Torsion spring is usually divided into left-handed or right-handed, and more complex double torsion spring. When the spring arm of torsion spring is twisted, it will produce elasticity and torque. According to different environment and application, torsion spring can adopt many different materials and flexible design. By adjusting the outer diameter, wire diameter, arm angle and number of turns of the spring, we can obtain almost unlimited spring sizes and torques. At present, our customized torsion spring can produce wire diameters ranging from 0.20 mm to 5.00 mm. Torsion springs can be divided into industrial machine spring, industrial valve spring and stainless steel torsion spring according to their different uses. Xinyi spring has long-term experience in the development, design and production of all kinds of torsion springs and different materials, and continuously pays attention to the improvement of production process. Our core competitiveness is reflected in the spring product design and development capabilities, strict quality control, good delivery and service, all our efforts to meet your needs of construction machinery spring.
