Spring: Suitable for high and low temperature, corrosion resistance and other office environment, the key raw materials include stainless steel plate spring wire, alloy steel wire, oil heat treatment quenched aluminum alloy spring wire, high and low temperature aluminum alloy spring wire, etc.

Spring characteristics: The spring is a compression spring bearing radial tension. The hook has side hook spring, long hook spring, French hook spring, German hook spring, semicircular hook spring, duck mouth valve hook spring. The "hook" is used to ensure that the tension of the spring comes from, generally made of circular cross section raw materials spring steel, when there is no load, The ring of the spring and the middle of the ring are generally all and tight without a gap. In the resilience (tension) work after the use of the pull, it is used to control the fitness exercise of the parts, storage of kinetic energy, accurate measurement of the size of the force, etc., most of the stretching spring is generally under a certain level of tension, even in the absence of all the load. This primitive tension determines how closely the stretch spring is wound without all the load.
