What Is Spring

A spring is a device consisting of an elastic but largely rigid material (typically metal) bent or molded into a form (especially a coil) that can return into shape after being compressed or extended.[1] Springs can store energy when compressed. In everyday use, the term most often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel. An example of a non-metallic spring is the bow, made traditionally of flexible yew wood, which when drawn stores energy to propel an arrow.

Types Of Springs And Their Uses

There are several types of springs used in different capacities. Generally, there are three main categories, and each category has its subcategories. Below are the properties of the different spring types and their applications.

Compression Springs

Compression springs are open coiled springs with a constant diameter and space between each coil. The springs are compressible only one way as they resist axial compression. These spring types are widely applicable in product manufacturing, such as valves and suspension.

Extension Springs

Extension springs are closed compression springs. They function by elongating during tension and storing energy. When on tension removal, the mechanical spring returns to its original shape dissipating the energy. Extension springs are an important part of garage doors, pull levers, jaw pliers, and weighing machines.

Torsion Springs

A torsion spring is attached to two components horizontally or vertically using their two ends. They function by storing and releasing rotational energy. The tighter the winding, the more energy the spring stores and releases on load removal. They are applicable in garage doors, watches, etc.

Spiral Springs

Spiral springs are rectangular metal strips made into a flat spiral that can store and release a reasonable amount of energy at a constant rate. Due to the constant release of energy, they are applicable in making mechanical watches, seat recliners, toys, etc.

Functions of Springs

A spring’s main function is to store energy and to release that energy when the force upon it is removed.
Compression Springs
A compression spring’s unique design means that their compressed helix shape allows them to resist compressive forces.
Torsion Springs
The torsion spring is a coiled spring designed to have a rotational or twisting motion that exerts a force.
Extension Springs
The extension spring, also known as a tension spring, has coils that are wound together, designed to give a pull force through an end fitting or loop when extended.

Top Things to Consider When Choosing a Spring

The spring application

It goes without saying that a spring will have to perform a specific task or function. This means that different springs are used for different applications, so selecting the right one is vital. If you need springs for a mattress, for example, it’s highly likely you’ll choose compression springs above other types.

The right spring size

All springs are not created equal, as they come in a vast array of shapes and sizes. Size has a huge influence in choosing the right spring for your project, so it’s crucial that dimensions are accurate and suited for the end goal of the spring. When designing and manufacturing a spring, it’s important to consider both the inner and the outer diameter of the spring, its free length and its solid height. You also want to consider the spring materials, as that will influence the size of your spring as well.

Resistance to extreme temperatures

This is an important feature for springs. Being able to perform when in extreme cold or heat is essential for many industries, from automotive to aerospace. If your springs have to function in a harsh environment, choosing a durable material that will not weaken or break under low or high temperatures is the first step in spring design. Inconel carbon, for instance, is capable of operating optimally in temperatures up to around 870oC.

Resistance to corrosion

The same is true for corrosive environments. Springs are versatile and used in a wide range of industries and applications, with many having to perform in corrosive settings or in water. For this reason, an important consideration in selecting the material for the spring is its resistance to corrosion. Stainless steels are suitable for this, as are high nickel alloys.

Resistance to magnetic forces

Will your spring have to perform in a magnetic environment? If so, you want its material to be non-magnetic, especially if the parts surrounding it are magnetic, so that it doesn’t oscillate when placed in a piece of equipment or instrument.

For instance, you may need a spring made from stainless steel but still require something that is non-magnetic at the same time; however, stainless steel spring wire is made by cold drawing and will be slightly magnetic when in a spring temper condition.

Common mistakes when designing a spring

Design mistakes can be expensive, especially if they’re found across a high-volume order. They can also be time-consuming, since springs would have to be recalled, redesigned and manufactured again. Airedale Springs have many years of experience in the industry, so we know exactly what to avoid when it comes to spring design and how our clients can save time and money.
Some of the most common mistakes we’ve come across include:
Choosing the wrong material – Picking the right material for your spring is a crucial step in the design and manufacturing process, since it needs to account for the factors we mention above (temperature, corrosion, etc). This will ensure the integrity of the spring and allow it to perform well in its environment. Selecting the wrong material will lead to issues such as breakage and poor resistance to wear.
Having the wrong end types– Spring ends are just as important as the springs themselves, since they will impact how well the spring will perform. For example, if you have an extension spring, you want it to be able to hook or hoop to a piece of equipment or machinery, since they start in a compressed state before being pulled apart. Creating the right type of ending, therefore, ensures the spring’s optimal operation.
Not accounting for stress– During its lifetime, a spring will have a certain amount of force applied to it repetitively. In order to prolong its lifespan, the design phase must consider its application and environment, in order to determine the best material to withstand stress. The metal should allow the spring to be malleable but not break or lose its strength over time.

Popular Types of Springs and Their Uses

Compression Springs

This is the most popular type of spring made. It gets its name from the compressive force it carries when loaded. Its mechanical energy is released when an opposing force, i.e., a load, is applied to it. Compression springs get shorter as the load gets heavier. The space between the coils closes until the compressed length has reached its maximum load.
These types of springs are found in many manufacturing applications—industrial equipment, pens and notebooks, precision instruments and tools, drilling equipment, mining equipment, electronics, automotive parts—that require variable and opposing force between components. End designs vary—they can be open or closed, where the last coil is squared or flattened against the adjacent coil via grinding the surface. Popular configurations of compression springs include the hourglass (conical), barrel (convex), and conical shapes.

Extension Springs

The extension spring, also referred to as the tension spring, releases its mechanical energy when a tension load is applied to it—the spring resists stretching when pulled. As the opposite of compression springs, extension spring coils touch at a rested position and become longer when force is applied. They feature a variety of hooks, loops and coil designs at either end. No matter the end configuration, the specific design is intended to attach two components to each other. Due to their inherent tensile strength, extension springs absorb and store energy, as well as create resistance to a pulling force. The components are found in carburetors, garage or commercial doors, trampolines, washing machines, farm machinery, and much more.

Torsion Springs

As the name suggests, torsion spring’s mechanical energy is derived through torque or rotary force. In other words, torsion springs must be wound; the end of the spring is rotated through an angle when a load is applied. As it is wound up, the diameter of the spring is reduced and its body lengthens. When released, it exerts a twist-like action that can close a screen door, clamp a clothespin, or snap a mousetrap. Torsion-bar suspensions are commonly used in many vehicle suspension systems—cars, trucks, and military vehicles. Custom design features single-bodied and double-bodied torsion springs with such end configurations as straight, offset or hinge—to meet the design requirement of the component.

Factors to Consider When Choosing a Spring Supplier

Cost – price vs value
Cost is undoubtedly the first factor many businesses consider when comparing spring suppliers, as the price of a spring will directly impact your bottom line. That said, it is important to differentiate between price and value and understand that just because one spring supplier is cheaper than another, this does not mean you will necessarily be getting better value for money.

The price of spring is easily calculated. When you make an enquiry with a supplier, they will give you a quote based on your requirements and the volume of your order. Of course, prices between suppliers will vary, and your decision will likely be guided by how much you are willing to pay. But before you opt for the cheapest supplier, consider the actual overall value, not only of the spring but of the supplier’s service and how other factors impact the total cost of the product.

Value is harder to define than price, so let’s look in more detail at what we mean when we talk about value.

Product quality
Let’s say you are looking for a small spring manufacturer; is it worth paying more for a better quality spring made from higher quality materials that will last longer than the cheapest available option? Cost and quality often go hand in hand, and it is no secret that you should expect to pay more for a better quality spring. That said, you want to pick a spring supplier who will deliver the quality they promised consistently and meet your expectations with every order.

Lead times
The latency between the beginning and completion of the spring manufacturing process should align with your expectations and demands. If a supplier is offering heavily discounted springs that beat all the competitor’s prices, but the lead time between spring design and delivery surpasses your own deadlines and means you won’t be able to complete projects on time, then the partnership will not work.

You should strive to find a spring supplier who is honest and realistic about their lead times, as failure to complete a project on time and supply your springs when you expect them could have seriously detrimental knock-on effects for your business. Many spring suppliers, ourselves at Springs included, use automation to boost efficiency and provide customers with more accurate, realistic lead times.

How long your orders take to fulfil will depend heavily on how many springs you’re ordering, whether they’re stock or custom, how readily available the materials required are, and how busy the supplier is. When making your initial enquiries to spring manufacturers, ask about lead times, whether they have the flexibility and capacity to do short, medium and high volume runs, and get the supplier’s opinion of possible delays due to supply chain disruption and material shortages.

Location
Deciding whether to opt for a local supplier or expand your search further afield, maybe even overseas, will depend mainly on your own business values and the direction in which you see the company growing.

Let’s say you’re a British company that prides itself on sourcing materials from local businesses, with interest in rising to the challenge of greener manufacturing and keeping your carbon footprint to a minimum. You will likely find a UK based spring supplier a better fit than trying to outsource the business to a foreign company. Using a British manufacturer will reduce transportation costs, carbon emissions and align with your company’s values.

On the other hand, if you are a growing business looking to expand into new countries, choosing an international supplier based closer to your overseas facilities or headquarters may be more beneficial. Lead times will likely be reduced, as will the financial and environmental costs of shipping, and the supplier will be fully aware of their country’s rules, regulations and laws.

Reputation experience and shared values
Choosing a manufacturer who shares your company values, has a solid and reliable reputation, and is an expert in their field is pivotal to forming a healthy working relationship with your spring supplier. Do not hesitate to ask potential suppliers questions that will help you determine whether they’re a good fit for your business’s needs. For example, do they have experience making springs for your industry? Do they have a thorough knowledge of spring materials and understand the conditions and environments under which the springs you require will need to perform under? Do they seem open to working with you and listening to your requirements to ensure the spring meets your exact specifications? Do they have testimonials from existing clients that show what working with the supplier is really like?

These are all valid questions and ones that any reputable spring supplier will be happy to answer and provide evidence to support their claims. However, it is also essential to choose the spring supplier who shares your company values. For example, If sustainability is a crucial focus for your business, choose a spring supplier that uses 100% recyclable metal across its products and can demonstrate how they are actively finding ways to reduce energy consumption in their manufacturing processes.

FAQ

Q: What is a compression spring?

A: Compression Springs are open-coil helical springs wound or constructed to oppose compression along the axis of wind. Helical Compression is the most common metal spring configuration. These coil springs can work independently, though often assembled over a guide rod or fitted inside a hole.

Q: What is the difference between a pressure spring and a compression spring?

A: Although a tension and compression spring are both helical coiled springs, the difference in their functionality and purpose can be significant. In essence, tension springs are designed to bring components together, whilst compression springs are made to keep components apart.

Q: What is the difference between a gas spring and a compression spring?

A: The main difference between the two springs – apart from how they work – is that gas springs can exert a much greater force than traditional compression springs, due to the nature of the compressed gas and the amount of pressure it can apply.

Q: What does it mean when a spring is compressed?

A: When a spring is compressed or stretched, it will try to restore its equilibrium position by exerting a force equal and opposite to the external force. So the external work done by us in compression as well as stretching will store in the spring as potential energy (in terms of restoring force).

Q: What is another name for a compression spring?

A: They are commonly referred to as coil springs and in some instances also known as helical coil springs. Some of the most popular names are: Basic compression spring, Coil spring, Helical coil spring, compress springs, push springs, etc.

Q: Will a compressed spring lose its strength?

A: A spring under tension for an extended period of time can become weaker. ... Springs are specifically designed to deform in order to absorb energy from outside stress, then return to their natural state when they release that energy.

Q: What is the alternative to a compression spring?

A: Wave springs are commonly used in limited-space applications, such as medical devices, electronics, and automotive components. The advantages of wave springs as an alternative to compression springs include: They offer a compact design, allowing for efficient use of space in applications with limited axial space.

Q: Does stretching a compression spring make it stronger?

A: Stretching a spring within its elastic limit can enhance its strength in terms of increased spring constant and energy storage capacity. However, it is crucial to exercise caution and avoid stretching beyond the elastic limit to prevent permanent deformation or failure.

Q: What happens when you release a compressed spring?

A: Compression springs store and release energy when subjected to a compressive force. As the spring compresses, it stores energy within its structure. When the force is removed, energy is released and the spring expands to its original length.

Q: What causes a compression spring to break?

A: Overloading and exceeding the working load limit (WLL) can cause compression springs to weaken and eventually break, posing significant safety hazards. Other factors that can affect product reliability and increase the likelihood of failure include: Fatigue failure due to repeated stress cycles.

Q: What is an example of a compressed spring?

A: Compression springs work to resist force and store energy in many different kinds of products and equipment. Examples of compression spring application include door locks, compressors, switches, mattresses, watches, ball point pens, and electronic devices.

Q: How do you weaken a compression spring?

A: Cutting to the Chase: A straightforward method to reduce spring tension is to shorten the length of the spring. By careful measuring and removing the end coils with a pair of bolt cutters, you can effectively decrease the stiffness. Heat: The Softener: Gently applying heat to a spring can increase its pliability.

Q: Are compression or extension springs better?

A: In general, extension springs are more suitable for applications that need to lift heavy loads. They work well for things like garage doors and drawers. Compression springs are more suitable for applications that need to resist twisting or torsion.

Q: How much can you compress a compression spring?

A: Some compression spring designs can be pressed down all the way to solid height. When a spring has just the right dimensions and elasticity, it can safely be compressed all the way. Other designs may be so stiff or sturdy that if you try to do this, they will break.

Q: What are the characteristics of a compression spring?

A: There are four basic types of compression spring ends, as shown. The type of ends specified affect the pitch, solid height, number of active and total coils, free length, and seating characteristics of the spring. The most common end types are closed but different ends are appropriate for different applications.

Q: Do springs twist when compressed?

A: Its design features and material properties determine a spring's behavior under compression. Compression springs do not twist when compressed because their axis is straight; however, if you apply an off-center load to a compression spring during compression, some twisting may occur due to unequal forces between coils.

Q: What can I use instead of springs?

A: Alternative Springs
Torsion Bars. Torsion bar springs work in an almost identical way to anti-roll bars. ...
Rubber. Rubber has been tried and tested within motorsport a few times as a spring. ...
AIR. Air is still a successfully used spring within the automotive industry today.

Q: What is the strongest spring?

A: With these characteristics, Titanium springs are one of the strongest and most weight-sensitive springs available. Not only are titanium springs exceptionally strong, they are also corrosion resistant. Titanium springs are used in many industries and in many applications, from motor bikes and race cars to aircrafts.

Q: Can you reset a stretched spring?

A: Many springs will not come back to the original height after being compressed, but Mid-West Spring and Stamping can pre-set your springs, if needed.

Q: What happens when you stretch a spring too much?

A: If extreme force is exerted, one can stretch the spring, exceeding a specified point that its deformation will happen. The spring will revert to a forever distorted shape on the release of the stress, which will be altered from its original shape.

Q: Can a compression spring be used as an extension spring?

A: Extension springs and compression springs aren't the same. Extension springs are intended for use when two components try and pull away from each other. In comparison, compression springs are intended for use when two components try and push towards each other.
