Supporting Year of Engineering

Finding Our Future Engineers

In November 2017, the UK government announced that 2018 will be the Year of Engineering, a national campaign to increase awareness and understanding of what engineers do among young people aged 7-16, their parents and their teachers.  This is part of a year-long campaign to tackle the engineering skills gap and widen the pool of young people who join the profession.


At Bunting Magnetics and Master Magnets, we depend on the skills and experience of our engineering team.  Our future as a business is dependent on young people entering engineering.

To support the Year of Engineering, we plan to use photographs and videos to highlighting the importance of engineering in our everyday world.  Each month we will focus on a project where engineering ingenuity has resulted in the development or enhancement of a product and solved a problem for one of our customers.

The Art of Metal Separation

The vast majority of our design work revolves around Magnetism.  By utilising magnetic forces and principles we design and manufacture systems that can separate and detect metal in a non-metallic material.  In some applications, we can even separate individual metals.  These are called Magnetic Separators and Metal Detectors.

Our first photographs and video focus on solving the problem of Metal Contamination in a plastics production process using the FF Drawer Magnet.  This Magnetic Separator has been designed to remove small and fine ferrous metal contamination from dry free-flowing materials such as plastic beads and even foodstuffs.

The FF Drawer Magnet has two key constituent parts:

  1. The outer fabricated metal housing;
  2. The internal high strength Tube Magnet assembly;

The outer body is designed and drawn by engineers in our drawing office based upon information provided by external Sales Engineers.  The internal engineering team will consider how the Drawer Magnet is going to fit into the customer’s production line looking at the overall size, type of connections, and accessibility.  This is then built by one of our skilled fabricators using the drawings.

Drawings are also provided to our assembly team to construct the high strength Tube Magnet assembly.  The high power of the Neodymium Rare Earth Magnets mean that care is needed and the assembly is only undertaken by skilled engineers.

Bunting FF Drawer Magnetic Separators

Our fabricator then combines the housing and the Tube Magnet assembly and it is ready for despatch to the customer.  Once arriving on site, the customer’s own engineering team will install the Magnetic Separator.

The Importance of Engineering

Engineers are involved in every stage of solving the metal contamination problem.  Capturing the problematic metal has significantly reduced the amount of waste and has protected delicate processing equipment.  For the customer, the Magnetic Separator is now a vital part of the process.

This is just one of many projects our engineers work on every day.

Our 2017 Review

A Look Back at Our News & Blogs from 2017

2017 has been another busy and exciting time for Bunting Magnetics Europe with some great news stories.  In this blog we look back at the past 12 months and review the stories that hit our headlines.


bunting_master_magnetsWe started the year by announcing that Bunting had acquired leading UK Magnetic Separator and Metal Detection company Master Magnets.  This changed the Magnetic Separator landscape in Europe.

At the same time, the Bunting team was exhibiting at the Arabplast exhibition in Dubai.  The plastics focused event was attended and visited by plastics professionals across the region.  Sales were even made on the stand!

Our 7th of our 8 Magnetic Separator Myths examined the impossibility of achieving 100% metal separation.

To finish off January, we announced record sales in 2016 despite the backdrop of Brexit and political uncertainty.


We started the month with our 8th Magnetic Separator myth, asking if it was possible to block a magnetic field.

Bunting also joined the British Plastics Federation, reflecting our longtime involvement in the sector providing metal separation solutions.

Bunting at Exposolidos 2017

Our exhibition focus in the month was Exposolidos in Spain with our local representative SMED Tecnica.

In February, we also asked the question of whether our Environmental future is simple down to design?  This was written in response to the growing awareness of the environmental impact of waste that would gradually intensify through the year.

We finished off the month with the launch of the Teardrop Tube Magnet, ideal for use in fine powders where bridging might be an issue.


The strength of a Magnetic Separator is often expressed in ‘gauss’.  However, the vast majority of people are unable to measure gauss and so we showed a simple practical way to check the magnetic power using a simple spring balance.

Our 9th Magnetic Separator myth highlighted the dangers of strong Magnets and our 10th myth looked at ways to easily and safely clean captured metal off  Magnetic Separators.

We also investigated a US FDA report stating the ‘Ingesting Metal Fragments Can Cause Injury‘.

In March, we exhibited at the Southern Manufacturing and Electronics show in Farnborough UK.


Metal is commonly found in spices and we examined a typical plant and identified the best locations for Magnetic Separators and Metal Detectors.

We also reported that we sold a record number of Plate Magnets in 2016 for export to Indonesia and 28 In-Line Magnets to a German baby food producer.

New Bunting Sales EmployeesWith the continued growth of the business, we were thrilled to announce the appointment of two new sales engineers, Tom Higginbottom and Gordon Kerr.

In April, UK supermarket Morrisons was hit by a metal-in-food scare and we looked at how this could have happened and ways in which such a problem could have been prevented.


Our Food Safety theme continued in May when, during a metal separation survey, we found large amounts of metal safely captured when processing rice.  Our Perfect Plant review assessed the best methods and equipment location to ensure that metal is removed from Processed Vegetables.

Exports continued to proved successful with the shipment of a HFS Drawer Magnet to a Plastics recycling company in France.

Our technical review in May reviewed the effect of high temperatures on Rare Earth Magnetic Separators.


There was a political flavour to news in June after the UK’s general election and we investigated what the leading parties were promising with regards to the environment.  At the same time, Bunting and Master Magnets were jointly exhibiting at Waste 17, a major UK recycling show in Manchester.

The week after, Bunting supported local representative BMS France at the FIP Solution Plastique exhibition in Lyon, France.

To mark the UK’s Food Safety Week, we reviewed recent cases of ‘metal’-in-food’ and the potential implications for the manufacturer, sales outlet, and customer.


Denis_Elkins_Bunting_Magnetics_Europe-2176In July, we were thrilled to announce the successful transition to ISO9001 2015 Quality and the ISO14001 2015 Environmental Standards.

In the media there was increasing attention on the issue of plastic waste in the environment and we commented on the necessity of a global strategy for Plastic Waste.


The environmental theme continued in August asking if the UK could realistically increase their metal packaging recycling rate by 10% by 2020.


As a prelude to RWM17, the UK’s largest waste and recycling show, we looked at 3 UK Waste and Recycling Facts such as asking how much waste do we actually generate?

Bunting Master Magnets at RWM17

After exhibiting at RWM, there were many questions being asked by exhibitors and visitors about the future of the event despite the importance of recycling and the global waste problem.


Bunting Magnetics Europe at Interplas 2017

The UK’s leading plastics show, Interplas, is held every 3 years and, as in previous years, it was very well supported by both exhibitors and visitors.  The environmental issues associated with plastic waste was gathering momentum.

Removing metal from fine powders can be extremely difficult and we produced a technical report looking at the best techniques and ideal equipment.

Tom Higginbottom attended the successful Bulk Solids & Powders show SyMas in Poland with the local Bunting representative TEKPRO.


The Manufacturing and Engineering industries have been concerned about the lack of young engineers and hopefully initiatives such as Tomorrow’s Engineers Week will help address this issue.

We were also excited to report two consecutive record sales months in September and October.  2017 was proving to be as successful as 2016.

Our latest Perfect Plant review focused on the brewing of beer and ensuring that all metal is removed to protect delicate processing equipment and the taste of the beer.


Pantomine BlogThe BBC TV series Blue Planet had highlighted the global problem of plastic waste in our oceans.  However, as the pressure increased on the plastics sector, we asked whether Plastic was the Pantomime Villain of the recycling world?

We hope you have enjoyed reading our news and blogs in 2017.  If there are any topics that you would like reviewed, then please get in touch and send an email to Paul our press officer (

Stainless Steel Isn’t Magnetic, or Is It?

4th of 10 Magnetic Separator Myths

The vast majority of stainless steel used in plants processing foodstuffs, chemicals, plastics and handling bulk materials whether in solid, liquid or powder form, is non-magnetic.

Or is it?bunting-magnetics-europe-ltd-ffs-magnet-0086

Traditionally, Magnetic Separators were installed to remove any ferrous metal.  Today, this has expanded to include any magnetically susceptible material, including magnetic plastic, used for gloves and even tools.  Magnetically attractable metals come in the form of steel or iron and are strongly attracted to the surface of a magnet.

However, as the attractive strength of permanent magnets, such as Rare Earth Cartridge Magnets has increased, analysis of the captured metal has shown that stainless steel is present.  So how is that so?

Most stainless steel ending up in a process line originates from broken or worn processing equipment and is often small in size.  During the process of being broken or worn, this abraded stainless steel has been work-hardened.  This results in a slight change in the metal causing it to be very weakly magnetic.

With the right design and strength of Magnetic Separator, weakly magnetically susceptible materials such stainless steel can be attracted to the magnet face and captured.  Even ‘non-magnetic’ stainless steel bolts are found to be very weakly magnetic on the head of the bolt, especially if a spanner or socket has been used for tightening and loosening.

So even though a Magnetic Separator will not capture all stainless steel, those with a high magnetic attractive force (eg Rare Earth Magnets) will attract and capture a high percentage.  This is ideal when trying to reduce the amount of metal passing through final stage Metal Detection.

Better and Cleaner Magnetic Separation at Vulcanis

Twin Pole Bunting Magnetics Overband Magnet Enhances Recovery

Vulcanis has designed and built a recycling plant to receive and recover steel and aluminium cans in Barking, UK, and purchased a Cross Belt Overband Magnet for steel can recovery from Bunting Magnetics Europe Ltd.

Presently, consumers in the UK use approximately 13 billion steel cans and 50 billion aluminium cans per annum and recycling rates are 61% for steel (Tata 2014) and 57% for aluminium (Alupro 2014).  For steel in particular, the UK government has set a target of 76% recovery by 2017 and to achieve this objective more recycling plants and initiatives are needed across the UK.

The inspiration for the new plant came from Vulcanis Managing Director, Mena Ramsis.  He explained, “I was not involved in the recycling industry and only became interested when I was attending a wedding and wondered what happened to the waste.  When I started researching I could see that there was a need for additional recycling centres right across the UK and decided to build the Vulcanis plant in Barking.”

The whole plant was designed and built by in-house engineers after two (2) years of global research and includes equipment sourced from three (3) continents.  A key part of that research focused on separation equipment including the Magnetic Separator for steel can recovery and Vulcanis ordered the Cross Belt Overband Magnet from Bunting because of the strength and design of the magnetic circuitry.

Permanent Magnets, which are suspended over conveyor belts to attract, lift and dispose of tramp steel and iron, are used, extensively across the recycling industry.  A Cross Belt Overband Magnet consists of two pulleys either side of a magnetic box.  A belt then runs around the pulleys, driven by either an electric or pneumatic motor.  Metal is attracted up onto the surface of the magnet when it meets the rotating belt.  Cleats on the moving belt then move the captured metal away from the conveyor and out of the magnetic field where it is discharged into a collection bin.

Bunting Vulcanis-1179-2

When Vulcanis researched Magnetic Separators, they found that the Bunting design was fundamentally different to those proposed by most other suppliers.  The most common design of Cross Belt Overband Suspended Magnet uses a magnet box that projects a single magnetic field down onto the conveyor belt.  This is otherwise known as a ‘Single Pole’ magnet and is used commonly on mobile crushers.

Vulcanis identified that the separation performance of traditional ‘Single Pole’ magnets was limited and if recovered steel cans failed to get lifted when passing through that single area of maximum magnetic intensity, then they were missed completely.  The Bunting ‘Twin Pole’ Cross Belt Magnet projected two separate strong magnetic fields down onto the surface of the conveyor belt and so doubled the chance of capturing the steel cans, thus maximising recovery.

Ramsis first met Bunting at the RWM exhibition in Birmingham and was immediately impressed with the professionalism of the Bunting team.  Carlton Hicks, the Bunting UK Sales Manager, demonstrated the strength of the Cross Belt Overband being displayed on the stand and after assessing similar Magnetic Separators on other stands at the show, Ramsis quickly concluded that the Bunting design was magnetically superior and stronger.

Ramsis was impressed with the Bunting team, “Carlton and his colleagues were really helpful at the RWM exhibition and took time to demonstrate their equipment.  They made us feel welcome.  I recall my father betting Carlton £10 that he would be able to remove a bolt from the surface of the Cross Belt Overband Magnet.  Firstly, they held the bolt at 250mm and it shot up onto the surface of the magnet.  And then my father tried to remove it, which he couldn’t.  I don’t believe that the bet has been paid as yet, although we did buy the Overband!”

The Vulcanis plant is designed to receive 2 tonnes per hour of mixed materials with no organics.  The materials are received from across the UK, including as far north as Glasgow, often from existing recycling plants that are unable to produce a clean end product of separated metal or plastic.  Plastic recycling companies send Vulcanis by-products, often destined for landfill, who then process the material, removing all the metal, before selling the clean plastic back to the by-products supplier.  Due to the variable infeed, the split of the plastics, steel and aluminium output varies considerably on almost a daily basis.  Presently, approximately 10% of the infeed to the plant goes to landfill, whilst the aim is to reduce this to zero.

Despite only starting receiving materials in late summer 2014, the plant is already at 40% capacity, operating 8 hours per day, 5 days per week.  The output material of steel and aluminium is over 99% pure with a very high proportion being exported.

Bunting Vulcanis-1134-2Mena Ramsis explained the reason for their success and their vision for the future, “When I had the first idea for the plant, the support I had from my family was amazing.  I have always been inspired by my Grandmother and Father and they gave me the confidence to develop something that many people doubted would be successful.  We are building our business by offering our suppliers and partners favourable commercial terms and on the basis of opening up new opportunities for companies to reduce their waste and recover more material.  The response from the industry has been incredible and we are already looking at expanding the plant.  Our aim is to be processing 12 tonnes per hour in the next 5 years.”

Carlton Hicks added, “Working with Mena and Vulcanis has been a pleasure.  Their attention to detail has been acute and this meant that we were able to demonstrate that the Bunting design of Overband Magnet was exactly what they needed to maximise steel can recovery.  Although I am still waiting for my £10.”

Bunting Magnetics designs, manufactures and supplies a wide range of metal recovery and separation equipment for the recycling industry.  For further information, please contact the Bunting sales team on:

The benefits of a Twin Pole Overband Magnet

The Bunting Product of the Month for February 2016

The Overband Magnet is one of the most commonly used Magnetic Separators in the world and is found suspended over conveyor belts transporting materials such as aggregate, household refuse and woodchips.

Bunting Overband Magnet over Conveyor

The basic design of an Overband Magnet has a Magnet Block positioned between two pulleys over which runs a rubber conveyor belt.  The conveyor is driven either with a hydraulic or electric motor and enables ferrous metal attracted up to the face of the Magnet Block to be transported away from the conveyor and discarded.

The magnetic magic of an Overband Magnet is the design of the Magnet Block.  The vast majority of Overband Magnets have single pole Magnet Blocks, but the Bunting design is different.

Bunting Overband Single and Twin Pole Magnetic Field

The Bunting Overband Magnet has a Magnet Block with two magnetic poles.  This is more difficult to manufacture and uses more material, but enables an enhanced level of separation.  In certain applications such as removing nails from conveyed woodchips, the Twin Pole Overband Magnet is the only suitable design.

So when should a Twin Pole design of Overband Magnet be considered?  If the following is important, then a Twin Pole Overband Magnet design should be used:

  • Maximum separation of ferrous metal to protect processing equipment such as a crusher;
  • When separating ferrous metal that is long and thin (such as nails from woodchip).  A Single Pole design will result in nails hitting the conveyor on the point and sticking into the belt;
  • Maximum recovery of ferrous metal such as in refuse and MRF recycling operations;

A selection of photographs of installed Bunting Overband Magnets can be seen on our Pinterest and Flickr social media channels.

Can the UK Match Brazil for Aluminium Recycling?

Record Breaking Aluminium Can Recycling in Brazil

This news in Recycling International must have raised a few eyebrows in the UK and European recycling communities.  Even though Brazil has been the number 1 Aluminium Can Recycler since 2001, the latest reported figures of 98.4% recycling is very impressive.  Maybe even more so when you consider that the EU recycling rate of Aluminium UBCs is around 70%.


Reclaim, Recover and Recycle continues to be the mantra of European governments and although huge advances have been made in the past decades, reaching politically set targets appears to be difficult. And yet a developing country like Brazil, with considerable social and economic challenges, has nearly been able to achieve the impossible 100% recycling target.

In the UK, a large proportion of Aluminium UBCs are recovered through Materials Reclamation Facilities (MRFs).  The feedstock to these recycling operations varies considerably from well pre-sorted to almost mixed waste.  There is no single UK waste strategy and each local authority pursues their own individual recycling agenda.

Within the recycling process of a MRF, most use a Non Ferrous Metal Eddy Current Separator.  This Magnetic Separator operates on the basis of material being conveyed into a strong and rotating magnetic field which then causes the aluminium to be propelled away from non-metallic material.  The separation is very dynamic and impressive to see.

However, the success of the Eddy Current Separator is dependent upon the presentation of material.  This means that deep heavy burdens of waste will commonly result in poor levels of recovery and low metal purity.  Presentation is key.

In practice, many of the recycling operations are focused and judged on material throughput and not recovery and this means that equipment like the Eddy Current Separator is often overloaded and, therefore, under-performs.  It is a common problem and a challenge for many MRF operators.

Again, the success of recycling comes down to which targets are set and maybe this is where Brazil has got it right.

Bunting Exhibition Success at Southern Manufacturing 2016

Magnets, Magnetic Separators and Magnetic Assemblies Generate Interest

Bunting Europe’s Head of Sales, Dave Hills, was thrilled with the response and level of interest at the Southern Manufacturing & Electronics Exhibition held at FIVE in Farnborough between the 9th and 11th February 2016.


“We generated 50% more leads than in 2015 and the quality of those leads is higher,” stated Hills.

“There was a great deal of interest in magnetic assemblies, including one from a German company who had travelled to the UK specifically to find potential suppliers.”

“Many visitors were actually surprised that we manufacture and design magnets and magnetic assemblies in the UK.  Sadly, over the past two decades, the number of companies in Europe with such magnet manufacturing and design expertise has fallen dramatically, with most supplies now coming from China.  Being at the show gave us the opportunity to stand up and shout about our UK manufacturing prowess, which was fantastic!” explained Hills.

“What we find is different about the Southern Manufacturing and Electronics show is the diversity of the visitors and exhibitors.  We have 3 distinct and very different product groups [Magnetic Separation & Metal Detection; Magnets & Magnetic Products; Magnet Production & Magnetic Assemblies) and this is the only show where we have interest right across our range.  We had a number of leads from plastic injection moulding companies for Magnetic Separators and Metal Detectors to remove metal contamination.”

Hills is excited by the new opportunities.  “We met many customers and companies with whom we are already in discussion with regards to specific projects.  Since the show finished last week, our sales team has visited several companies who came to our stand.  The potential is fantastic!”

Photographs from the exhibition can be seen on the Bunting Photo Gallery.

Magnetically Fanning Sheet Metal but How?

Helping Manufacturing Productivity and Safety with Magnets

Handling and prying apart ferrous metal sheets can be difficult especially if they are oily or polished.  The Metal Sheet Fanner uses magnetic forces to induce a magnetic field into the ferrous metal sheets, creating magnetic poles that then repel each other.  This then causes the end of the metal sheets to ‘fan’, enabling fabricators and operators to then easily select one sheet at a time.


There are different models, sizes and designs to suit a wide range of Metal Sheet sizes and operation environments.  These include:

  • Standard Sheet Fanners for manual handling operations;
  • Sheet Fanners for use on robotic lines that can be turned on and off;
  • Machine mounted Sheet Fanners;
  • Pivoting Sheet Fanners which are ideal for irregular shaped parts;

Bunting recently displayed and demonstrated the Magnetic Sheet Fanners at the Southern Manufacturing show in Farnborough, UK and shot a video showing a simple demonstration showing how a Magnetic Sheet Fanner works.

Magnetic Demos at Southern Manufacturing

Bunting Magnetics Showing Exhibition Visitors the Magnetic Magic of the Metal Sheet Fanner

Demonstration has been key on the Bunting Magnetics Europe stand (U74) at the Southern Manufacturing exhibition being held at FIVE in Farnborough between the 9th and 11th February.

The equipment is simple.  It is a Magnet that simply splays metal sheets to make it easier to handle.  The Metal Sheet Fanner is nothing more than that.  However, manually trying to separate sheets of potentially oily steel can be a nightmare.  Try it or ask any fabricator.

This makes manufacturing life easier, improves productivity and makes the workplace safer.

To see how the Metal Sheet Fanner works, please drop by stand U74 at the show or take a look at the YouTube video.

For further information on what sizes of metal sheets can be handled and how the Metal Sheet Fanner can be installed, please contact our technical sales team on:
