Compression springs are open-coil helical springs that resist an axially applied compression force, usually wound as a cylinder of constant diameter. Vanel Tech offers compression springs in various sizes and shapes to suit various customer applications. Required by various applications, there are different shapes, except helical, of compression springs such as conical, concave, convex or combined, etc. These springs generally contain the highest potential energy when the spring is compressed. When they are not compressed, there is space between each turn. Vanel Tech manufactures compression springs to customer requirements and international standards to suit applications.
Compression springs offer resistance to linear compression forces (thrust) and, in fact, are one of the most efficient energy storage devices available. They are found in a wide variety of applications ranging from automotive engines, medical devices, electronic devices and instrumentation, etc.
