Product Application

Transportation

Automotive industry: Used to manufacture automotive suspension system springs (such as shock absorbing springs), valve springs, clutch springs, etc., to ensure the smoothness and safety of vehicle driving. Rail transit: Spring components in high-speed trains, subways, trams and other rail transit vehicles, such as bogie springs, are used to mitigate shocks and vibrations during operation.

Mechanical equipment and instruments

Industrial machinery: Steel springs in various mechanical equipment, such as press springs, compressor springs, mold springs, etc., are used to realize automatic reset, energy storage or shock absorption of equipment. Instruments and meters: Springs are used as elastic sensitive components in measuring instruments, such as pressure gauges, spring scales, etc., to convert physical quantities (such as pressure, weight) into measurable mechanical displacement or deformation.

Building and bridge engineering

The metal spring steel such as suspension cable and stay cable in the bridge structure is used to adjust and support the bridge structure, so as to enhance the stability and safety of the structure. In the seismic design of buildings, spring shock absorber is used to reduce the damage of buildings caused by earthquakes.

Advantageous Features

High elastic limit

One of the core characteristics of spring steel is that it has a very high elastic limit, that is, it can withstand a large stress before a significant permanent deformation occurs, which allows the spring to quickly deform under external forces and return to its original form.

Good fatigue resistance

Because the spring will experience repeated loading and unloading process during use, the spring steel sheet metal must have good fatigue resistance to ensure long-term stability and reliability.
