China Custom Torsion Springs

Compression springs are used in a wide range of products that need pressure control, cushioning, or return force during operation. By compressing under load and recovering their shape after release, they help keep many mechanical systems working smoothly and consistently. These springs are commonly found in automotive components, electronics, hardware, machinery, power equipment, valve and pump assemblies, and other OEM products. Since different applications often have different space, load, and durability requirements, many compression springs are made to custom specifications rather than selected from standard stock. Ningdeli offers this flexibility with wire diameter options from 0.03 mm to 6.0 mm, supporting both sample making and bulk production as a reliable compression spring manufacturer and supplier in China.

Stretch springs are key elastic components that store energy through axial stretching. Typically featuring hook or loop ends, extension springs are widely used in applications that require pull-back force, return mechanisms, or tensioning functions.

Torsion springs store torque energy through radial rotation, enabling mechanical devices to perform functions such as resetting, applying rotational force, and angular positioning. With diverse coil structures and arm-end designs, torsion springs are widely used in precision instruments, automotive components, and household appliances.

Wire form springs are elastic components that are not limited to traditional coil structures. They are made from metal wire through precise bending, folding, winding, stamping, and other processes, featuring flexible structures, diverse functions, and strong spatial adaptability. Wire form springs are widely used in automotive, household appliances, office equipment, medical devices, machinery, smart terminals, and electronic hardware, serving products with special requirements for elasticity, positioning, conduction, clamping, or resetting.

Precision springs, also known as micro springs, feature extremely fine wire diameters, typically between 0.06mm and 1.0mm. With stable force and reliable performance, they are widely used in defense, marine, aerospace, electronics, machinery, electrical equipment, and timepieces. To meet the high demands of precision spring manufacturing, our company operates 24 hours a day using fully automated production lines equipped with some of the world's most advanced technologies.

In the medical world where every tiny component carries immense responsibility, medical springs serve as the essential force core and motion enabler within precision instruments. These are far beyond ordinary metal elements — they embody:

Precision: Manufactured with micron-level tolerances to ensure each deformation remains highly controlled, providing a solid foundation for the stable operation of diagnostic equipment and the reliable performance of therapeutic devices.

Force Transmission: Whether offering continuous gentle support in implantable devices or precisely delivering micro-forces in surgical tools and minimally invasive catheters, medical springs perform with consistent and reliable functionality.

Reliability: Designed for the human body’s complex and demanding environment — temperature variations, bodily fluids, and long-term loads — these springs use medical-grade materials such as high-purity stainless steel and Nitinol alloys, combined with high-cleanliness production, special heat treatments, and advanced surface processing to achieve excellent biocompatibility, fatigue resistance, and corrosion resistance.
