A rectangular compression spring is an open coil spring that resists axially applied compression. Compression springs are the most common metal spring configuration and are actually one of the most efficient energy storage devices available. In addition to the common cylindrical shape, many shapes are available, including cones, barrels, and hourglasses. Typically, these coil springs are either placed on a rod or mounted in a hole. When you put a load on a compression coil spring to make it shorter, it pushes the load back and tries to regain its original length.

To customize a rectangular compression spring, you need to provide the following necessary parameter information:

Wire diameter d: mm(Description: the diameter of the spring wire, the rectangle is length x width)
Outer diameter D2: mm(Description: the diameter of the outer circle of the spring)
Length L0: mm(Note: the free height of the spring)
Number of laps Na: lap(Note: the total number of turns of the spring)
To customize a rectangular compression spring , you also need to provide the following technical requirements:
turn around:(Description: Left/Right)
Material requirements:(Such as: stainless steel wire SUS, carbon steel wire SWC, piano wire SWP, copper wire…etc.)
Surface treatment:(Description: blackening \ galvanizing \ nickel plating \ chrome plating \ baking paint \ powder spraying \ electrophoresis \ shot peening \ Dacromet \ electropolishing…etc.)
Terminal form:(Description: and tighten \ smooth \ and tighten and smooth)
Strength requirements:(Description: elastic properties, other technical requirements, etc.)
