Flat strip parts can be very complicated in their form. Inside many products such as mobile phones, computers and medical equipment there are a wide variety of shapes all formed from a simple coil or sheet of flat material. Many flat strip parts are designed to perform more than one mechanical function thereby reducing the …
Nesting springs means to have one or more springs fitted inside a larger spring. Nested springs enable the spring designer to get more loadbearing material into a fixed space. By so doing, the springs are able to support a greater load than one spring alone could withstand. By reducing the working stresses within each nested …
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 …
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 …
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 …
Spring materials are chosen for their strength and are amongst the strongest materials used in industry. Springs are designed to work to far greater working stresses than virtually any another component. Also spring materials have to be able to work in extreme environments such as elevated or low temperatures and corrosive situations and be able …
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 …
