Extension springs are mainly used in those fields

Extension springs, also called tension springs or helical extension springs, are helical springs that accept axial tension. Most of them are circular in cross-section with equal pitch and are widely used in many fields. The following are several areas where extension springs are mainly used:

Defense and Aerospace: In defense equipment and aerospace vehicles, extension springs are used to provide the necessary tension and support to ensure stable operation and precise control of the equipment.

Shipbuilding and Marine Engineering: Extension springs are used to withstand various tensions in shipbuilding and marine engineering equipment, such as tension balance in hull structure, equipment fixation on offshore platforms, etc.

Computers and Electronics: In the manufacture of computers and electronic equipment, extension springs are used to connect, fix, or provide necessary tension, such as connectors on circuit boards, tension balance inside displays, etc.

Automobiles and Transportation: In automobile manufacturing, extension springs are widely used in suspension systems, seat adjustment, hood support and other aspects to improve driving comfort and vehicle safety.

Molds and Manufacturing: In-mold manufacturing and industrial production, extension springs are used to provide mold opening and closing force, maintain the accurate position of the mold, etc., to ensure product accuracy and production efficiency.
Medicine and biochemistry: In medical equipment and biochemical experiments, stretch springs are used for tension control of precision instruments, sealing of reagent bottles, etc., to ensure the accuracy and safety of the experiment.
Energy and industry: In energy fields such as nuclear power, wind power, thermal power, and industrial fields such as engineering machinery, mining machinery, and construction machinery, stretch springs are used for equipment support, tension balance, and energy storage.
Daily life: Stretch springs are also widely used in various products in daily life, such as lamps, water heaters, electronic scales, sockets and other household appliances, as well as vacuum cleaners, washing machines and other household appliances, to provide the necessary tension and support.
In summary, stretch springs play an indispensable role in modern industrial production and daily life with their unique performance and wide application fields.
