Spring Widely Used

- Mar 27, 2018 -

Although the spring industry is a small industry in the entire manufacturing industry, its role can never be underestimated.

The country’s industrial manufacturing and automobile industries must accelerate development, and the spring industry, which is one of the basic components and parts, needs even more of a period of development to adapt to the rapid development of the country’s entire industry. In addition, the expansion of the spring product variety and the improvement of the quality level are also the needs of the replacement of mechanical equipment and the need for the improvement of the supporting host performance. Therefore, the development of the entire country's industry, spring products play an important role.

Daily necessities and hardware industry, including lighters, toys, locks, door hinges, gym equipment, mattresses, sofas, etc. In terms of quantity, the demand for springs is the largest, in the hundreds of billions.


According to the nature of the force, the spring can be divided into a tension spring, a compression spring, a torsion spring and a bending spring. The shape can be divided into a disc spring, an annular spring, a plate spring, a coil spring, a truncated cone vortex spring and a torsion bar spring, etc. According to the production process can be divided into cold coil spring and hot coil spring. Ordinary cylindrical springs are widely used due to their simplicity of manufacture and their ability to be manufactured in various types according to loading conditions.

Spring manufacturing materials generally should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, commonly used carbon spring steel, alloy spring steel, stainless spring steel and copper alloys, nickel alloys and rubber Wait. Springs are manufactured by the cold roll method and the hot roll method. The cold coil method with a spring wire diameter of less than 8 mm and the hot coil method with a diameter of more than 8 mm. Some springs are also subjected to strong pressure or shot peening after they are made, which can increase the bearing capacity of the spring.
