Plastics Positivity at Technivation

Polymer Training and Innovation Centre Hosts UK Plastics Sector Professionals

The Technivation conference, hosted by the Polymer Training and Innovation Centre in Telford (18th April 2018), attracted delegates from across the UK plastics sector.

The Polymer Training and Innovation Centre (PITC) provides training for engineers working with plastics and has an extensive range of working equipment including moulding machines, pneumatic conveying systems, and magnetic separators.

Bunting Europe at TechnivationAt Technivation, there were talks from machinery manufacturers and also an industry update from the British Plastics Federation.  BPF Membership Services Director, Stephen Hunt, highlighted a change in the awareness and public perception of plastics since the airing of the BBC Blue Planet II series at the end of 2017.  The BPF have been working hard to clarify misconceptions about plastics, highlighting that plastic is vital in the manufacture of so many products including cars, medical equipment, and IT.  They are presently working closely with the UK Government on the proposed tax for single use plastics, which closes on 18th May 2018.

As Stephen Hunt explained, the plastics sector is the 8th largest exporting industry in the UK with a turnover of £25.5 billion.  The sector is also the 2nd largest employer in the manufacturing industry.  He also highlighted how waste from the USA and European Union combined only contributes 2% to the amount of plastic waste found in our oceans.

Delegates at Technivation had the opportunity to tour the training facility and meet representatives from equipment manufacturers including Summit Systems, Kistler, Arburg, and Staubli.  Tom Higginbottom, Bunting’s Sales Engineer, was demonstrating how to effectively remove metal from the plastics process using a combination of a FF Drawer Filter Magnet and Quicktron Metal Detector.

“At Technivation it was really good to be able to demonstrate how to remove metal and also to show how the equipment is actually installed on a working moulding machine,” explained Tom.  “We supplied the FF Drawer Filter Magnets to PTIC so that the importance of metal removal is included in the training programmes.”

Polymer Training and Innovation Centre Protected by Bunting Drawer Filter Magnet

Magnetic Separator Technology for Plastics Training

The Polymer Training & Innovation Centre in Telford has added a Bunting Magnetics Drawer Filter Magnet to the range of equipment at their plastics manufacturing training facility.  The FF Drawer Filter Magnet attracts and captures any fine and coarse magnetically susceptible materials that enter the plastics manufacturing process.

Bunting FF Grate Magnet

The Polymer Training & Innovation Centre provides polymer training and consultancy, specialising in injection moulding, blow moulding and extrusion training.  They are a technical training and consultancy business that is owned by City of Wolverhampton College.

At their Telford training facility, the Polymer Training & Innovation Centre has working production-sized plastics manufacturing equipment for injection moulding, blow moulding, thermoforming, materials handling, and a wide range of other important ancillary equipment.

Technical Trainer, Andrew Dermody, explained the importance of trainees having practical training on the equipment.

“We have great support from the industry and equipment manufacturers such as Bunting.  This support means that we can deliver practical training, with a hands-on approach, and that is the best way for our delegates to learn.  Having the Drawer Filter Magnet installed exactly as it would be in a production plant, is an ideal way to show our students best-practice and highlight the importance of metal removal.”

Bunting FF Grate Magnet

The training facility at Telford was refurbished in early 2017 and Bunting supplied the FF Drawer Filter Magnet in March 2018.  The FF Grate Magnet is bolted onto the bottom flange of a Summit Systems fed hopper.  The Magnetic Separator has a transparent front plate so that operators are able to see the material passing through or held within the system.  Virgin plastic beads fall from the hopper through two rows of high strength Tube Magnets, which attract and hold any magnetically susceptible materials.  The Tube Magnets use ultra-strong, permanent, Neodymium Rare Earth Magnets.  The cleaned plastic beads are then fed into the Engel injection moulding machine.  Removing all metal contamination ensures that the final plastic product is free from defects and reduces the amount of waste and potential damage to moulding machines.

Bunting FF Grate Magnet

On a regular frequency, dictated by the amount of metal captured, the Tube Magnets are removed as one complete assembly from the housing and cleaned.  The design of the Drawer Filter Magnet means that removal of the Magnet Assembly is quick and easy, keeping maintenance times to a minimum.

“The Bunting design is good as it is very visible,” said Dermody.  “Often Magnetic Separators are placed out of sight in hoppers, which means that they can be forgotten.  In this installation, the Drawer Filter Magnet is right in front of the machine operator and the clear front allows easy visual checking of the magnets.”

Bunting also supplied Drawer Filter Magnets for use in the classroom and the Polymer Training & Innovation Centre plan to incorporate ‘metal separation’ as one of the course topics.

The Drawer Grate Magnet is widely regarded as standard for the plastics industry and Bunting has supplied thousands to plastics manufacturing operations globally.

“It is great that delegates are able to see, in practice, the importance of having good Magnetic Separation equipment in the plastics process,” said Tom Higginbottom, Bunting’s Sales Engineer.  “Even with virgin raw materials, there is always a small amount of fine ferrous metal contamination and there is always the risk of larger tramp iron that could seriously damage the injection moulding machine.”

On the 18th April 2018, the Polymer Training & Innovation Centre is staging the Technivation event at their recently upgraded training facility in Telford.  During the day there will be a series of short technical presentations, the opportunity to experience their Polymer on-line simulation software, and the chance to meet and talk with primary and secondary equipment suppliers including Bunting Magnetics.  Visitors will be able to learn more about Polymer Apprenticeship’s and Funding and discuss their organisations own training requirements.

42 In Line Magnets Ensure Baby Food Is Metal Free

Magnetic Separators Remove Metal During Baby Food Production

A Baby Food producer based in Germany has purchased a further 14 In Line Magnetic Separators to guarantee a metal-free product.  The latest 14 In Line Magnetic Separators are in additional to 28 already supplied and installed as they equip their food manufacturing plants across Europe.

Bunting Magnetics In Line Magnet-9528In Line Magnetic Separators are designed to easily fit into an existing pneumatic or gravity fed pipeline transporting food stuffs.  Both ends are fabricated to connect with the installed pipework.  The central body of the In Line Magnet has a strong Rare Earth Neodymium Plate Magnet.

A key feature of the In Line Magnetic Separator is that there is no restriction to the product flow.  In this particular project, baby food passes through the body of the In Line Magnet and any ferrous or weakly magnetic materials are attracted by the strong magnetic field and then held against the face or the Plate Magnet.

The Plate Magnet has a tapered step, which intensifies the magnetic force and also provides an area to collect rogue metal contamination.

As the Baby Food has chucks of vegetables and meat, it was important that there was no restriction to the product flow where the food could be damaged or blockages could occur.  The Magnetic Liquid Filter, which uses Rare Earth Neodymium Tube Magnets, would not have been suitable for this application.

Bunting Magnetics In Line Magnet-9552Periodically, the captured metal is cleaned off the face of the Plate Magnet.  Access is designed to be simple and quick, with the Plate Magnet swinging away from the body on hinges.

All 42 In Line Magnetic Separators are designed for use in pneumatic pipelines up to 15 psi.  They are manufactured from Stainless Steel there are a range of standard sizes available.

“After last week’s RWM Digital Marketing Masterclass in London, we got together with Nick and the new RWM team and talked through the best way forward,” explained Dave Hills, Bunting’s Head of Sales.  “Everyone wants this show to be a success and so have taken the bold step of securing the stand opposite the entrance to the show.  Our aim is to have our stand full of working equipment to immediately capture the imagination of the visitors.”

Bunting Master Magnets at RWM17
The Bunting & Master Magnets stand at RWM17

Bunting Magnetics has been gradually increasing their presence at the show over the past 5 years.

“We started with a small stand at the back of the hall,” said Dave.  “Over the past few years our presence in the recycling industry has grown, especially when we acquired Master Magnets [January 2017].  And our stand has gradually increased in size and moved towards the show entrance.”

On the larger stand, that will greet visitors to RWM, Bunting and Master Magnets plan to exhibit a wide range of Metal Separation equipment including:

“Exhibiting working equipment at exhibitions has always worked for us,” said Dave.  “Seeing is believing and that starts at an exhibition.  Last year, visitors saw the separation capabilities of our Stainless Steel Separator and Eddy Current Separator and subsequently conducted tests in our laboratory at Redditch.  We want to demonstrate what is possible with our new and innovative technology.”

The stand at RWM18 will be the largest Bunting and Master Magnets has ever had in Europe.

“As one of the biggest manufacturers of metal separation equipment in the world, we wanted to make a bold statement.  We have some great ideas for visitor engagement at RWM and are already starting on our planning!”

Changes in E Waste Management Highlighted at IERC 2018

Future of Electronics Recycling Discussed at 17th International Electronics Recycling Congress

IERC 2018 closed on Friday 19th January 2018 with a stark warning that changes are needed in the global management of E-waste.  Attending the congress were 480 international experts from 42 countries.

WEEE E WasteBunting Magnetics Europe’s Managing Director, Simon Ayling, was at the congress for the first time.

“All the leading companies and organisations involved in E-waste were present at the congress,” said Simon.  “There was a very honest and open assessment of the present state of the industry, with a focus on what needs to change.”

Many visitors to the Bunting Magnetics stand had issues with separating Stainless Steel.

“Stainless steel is clearly a major issue when processing WEEE.  Up until now, it has been difficult to effectively [physically and economically] extract the stainless steel.  This then causes problems with shredder wear and the contamination of the end product.  With the HISC and SSSC, we have Magnetic Separation solutions for both small and large sized Stainless Steel.”

At IERC 2018, there was a focus on change.  As developing countries introduce tighter restrictions on the shipment of waste in general [EPPM – China raises drawbridge on incoming overseas plastic waste], a more holistic approach is needed.

New technology, like the Bunting Stainless Steel Magnetic Separator, and increased automation were identified as being vital to improve WEEE recycling rates.

Bunting Master Magnets at RWM17

The amount of E-waste is ever-increasing and the shrinking product size is making recycling increasingly difficult.  Rising collection costs and falling value of the end recycled product may lead to more localised e-recycling.  There also needs to be a clear political strategy with a standardisation of regulations.

WEEE E Waste“It was clear that the industry faces a challenging future,” observed Simon.  “Being able to successfully recycle WEEE can be prohibitively expensive and is further complicated with local and global environmental regulations.  Companies involved in processing E-waste are having to continually modify their businesses to survive in an ever-changing industry.  Hopefully, our Magnetic Separation technology will help.”

Metal Separation at IERC 2018

Bunting Exhibiting at 17th International Electronics Recycling Congress (17-19 January 2018)

IERC, the first major recycling event of 2018, is being held in Salzburg, Austria between the 17th and 19th of January.  For the first time, Bunting Magnetics will have a stand at the event.

During the 3 day congress, experts from around the world will discuss the latest issues facing the recycling world such as the Chinese ban on plastic waste imports and the continued drive towards electric vehicles.

Bunting Master Magnets at RWM17

Technology is always high on the agenda as new innovations make it possible to recover and separate an increasing number of valuable metals whilst reducing the amount of unusable waste.

Bunting has developed a wide range of Magnetic Separator technology.  Following the acquisition of Master Magnets in January 2017, Bunting is able to provide solutions to separate any metals.

Stainless Steel Separation

Stainless Steel becomes very weakly magnetic when bent or cut (as when passed through a shredder).  Bunting developed two new Magnetic Separators, the High Intensity Separation Conveyor (HISC), and the Stainless Steel Separation Conveyor (SSSC).  Both systems have ultra high magnetic fields that enable the attraction and deflection of Stainless Steel, enabling separation.  Production sized equipment was recently on display the RWM 17 exhibition in the UK.

Non-Ferrous Metal Separation

The Eddy Current Separator remains a vital part of any recycling process, separating and recovering non-ferrous metals.  Master Magnets have a number of Eddy Current Separator configurations enabling the separation of large and very small non-ferrous metals.  In 2017, Master Magnets manufactured and shipped a record number of Eddy Current Separators.  This is as a direct result of companies seeing their equipment’s superior separation capabilities.

General Ferrous Metal Separation

Separating metal at stages is the key to enabling the best recovery and purity of metal.  General Magnetic Separators are commonly used earlier in the process to recovery or remove ferrous metals and include:

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.

January

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.

February

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.

March

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.

April

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.

May

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.

June

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.

July

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.

August

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

September

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.

October

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.

November

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.

December

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 (press@buntingeurope.com).

Getting Metal Out of Beer

Ideal Locations for Magnetic Separators and Metal Detectors in a Brewery

Thankfully, it is very unlikely that you will ever find a piece of metal in your glass of beer.  However, when tramp metal in the form of screws and nails is accidentally introduced during the brewing process, it damages processing equipment and can even affect the taste of the beer.  In this article we look at the best methods of ensuring that the brewing process is unaffected by tramp metal.

Bunting_Magnetics_Europe_Brewery_Plant

As with any food process, there are many locations where metal can be inadvertently introduced.  With raw materials being collected from the fields and then transported to the brewery in large trucks, contamination by metal and other materials is unavoidable.

Here we look at a typical brewery and identify where Magnetic Separators and Metal Detectors could be located to remove any metal contamination.

Location 1 – Malt In-feed Line

When the malt is delivered by truck or rail, it is commonly pneumatically transported into storage silos.  A Pneumatic In-Line Magnet and/or Metal Detector would ensure that any tramp metal in the raw material feed is removed prior to storage.

Bunting Magnetics In Line Magnet-2

A Pneumatic In-Line Magnet is designed to easily fit into a pipeline without causing any obstruction.  It has a magnetically strong Plate Magnet mounted on one side which attracts and holds any ferrous metal.  This is then manually removed on a regular frequency.

The Metal Detector identifies and then ejects any remaining metal contamination, both ferrous and non-ferrous.  As most metal contamination at this stage is ferrous, installing the Metal Detector after the In-Line Magnet reduces the amount of metal detection rejects and thus reduces the loss of product.

Location 2 – Prior to Milling

cartridge_magnetsGrate Magnets are commonly positioned in or above the in-feed hopper to the mill, especially if there has been no previous metal separation or detection.  A Grate Magnet is a series of Tube Magnets designed in a grid to fit inside a hopper.  For maximum protection of the mill, the Grate Magnet uses a set of high magnetic strength Rare Earth Neodymium Tube Magnets.  Such protection ensures that no tramp metal enters the mill where it can cause serious and expensive damage.

Location 3 – Hot Water Feed to Mash Tun

Bunting Magnetic Liquid TrapWater is a common source of metal contamination in food processing plants and is also the one in-feed material that is often overlooked.  The nature of water means that rust is common and a simple Magnetic Liquid Trap is used to attract and capture any rogue ferrous metal, even in a very fine form.  A Magnetic Liquid Trap is designed to be easily introduced into a pipeline, with flanges or any other connector.  Inside the body, high strength Rare Earth Neodymium Tube Magnets project down into the material flow, attracting and capturing any ferrous or weakly magnetic materials.  The Tube Magnets are removed from the process and manually cleaned.

Location 4 – Between Mash Tun, Lauter Tun and Brew Kettle

Magnetic Liquid Traps could also be located between the Mash Tun, Lauter Tun and Brew Kettle, especially is there has been limited protection earlier in the process.

Location 5 – Hops In-feed Line

Protection is important whenever raw materials are introduced into the process and Grate Magnets and a Quicktron Metal Detector will ensure that hops entering the brew kettle are metal-free.  This design of Metal Detector is for free-fall material.  As the material enters the metal detector, any metal is detected and then automatically rejected.  The Grate Magnet reduces the amount of material lost during the rejection process by removing any ferrous metal.

Location 6 – Between Brew Kettle and Whirlpool/Settling Tank

After the brew kettle , a Magnetic Liquid Trap, with special Neodymium magnets designed to withstand high temperatures, will provide final protection prior to settling.

Location 7 – Yeast In-feed Line

As on the hops in-feed line, a combination of a Grate Magnet and Quicktron Metal Detector will ensure that any metal does not enter the process.

Location 8 – Between Conditioning Tank and Filter

To protect the filter, a Magnetic Liquid Trap is often installed after the conditioning tank.

Location 9 – Prior to Bottling

p-TRON-GM-V2As in many food processing plants, it is good practice to install a Metal Detector (in this case a P-Tron) at the final stage of the process.  This provides a final stage of protection to ensure that any metal introduced into the process from damaged processing equipment such as the filter or in the pipes is detected and removed.

This is a typical example of a Brewing Operation.  However, each plant is unique and often a site visit is required to assess and recommend the best ways to ensure a metal-free end product.
