Electronic devices with pop out doors and drawers frequently rely upon a torsion spring.

Conical Springs Definition

A cone shaped compression spring typically found on batteries.
