Compression springs are wound or constructed to oppose spring compression along the axis of wind

Spring winding services fabricate springs according to customer specifications. They use winding machines or winders to pull a wire and coil it into a spring shape. Spring winding services also use grinders and wheels, finishing equipment such as ovens and passivating tanks, hand tools, testing equipment, and tooling stock

Die springs are helical compression springs that are made from rectangular wire. For the same deflection, they can carry roughly 30% more load than compression springs that use round wire

Wave washers or wave springs are wavy metal washers designed to provide a compensating spring force and sustain a load or absorb shock

Specialty or proprietary products and accessories related to springs

Metal ring seals are static devices that can withstand high operating temperatures, pressures, and vacuums. They can also withstand cryogenic conditions and high face-to-face cycling.

Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line.

Carbon steels and alloy steels are ferrous alloys that contain carbon and other alloying elements such as manganese, chromium, molybdenum, and nickel

Stainless steel alloys are austenitic, ferritic, martensitic, precipitation hardened (PH), and duplex metal materials that are available in a wide variety of grades, shapes, and sizes

Gas springs provide controlled motion and speed for elements, such as lids and doors, that open and close

Extension springs are designed to oppose spring extension and/or provide return force to devices with extended positions

Constant force springs are tightly coiled wound bands of pre-hardened spring steel or stainless steel strip. When extended, a constant force is exerted and maintained as the spring is allowed to close

Torsion springs are designed and wound to be activated rotationally, and to provide an angular return force

Ferrous metals and alloys are based on iron and include carbon steels, alloy steels, stainless steels, cast iron, cast steel, maraging steel, and specialty or proprietary iron-based alloys. 

Preload springs, spacers and washers are used to provide end-play take up or a constant preload for bearings, gears and other mechanical components and assemblies
