The current products include: compression springs, torsion springs, extension springs, auto parts springs, wire forming springs and spring sheets, etc.
Compression spring product features
Compression springs provide resistance to external load pressure. Compression springs are generally wire coiled at equal pitches and have a fixed wire diameter. Compression springs use multiple open coils to provide resistance to external load pressures, such as gravity pressing down on a wheel, or your body against a mattress.
Applications of compression springs
Compression springs are the type used in appliances, motorized equipment, electric motors, and more. Compression springs are compressed by a load acting on them or their ends are compressed by the design of the wire trying to return the spring back to its original shape, thereby pushing the load back. Main application directions: medical respiratory equipment, medical mobile equipment, hand tools, home care equipment, shock absorption, engine valves, etc.
Compression springs are generally wire coiled at equal pitches and have a fixed wire diameter. In addition, there are also conical compression springs, or a combination of conical and linear springs. Depending on the field of application, compression springs can be used to resist pressure and/or store energy. Round wire is the most commonly used compression spring, but there are also compression springs made from square, rectangular and specially shaped wires.
How to choose a compression spring
1. Use limit: The load type of the spring is determined by the life of the mold and the stroke. (Jiusheng Spring)
2. The inner diameter of the spring is larger than the diameter of the mounting pin.
3. The outer diameter d of the spring is 1mm smaller than the mounting hole on one side.
4. Calculation of free length, calculated by stroke preload and compression ratio.
5. The spring specification length is preferred to use specification products.

Advantages of our springs: Springs have a very wide range of applications and are suitable for almost every industry. We have a wealth of raw material storage and can quickly manufacture springs. Our springs have good elasticity, high temperature resistance, environmental protection and no pollution, strong pressure resistance, corrosion resistance, suitable for Wide range and so on.
Our springs offer custom services. Including the size, material and packaging of the compression spring, it can be customized according to customer requirements.
1.The specifications of each spring are different, and the design has been determined, and the compression spring should not be easily replaced with each other when used, nor can it be modified at will. 2.When repairing and maintaining the mold, the old and new springs should not be mixed in different applications, which will cause the spring to receive uneven load, which is the failure of the spring with large load. 3.Repairers often correct the standard spring due to the lack of suitable springs in use, such as truncation, grinding the inner and outer diameters or series springs, which will cause the spring to not adhere to the original characteristics, resulting in premature failure.
