Dukan zane, daga yadda aka raunata maƙarƙashiya zuwa siffar ƙugiya a kowane ƙarshen, is focused on one simple goal: providing a reliable and consistent pulling force. Understanding how these components work together is the key to using them safely and effectively in any machine or product.

How is Initial Tension Created in an Extension Spring?

You pick up an tsawo spring[^1], and its coils are pressed tightly together. Even before you stretch it, there is a hidden force holding it shut. What creates this?

Initial tension is an internal force created during the manufacturing process. As the wire is coiled, a slight twisting force is applied, pressing each coil tightly against the next. This built-in tension must be overcome before the spring even begins to stretch.

A cikin makamanmu, controlling tashin hankali na farko[^2] is one of the most critical quality checks we perform. It is the difference between a spring that feels "snappy" da amsawa, da wanda yake jin kasala da rauni. Wannan karfi ba hatsari ba ne; it is a carefully calculated part of the spring's design. Yana ba da damar bazara don tallafawa kaya ba tare da wani juyi na farko ba, wanda yake da mahimmanci ga aikace-aikace kamar trampoline[^3]s ko kofofin allo[^4] inda kake son dawowa nan take da zarar tsarin ya huta.

Idan wannan lanƙwasawa yayi kaifi sosai, it creates a weak spot that will fail from metal fatigue after repeated use. The type of hook—whether it is a simple crossover hook or a more robust machine hook—must be chosen based on the load it will carry and the component it will attach to. A well-designed hook ensures the spring can deliver its force reliably for thousands of cycles.

Designing a Reliable Connection

The hook's geometry and manufacturing process are just as important as the spring's coil body.

• Damuwa Matsi: Any sharp bend in a piece of metal creates a point where stress is amplified. The hook of an tsawo spring[^1] has several of these bends. Good design aims to make these bends as smooth and gradual as possible to distribute the stress over a larger area, which greatly increases the spring's fatigue life.
