A spring is a mechanical component that uses elastic deformation to store and release energy. It is usually made of round cross-section material, with the coils in close contact when unloaded. The spring generates elastic force through stretching, used to control the movement of parts, store energy, or measure the magnitude of force.
Valve springs are springs specifically designed for valve mechanisms. They utilize elastic deformation to achieve valve opening, closing, or regulation. They are typically installed on the valve stem or seat to provide the necessary elastic force to ensure valve sealing and operational stability.
A high-temperature spring is an elastic component that can maintain stable performance in extreme high-temperature environments. It is widely used in aerospace, automotive, metallurgy, chemical and other fields. Its core characteristics are the ability to maintain good elastic deformation capability under high-temperature conditions, while also possessing corrosion resistance and oxidation resistance.
The torque wrench spring is one of the core components of a torque wrench, used to provide the wrench's torque. By changing the compression state of the spring, the required torque can be adjusted, thus achieving precise control of the tightening force on bolts or nuts.
A torsion spring (torsion spring) is a helical spring that can withstand torsional deformation. Its ends are fixed to other components. When the components rotate around the center of the spring, the torsion spring generates torque or rotational force, pulling the components back to their initial position. Torsion springs can store and release angular energy, or statically fix a device by rotating a force arm around the central axis of the spring body.
High-precision springs are elastic components with high precision, high performance, and high reliability, widely used in fields with extremely high requirements for precision and stability. Their manufacturing process is complex and requires precise design, material selection, processing, and testing to ensure the spring's size precision, elastic performance, and service life.

Select spring material based on the temperature difference
Spring materials working under high-temperature conditions require good thermal stability, relaxation or creep resistance, oxidation resistance, and resistance to corrosion by certain media. As the operating temperature of the spring increases, the elastic modulus of the spring material decreases, leading to a decrease in stiffness and load-carrying capacity. Therefore, for springs operating under high-temperature conditions, it is necessary to understand the change rate (value) of the elastic modulus and calculate the interference of the reduced spring load-carrying capacity on the performance. According to regulations, when the operating temperature of a helical spring is above 60℃, the shear modulus should be corrected. The formula is: Gt=KtG where G is the elastic modulus at room temperature; Gt is the shear modulus at operating temperature t; Kt is the temperature correction coefficient, selected according to Table 2-98.

Points to note when using Zhuji springs
When using springs from Zhuji, there are some precautions. Each spring has different specifications and must not be replaced. The design and production of these springs adhere to very strict size requirements, and the relevant usage values have been precisely analyzed. Mixing them will affect the spring's performance. Not only should they not be mixed, but they also cannot be arbitrarily modified.
