After springs have been punched or bent, they can undergo a finishing treatment, in order to adjust the mechanical properties.
The purpose of a surface treatment has several reasons, to clean, visually adjust gloss, matte, conductivity, reduce or increase resistance, improve service life, improve corrosion resistance.

Wire springs are available in various wire types and wire thicknesses. From 0.08 mm to extremely thick thermoformed springs. Many manufacturers have their own specialty, this has to do with the series size, the thickness of the material, the type of material. There are many different types of wire springs, we can distinguish between: extension springs, torsion springs, push springs, wire springs and die springs. Feathers can be supplied with different types of eyes and finishes.
The most common material is spring steel, galvanized spring steel and stainless steel spring steel. In addition, springs made of exotic materials such as Inconel are also available for special applications.
In addition to wire springs, there are also leaf springs. There are very few standard springs available with leaf springs. Leaf springs and cup springs are made according to drawing. Leaf springs are also mainly made of spring steel and stainless steel spring steel.
