Spiral Torsion Springs and Wire Forms

Vulcan Spring has produced flat steel constant force springs since 1967. Vulcan has also produced power springs, twin springs and constant torque springs, all made from the same flat steel. Vulcan is now able to produce two new products: Spiral Torsion Springs and Wire Forms.

Spiral Torsion Springs, also produced from flat steel, are characterized by the requirement that their coils do not touch during operation. This type of spring will exert a rotational torque, usually through 360 rotation or less.

The inner end of the spring is typically bent to attach to an arbor or hub. The outer end is then attached to the object that is rotating or utilizing the torque of the spring.

This type of spring can be found in brush motors and in certain applications where a short rotation is required. The torque curve of a Spiral Torsion Spring is linear to the degree of rotation.

Wire Forms of countless shapes and sizes can also now be produced by Vulcan utilizing either flat or round wire steel. These forms are typically used as a tensioning mechanism or to hold objects in place. The ability of these forms to flex and return to their original shape is their defining characteristic.

Vulcan’s highly qualified engineers are able to review your current design or work with a client to achieve the best possible solution. High-speed manufacturing processes ensure fast time to market at a reasonable price.
