European Springs Web Team, Author at European Springs Ireland

At European Springs, we are proud of our role in manufacturing high-quality springs and pressings for a broad range of applications. We strive to develop new innovative processes and methods to maintain our status as one of the UK’s top manufacturers. Part of our work is to understand the causes of spring failure and prevent any such losses from occurring in our products with superior techniques.

Spring Design Considerations

With so many applications that require some spring to function, spring failure at any time will be at best a hindrance and, at worst disastrous. As spring manufacturers in Ireland, we understand that spring failure is not an option. However, we believe that by understanding why a spring fails, you can work toward avoiding it for yourself.

Spring Stress is a primary cause of spring failure. Overstessing your spring by applying stress or force that exceeds its specifications indicates a breakdown in the design process. For example, an extension spring will not have much elasticity if designed for strength, so by overextending this spring, you will put it under extreme stress, and it will most likely break.

Wrong Material Choice is also a common cause of spring failure. With so many materials available for your spring manufacture, you need to be sure that you select the best material for the function it needs to perform adequately. For example, Stainless steel is a good choice for clock springs but may not be for other spring types such as valve springs.

Shock loading and other misuses of your spring will lead to spring failure. Shock loading is when the weight of the load increases suddenly or speeds up. Dropping your spring from a significant height is an example of accidental shock loading. The more times the spring is shock loaded, the higher the risk of failure. You can mitigate this with friction devices such as vibration dampening devices or internal damper coils.

The key to our spring manufacturing process is to source specific high-quality materials to meet even the most exacting of production standards. Combined with our in-house contemporary CAD and CAM software and systems, we can help realise a comprehensive range of prototype ideas so you can be sure your specification will work in your required application.

Preserving Your Springs

Even with the best materials, manufacture and design, no spring will last forever; fortunately, as experienced gas spring manufacturers, we know of ways you can increase your spring’s life and prolong replacing it for as long as possible.

Several factors can shorten your spring’s lifetime, but you can ensure your product lasts longer than you expect with careful planning and a reputable manufacturer.

Friction – A spring touching the sides of a shaft (for example, a compression spring inside a gas spring), with repeated friction, will cause increasing damage to both components until one fails.

Environment – A spring that doesn’t have the correct finish will be less likely to function. It will continue to degrade until it fails. In addition, heat or extreme humidity will negatively affect an untreated spring and potentially cause spring relaxation. By keeping these springs cool, you can prolong the life of your spring and reduce the chance of spring relaxation

Stress – This is linked to the overstressing mentioned above. Applying too much pressure to your spring is unlikely to compress as far as it is designed. This will lead to overstressing and breaks. We recommend choosing a larger wire diameter to reduce the chance of spring stress. Additionally, lowering the final load and allowing more room for the spring will enhance longevity.

Prestressing to Prevent Spring Failure

Prestressing is the process where the spring is loaded to the point where the wire is under controlled stress. A spring designed to be prestressed will benefit from withstanding higher pressures and increasing its load-carrying ability while lighter than its equivalents. When spring is prestressed, the changes will increase its lifetime and provide you with a better product.

Shot Peening Improving Operating Life

Shot peening is a method where the surface of the spring is hit with small spheres. It is used on clutch springs, coil springs and compression springs. These impacts will create small indentations, which will overlap as they are repeatedly struck. As a result, the whole exterior of your spring will have a layer of metal in a state of increased residual compressive density. Shot peening essentially increases the tensile strength of your material and makes it far harder for fatigue cracks to start to form. Shot peening is beneficial for:

Preventing corrosion
Cracks and fatigue
Hydrogen embrittlement

Sustainable manufacturing is an important goal for the manufacturing industry, with significant strides already being made. The nickname the ‘green industrial revolution’ has become commonplace as an increasing number of environmentally friendly changes are implemented across the manufacturing industry.

The Goal of Sustainability

Sustainable manufacturing aims to improve current manufacturing processes and create a far more ecologically friendly system without sacrificing productivity. This increased sustainability is not focused on just the manufacturing processes themselves. These positive changes involve the entire supply chain process around the actual manufacturing, both upstream in sourcing new materials and downstream regarding the finished products and waste management.

The environmental element of improving sustainability is related to:

Less resource consumption
Less waste
Lower emissions

By achieving these goals, the industry’s effect on the environment is immensely lowered. True sustainability is about balance. In context, balancing the industrial sector means companies considering the impact of their current working methods throughout the entire supply chain process. by monitoring this impact in relation to the environment, it becomes easy to find those processes that can be improved and eventually significantly improve all your companies impact as a whole.

Support for Irish Manufacturing

The United Nations Environment Program’s International Resource Panel assessed that if there were no change in the way industry worked, greenhouse gasses would build to 43% by 2060. This and other reports inspired significant changes in the industry worldwide, including the UK’s implementation of a NetZero 2050 strategy and the recent hosting of COP26.

The NetZero 2050 strategy is the UK government’s plan to decarbonise all sectors (industrial, commercial and domestic) nationwide and create a nation that is producing no excess emissions by the year 2050. It involves a road map of smaller targets that must be met to accomplish this goal.

As a metal pressing manufacturer, the COP26 conference held at the Scottish event campus in Glasgow was an event we were very interested in. This latest meeting of representatives from the United Nations was of particular importance to manufacturers as they planned to address areas of combating climate change that was lacking. The results were to increase the demand for companies to embrace decarbonisation as a more sustainable method and embrace limiting waste and renewable energy sources.

Ireland once stood at 46^th on the CCPI (climate change performance index), with a high rating in the implementation of renewable energies and a medium-low rating in energy usage. In addition, manufacturing contributes approximately 10% of the total national emissions in Ireland, creating a significant opportunity for companies to find innovations that will significantly improve their environmental impact. A new climate change act was passed in 2021 to serve as a framework to cut emissions across industries by 51% by the next deadline for the NetZero 2050 strategy, in this case, in 2030. The Climate Action Plan inspired a surge in green innovation predicted to support significant changes in the nation’s industries. This plan aims to contribute to the world’s effort to limit the temperature rise to 1.5 degrees and maintain the environment in other ways.

An R&D tax credit is available for manufacturing companies in Ireland. This incentive for research and development enables Irish manufacturers to explore more sustainable operating methods and alternative energy sources, such as investing in solar panels or carbon offset schemes. This tax credit provides 25% on qualifying R&D expenses in science and technology.

Circular Models Are the Future

Many different elements make a sustainable manufacturing company. They include the acquisition of the required materials, the source of the energy to run your facility and what you do with the waste materials afterwards. All these elements can be improved upon to create a truly sustainable process.

All these disparate elements can be collected under the term ‘circular economy. This is the name of a business model for production and consumption that plans to re-evaluate previous linear processes. The essential concept is similar to recycling. For example, spring manufacturers would employ a system of reuse for unused materials to prevent them from becoming waste.

Positive Effect of Sustainable Manufacturing

One element that everyone in the manufacturing industry can agree on is that we have a responsibility to future generations. This is the most significant reason why increasing sustainability is essential, and decreasing the industry’s environmental impact will help ensure that. There isn’t just one primary way to achieve sustainability; many smaller steps can be taken that will combine to have an immense impact.

More sustainable industries will also ensure that habitats remain liveable. In addition, maintaining a high standard for air and water quality and preventing toxins from entering the water table helps the environment and humans. Landfills are one the most significant contributors of harmful toxins to the environment. By recycling as much of our waste as possible, landfills become less necessary. It’s easy to forget that any problem that affects the environment will inevitably become a problem for humans if left unchecked. By protecting the planet, we are also protecting ourselves and the future generations to come.

Sustainable Manufacturing Is the Future

At European Springs, we are constantly working towards discovering new ways to improve our working process for efficiency and environmental impact. As experienced manufacturers of gas springs in Ireland, we have a great deal of experience adapting our work to be the most sustainable it can be.

The gender gap is an issue many male-dominated industries are looking to close. It became such an issue that in 2018, any business or company with over 250 employees must report gender pay gaps, which still applies to date. This enforcement of reporting inconsistencies encourages companies to address their equality in paying wages.

However, the gender gap goes beyond the wages, with the manufacturing industry having significant gaps in the number of employees representing the female gender. At European Springs, we strongly believe in the positive impact closing the gender gap can have on the road to where equality remains as nothing more than the box you tick for data collection.

The Importance of Women in STEM

Studies have shown that since 2010, there has been a 16% rise in women in STEM studies and careers. This rise took the original 562,000 women to an impressive 963,000 in 2021. Whilst this increase is welcomed by the STEM industries. However, it is a long way off from closing the gender gap.

When there are amble labour and skill shortages, closing the gap is not only to increase the awareness of equality in the workplace, especially one so heavily male-dominated, but also to assist the UK in achieving a complete workforce. Furthermore, by supporting and actively participating in female recruitment, STEM industries could help relieve the pressure off overworked staff and increase productivity and morale within the workplace.

Women are vital, especially within the manufacturing process. Many developments, apps, products and much more are not considerate of the female gender due to the significant lack of women in the manufacturing process. Take Apple, for example. On the release of its health app in 2015, it neglected to equate women’s health requirements. This fault was due to the gap in female leads on the project. Without such, it meant the app was centred around the male physique.

Another example of such is butchering. All the standard equipment that most commercial butchering facilities provide for safety doesn’t equate to the natural size of women compared to men and leaves them with unsuitable health and safety wear which could cause significant issues. With more women in the planning, designing and manufacturing positions, the more these errors would be eradicated.

Opportunities Available for Women

Considering women equate to approximately 48% of the labour market, there is still much work to do to close the gender gap within manufacturing. For example, only 8% of women take up apprenticeships in manufacturing, and only 11% of women are currently in executive director roles.

Whilst there is no official exclusion of women, and they are always welcome to apply for any role within the STEM industries, there is still more which could be done. Positive discrimination and more flexible skill requirements, such as soft skills over hard skills, would help to bridge the gap for women.

Soft skills have historically been associated with women but can offer just as much value to a project as hard skills such as IT literacy. Soft skills such as leadership abilities, organisation and quick learning can offer a company much more valuable assets than industry-specific experience.

However, there are many opportunities that women can take advantage of to help them kickstart their careers in the STEM industries. For example, Brunel University in London offers a very successful program for graduates called Women in Engineering and Computing. Since its rollout, they have assisted over 600 new employees in finding positions within STEM industries. Although they are not as widespread as we would like to see as a spring manufacturer, it is the start of aiming for an all-inclusive sector.

Another fantastic opportunity for women is the Meri Williams Scholarship for the University of Bath. This scholarship is offered to all women or non-binary students who wish to work within the STEM sector and will cover £9,000 for the course. Assistance like this goes a long way to encourage more of these students to follow fulfilling careers and have opportunities to change the world, which many other industries don’t offer.

Supporting Women In STEM Careers

As an experienced pressing company that strives for an equal industry, we offer a fully comprehensive engineering apprenticeship program open to all genders and skill levels. We take on apprenticeships year-round, with most of our apprentices being provided with the opportunity for a full-time career in their area of expertise. We also support development through in-job training, allowing staff to progress in their careers without needing to look for a new position elsewhere.

The STEM industry has significantly upped its self-awareness of the gender gap. With many organisations set up to support women and non-binary into stem careers, including the likes of STEM Women, which showcases all the jobs available, working alongside universities, employers and students to find the suitable match for all.

If you would be interested in a career with us, learning about our processes as spring suppliers, you can enquire online using our contact form. One of our helpful team members will get back to you with more information about all our courses and opportunities accessible for women wishing to begin their STEM careers.

Throughout our decades of experience manufacturing high-quality pressings and stampings, we have developed our processes to create an expert service that is constantly in high demand from our clients worldwide.

Our team of engineers have earned a wealth of knowledge in this field, covering manual, semi and fully automatic production to suit the requirements of the customer’s needs. One thing that became evident very early on is that no one type of press applies to every product. An important lesson is that adaptability is vital when conducting the bespoke pressings and stampings operations we offer. Therefore, our engineers must have a working knowledge of various press machines.

How Do Machine Presses Work?

Initially, pressings had to be created by hand. Before the machine press was invented, workers used tools such as hammers to change the shape of the metal. This was not only an agonisingly slow and physically draining process, but it would also be less effective on harder metals. So, this was replaced with the steam hammer around the mid-1800s. The steam hammer (or drop hammer) is the earliest known machine that led to modern pressings.

In modern manufacturing, the machines have replaced their steam with hydraulics. Every device will have its own unique designs, but all pressing machines share specific processes and features. Most pressing machines operate in a straightforward manner by pressing the workpiece plate or die onto the workpiece materials or into it for a more dramatic result. This process is controlled through multiple tool setters that ensure the position of the workpiece. This is when the hydraulics come in; the press pushes the plate or the die against each other using hydraulic pressure. This enables the desired change.

Machine presses rely on high pressure to create the intended results. Most machine presses use around 1 to 30 tons of pressure, which enables them to reshape a broad range of materials such as steel, beryllium copper, and stainless steel alloy. As experienced spring manufacturers, we have used carbon spring steel in our pressing operations with impressive results.

Punch Press

A punch press is the most well-known design of a press machine, and as the name suggests, this press deforms the material by punching holes into it. First, a portal frame with a centred ram or a C frame with a hydraulic ram. Punch presses can be operated manually, but with advances in CNC machining, computer-run punch presses are significantly more popular as they vastly increase production quotas.

Stamping Press

A stamping press is another well-known press design we use at European Springs a lot. While these are similar to punch presses, there are significant differences. They both use a pressurised tool to change the materials workpiece, but stamping does not create clear, clean holes like a punch press.

In this case, the material is pressed into the die to take the same shape, and the material is secured with a bolster plate between the die and a press tool. The tool in the stamping press is pushed into the material, forcing it to deform into the shape of the underlying die.

Lid Press

A Lid press is quite different to the previous examples. Whereas the previous focus was on changing the form of the material, this press is designed to apply a cover to an existing object. As a result, you’ll find lid press machines most used mainly for sealing storage containers such as buckets or cans.

Press Brake

A press brake is exclusively used for metal manufacturing. The role of this press is to bend and deform metal workpieces such as sheet metals. These are sandwiched by a tool and die, similar to other operations, especially stamping presses, with the exception that this machine only works with metal pressings.

Screw Press

As the name suggests, the defining feature of a screw press is the screw-driven ram installed. This updated design has been around for centuries but is now usually controlled through CNC machining to twist and turn the ram and force the tool down onto the workpiece to get the desired shape.

European Springs Pressings and Stampings

At European Springs, we can provide our clients with a broad range of materials to choose from, such as:

Aluminium
Beryllium copper

We are not just limited to our high-quality pressings; we also diversify into manufacturing springs and wireforms, all of which are made by our expert engineers and available for order online.

For many years, manufacturing companies have attempted to create a permanent solution to the labour shortage. But unfortunately, these unfilled positions have a distinctly negative impact on the industry, which is why it’s vital to find new ways of supporting people interested in starting a career in manufacturing.

At European Springs, we firmly believe in the positive effect of new people on the industry. Each individual can not only bring a unique perspective on working processes, but they can be a worthwhile investment in managing new technologies and ideas during a long and profitable career.

What’s the Manufacturing Skills and Gender Gap?

Over 270 thousand businesses exist within the UK manufacturing industry, making this industry a prominent part of the national economy and a significant part of the jobs market. However, despite this wealth of positions, there is a considerable recruitment shortage across all STEM sectors.

At the start of 2022, the British chamber of commerce predicted record-low recruitment figures as part of their quarterly recruitment outlook. These figures represented the increased recruitment difficulties that 79% of employers are struggling with, for which there are many reasons, but most commonly, it’s attributed to the lack of skilled labour.

The struggle to find skilled labour parallels the industry’s technological improvements. To remain competitive, STEM businesses are constantly exploring innovations and advancements such as cloud computing, industrial IoT and CNC machines. These improvements allow compression spring manufacturers such as ourselves to significantly optimise our work methods and process, increasing our efficiency while also maintaining higher productivity.

Unfortunately, these changes have led to skills gaps and labour shortages that were a struggle to solve. Upskilling team members into new positions has been an excellent tool for improving the adaptability of the STEM workforce. Still, we believe the long-term solution is to embrace the benefits of engineering apprenticeships.

One element of STEM industries that we strive to change is the misconception that it’s a male-orientated career choice. As expert tension spring manufacturers, we are aware that female representation in manufacturing is relatively low. However, we firmly believe that equally, both genders can bring significant improvements to our industry when the path is taken through one of our apprenticeships or as a STEM graduate initiative.

Progress on Filling the Skills and Gender Gap

Despite these issues, these troublesome gaps are slowly closing thanks to apprenticeship schemes and post-graduate initiatives. New research taken by EngineeringUK has revealed that progress is being made, with a 6% increase in female engineers to 16.5% over the comparative 10.5% reported in 2010. These percentages represent the original 562,000 women employed in STEM jobs which increased to 963,00 in 2021. This coincides with the general staff increase from 5.3 million in 2010 to 5.6 million in 2021. Additionally, thanks to various supportive initiatives, the number of female engineers has been steadily growing even when the total number of engineers dropped in 2020 and 2021.

Changes like this prove that both genders profit from successful careers in manufacturing, and employers can gain a lot from encouraging women to join them as engineers.

Examples of Success

Ireland is home to some of the best institutions for studying STEM, with the University College Dublin, NUI Galway and Trinity College Dublin all providing prestigious courses to get any woman started on her manufacturing career. This can be enhanced by exploring the many funding opportunities available to postgraduates. With the increased innovations being developed for manufacturing each year, the opportunities for female apprentices or postgraduates have never looked better, which has also had a significantly positive effect on increasing the staff numbers for STEM jobs.

Many scholarships and bursaries specifically aim to provide an accessible route into the STEM sectors. For example, Brunel University in London offers a hugely successful program for graduates as well as undergraduates called Women in Engineering and Computing (WiBEC). Since its inception, this mentorship scheme has supported over 600 female students in their goals to start careers in manufacturing or STEM.

In 2021, UCAS data provided by HESA had shown a notable increase in female STEM students to 35%, a total of 112,720 women pursuing their goals of finding a career in manufacturing or other STEM sectors.

The adoption of EDI principles has been a big step in allowing female engineers to help fill the skills gap. In addition, many manufacturers have embraced the equality, diversity & inclusion guidelines (stated in the EDI) to assist in creating a more diverse workforce.

Manufacturing Apprenticeships at European Springs

As experienced spring manufacturers, we at European Springs Ireland support these initiatives with our highly successful apprenticeship schemes. We also celebrate the 23rd of June as National Women in Engineering Day (NWED) annually because we firmly believe that everyone can enrich the industry.

Our apprenticeships follow the Mechanical Manufacturing Apprenticeship framework and award a BTEC Level 3 certificate in Engineering operations and Maintenance. Please contact us directly if you’d like to know more about our apprenticeships.

Torsion springs are one of many different designs of spring. In addition, there are many other spring models throughout the industry, and each has its unique specifications, requirements and role to play in a broad range of sectors.

Springs seem a simple tool, a common component of machinery or technology that is so common that you can practically find them in every industry worldwide. Generally speaking, they can provide a specific type of force for mechanical assemblies such as compression, extension or torsion.

These vital components are commonly considered the classic coiled compression spring, but this style doesn’t apply to every spring application. With so many spring designs available, it’s important to remember what makes each design unique.

What’s a Torsion Spring?

Torsion springs are a very different design from the commonly imagined helical spring. Instead, a torsion spring has a more compressed coil with a spiral shape. This design is to apply torque or store rotational energy.

The previously mentioned compression springs rely on linear force to push or pull and return to a designed resting position. Instead, torsion springs store and release rotational energy through torque with a measure of pressure. The torque forces a rotation on the springs axis when applying or resisting forces such as the weight of a load. The general idea is to create a similar result as the linear force in compression springs but as a rotational alternative. This is the main feature that makes torsion springs unique.

What’s the Role of a Torsion Spring?

A simple way to think of a torsion springs role is to either hold objects in place or push them back into their original resting position. When installed as a component of an application, the protruding ends of the torsion spring are attached to separate parts that are intended to rotate around the centre of the spring. This can be applied to rotations in either direction, clockwise or anti-clockwise, to suit the direction that the force or load required.

As a long-term supplier of high-quality springs, we understand how important it is that torsion spring manufacturers ensure that the spring is tightly wound. Torsion springs are also designed to offer resistance to twisting applied force as well as rotational.

Torsion Spring Manufacturing

Torsion springs are essentially wound into a tight coil, with a final sideways force applied to either a left or right-hand helix to create the unique ends of the torsion spring.

Unlike other operations, no secondary processes are required as torsion springs are ready as soon as they come off the machine, but some optional choices are available to customise your spring to suit the desired application. For example, pitching can decrease the potential for friction between closely wound coils. This allows spring manufacturers to reduce production times when creating torsion springs significantly.

Where are Torsion Springs Found?

Thanks to spring manufacturers, our homes are filled with humble domestic examples of torsion springs, such as washing line pegs, door hinges, and clipboards.

The unique specifications of this spring can be adapted to suit a wide variety of sizes and materials. The role of a torsion spring may seem very limited, but they are a very versatile component that can be found in a broad range of different industries or roles.

Torsion springs play an essential part in the agricultural sector and the construction industry. The versatility and durability of this spring design allow it to perform consistently well, even in such hardworking environments. Torsion springs are components within ploughs, tractors, fertiliser equipment and the associated sprayers. You can also find them within the various heavy plant machinery used in construction, such as excavators.

In the automotive sector, you’ll often find chrome silicon torsion springs. The combination of the material and the design of the spring helps provide a smooth movement whilst maintaining tension along the whole spring. Torsion springs can be found as parts of gear shifts, various valves, clutches and the suspension system in general.

The medical industry relies on the highest quality products from torsion spring manufacturers for much of its essential machinery. Here is where the versatility in size and design is the most critical. Micro torsion springs are commonplace for limiting the physical size of the machines. Having access to various materials is important here also. Most torsion springs used in the medical industry are made of high carbon steel to create a superior strength spring despite its limited size and are widely used in dental equipment, prosthetics, wheelchair lifts and hospital beds.
