Metal Extension Springs, For Industrial Use, Certification : ISI Certified

Extension springs are commonly attached at both ends to other components and are used to create resistance against linier tensioning forces or pulling forces. These springs can be supplied with open hooks, closed eyes or various other forms of attachment on the ends and they can normally be made complete on a CNC spring forming machine. The weakest point of a Tension spring is where the body of the spring forms into the hook or eye; however there are several design methods that we can employ to resolve this issue, ensuring high quality Tension springs to meet your demands.
