Flat Strip Springs – Types of Tooling

There are a number of ways flat strip components can be produced, generally depending on the volume required. When a small number of components are required e.g. prototype samples, it is possible to produce most parts without tooling. Wire-eroding can produce development blanks where required, and standard tools can be used to form the parts …

Corrosion Protection of Springs

Where a spring operates in a corrosive environment some form of surface protection is required. Depending on the application, this can take a number of forms. Obviously, the spring can be designed in a material that will not readily corrode in the application’s working environment, but this may not be possible where costs need to …

Materials for Flat Strip Springs

As with wire, there is a wide range of strip materials available to the spring manufacturer. As many parts produced in strip are not primarily used as a spring, many low strength alloys are used, generally for their formability and electrical conductivity. Strip materials can be obtained in different grades of hardness, and some spring …

Factors affecting the Fatigue Performance of Helically Wound Springs

Reliability is of great importance to many spring users. Without the spring many applications will either cease to work or work less efficiently. Therefore much study has been made of the behaviour of springs under fluctuating loads. If a spring is operated less than 10,000 cycles during its operating life then it is deemed to …
