Extension springs, commonly referred to as tension springs, are designed to operate under tensile load and provide resistance when pulled apart. These springs store mechanical energy during extension and return to their original shape once the external force is removed. This function helps maintain a consistent pulling force between connected components in various mechanical assemblies.
Our extension springs are produced from premium materials such as stainless steel, carbon steel, and music wire. These high-quality materials ensure excellent strength, flexibility, and long fatigue life, allowing the springs to perform reliably in both light-duty and heavy-duty applications.
Using advanced spring coiling equipment and precise manufacturing processes, we ensure accurate dimensions, consistent spring tension, and stable product quality. Various end configurations, including hooks, loops, and customized designs, can be manufactured according to customer drawings or technical requirements.
Extension springs are commonly applied in a wide range of industries, including automotive components, industrial machinery, agricultural equipment, fitness devices, garage door mechanisms, and household appliances.
