A compression
spring is an open coil helical spring
offering resistance when a load is applied
against it. This load causes the coil
to collapse at a specified rate of pounds
per inch. Most compression springs are
single diameter, special forms such as
conical, concave (barrel), and convex
(hourglass) are possible but may require
additional set-up time. Round wire is
the ideal choice and is available in various
diameters and types. Round wire springs
can be produced with standard tooling,
thus reducing cost.
Tolerances on compression springs vary
with each design. Defining your needs

An extension
spring is usually a closed coil helical
spring containing energy to resist a pulling
force. The pulling force causes the coils
to separate at a given rate. Included in
the rate is the variable-initial tension.
Initial tension is the load necessary to
overcome the internal forces which holds
the coils tightly together. The amount of
initial tension can be varied and should
be determined prior to spring production.
Tolerances for
extension springs vary with each design.
Free length, (usually measured from inside
hook to inside hook), outside diameter,
end alignment of hooks, initial tension
loads, and rates. Prioritizing your needs
