What's Extension spring?

Extension springs are made from different qualities of wire and are tightly coiled and usually made in round, cylindrical sections. To use an extension spring, you must attach the ends to two components. If the components try to pull apart from each other, the extension spring will force them back together. The typically feature of tension spring is a hook or loop on each end. The hook types of extension springs usually finished as crossover center hook, extended hook, Machine hook, side hook, and so on. Tension spring occupies an important position in the global market and is widely used in national defense, computer, electronics, automobile, medicine, biochemistry, aerospace, railway, nuclear power, wind power, thermal power, engineering machinery, mining machinery, construction machinery, elevator and so on.



How Extension Springs Work?

An Extension Spring is activated when a linear force is applied along the length of the coil, which will stretch it open. The spring's initial tension is created by resisting the "stretch". As the spring tries to maintain or return to its original shorter length, it utilizes the force created by the tension.
