Compression spring is an important elastic element, mainly used to resist external pressure. They are usually made of wire coiled at equal pitch, have a certain wire diameter, and can be cylindrical, conical, or a combination of straight and conical shapes. In practical applications, compression springs can be used in various fields, including automotive, aerospace, furniture, industrial machinery, etc., to withstand gravity, human pressure or other types of loads.

When considering the use of compression springs, it is important to choose the right type according to the specific application needs, such as compression springs, tension springs or torsion springs. In some cases, such as in commodity futures markets such as soda ash, non-trading factors may suppress the market, but if this suppression is not sustained, it may be like a compressed spring, which shows a strong rebound after the pressure is relieved.
