Avoiding fatigue performance in the manufacture of flat strip products

There are many different methods which can be applied to avoid fatigue performance in the function of flat strip products. The fatigue performance can be greatly affected by the edge and surface condition of the material, it’s possible to purchase some strip materials with a dressed or rounded edge which can greatly improve performance. However, if the components are punched out of the material the edge finish will depend upon the performance of the tooling. Flat strip parts can […]

Corrosion protection of springs

In some instances a spring is required to operate in a corrosive environment which means some form of surface protection is needed. The options of protection available will depend on the application of the spring.  If cost is an issue, or where the material needs to be of a required strength, than it may not be possible to design a spring with materials that will not corrode.An obvious choice is the use of nickel alloys, they are excellent for corrosion resistance, however the cost ca […]

What factors should be considered when manufacturing springs to avoid fatigue performance

One of the key factors that a spring user requires is reliability, there has been much research into the behaviour of springs under fluctuating loads to ensure a spring is long-lasting.If a spring will only be operated for less than 10,000 cycles during its lifespan then fatigue does not need to be taken into account. Any spring that will be performing for more than 10,000 cycles can be affected by fatigue and this needs to be factored in during the design process.​The factors that can aff […]
