Spiral springs are technical, metallic components that are used to achieve a certain degree of flexible movement. In practical use, they can be sufficiently deformed by tension and compression for this purpose. Elasticity is an essential quality feature.
Practical applications are:
Spiral springs are used to store potential energy. Because of their enormous restoring force, they are used in moving-coil movements, spring scales or torque wrenches. They are used as a non-positive connection for door stops and friction clutches. A further function is the use as an evasive part when other components change their shape. Due to the ability to redistribute loads, coil springs are also used for spring mattresses. Springs for shock absorbers are used as oscillating spring-mass systems.
Leg springs are tortuous wire springs whose ends project (legs). These are intended to initiate the torque that bends the wire. Typical applications are the mousetrap and the clothespin. Wave springs are made of corrugated flat wire and look like rings. If the installation space is low, these springs are ideally suited (bayonet lock). Torsion springs are made from a single piece of wire with a round cross-section and rods. The tension in the inner edge fibres is higher than on the outside. The materials range from steel, copper alloys, fibre-reinforced plastic to rubber. In addition, there are custom-made products according to customer requirements, such as gas springs.
Requirements for coil spring manufacturers:
Wear resistance, abrasion resistance, flexibility and fast delivery times are indispensable in this industry, as the precision springs have to withstand extreme long-term stress. Reliable customer service and professional assembly are required. The springs must be replaced quickly. The machines and units must not stand still for too long. Customer-specific production is also required in this area. Pressure and tension as well as energy storage are essential topics here.
