It is made of coiled wire, and its structure is composed of many repeated straight wires and semicircular arcs. It is installed inside of the magazine or charger of a firearm and pushes the bullet through the compression force of a spring. Its force and speed are determined by the diameter, outer diameter, and diameter of the wire. Depending on the number of turns, the end of some magazine springs need to be bent, mainly to facilitate fixing to the pin, because there is a gap between the magazine wall and the magazine springs. This gap will cause the springs to bend slightly. This will cause damage in the future.
The focus of the use of magazine springs are the solid height, so the manufacture of this type of springs is to understand its key requirements. If the magazine springs are used in a real gun, the focus of its manufacture is the size, tolerance and parallelism. The larger the springs, the more difficult it is to manufacture, because the continuous increase in weight during the forming process will increase the difficulty of forming. Another test is after the completion of the tempering process, due to the characteristics of the material itself, the parallelism will change after heating, so this type of springs need time to achieve a stable parallelism.
For most guns, the magazine springs are the typical style, but some types of guns require different lengths, strengths, and numbers of coils. Take rifles and hand guns as examples. Some rifles have longer magazines or chargers than ordinary hand guns, so the magazine springs in the rifle will be longer than the magazine springs of the hand gun, and there may be size differences in design. Depending on how the magazine springs are placed and the required speed and stroke of the magazine, other differences may apply to different guns. We have the most advanced equipment and excellent manufacturing technology, so that we can quickly produce customized magazine springs and achieve strict specification control.
