Although metal springs are not the focus of many technical applications, they are nevertheless indispensable design elements. The requirements placed on the springs are varied and individual. Metal springs often have to fulfil several tasks at the same time, which is why standard springs available from stock are often not sufficient and special solutions are required instead.
Classification according to the stress on the spring material

Bending springs | metal springs subject to bending stress
Most Bending springs are leaf springs (rectangular cross-section), wire springs are in the minority. This type of metal spring can be designed as a rod, plate or shell and are mainly subjected to bending.
Torsion springs | torsionally stressed metal springs
Most Torsion springs consist of rods or wire with a round cross-section. They perform a permanent rotary movement during use.
Tension & compression springs | tension & compression metal springs
Extension springs and compression springs are dynamic components. They absorb forces when they are pulled apart/compressed and release them again when they are released.
The requirements for metal springs are diverse. What kind of load is exerted on the springs and how high is this load? In what environment and at what operating temperatures are the springs used? How can the metal springs be designed and dimensioned with regard to the available installation space? Do the springs require additional surface finishing?
Manufactured from metallic materials, springs must be optimally designed in order to fulfil their function as holding or Clamping spring reliably. Thanks to their design, a specific choice of material, the spring material used and final surface treatments, they ensure a secure connection in technical applications. Metal springs can therefore fulfil a wide variety of tasks.
The optimum metal spring
The expertise of a metal spring manufacturer - in all areas of production - determines the efficiency and sustainability of the individual technical metal spring.
