Spring coiling is a manufacturing process used to create springs from metal wire. The wire is wound around a cylindrical form, which shapes it into coils. This process can produce various types of springs, including compression, extension, and torsion springs, depending on the design and application. The coiling process involves precise control of tension and diameter to ensure the spring functions correctly. After coiling, the springs may undergo heat treatment to enhance their strength and elasticity. This technique is essential in many industries, including automotive, aerospace, and electronics, where reliable spring performance is crucial.
