TECHNOLOGY IN ACTION Every breath you take
Dust in the construction industry if not controlled presents a major health hazard to the users of plant, equipment and tools, trades in the local vicinity and the general public, control of Dust is paramount, whether you are using large plant or hand tools. Selecting the correct dust extraction Air movement or Air purification equipment presents a whole new experience which is not fully understood. The Preparation Group has a wealth of knowledge, products and solutions and is a leading
source of technical knowledge to advise on the best and most efficient solutions for containment of Dust whatever your machines or tools available to purchase or hire. Our high-performance filtration units and vacuums can be matched to all types of makes of
equipment or tools, to control and reduce the exposure to dust, incorporating smart technology and no handling of “Dust” by using “longopac” options on all our vacuums and filtration units.

Bunting-Berkhamsted Magnet Test and Development Centre
Bunting has invested in expanding their Test and Development Centre at Berkhamsted in the UK where they specialise in the design, test and build of a wide range of magnet and magnetic technologies.
Bunting is one of the world’s leading designers and manufacturers of magnets, magnet
assemblies and magnetising equipment. The Bunting European engineering and manufacturing facilities are in Berkhamsted and Redditch, both in the United Kingdom.
Bunting’s Berkhamsted operation is responsible for the design and manufacture of magnets,
magnet assemblies, and magnetising equipment. The range of applications for high-energy magnets and magnet assemblies continues to escalate, especially with the ongoing development and application of lower carbon-neutral energy related technology. Bunting’s experienced application engineers at the Berkhamsted Test and Development Centre continually push the boundaries of magnet and magnetic engineering to maximise performance.
Adding value through smart solutions
Business, and indeed industry itself, is constantly reacting and evolving, driving the race to discover new ways to gain a competitive advantage. While the focus is often on the ‘what’ — the physical products that come to market — Big Box Group Director Iain Gillard says the way technology is integrated is equally as vital in helping businesses achieve a more profitable future.
Automation has seen strong growth over the last 18 months and its advantages are obvious.
Picking, moving and sorting with robotics can help improve efficiencies and, ultimately, the bottom line. But there’s more to it than that, says Iain.
“Businesses face challenges every single day. Often, they want quick, cost-effective solutions
to solve it. Depending on what the challenge is, racking, handling equipment, a robot or even an entire building can plug that gap.
“However, we pride ourselves on delivering smarter solutions — making sure they are fit for
purpose but also designed to improve the situation beyond what’s in front of the client.” Big Box Group has been providing innovative solutions to a variety of businesses, from SMEs to
blue chip companies, since its formation over twenty years ago. Its ability to solve complex issues is driven by an analytical and technological approach that is both proactive and creative.
With a wide range of cutting-edge and high-performing products to hand, Big Box Group can
integrate exactly what’s needed, allowing any type of business — from manufacturing and warehousing to online fulfilment — maximise their return on investment.

To validate the correct assembly of a multipole rotor, and that the magnets are of optimum
performance, a bespoke search coil integrates the total flux measurement to produce a pass or fail test. This allows for the almost immediate 100% inspection of finished parts to any industry standard. Additionally, to check the correct fitting of all the internal permanent magnets (IPM) in a rotor, a surface flux plot more preciously and finely analyses the rotor characteristics. Although this test is slower, it is commonly used on development parts, or for statistically valid sampling programs.
To accurately assess the magnetic performance, the Berkhamsted Test and Development
Centre is equipped with an array of specialised laboratory test equipment. For magnet characterisation, a permeameter measures the Bh curve for a test specimen of ferromagnetic material by a given magnetic intensity, to permit computation of the magnetic permeability of the material. This can be carried out at temperatures up to 200°C to investigate the true coercivity of materials and validate they will perform as expected in application.

FACTORY&HANDLINGSOLUTIONS | OCTOBER 2021 67 By working closely with automotive, aerospace and other engineering companies from the
design concept stage, Bunting engineers determine the optimum magnet and magnet assembly characterisation for a given application. This includes, but is not limited to, assessing the attractive magnetic strength in different working conditions.
In an ever-increasing number of magnet applications, the working environments and
operational specifications are challenging. For high-speed magnetic rotors, Bunting undertakes a carbon fibre pre-wound sleeve burst test, determining the optimum design of wrap to securely hold the magnets.
