Extension Springs:

Extension springs are closed coiled helical springs that function in the opposite manner of compression springs. In other words, the applied axial force is exerted to pull the extension spring apart instead of pressing it together. The rest of the design specifications are generally the same, and extension springs have many options for the wire diameter, mean diameter and number of coils used to determine the extension rate.

Custom Extension Springs

Extension springs can easily be employed for many purposes and applications, and we can design the end configurations and pitch requirements that match your individual needs. Coiling Technologies has the experience and equipment to create the extension spring end configuration you need and the initial tension requirements that will keep it functioning properly. Coiling Technologies uses high-tech CNC-controlled lathes and auto coilers to make sure the initial tension will be consistent on every spring we make.
