The product range of Changzhou Sanikang Spring Making Co., ltd covers torsion springs, conical springs, compression springs and other categories, including single-torsion, double-torsion and special-shaped torsion springs, conical springs with different tapers, and compression springs in various diameters and lengths.

Torsion springs come in a rich variety of structures, differing in coil configuration, leg length, leg direction and overall shape. The company determines dimensions and inspection requirements according to product structure, installation space and loading needs, and arranges corresponding production.

Conical springs feature a tapered or tower-like structure. By adjusting outer diameter, inner diameter, free height and number of coils, they can fit different assembly spaces, offering flexible options for products requiring gradually changing diameters or controlled compressed height.

Compression springs are one of the fundamental categories in the company's precision spring product line. Wire diameter, coil diameter, length, load and travel can be adjusted for different application needs, while process control maintains dimensional and performance stability.

The company's testing center is equipped with fully automatic spring tension/compression testing machines, a fully automatic spring torsion testing machine, a 0-5000 N tension/compression tester, profile projectors, fatigue testing machines and salt spray test chambers, providing appropriate testing conditions for different types of spring products.
