Top 10 torsion spring Factory in the world 2025 - Blog

Introduction to Torsion Spring

A torsion spring is a type of spring that works by twisting or torsion. It stores and releases rotational energy when it is twisted or deflected from its original position. Torsion springs are widely used in various industries, such as automotive, aerospace, electronics, and machinery. They are commonly found in applications like door hinges, clothespins, and balance mechanisms, where they provide a restoring force to return a component to its original position after being rotated.
