Three Issues That Cause Springs to Fail

When your product or assembly depends on a spring, spring failure is simply not an option. End product quality suffers and as a result so does the profitability of your business. The best way to prevent spring failure is to understand what causes spring failure in the first place. This post examines three issues that can cause spring failure.

1. Spring Stress

In most spring failure situations, the cause is stress or force that exceeds what the spring is designed to handle. Failure due to spring stress is typically the result of a flawed design, which creates a condition of overstress. The application of too much stress, or more force than is allowed for by the design can cause the spring to break or take set.  For instance, an extension spring that is designed for strength will have very little elasticity. If extended too far, it becomes extremely stressed and susceptible to breakage. This damage can occur at the spring body or at the spring ends. In the event of spring failure due to spring stress, adjustments can be made to prevent future issues.

2. Wrong Material Choice

Understanding the application for which the spring will be used is essential in the selection of its fabrication material. There are many spring wire material options to choose from; the choice will depend on characteristics the spring function will require. For example, music wire is a good option for springs that will require high strength. Gaining an understanding wire types will be very helpful in choosing a material that will reduce the chances of spring failure.

3. Poor Finish or Incorrect Finish Selection

Springs can fail if they are subjected to harsh or caustic conditions. While spring material choice is a factor, the type of finish the spring has is also important. Depending upon the application requirements, springs can be left plain or finished using: zinc plate, black oxide, passivate, or some other type of coating. An experience spring manufacturer will discuss these options with you and guide you in the selection of the best choice for your application.

Spring failure can be avoiding by selecting a knowledgeable spring supplier who will listen to your application requirements and help you select a spring design that is suited for the job. Factors that should be considered include the required extended length to the required load to the actual measurements of an existing spring. The more specific details are factored into the design phase, the less likely it is that spring failure will occur.
