Spring Design for the Transport Industry

The safe movement of goods is essential, whether it’s freight and the warehousing and logistics of products or the movement of passengers, every purpose requires a precision designed spring to achieve a quality performance. Our expertise in spring design guarantees accuracy and exceptional quality control, with first class engineering and quality teams, technologies, manufacturing processes and advanced CNC spring coiling machines securing the right spring design for the right function.

Performance

Maximising the potential of a spring by delivering exceptional design, development and manufacturing production processes is a key part of our customer experience methodology. It is also the winning performance formula behind a spring component’s success. Our audited, tested, recognised and reliable multi-stage manufacturing process guarantees the competitiveness and quality of your product.

Durable

The repetitiveness of the work function of a spring is key to understanding the performance demands on that spring. It is also the jumping off point for our engineers and material scientists to develop a spring product that secures a lifespan that excels amongst the competition.

Precision

Our state-of-the-art spring manufacturing technology, across the very latest and widest range of large-scale CNC spring coiling machines, coupled with the most advanced spring manufacturing processes and expert engineers, provide the highest quality precision springs.

Materials

The most distinguishing property of a coil spring's material is its mechanical strength and elasticity. The four key components when considering material choice are chemical composition, surface property, tensile strength and size. These essential elements build the structure from which our engineers bespoke design springs, to meet the demands of the application of springs within the transport industry and to optimise the purpose and power.

Transport Applications for Springs

From supercars to SUVs, lorries to horseboxes, buses to road sweepers to rail braking systems and aeroplane infrastructure, there’s a tension spring, compression spring or torsion spring, likely coiled by us across multiple transportation systems throughout the world.

Suspension is a core part of our compression spring applications. However, you will also find our springs in seating, door functions, brake applications, steering systems and in a wealth of other vehicle performance functions.

Engineering & Capabilities

Matching our customers world-class performance expectations with advanced production technology and leading expertise, our technical, quality, engineering and production teams enjoy partnerships with leading industrial transportation, LCV, car and motorcycle brands.

The majority of our projects involve designing, developing and manufacturing custom springs for an essential function required for the transportation of goods - whether people, animals or trade materials.

All our projects start with consultations; establishing drawings to meet precise specifications and designing prototypes and samples that evolve as the product design process evolves. Vehicle performance handling assessments, technical reviews, safety testing and failure analyses collaborate to direct the demands of the precision spring and secure the right bespoke coil spring performance for the vehicle’s functionality and environment.

Quality Materials

The expertise of our experienced engineers is unmatched. As part of a global network of spring engineering material scientists, you can guarantee that your metal spring will perform optimally with the right material for the right function.

There are very few metal spring materials we can’t access or work with. We hold one of the largest global stocks of chrome silicon and chrome vanadium wire anywhere in the world.

We also work with a diverse range of steels, copper and titanium alloys, as well as super alloys, including Inconel, Hastelloy and Nimonic.

Precision Custom Springs

With our first class engineering and quality teams, technologies, manufacturing processes and advanced CNC spring coiling machines, we deliver an exceptional bespoke spring design and manufacturing service. Continual investment in our facilities and services keeps us at the leading edge of precision spring manufacturing. This allows us to guarantee the maximum potential out of our springs through our expertise and technical analysis on the extreme stress boundaries of material capability and spring design.

The Process

Collaboration is key and the start point of all spring design is the consultation between our technical teams and the customer. Technical designs advance through quality teams and engineers before entering the prototype phase, sample provision, testing and then mass production.

Precision Manufacturing

We’re leaders in our field because we manufacture from the highest quality wire and feature the most advanced coiling and cutting technology. This results in us excelling at spring manufacturing standards within the transport industry, delivering spring solutions that deliver the right product for the right application and guaranteeing uniformity and precision from the first spring to the last.

Heat Treatment

An essential part of the manufacturing process, heat treatment removes residual stress introduced to the material during the coiling process. The treatment stabilises the springs dimensions for greater accuracy and increased fatigue life and our oven facilities use forced convection technology to ensure the material is uniformly heat treated from surface to core. Our larger transport industry springs (such as for rail), using a wider wire diameter, require a hot winding process as the extreme heat allows large scale wire diameters to be coiled.

The process of heating up wire to approximately 900 degrees celsius, quenching in oil and tempered to complete the heat treatment, allows the spring material to be coiled to the specifications required.

Quality Control

Our quality management systems conform to ISO 9001 and our teams are experts in their field. Our global network of quality engineers ensure the spring products meet the quality standards required by the design and are the one stop shop for quality control and spring manufacturing standards within the transport industry.

More Stability

Our suspension springs smooth out the surface being travelled on, absorbing the forces generated from the road environment. This energy absorption allows for less rocking and rolling of the vehicle which also leads to less weight shifting. Weight shifting can lead to a loss of traction and as a consequence, steering can be compromised as the vehicle’s centre of gravity moves in response to the surface.

Improved Safety

Our springs are load tested using state of the art dedicated CNC spring load testers with each being regularly calibrated by third party inspectors to ensure compliance. We work within the QMS systems laid out within ISO 9001 and follow industry approved manufacturing control plans to ensure our springs comply with the requirements of the design - providing a customer guarantee of exceptional quality.

Increased Fuel Efficiency

Our wide material stocks allow us to source the most suitable alloy spring wire for manufacture. Marrying the right material choice with the latest in software design for suspension spring manufacture means we are able to produce increasingly efficient designs, resulting in weight saving, which in turn leads to increased fuel efficiency.

Enhanced Shock Absorbing

The right material choice and subsequent rewarding properties of strength, durability and performance combined with accurate post coiling processes work together to produce a stronger, lighter and more durable spring solution.

Comfier Transporting

Suspension springs absorb force, delivering a comfier transportation experience. The spring’s role is to prevent the forces generated being transferred into the vehicle, whilst maintaining traction. Quality, precision suspension springs will deliver a comfortable and quality ride.

Innovating the Future of the Transport Industry with Springs

We are very fortunate to be able to partner with leading names within the transport industry, to further our R&D through partnerships with them and in turn be at the leading edge of smart suspension thinking and systems.

Our exceptional expertise, advanced technologies, material scientists, stocks, insights and research facilities enable us to consistently explore advancements in our spring products. From lightweight materials, efficient energy recovery systems, advanced braking systems, noise reduction and active aerodynamics, we are working on a number of projects that explore all these factors. We will continue to develop these areas further to guarantee our position as the best solution for our customer’s transport spring needs.
