Torsion Springs

Torsional springs are classified into two types: single torsion and double torsion. The spiral spring is the one that uses a torque, or stores rotational energy. A torsion spring is traditionally mounted around a shaft or pivot supported by three or more points, and are easy to install thanks to the variety of end types available.

Torsional springs are mainly used in curtains, door hinges and electrical appliances. Wires used to make these springs are often rectangular or circular in shape, while the curved rectangular wire is able to effectively withstand stress.

Spring materials

KLF chooses torsion spring material according to the spring application, weather, temperature and other factors, and primarily uses brass and stainless steel as the raw materials. We can also treat these springs with zinc plating, chromium plating, nickel plating, tin plating, copper plating and other surface treatments.
