Mold Sampling During Flow Simulation

Flow simulation data can significantly reduce the time until the real sampling of a tool, and avoid expensive tool modifications. The prerequisite is that the development partners work on the project in a centralised, simultaneous workflow instead of sequentially and contribute their know-how simultaneously. This is the result of a joint project in which Borealis, Oerlikon HRS flow and ENGEL used the example of a demanding mould to show how successfully injection moulding parameters can be optimised in the simulation and transferred directly to the machine as an initial setting proposal, provided that all relevant data of the injection moulding machine, the processed material as well as the hot runner system and other components are available. The experience gained from this close cooperation, the precision of the spot landing achieved with it and possible consequences for practice are presented by the partners in the context of a documentation that can be accessed online and will be presented at K2022.

The simulation was carried out with the aid of Moldflow , using the example of a family mould with three cavities and a weight difference of 1:11 from the smallest to the largest component. ENGEL provided a duo injection moulding machine, detailed values, for example on the geometries of the nozzle used, as well as the sim link data interface for the direct connection of Moldflow to the CC300 control unit of the injection moulding machine. Borealis provided the comprehensive, very precise data on the flow behaviour of the Daplen EE001AI polypropylene, and Oerlikon HRS flow contributed a servo-driven 8-cavity hot runner system that allows the volume flow to be controlled and thus each cavity to be filled individually.

In the traditional process, the parties involved do not discuss possible causes of faults and remedial measures until after sampling has been completed. In the project described here, optimisation with regard to temperature control, injection characteristics and all other pressure and time-related injection moulding parameters started jointly and immediately at the beginning of the simulation. The parameters determined in several iteration steps were then transferred to the machine via sim link. This data exchange between simulation software and injection moulding machine can take place in both directions. It thus also enables the analysis of process data, which in turn provides potential for process optimisation. Access to sensitive design data is not necessary.

The real production start-up underlined the high precision of the settings found via Moldflow . The real filling behaviour and the positioning of the weld lines matched the simulation 100 %. The warpage behaviour of the largest part, the door trim measuring around 600 mm x 400 mm, was predicted to within ±2 mm, and the dimensions across the diagonal of over 650 mm were maintained with maximum deviations of only 0.04 %. After a few optimisation steps and without major manual readjustment, all three moulded parts met the quality requirements.

This joint project has not only shown that real production has run almost identically to the simulation, but the result also opens up potential for more sustainable production. For example, it is possible to see in the design phase whether a machine is suitable for the intended product or whether energy can be saved and production efficiency increased by using a smaller machine. In addition, the setting data suggestion developed in the simulation reduces the number of necessary setting cycles. This leads to fewer rejects and lower energy consumption during sampling.

Markus Kralicek, Business Development Manager at Borealis, Michael Fischer, Head of Business Development Automotive Technologies at ENGEL, and Stephan Berz, Vice President Sales at Oerlikon HRSflow and General Manager DACH, will report on the project itself and many additional details in a free, off-line webinar at https://www.hrsflow.com/ww/en/events/borealis-engel-oerlikon-hrsflow-webinar. In addition, the speakers will present the results during K 2022 at the Oerlikon HRSflow stand (Hall 1, Stand D10) on Thursday, 20.10.2022 at 4.30 p.m. and on Tuesday, 25.10.2022 at 4.00 p.m.

Digitally Networked Production Cell Communicates With Mould and Periphery

An especially “smart” exhibit at the Arburg trade fair stand “13A13” and an example for the future of digital production cells is the turnkey system based on a hybrid Allrounder 630 H: the injection moulding machine communicates via the Gestica control system and OPC UA with mould, hot runner controller, material dryer and automation. The “Moldlife Sense” computer system is integrated into the 32-cavity mould provided by Arburg’s partner Hack, and enables monitoring across the complete life cycle.

In this example, the practical advantages of digitalisation and automation in plastic processing are especially evident in the production of blood vials for medical technology.

New interface: machine communicates with mould
The “Moldlife Sense” computer system enables the complete life cycle to be monitored. Arburg has implemented the new solution for communication between mould and machine together with the cooperation and development partner Hack. A hybrid “Packaging” Allrounder 630 H in clean-room design produces, with the 32-cavity mould of Hack, transparent blood vials made of shatterproof PET. The location of changes occurring at the mould can be precisely assigned with the help of a sensor system. Two cameras take images or videos, e.g. of mould separation and parts ejection. There are also four displacement as well as four knock sensors for the tie-bar guidance. In this way, process changes can be detected at an early stage and damage to the mould reliably avoided. The data is passed directly to the machine control system via an OPC UA interface.

The "Moldlife Sense" computer system enables the complete mould life cycle to be monitored. — The “Moldlife Sense” computer system enables the complete mould life cycle to be monitored.

Gestica features for quick and secure working
In addition to the mould, the central Gestica control system, hot runner controller (Mold Masters), a special PET material dryer (Eisbär) and the automation (Waldorf) are connected to the central Gestica control system via OPC-UA. In this way, the temperatures of hot runner and dryer can be monitored, and the automation started and stopped directly via the Gestica. The hot runner controllers also communicate via the Euromap (EM) 82.2, and the automation via the new interface EM 79. Further features such as the “aXw Control PressurePilot” controller function and the “aXw Control MeltAssist” provide additional process reliability and enable comfortable and quick working.

In-line quality assurance
32 blood vials are produced in a cycle time of around 7.5 seconds, and removed via a side-entry robot made by Waldorf. The encapsulated automation is equipped with four cameras, which check that the components are straight. A QA request can also be called up at the push of a button.

“Economically, Recycling is Perfectly Feasible”

“Economically, Recycling is Perfectly Feasible”

Interview with Jochen Hirdina, Head of Plastics Technology at Krones AG

Mr. Hirdina, Krones is pursuing its own sustainability strategy. What are the cornerstones?
Krones has set itself very ambitious climate targets for 2030. As a company, we will have reduced our carbon footprint by 80 percent by that time. For our products, we plan to reduce carbon emissions by 25 percent. We will also reduce hazardous waste and drinking water consumption by ten percent. Another important element in our sustainability strategy is to contribute our part towards a closed-loop recycling economy. We want to help avoid plastic in the form of waste. In the beverage industry, we are well on the way to completely closing the loop with PET bottles in Germany, and things are also moving in Europe. The reason for this is, that the European Union has made provisions for recyclates that are forcing our customers and the industry to take action. I’m witnessing a great deal of movement in that regard right now.

Could you give us an example?
First of all, you have to realise how the cycle works. Products are manufactured, which are then returned after use and reprocessed into a new product. Collection is of course the basic prerequisite for a cycle to function, but you also have to know what happens to the material, and where you’ll reuse it. The ideal scenario is to use it again in exactly for the same application it had originally. This works relatively well with short-lived products such as bottles, because there is a high turnover rate. In other areas, it will probably be much more difficult. A large discounter in Germany has started to build its own value chain for a closed loop. For me, this is a kind of blueprint for how the whole process can work.

If we look at the situation in Germany, a lot has happened in recent years. For instance, not all PET bottles were included in the cycle in Germany until now in the beverage sector. Bottles containing fruit juice for example were not included. This has now been standardised, and the bottle deposit now applies to the entire beverage range. We have collection rates of 98 percent for PET bottles, and it has been found that the collected PET quantities are actually used again to produce new PET bottles. So, Germany is already doing very well in terms of the closed cycle.

But when some big companies like Lidl do something like this, there will not be enough left for the many small ones.
That is indeed the reality of today. However, this is due to the fact that we still have too little recycling capacity available. It must of course increase so that the returns can be completely converted into new recyclate. Viewed globally, the current low capacity is a consequence of the lack of economic efficiency of recyclates to date. In recent years, it was simply cheaper to buy virgin material because of the low oil price. Meanwhile, we have very high energy prices, and the use of recyclates is regulated by law. Because of the price development and the increased demand, recycling can now be implemented economically. We will therefore see an expansion of recycling capacities in the years to come. Another factor of course is the raised awareness of sustainability in the industry. For example, a major US beverage company has announced that it will only use rPET for some of its products.

In addition to its core business of bottling plants, Krones also has recycling plants. How did that come about?
We have basically been involved in recycling for a very long time. We gained our first experience in the field in 2000, when we built the first PET recycling plant in Switzerland, together with another company. In addition, we have decades of experience in building cleaning machines for bottles. After all, every recycling plant needs cleaning machines to remove the label and product residues, for example. And we were aware early on that plastic recycling represents the future, so for this and a number of other reasons, we decided to enter the recycling sector in 2009.

We undertake complete project planning for recycling plants, which is a core competence for us as a plant manufacturer. We offer our own core modules for this purpose. MetaPure W, for example, is a washing module for plastics. And to bring plastics back to the desired product properties, we offer a system named MetaPure S. Our recycling business is very important for us, even if we are not the market leader in that sector, which we are for beverage systems. However, our recycling technology is very well received by our customers.

Does it make sense to link such recycling plants with an application, such as a beverage bottling plant?
In principle, it is of course possible to use the material from a recycling plant as a starting material for the production of new preforms. It is also possible to place the interface in a beverage plant and use the recyclate to make new bottles, however, it won’t be integrated into the process. The reason for this is easy to explain: ideally, a recycling plant will be operational for 365 days a year; that’s when it’s at its most efficient. In a beverage line on the other hand, there are fluctuations, because people drink more in summer than in winter, so more bottles are filled accordingly. During the summertime, the lines have to run around the clock, whereas in winter, you can skip a shift or two. One-to-one interlocking would not work and would not make sense economically, either.

How important is cross-company exchange in the circular economy?
This is indispensable in view of the complexity of the circular economy and the many industries involved in it. In the past, these different industries had few points of contact. If we want to get to grips with the common problem of plastic waste, exchange is essential. At present, there is still room for improvement. Everyone has to be open in their dealings with partners, otherwise it will be difficult to implement an end-to-end circular economy. Fifteen or twenty years ago, companies were still extremely secretive towards each other. Fortunately, this has improved, because, if we want to leave a liveable planet for future generations, we all have to pull and work together, and time is currently working against us.

Making Nanodiamonds Out of Bottle Plastic

Making Nanodiamonds Out of Bottle Plastic

What goes on inside planets like Neptune and Uranus? To find out, an international team headed by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the University of Rostockand France’s École Polytechnique conducted a novel experiment. They fired a laser at a thin film of simple PET plastic and investigated what happened using intensive laser flashes. One result was that the researchers were able to confirm their earlier thesis that it really does rain diamonds inside the ice giants at the periphery of our solar system. And another was that this method could establish a new way of producing nanodiamonds, which are needed, for example, for highly-sensitive quantum sensors.

The conditions in the interior of icy giant planets like Neptune and Uranus are extreme: temperatures reach several thousand degrees Celsius, and the pressure is millions of times greater than in the Earth’s atmosphere. Nonetheless, states like this can be simulated briefly in the lab: powerful laser flashes hit a film-like material sample, heat it up to 6,000 degrees Celsius for the blink of an eye and generate a shock wave that compresses the material for a few nanoseconds to a million times the atmospheric pressure. “Up to now, we used hydrocarbon films for these kinds of experiment,” explains Dominik Kraus, physicist at HZDR and professor at the University of Rostock. “And we discovered that this extreme pressure produced tiny diamonds, known as nanodiamonds.”

Using these films, however, it was only partially possible to simulate the interior of planets – because ice giants not only contain carbon and hydrogen but also vast amounts of oxygen. When searching for suitable film material, the group hit on an everyday substance: PET, the resin out of which ordinary plastic bottles are made. “PET has a good balance between carbon, hydrogen and oxygen to simulate the activity in ice planets,” Kraus explains. The team conducted its experiments at SLAC National Accelerator Laboratory in California, the location of the Linac Coherent Light Source (LCLS), a powerful, accelerator-based X-ray laser. They used it to analyze what happens when intensive laser flashes hit a PET film, employing two measurement methods at the same time: X-ray diffraction to determine whether nanodiamonds were produced and so-called small-angle scattering to see how quickly and how large the diamonds grew.

A big helper: oxygen
“The effect of the oxygen was to accelerate the splitting of the carbon and hydrogen and thus encourage the formation of nanodiamonds,” says Dominik Kraus, reporting on the results. “It meant the carbon atoms could combine more easily and form diamonds.” This further supports the assumption that it literally rains diamonds inside the ice giants. The findings are probably not just relevant to Uranus and Neptune but to innumerable other planets in our galaxy as well. While such ice giants used to be thought of as rarities, it now seems clear that they are probably the most common form of planet outside the solar system.

The team also encountered hints of another kind: In combination with the diamonds, water should be produced – but in an unusual variant. “So-called superionic water may have formed,” Kraus opines. “The oxygen atoms form a crystal lattice in which the hydrogen nuclei move around freely.” Because the nuclei are electrically charged, superionic water can conduct electric current and thus help to create the ice giants’ magnetic field. In their experiments, however, the research group was not yet able to unequivocally prove the existence of superionic water in the mixture with diamonds. This is planned to happen in close collaboration with the University of Rostock at the European XFEL in Hamburg, the world’s most powerful X-ray laser. There, HZDR heads the international user consortium HIBEF which offers ideal conditions for experiments of this kind.

Precision plant for nanodiamonds
In addition to this rather fundamental knowledge, the new experiment also opens up perspectives for a technical application: the tailored production of nanometer-sized diamonds, which are already included in abrasives and polishing agents. In the future, they are supposed to be used as highly-sensitive quantum sensors, medical contrast agents and efficient reaction accelerators, for splitting CO2 for example. “So far, diamonds of this kind have mainly been produced by detonating explosives,” Kraus explains. “With the help of laser flashes, they could be manufactured much more cleanly in the future.”

The scientists’ vision: A high-performance laser fires ten flashes per second at a PET film which is illuminated by the beam at intervals of a tenth of a second. The nanodiamonds thus created shoot out of the film and land in a collecting tank filled with water. There they are decelerated and can then be filtered and effectively harvested. The essential advantage of this method in contrast to production by explosives is that “the nanodiamonds could be custom cut with regard to size or even doping with other atoms,” Dominik Kraus emphasizes. “The X-ray laser means we have a lab tool that can precisely control the diamonds’ growth.”

Successful Trade Fair Premiere: Electric Compact Transporter Sevic V500e Impressed Journalists and Trade Visitors at IAA Transportation

IAA Transportation stand in Hall 13 showed application diversity and
scalability of the Sevic V500e.
High demand for test drives on the course in Hall 11.

“With seven vehicles on site and an exhibition stand of over 200 square metres, we presented what our compact vehicles are capable of at the IAA Transportation. After seven successful days, we are delighted about the wave of interest and inquiries we had. Especially the rightly very critical trade journalists were very interested in our solution for the last mile and we were able to convince them at close range of the high production quality Made in Europe. I am very proud of the entire team, which did a great job here in the planning and execution of this event,” says Sevic Managing Director Alexander Brilis.

For one week, Sevic staff answered questions about the vehicles from interested trade visitors, industry experts and journalists at stand A80 in hall 13, and the Sevic V500e could then be test-driven in hall 11. The charging process was demonstrated on the Plug & Play Campus. There was a choice of two vehicles for the test drive – a pickup and a box body.

The V500e is a compact L7e-CU class electric commercial vehicle, ideal for use in urban areas. The vehicle is built in Europe and consists mainly of parts of European origin. Sevic’s corporate headquarters are located in Bochum, Germany. Thanks to near- and reshoring, Sevic has access to a stable supply chain and an excellent spare parts supply.

During the development of the V500e, which can reach speeds of up to 80 km/h, great importance was attached to a wide range of applications and scalability. The patented cargo swap system, for example, ensures that the transport superstructures can be exchanged quickly. The loading and unloading process of the cargo boxes therefore does not have to be carried out on the stationary vehicle, but can take place where itis easiest for the user. This also ensures that the vehicle does not block narrow roads and additionally reduces downtimes.

In addition, users can choose between different superstructures. Variants include boxes with different options, such as sliding, rolling or folding doors. In addition, various flatbeds are available. All these superstructures are simply exchanged with a standard forklift truck if required. Within a few minutes, users can switch between currently six bodies – for example, from a sales box to a pick-up body. This makes the Sevic V500e suitable for a wide range of applications and thus particularly economical.

The V500e is also flexible in terms of range and purchase price: the standard battery size with 16.5 kilowatt hours (kWh) and up to 150 km range costs 24,900 € net (plus body and transfer); the long-range model with a 33-kWh battery and up to 300 km range (confirmed by TÜV Nord) is available for 29,500 € net plus body and transfer.

XSYS Introduces Enhanced Woodpecker Nevis Surface Screening

Expanding the Thermo Flexx Woodpecker family of high frequency surface screens, Nevis has been specifically developed for printing with white inks on film-based substrates.

XSYS is pleased to announce a new version of Thermo Flexx Woodpecker surface microstructure technology that enables higher imaging speeds of flat top dot flexographic plates for standard white inks. As a simple, open and effective screening solution, Woodpecker Nevis has the potential to save on costly white ink while providing more contrast and improved colors in flexible packaging printing. Already commercially available, it is the latest addition to the Woodpecker portfolio, which also includes the Sharp, Nano and Replay options for Thermo Flexx TFxx plate imagers.

“Woodpecker Nevis screening improves overall brilliance and makes it possible to save on white ink costs while also simplifying and speeding up the imaging process,” said Christophe Lievens, Global Sales Director XSYS Prepress. “In combination with the Thermo Flexx Multiplate option, which allows multiple resolutions to be imaged on the same plate, it delivers a more cost-effective and competitive solution that will help printers optimize OEE and reduce waste.”

The objective of the Woodpecker surface screening solution is to control the ink more accurately, as it is transferred from the anilox to the plate and onto the substrate. The result is a smoother, higher opacity ink laydown, sharper line work, and cleaner screens, without any of the common printing defects often found in flexo printing, such as pin holing, trail edge voids, and halo effects, at full press speed.

Woodpecker surface microstructures are applied at the imaging stage and is an adaptable solution that works with open RIPs. Furthermore, as the pattern is not embedded in the file, which normally increases its size greatly, much faster data exchange and computer processing times can be achieved. This significant reduction in workflow complexity also improves plate delivery times and ultimately speed to market for brand owners.

Developed to work seamlessly with the higher volume anilox rollers usually used for printing with standard white ink on film-based substrates in flexible packaging, Woodpecker Nevis consists of three surface patterns with different levels of coarseness for the broadest application reach. While a higher volume anilox will increase quality and opacity, there is also the option to decrease the anilox volume which may consume less expensive white ink without negatively impacting the opacity.

“Good coverage of white is essential in flexible packaging printing where it provides the foundation for strong colors and impactful graphics. However, white ink can represent as much as 50% of the total ink costs, so XSYS continues to develop new products that can help optimize the process, lower costs, andtake out more waste. With Woodpecker Nevis, we are bringing to market a flexible and sustainable solution that can be adapted to each customer’s individual needs,” concluded Stephan Reis, Global Marketing Director. “We now offer high frequency surface screens for process colors and white, thereby covering the whole spectrum.”

Making Music With TPEs

TPEs that are suitable to be applied on musical instruments and accessories. With features such as soft touch, scratch resistance, wide hardness range and more, TPEs are widely being used as solutions to musical instruments and accessories.

Music serves not only to provide entertainment to individuals but also to sooth frayed nerves, in some instances. Music has been known to help relieve stress and even been proven to control our heart rates and blood pressure.

Creating music and playing musical instruments are tangible forces that have the power to magnify and enhance emotions and it is for these reasons music is known as “food for the soul”.

Meanwhile, musical instruments and accessories need to be able to stand the test of time and rigors of handling and constant use. Previously, materials like wood and metals were used in musical instruments, and now manufacturers are utilizing state-of-the-art materials, such as thermoplastic elastomers (TPEs), in their products to allow for more convenience, ease of use and lighter weight.

Kraiburg TPE, a global TPE manufacturer of a wide range of thermoplastic elastomer products and custom solutions for multiple industries, offers TPEs that are suitable to be applied on musical instruments and accessories. With features such as soft touch, scratch resistance, wide hardness range and more, TPEs are widely being used as solutions to musical instruments and accessories.

TPEs: music to the ears
Kraiburg TPE’s compounds offer excellent resistance to sebum and oil and, thus, are suitable for applications such as earphones, headsets, and earpiece tips that are in constant contact with the human body.

With the soft touch feature of Kraiburg TPE compounds, comfort is also maximized, especially in wearable electronic devices.

TPE compounds can also be used for sound damping of musical equipment. The sound absorption effect of the compounds provides stability and noise reduction on equipment such as speakers, amplifiers, and record players.

Providing versatility in musical equipment
KRAIBURG TPE’s compounds are known for their high abrasion resistance, allowing for suitability in musical instrument accessories such as foot pedals, protection pads and portable keyboard stands.

The scratch and wear/tear resistance features of TPEs also make the compounds suitable to be used on musical accessories such as buttons, seals and switches on digital tuners and metronomes.

Kraiburg TPE offers non-toxic, environmentally-friendly materials with a wide hardness range, which allows a multitude of musical instrument applications.

Furthermore, the TPEs can be pre-colored into various color options that creates more inspiring designs for applications in the music sector.
