Compression Springs are open-coiled
helical springs that work by resisting
compressive force.
These springs are manufactured in
cylindrical, conical, concave (hourglass),
convex (barrel) or any shape to suit your
application and are typically made with
round wire.
Closed ends are preferable because they
allow a greater degree of squareness
and prevent tangling. Grinding the ends
permits greater squareness control and
inhibits buckling.
