Generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc.

During the production process of the spring, the spring needs to be quenched and polished. The purpose of spring quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then temper with different temperatures to greatly improve the rigidity, hardness, and durability of the steel. Wear resistance, fatigue strength and toughness, etc., so as to meet the different requirements of various mechanical parts and tools. After the spring is formed, burrs will remain at both ends, which will affect the appearance and installation accuracy of the spring.
