Spring Life Expectancy

Posted on July 31, 2017

Spring Life ExpectancySprings play an important role in the function of many products and systems. When choosing springs, spring life expectancy is an important consideration. Since springs are used in such a broad range of applications and environments, spring life expectancy can vary and can be difficult to determine.

Some of the variables that influence spring life expectancy include materials used, environmental conditions, and the amount of force involved in the application. The way a spring is designed also affects how long the spring will last. In fact, most cases of premature spring failure occur due to a flaw in the design of the spring.

Spring design flaws that influence life expectancy can involve poor materials and workmanship, but they can also be due to improper design. If a spring was not designed properly for its application, you can expect the spring life to be very short. Stress or force beyond what the design allows can lead to spring breakage or cause the spring to set. For example, an extension spring designed for strength may lack flexibility. If extended too far, it may break in the body or at the ends.

Choosing the right material for the application is also important part of the design. Hard drawn wire is most commonly used for low stress applications, while high stress applications need a stronger choice, such as music wire. If the spring will be exposed to harsh elements, consider using a grade of stainless steel or zinc plating. These options will deter rust and improve the spring’s life expectancy.

One of the most important things to keep in mind about life expectancy is that it is very difficult to determine.  There are so many different factors involved, some of which are unknown, that it’s hard to define. The environment in which the spring operates is probably the biggest unknown. Discussing these environmental factors with our team will help ensure proper design and in turn a longer lasting spring.

In order to achieve optimal spring life expectancy, trust a spring supplier that will assist you in evaluating your process and determining the best design for your job. The spring design specialists at WB Jones are here to assist! Contact us today!

Tension Springs Explained

Posted on June 26, 2017

Tension springs are wound helical coils that are wrapped tightly together to create tension. Also called extension springs, tension springs provide extended force when the spring is pulled apart from its original length. These springs typically have hooks, loops, or end coils at both ends of the body, which attach to other components. When these attached items move apart, the tension spring pulls them back together.

Tension springs oppose extension in the way they are wound. The actual tension of the spring varies depending on the load requirements of the application. Spring tension is determined by the outside diameter and wire diameter of the spring as well as how tightly the spring is coiled.

Tension springs are available in a wide selection of sizes for applications ranging from springs for small medical devices to trampoline springs. Automotive parts and assemblies, garage door components, vise-grips, washing machines, farm machinery, and toys are just a few more examples of end products that commonly include tension springs.

Tension springs end styles vary based on the application for which they are being used. Changing the diameter of the coil, wire thickness, and length of the spring, allows these springs to accommodate a variety of loads and application requirements. Tension springs, like most types of springs, can be made from a broad range of different materials to suit particular application needs. Factors such as temperature, stress, and corrosive elements that come in contact with the springs will have an impact on the material selection.

W.B. Jones specializes in the design and fabrication of high quality tension springs. Our experience and capabilities include the fabrication of custom tension springs made to precise specifications. All of our springs are manufactured in the U.S. and most custom orders ship within 3 to 10 days.

Three Issues That Cause Springs to Fail

Posted on June 26, 2017

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.

  1. 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.

  1. 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.

What is Music Wire?

Posted on May 31, 2017

Music wire is a highly versatile type of wire, however as the name implies, it is best known for only one of its uses. It is made from high carbon steel, making it ideal for high-stress applications such as piano strings. In this particular application, the wire is stretched to an extreme amount of tension and it is continuously struck by hammers to create the piano’s sound. This example provides a great illustration of the strength of music wire.

In addition to its high and consistent tensile strength, music wire is also able to handle severe bends. These characteristics make this type of wire a widely used choice for coiled springs. Another advantage music wire offers is its cost, which is comparable to the lower quality carbon steels, especially when the wire diameter is small and the quantity needed is low.

For all of its advantages, there are some drawbacks to using music wire:

Lack of corrosion resistance – application of a protective coating such as zinc plating is an option however it will just slow the corrosion.

Inability to withstand high temperatures – For high temperatures above 250 degrees F, 302 stainless steel is a better option.

Loss of high tensile strength as the wire diameter increases – In most cases spring designers will recommend oil temper at these large wire diameters.

Not cost effective in low stress and large quantity applications – Hard drawn carbon steel is a better choice for large production needs and low stress applications.

When you need springs, it is best to speak with an experienced spring manufacturer that can help you determine which type of spring and which material will provide you with the best application fit and performance. If you are not sure whether or not music wire springs are the best choice for your application, contact us to speak with one of our spring experts.

Understanding Steel Springs

Posted on April 28, 2017

A wide variety of industries depend on steel springs. Some of these include electronics, medical, military, automotive, oil and gas, telecommunications, textiles, agriculture, and aerospace. Applications for steel springs include power equipment, fitness machines, retractable tape measures, timing devices, gardening equipment, toys, as well as a variety of safety mechanisms.

Steel springs are fabricated from tempered wire. Different wiring drawing processes are used to create distinct wire diameters. Starting as a 100 to 1000 pound bar about 2” in diameter, the wire is continually drawn through smaller dies, reducing it to the required diameter and enhancing the tensile strength of the metal.

The most widely used steel types used in the fabrication of steel springs are carbon steels and stainless steels. Music wire is commonly used due to its high carbon content, and results in better quality and more uniform steel springs. A drawback to the use of music wire and other carbon steels is that they rust.  Stainless steel is a better option for steel springs that will be used in wet environments, due to the corrosion resistance of stainless steel. When creating springs from stainless steel, it is important to keep in mind that some types of stainless are slightly magnetic in spring tempered form.

Understanding Extension Springs

Posted on March 9, 2017

Extension springs are commonly used  in automotive assemblies, garage door mechanisms, hand tools,  toys, trampolines, washing machines, farm equipment, and more. They are available in a wide range of sizes, from tiny extension springs for medical devices to larger sizes for industrial machinery. Extension springs are attached to other components on both ends. As the components move apart, the spring provides a force that brings them together again.

By design, extension springs are engineered to absorb and store energy by offering resistance to a pulling force. When the extension spring is slowly stretched the tension force is resisted because the spring is attempting to return to its coiled resting position. The farther the spring is extended, the greater the degree of resistance it will have.

Extension springs are usually cylindrical in shape and closed wound. End styles vary based on the application for which they are being used. By varying the diameter of the coil, wire thickness, and length of the extension spring, they can be designed to accommodate a variety of loads and application conditions. As with most spring types, extension springs can be fabricated from a number of different materials to suit individual application needs. Temperature, stress, and corrosive environments are examples of factors that will influence material selection.
