From a clothes peg to a heavy lifting hinge, Torsion springs are versatile and have many different applications. Torsion springs operate through rotational force, with legs/tangs that generate torque when twisted around the spring's central axis, often seated on a mandrel (shaft or rod) to stabilise the spring in the application. As a specialist UK manufacturer, we create custom torsion springs to your exact specifications and requirements.
Standard, catalogue torsion springs will come with various leg lengths that are usually straight. The coiling direction of the torsion spring can also be changed for a better product/application fit. Custom torsion springs can be designed to exactly fit all your mating parts within the application. Adding complex leg configurations and the exact movement and force to your design requirements means that Flexo can supply a well designed, long lasting solution.
