At Leeming & Peel we are manufacturers of quality tension springs with a choice of any of the following; loops, hooks, extended, swivel or apply inserts to meet any application.
The type of wire will depend on the application of the spring. Different materials work in different ways, contracting and extending at different rates. Our years of expertise enable us to advise which material best suits your application, which can often result in money saving options.
In this video you can see our state-of-the-art precision Wafios CNC coiler in action manufacturing an extension spring. It can also coil torsion springs, double torsion springs, shaped conical springs, compression springs and wireforms.
The spring featured in the video is an extended hook tension spring made from 1.63mm Carbon Spring Steel. It has an Outside Diameter of 12.7mm with a body length of 57.4mm. The hooks are set at 90 degrees. Once the spring comes of the machine a second operation is required to bend the final hook into place.
The CNC machine has been programmed to ensure every spring is the exact same specification as the previous one. The Wafios uses laser technology for precision cutting. The red laser light can be seen clearly in the video following the coiling of the spring.
