Compression Springs, also known as
coil springs, are open-coiled steel wire
in a variety of cross sections and forms
for linear applications. As compression
springs are compressed, they provide a
force (push) to return the spring back
to its normal height. The force
produced by compression springs
makes them an excellent component
for storing energy, ideal for various
applications. They are used in everyday
items, such as pens, vehicles, and
mobile phones. Compression springs
can be manufactured in any size, with
varying degrees of stiffness, known as
spring rate.
