A compression spring offers resistance to the axial compressive force. It is an open-coil (pitch) helical spring. They are generally coiled as constant diameter cylinder. Compression springs can manufacture of any size, length and dimension. The space allotted will decide the allowable solid height, inner diameter and outer diameter of compression springs. Compression springs offer resistance to linear compressing forces (push), and are in fact one of the most efficient energy storage devices available. Compression Metal Springs are found in a wide variety of applications ranging from automotive engines and large stamping presses to major appliances and lawn mowers to medical devices, cell phones, electronics and sensitive instrumentation devices.
