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

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.

The drive toward increased sustainability in manufacturing has never been higher as more companies within the industry join this commitment to creating an ecologically improved and profitable industry.

This shift to a more eco-friendly approach may seem like something that has only just begun, but it has been an evolving part of the manufacturing industry in Ireland for years, with many steps being taken toward this goal.

Sustainability Goals in Manufacturing

There have been substantial announcements recently to make manufacturing far more eco-friendly. Phrases such as NetZero 2050 and the green industrial revolution are becoming commonplace as these environmentally friendly initiatives affect more of the industry.

As spring suppliers, we took a great interest in the COP26 event, which was a significant moment for sustainability in manufacturing. The COP26 event was a global United Nations summit addressing climate change and how countries plan to combat it.

COP26 was held in November 2021 in the UK after a significant delay from the previous year due to the pandemic. This is the 26^th event for the Conference of the Parties (or COP), which consists of all the United Nations countries that signed the UNFCC in 1994 (the United Nations Framework Convention on Climate change). The importance of COP is the opportunities it provides for a more effective, unified approach to combating climate change across the world and at every level of the industry. For example, at COP26, the UK launched an energy transition council. This council unites 20 governments and over 15 international institutions to support transitions and technical assistance to clean power.

How does COP26 affect the manufacturing sector? First, it has increased the already present demand for companies to embrace sustainability through decarbonisation. The new carbon NetZero targets set during the COP26 focus more on the electricity and gas parts of manufacturing’s high energy usage. This will affect manufacturing significantly within the UK as half its energy is imported.

Positive Growth

One successful way of supporting these green movements is the manufacturing industries’ attempts to create a circular economy. This is the concept of creating products more sustainably with lean manufacturing. By manufacturing from recycled materials, companies save significant energy losses compared to making every product from new, raw resources.

As all manufacturers work toward these positive goals, the real question becomes, how can it be achieved whilst still being competitive within the market? Every business needs to adapt to thrive, and discovering new ways of remaining compliant and competitive is no different. Technology seems to be the key to balancing both of these.

Technology has helped improve manufacturing in many different ways; whether it’s the development of CNC machines or assistive software, it is vital for the future of manufacturing, more so now than ever before.

Technology and manufacturing have developed a close partnership in many ways. These digital solutions have helped support the already successful lean manufacturing processes, improving their waste reduction and efficiency. Beyond the methods themselves, these technological improvements have given the industry increased visibility of its broader operations and workflows, thereby helping identify the wasteful areas and reduce emissions.

Building Profitable Relationships

As experienced gas spring manufacturers, we know that manufacturing has gained significantly from its relationship with technology. So there are potentially infinite benefits ahead through continuing this partnership, including supporting sustainability. But it’s essential that when choosing your partner, you make sure they have similar environmental goals. Exploring the environmental attitudes of your potential partners helps build a sustainable, greener workflow from start to finish.

Since COP26, technology providers have recognised the need for urgency to support sustainability within manufacturing.

When there is a unity of manufacturers, technology providers and customers that all share a vision of increased sustainability, the benefits to the environment are remarkable.

What Does the Future Hold?

Sustainability isn’t simply a single problem that can be finished. Combating climate change will require a persistent shift in operational processes and attitudes to maintain a meaningful impact. This will lead to commitments to lean manufacturing and embrace the waste hierarchy and many other ideas that support manufacturing whilst having a minimal environmental impact.

While the world’s governments are putting measures to increase sustainability, the industry must realise that it doesn’t need to wait for permission to improve its ecological status. The relationships developed between manufacturing and technology have proven to be an immensely effective tool for improvement. By exploring new opportunities, this partnership will achieve staggering results for both sides.

Metal is one of the most versatile materials used for manufacturing components. The ability to shape and process this durable material into an infinite variety of forms makes it ideal to suit any application.  

With technologies and machinery becoming more technical and complex every year, the demand for durable pressings with exact specifications has also grown. But this increased complexity means that finding off the shelf ready components for your application is almost impossible.  

Furthermore, solutions that are off the shelf will always demand that you consider their specifications when implementing them. More often than not, your vision will have to change to suit these pre-made components; that is why we offer the superior option of supplying bespoke pressings. 

What Are Bespoke Pressings? 

A bespoke pressing is a brand new part made uniquely for your purposes. These are designed and manufactured from scratch in-house so that you can be sure it’s the most economical and fit for function.  

Metal pressings, in general, are a cost-effective choice for creating a high volume of parts. Pressing or stamping is the process of moulding metal pieces into new shapes. A flat sheet, coil or blank form is placed in a stamping press, and the installed tools will form the metal into the desired shape. 

The machines we use at European Springs IE have tools unique for each product, and the overall machines are some of the most technologically advanced pressing equipment in the world. We use multi-slide and coiling machines, laser cutting, welding, tapping and grinding, and many more devices and processes to create the final product  

After the pressings have been made, they can undergo additional treatments, including the most common process, the punching. Punching is when the new metal form is punched away from the excess material, leaving only your newly created pressing behind.  

Bespoke pressings go through the same processes but give you the added advantage of customising your pressings to suit your application instead of the other way round.  

Why Choose Pressings Over Fabrication? 

There are some significant differences that separate pressings and fabrication. Pressings use the previously mentioned pressing and punching processes to form your component into what you want. Metal fabrication focuses on cutting, drilling and welding with various tools to reach the same end.  

So why are bespoke pressings the superior choice? Our metal pressings create exact shapes that get the most out of the raw materials placed in the machine. As a result, you can significantly limit the costly material wastage and save on costs by choosing pressings.  

Metal fabrication has the considerable disadvantage of being more labour intensive than computer-controlled pressings. This can also increase your costs per piece, especially when ordering a bespoke piece that may demand the use of a pressings machine, after all.  

Sectors That Use High-Quality Custom Pressings  

The development of new medical machines demanded engineering companies with machining capabilities for many years, but this has now been replaced with metal pressing and stamping. With medical innovations utilising these machines, we now have far more complex machinery saving lives worldwide.  

The automated fashion of pressings makes it excellent at maintaining exact specifications with absolute accuracy, essential for medical equipment requirements. In addition, cutting-edge microstamping has further broadened its usefulness, allowing them to be used in jaw housings for laparoscopic surgeries. 

Airbags are essential for car safety. A small but not insignificant part of a vehicle’s airbag is called the grommet. Whilst these can be made of various materials, metal is the most secure. These grommets are designed to prevent critical tearing and wire protection and assist in fitting and protecting the exceptional air pressure in the airbag. These items are an example of a bespoke metal pressing as each needs to be customised to suit the car design.  

Scuba diver suppliers will require bespoke pressing for the D-rings. With the growing variety of harnesses, suits and air tank rigs available for people of all sizes, there isn’t a single D-ring that can suit everyone.  

How European Springs IE Pressings Design Support Can Help 

At European Springs we have spent the last 65 years growing into a leading UK company for metal pressings.  We have a lot of experience manufacturing pressings to suit the particular specifications our clients require in small or large batches. The bespoke element is a part of our pressings process we’re very proud of.

For any company, it’s crucial to maintain a high level of productivity and look for ways to improve upon it each year. There are many ways your productivity can be stalled, but broken equipment needing repairs is one of the most severe.

Whether your business is in the construction, medical or automotive, a damaged piece of equipment can create damaging disruptions to your productivity. There can be several reasons for these halts, such as user error or lack of maintenance, but the quality of its components is often overlooked.

Machine Downtime

Wasted time is always terrible for any business, and when your company relies on a machine that breaks down a lot, you can find yourself enduring a lot of wasted time. Alternatively, providing machinery with faulty components to your customers can permanently damage your company’s reputation.

Having to diagnose the problem and order replacements can increase these delays and create more issues for your company’s efficiency.

Equipment downtime is costly to both time and money for you or your customers, and it can also create a continuing knock-on effect on lead-time estimates.

The best way to avoid both of these situations is by choosing a reliable manufacturer that can be trusted to only supply the highest quality components for your applications and thereby reduce any potential breakdowns immensely.

Why Superior Manufacturing Matters

There are many reasons why a manufacturer should meet the specifications required for the application. Inferior designs will not be able to last the rigours of their role for very long without breaking and needing replacing. Additionally, meeting the specification but using an inappropriate material will also have reduced longevity.

For example, as leading spring suppliers, we know that overstressing, shock loading and choosing the wrong materials are the leading causes of spring failure. And as previously mentioned, an inferior spring breaking inside your equipment will do nothing except slow your productivity and cost you time and money. There are effective ways of extending the life of your purchased components that reliable manufacturers should make available to you. To continue the previous spring example, shot peening effectively increases your spring’s density and overall tensile strength. Shot peening will prevent corrosion and reduce fatigue and even hydrogen embrittlement. Shot peening is an example of a service an experienced manufacturer can provide so you can enjoy peace of mind on your equipment’s mechanical health and focus on increasing your processes’ productivity.

Never Settle for less

All high-quality wire forms have a precise manufacturing process. Similar to springs or pressings, these are essential components for many applications and require a high level of fidelity to create a product that lasts.

Due to the exacting specifications of dimensions or material, there is no room for error in manufacturing these components. This is something that only a truly experienced manufacturer can guarantee. We at European Springs and Pressings LTD can attest to this, having been an industry leader and supplier of springs and pressings for more than seven decades.

A range of services is also a great sign of an experienced manufacturer. The ability to work with a broad range of materials and meet various extreme specifications shows confidence in their processes. At European Springs, we pride ourselves on our versatility and an immense range of springs and pressings readily available online. In addition, you can contact us directly to discuss bespoke components for more unique applications.

The Resilience of the Manufacturing Industry

The manufacturing industry suffered severe setbacks during the pandemic and Brexit. The arrival of these two events created considerable disruptions in supply chains worldwide, creating significant troubles for manufacturers globally.

There was constant risk and uncertainty with delayed deliveries and rising costs. It was a difficult time for everyone in the sector, but it also gave the industry the chance to prove its resilience in the face of strife. Thanks to the persistent dedication of spring suppliers and many other companies, the industry is bouncing back.

Increased Confidence

After this period of declining output and orders, many manufacturers within the Make UK membership are reporting that they are experiencing a significant rise, with orders and production at unmatched levels. With UK orders up to 42% and a new peak for confidence levels at 7.7, the industry is rising.

The yearly Ibec manufacturing survey conducted in October 2021 revealed that 55% of businesses had maintained the same confidence level in Irish manufacturing, with only 1 in 10 showing concerns.

As the year progresses, the combination of increased product quality and shortened fulfilment times from reliable manufacturers shows a bright future for the industry. Businesses can feel justified in their confidence in their chosen manufacturer.
