Custom Torsion Springs: Engineered for Precise Torque and Rotation
This comprehensive display from Zhejiang Zhengna Technology Co., Ltd. showcases our extensive capability in designing and manufacturing a wide array of torsion springs. The assortment includes both standard helical coils and specialized designs with custom leg configurations (straight, hooked, bent, or complex angles). These springs are engineered to store and release rotational energy (torque), providing precise force in a wide range of mechanical applications. Crafted from high-quality materials with a consistent finish, each spring is a testament to our commitment to precision and versatility.
