Undisclosed challenges and considerations that mould tool sellers face

In the ever-evolving landscape of sustainable manufacturing, Luxus stands at the forefront as a pioneer in recycled plastic compounding for nearly six decades. With a commitment to innovation and environmental responsibility, Luxus has become a trusted partner for companies looking to integrate recycled plastics into their manufacturing processes. However, there are critical aspects of the compounding process that often go unnoticed, particularly when it comes to the specifications of mould tools. In this blog post, we uncover the undisclosed challenges and considerations that mould tool sellers may not always share, shedding light on the intricacies of recycled plastic compounding. 


Hot Gates: Size Matters, but Shear Matters More 
One of the key considerations in mould design is the size of hot gates, which can significantly impact waste reduction. Smaller hot gates may seem like an eco-friendly choice, but there's a hidden trade-off: increased shear. Shear, in the context of plastic compounding, refers to the degradation of the polymer during processing. The finer the hot gates, the higher the shear forces, leading to potential issues such as physical imperfections like splashing and silvering marks. 

We understand the delicate balance between waste reduction and material integrity. With 59 years of experience, we can navigate these challenges and develop customized solutions that meet your specific needs. By knowing your requirements, we can specify materials and create grades that optimise performance while minimising the impact of shear forces. 


The Complex Conundrum of Melt Temperature 
Complex mouldings often demand higher melt temperatures, but this comes at a cost – reduced physical properties like impact strength. Some mould tool designers may specify running materials at hotter temperatures without fully considering the consequences. Luxus materials can be tailored to accommodate higher temperatures, but again, this requires collaboration and knowledge sharing. The more we know about your project's intricacies, the better equipped we are to design materials that strike the right balance between complexity and performance. 


Residence Time: A Crucial Factor in Degradation: 
Residence time in the barrel is another critical factor that can contribute to polymer degradation. Extended and high-heat residence times can lead to a mass of degradation issues. At Luxus, we strongly advise against prolonged exposure to high heat unless we are informed and can adjust our material formulations accordingly. Transparent communication about your manufacturing process allows us to optimize our compounds for your specific conditions, ensuring the longevity and quality of the final product. 

 
Knowledge is Power, Collaboration is Key 
In the world of recycled plastic compounding, knowledge is power, and collaboration is key. We invite manufacturers and mould tool designers to open a dialogue with us. By sharing your requirements, challenges, and specifications, we can work together to develop solutions that not only meet but exceed your expectations. The more we know, the more we can help you achieve your sustainability goals without compromising on quality or performance.

Rob Flynn Retires After 22 Years With Plastics Processor
Rob Flynn (65) from Louth retired this week after 22 years with Lincolnshire based technical plastics recycler and compounder Luxus Ltd.

Commenting on his time with Luxus Rob Flynn said: “It has been a pleasure working for Luxus these past 22 years and to have had the added benefit of being employed by a major manufacturer based here in my home town, Louth. I’d like to thank everyone for their support; I have always enjoyed being part of the Luxus team.”

Originally from Cumbria, Rob Flynn trained as a joiner restoring antiques furniture before he began his employment with Luxus on the 5th July 1993. He worked initially as an Extrusion Operator, which he did for 10 years before moving to the blending team to broaden his experience.

When asked to give advice to future machine operators he continued: “If you’re thinking of a career in plastics processing you need to get on with everyone, show up on time, work hard, but most importantly, be prepared to listen too.”

In recent years Rob took the decision to semi-retire so he worked instead as a Yard Operative, a role made possible thanks to the support of all his colleagues.

Luxus Managing Director, Peter Atterby, said: “Rob’s continued support has been invaluable over the years. We’d all like to wish him the very best for his retirement.”
Rob now intends to take up joinery once again, but this time for his own interest.

Luxus employs 155 staff and has a turnover of £25m based at the Fairfield Industrial Estate, Louth, Lincolnshire. (www.luxus.co.uk)

Hycolene™ Surpasses Expectations In First Commercial Trial
9th November 2015

Luxus is pleased to announce that its high performance recycled content polymer range, Hycolene™ has surpassed expectations in its first full scale commercial trial that took place in September at moulder IAC’s plant based in Lincolnshire.

Hycolene is a faster cycling range of scratch resistant, lightweight (PP) compounds that help deliver improved Life Cycle Analysis (LCA) - it features up to 60% recycled content. The range has been developed to target Europe’s automotive interior trim market, by helping to satisfy both ‘end-of-life’ vehicle (ELV) and emissions targets.

The first full scale commercial results have shown that the scratch performance of Hycolene has significantly improved on the current product. It will therefore deliver a high quality finish; a key requirement given design and aesthetics are increasingly important in the cabin.

The trial also demonstrated that Hycolene can produce a much faster cycle time delivering moulders a substantial 8-12% saving, as more parts per tonne can be processed - satisfying Tier 1 targets in addition to OEM’s lightweighting requirements.

Dr Christel Croft, technical director at Luxus, comments: “These results have confirmed that the enhanced performance of the Hycolene range has not only been maintained, but in some instances have surpassed expectations.

“It has shown too, that Hycolene can really help improve life cycle analysis, since this ‘tool’ takes into account all the factors affecting a product’s environmental footprint. It also has the potential to be used as a true ‘drop in’ solution by Tier 1’s.”

Luxus announced earlier this year, that it has as part of a consortium recently secured a €1.4m investment, co-funded by the EU Eco-Innovation initiative, part of the EU's Entrepreneurship and Innovation Programme (EIP). Its members are injection moulding company IAC for materials trials, twin screw manufacturer Coperion for technical support and Jaguar Land Rover offering end user guidance.

The commercial trial followed initial scale-up tests, these focused on different formulations, screw designs and process conditions at Coperion’s pilot plant based in Stuttgart in the Spring this year. The results were then jointly analysed by Luxus and Coperion before recommendations were made to the rest of the consortium to agree that the first commercial trial could take place.

For the trial itself, identical formulations, screw design and process conditions were created using Luxus’ bespoke Coperion extruder to establish scale-up parameters. This was to ensure the best environment for the first full scale batch to be used by IAC for its moulding trial. The consortium partners all agreed that the column shroud should be adopted for this trial since it’s a critical class ‘A’ visual component in the cabin.

Dave Jenkins, product engineering, International Automotive Components Group Ltd, comments: “From my perspective this was a very encouraging first trial, although further trials are required to fully optimise the product. A range of components also need to be run, so we can understand the material’s strengths and weaknesses. These will commence once the initial component lab testing is completed satisfactorily.”

As for the future, the next step is to repeat the commercial production improving screw design and process conditions following these initial results to improve material qualities. Luxus will then produce different grades of Hycolene and work with IAC to produce further parts for statistical analysis.

Luxus technicians will also be considering new markets where lightweighting and scratch-resistance are of benefit such as the educational furniture market for example.

OBITUARY: PLASTICS PIONEER RONALD TONN
Ron Tonn - plastics recycling pioneer and founder of Lincolnshire compounder and recycler Luxus, died suddenly on Wednesday 12th August 2015 from heart failure. He was 83 years old.

Born in Chicago in 1932 amidst the Great Depression, he went on to become a US army veteran having seen active service in the Korean War in his early twenties.

Ron Tonn, whose career in plastics spanned five decades began trading in polymers for American based Muehlstein in the mid 1950’s. He was subsequently sent to the UK to help manage the company’s European arm at the age of 25, which he headed up just a year later.

He was later to establish his own business, Luxus on the 15th January 1965. The name Luxus came from his German grandmother, since she often described him as her ‘Du bist ein luxus kind’ which literally translates as luxury’s child.

At the company’s incorporation, it became his ‘luxury child’ since he didn’t have sufficient finance for such a venture at the time. Luxus was also a preferred brand name adopted by German manufacturers to suggest luxury e.g. The Opal Luxus.

Ron Tonn’s early projects included doing a couple of national TV adverts in front of the camera for major household names Oxo and St Bruno Tobacco. A long term income however, would not come from that route.

Then one day he received a call from an old Muehlstien contact offering him a parcel of substandard polyethylene to sell. He knew instantly how to find a willing buyer and so another offer quickly followed. Both deals realised more profit than he had made in the previous two years - his new venture was born.

His burgeoning plastics recovery business was quickly growing, so he approached a small granulation company Mavelat, to fulfil its custom granulation work. This was done from its factory based in St Albans that was later to relocate to Eve Street in Louth in 1967. At that time everything was loaded by hand out of Louth with a lot of export going via rail.

Peter Laking, engineering and project manager at Luxus recalls those early days: “We always had the upmost respect for Ron. He was never afraid to get his hands dirty, he’d help with the granulator work if needed and wanting to understand everything there was to know about the materials we were using.

“More than that, he wanted to incentivise us all too. In the early days when we were sifting powder, he said “If you can sift 10 tonnes a day I’ll buy you a bottle of whisky!” When we did he bought the team a gallon of whisky – those were of course very different times!”
Ron Tonn often described coming to the UK as his true ‘rebirth’, since it marked for him a fundamental shift from simply trading  plastics in the ‘old days’ in America. Luxus was instead about recovering existing waste plastics by re-engineering material that would otherwise be destined for landfill.

The mantra ‘reduce, reuse and recycle’ was gaining popularity in the mid 1960s. The time was right for Ron Tonn’s sustainable ethos. Marking the beginning of what we now understand as today’s plastics recovery industry.

He was later to become a British citizen too, proof enough of his belief in his business and his affection for his newly adopted homeland.

Modernity came when Luxus had the opportunity to purchase nylon scrap from pads used for rail tracks laid on concrete tiles for a ready market in America. This required joint investment in a heavy duty granulator, so a formal partnership with Mavelat began.

Luxus however, was soon to do the bulk of the business so the joint venture quickly became cumbersome for this entrepreneur. Ron Tonn then had to raise the necessary funds to buy out of the Mavelat partnership which he did manage to secure. This as it happens was great timing, just before the 1970’s oil crisis when demand for recycled plastics was to spiral.

In 1976 Luxus was one of the first businesses to buy premises on the Fairfield Industrial Estate in Louth. Ron Tonn continued to manage the business successfully despite the subsequent 1980’s recession before retiring in 1997. His true ‘back to the floor’ approach to decision making has been passed to its present managing director, Peter Atterby.

Peter Atterby, managing director, Luxus, described Ron Tonn as “a dear friend, a great and charismatic man and one of the UK’s few genuine plastics recycling pioneers. Ron created a business that was managed largely by hand in the early days to one that was at the very forefront of technology accelerating with a growing plastics industry. Luxus as a result, became a true leader in its field. He will be very sadly missed.”

The business that Ron Tonn started as a young American entrepreneur turned 50 this year. At its golden anniversary celebration, he paid tribute to his predecessor Peter Atterby, he said: “That man has taken it (the company) such a distance since he took over the reins. It is totally unrecognisable.”

Today Luxus is a £25m turnover business operating in global markets and still fulfilling its founder’s pioneering vision for a more sustainable future.

Luxus Shows Next Generation Sustainable Thermoplastic (PP) Lightweight Materials At Auto Interior Expo 2015
~~16th June 2015

UK based technical compounder and recycler Luxus, will be showing on stand (A5126) the progress it’s made on the road towards delivering next generation lightweight and sustainable materials to drive tomorrow’s auto interior innovation - the result is Hycolene™ a new sustainable lightweight thermoplastic (PP) range.

Luxus has as part of a consortium recently secured €1.4m investment co-funded by the Eco-innovation initiative of the EU for its Recyclite project (www.recyclite.com). The aim is to commercialise the development of its Hycolene range of lightweight (PP) compounds with up to 60 per cent recycled content to target’s Europe’s class ‘A’ automotive interior trim market.

Luxus will be collaborating on the commercialisation project with twin screw manufacturer Coperion to help with complex processing, tier 1 moulding supplier IAC for materials trials and Jaguar Land Rover. The automotive manufacturer will be providing end user guidance on the project to ensure the technical requirements are met, allowing exploitation of this technology across future automotive industry applications.

Robert Crow, Group Leader , Materials Innovation at Jaguar Land Rover described the Recyclite project as, “A ‘double win’ because the use of recycled material and lower weight of the compounds are both beneficial in Jaguar Land Rover’s programme for reducing the environmental impact of its vehicles.”

Project Manager, Dr Christel Croft at Luxus will be presenting a seminar on the Recyclite project as part of the Interiors Innovation and Design Forum, ‘High performance lightweight recycled polypropylene materials for tomorrow’s auto interiors’ at 11.45am, on Thursday 18th June 2015 at the Auto Interiors Expo 2015.

The key technical benefits of the Hycolene range are as follows:

• Significant weight reduction - up to 12% per part
• Increased recycled content – up to 60% per part
• Excellent stiffness/impact balance and improved scratch resistance
• Similar dimensions – a drop-in solution and colour matching

Peter Atterby, Managing Director, Luxus explains: “We are pleased that the commercial potential of our Hycolene range has been recognised by the EU. This investment has enable us to effectively make a fundamental step change in our technology as we aim to replace our filled compounds with next generation reinforcing additives.

“These additives offer excellent tensile properties that don’t detract from the appearance of the moulded compound, yet their adoption reduces weight by up to 12 per cent per part and significantly improves scratch resistance to meet industry standards.

“The new grades will also offer a lower density than is currently provided, while still delivering up to 60 per cent recycled PP. The result of all this is that tier 1 moulding suppliers will be able to produce more parts per tonne of the mineral as they will benefit from a much faster cycle time. This will offset the slightly higher price these new advanced grades will require.”

Luxus is preparing a patent application for the new advanced polymer technology process. Its capacity however, to produce these compounds will be limited by access to local sources of recyclate PP. So in the future it intends to license its IP of formulations and knowledge to other selected compounders in the EU who have access source assured PP recyclate locally.
