Having manufactured custom springs for the mining industry for decades, we are continuously building a bank of knowledge and expertise in the field. We understand that spring design for mining equipment evolves as the exploration, processing and refining by mining companies evolves.
We know that springs work in a variety of regions, for varying applications in a multitude of differing equipment and are impacted by what particular mines produce. Our experience enables us to be agile to the demands of mining machinery springs and excel at achieving spring manufacturing standards in the mining industry.
Quarry and Mining equipment covers an expansive range of machinery with demands on the spring components within them to be able to handle the toughest applications. Our spring manufacturing process features the most advanced hot and cold CNC coiling capabilities delivering quarry and mining industry springs with large wire diameters. Our processes and spring manufacturing techniques for mining applications are designed to manufacture highly engineered springs that can withstand the extreme demands of the industry and deliver on quality, endurance and accuracy.
Matching our customers world-class performance expectations with advanced production technology and leading expertise, our technical, quality, engineering and production teams enjoy partnerships with mining equipment OEM’s and suppliers. The majority of our mining springs manufacturing projects are designing, developing and manufacturing custom quarry and mining springs to excel in the extreme environments of their operation.
All our projects start with consultations; establishing drawings to meet precise specifications and designing prototypes that evolve as the product design process evolves. Performance handling assessments, technical reviews, safety testing and failure analyses collaborate to direct the demands of the precision spring and secure the right custom springs for mining application performances. Manufacturing and consistently testing samples before full production runs, is all part of the product service and customer culture we believe in to achieve product optimisation for our customers.
In the demanding and high-stakes world of quarry and mining, every second counts. The accuracy and precision of coil spring design, development, and manufacturing can make all the difference in achieving optimal performance and safety. At our cutting-edge facilities, our top-tier engineering and quality teams, state-of-the-art technologies, and advanced CNC spring coiling machines enable us to deliver exceptional bespoke spring design and manufacturing services for the mining industry. Our continual investment in our facilities and services ensures that we remain at the forefront of precision mining spring manufacturing, allowing us to optimise the performance and safety of quarry and mining equipment by pushing the boundaries of material capability and spring design.
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 mining industry springs, 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.
Our teams consistently challenge the status quo looking to new material innovations, design optimisations and customised solutions to solve spring issues within the mining industry. Determined to be at the forefront of spring innovation, we significantly invest in our people and our facilities to ensure we continue to lead in heavy duty spring manufacturing.
We are also striving towards a more sustainable future. We recognise that climate-related issues are high on the sustainability agenda of our customers, suppliers, stakeholders, industry representatives, authorities and employees and we want to be transparent about the progress we’re making to optimise our product lifecycle and transition to a lower climate impact.
We are in discussions with strategic partners concerning greater access to raw materials with a lower carbon footprint and we’re working with our customers to enhance our product development process.
Yes. This is our area of expertise. Bespoke designing and manufacturing springs for a specific application within a challenging environment is where we thrive.
3D scanners, a variety of stress testers and numerous other testing procedures allow for the scrutinising of acquired data by our quality teams to guarantee quality, accuracy and durability.
We aim for 3-4 weeks. However, material supply and demand can affect timelines.
We are world-leading heavy duty spring manufacturers, delivering the greatest expertise in compression, torsion and tension spring manufacturing.
Delivering impact to every industry, we guarantee spring solutions that will optimise your performance and success.
