Extension springs, also known as tension springs, are mechanical components designed to store energy and provide resistance to pulling forces. When stretched, the spring stores mechanical energy and returns to its original length once the force is released. This function allows extension springs to maintain tension between two connected components in mechanical systems.
Our extension springs are manufactured using high-quality materials such as stainless steel, carbon steel, and music wire. These materials provide excellent tensile strength, elasticity, and fatigue resistance, ensuring reliable performance even in demanding working environments.
With advanced spring forming technology and strict quality control, our extension springs offer precise dimensions, stable tension force, and long service life. Different hook types, loop ends, and customized designs can be produced according to customer drawings or specifications.
Extension springs are widely used in automotive parts, industrial machinery, agricultural equipment, fitness equipment, garage door systems, and household appliances.
