Arburg: Electric Machine Technology

 Allrounder 720 E Golden Electric:  Slim In Design And Price

• Large: Electric Allrounder with 2,800 kN clamping force
• Attractive: Low investment costs, short delivery times, high level of flexibility
• Slimline: New design saves space and increases overall output

The Allrounder 720 E Golden Electric with a clamping force of 2,800 kN extends the product range of the electric series of the same name upwards. Its main advantages in a nutshell? A slim design with a price to match. The electric injection moulding machine launched on the market in 2024 is characterised by electrical precision and process stability as well as a small footprint and offers high component quality combined with low investment costs and short delivery times.

The extension of the electrical machine portfolio helps customers to meet current challenges such as increasing price pressure combined with rising costs for labour, energy and materials as well as shortening product life cycles and faster product changes. To enable attractive investment costs and a rapid return on investment (ROI), the company relies on standardised equipment without compromising on quality and performance. So the new “Golden” combines a high level of precision with a slimline design at a particularly attractive price/performance ratio.

Significantly smaller installation area

Arburg has optimised the design of the machine so that the new Allrounder 720 E Golden Electric, with a width of just 1,848 millimetres, has a significantly smaller installation area than other machines in its class. This has been achieved through features such as a new safety door with recessed handles. At the same time, the door opening has been widened to 1,400 millimetres, making the ejector area more accessible, for example.

The slim Allrounder fits into existing production grids and lines. Thanks to the new design, more machines can be set up in injection moulding production, resulting in an increased output per square metre. This is of particular interest when old machine technology needs to be replaced. However, even for new production facilities that are being planned, every achievable space saving is a valuable resource. Thanks to the slim design, more machines can be set up in injection moulding production, resulting in an increased output per square metre.

Reliable, stable machine technology

The Allrounder 720 E Golden Electric features high-quality machine technology to ensure stable and reliable plastic parts production. This includes a toggle-type clamping unit and direct drives from subsidiary AMKmotion. With an electric mould height adjustment system, mould installation heights of up to 800 millimetres are possible. The drive components are optimised for a clamping force of 2,800 kN. Proven, high-quality Arburg plasticising with the “aXw Control ScrewPilot” ensures reproducible injection and excellent moulded part quality.

Optimised mould venting with two-stage mould locking also plays a part in this. For convenient maintenance, the new electric Allrounder has the same control cabinet concept as the new hybrid machines. The lubrication unit and optional pneumatic system are easily accessible on the operating side. The parts chute in the machine base has been widened and is easily accessible.

Flexible in automation and application

The new electric machine is not limited to a specific product and is quickly available, which is particularly advantageous for short-term replacement purchases and capacity expansions. It is of interest to almost every industry and particularly suitable for technical injection moulding. Typical areas of application include dimensionally stable housings for electromobility, thick-walled closures for household goods, precision components for medical technology, and the construction and leisure industries.

The Allrounder 720 E Golden Electric is equipped with the Selogica ND control system as standard. If required, additional options and functions such as core pulls and heating and cooling circuits can be easily integrated and programmed. This means that a wide range of plastic parts can be produced flexibly, efficiently and reliably.

Furthermore, the new electric machine can be automated with linear Multilift robotic systems and six-axis robots from Arburg.

Interzero Revamps Leadership Structure

 The company has appointed a new CEO, CFO and CIO to head its entire business across Europe.

Interzero, a Berlin-based environmental service provider specializing in waste management, closed-loop solutions and plastics recycling, says it has established a single, groupwide corporate leadership team for all of Europe consisting of a chief executive officer (CEO), chief financial officer (CFO) and chief information officer (CIO). Jan Kroker has been named CEO, Yi Guo will serve as CFO and Claudia Wegener will serve as CIO. The company says advisory board member Peter Vogel is acting as interim CFO until Guo takes up his role.

Interzero says Kroker, Guo and Wegener are committed to continue bolstering the company’s positioning in a competition-oriented European market and further expand its role as an international extended producer responsibility (EPR) service provider.

“The circular economy should be more than just a national issue,” says Interzero Chairman and Owner Axel Schweitzer. “We are creating a consistent global positioning for Interzero to step up the internationalization of our company, deepen cross-border, interdepartmental collaboration along our value chain and strengthen our position as a leading international EPR system provider. The new groupwide leadership team will focus on pursuing Interzero’s vision of ‘a world without waste’ both strategically and operationally so that we can continue to work with our customers and partners to drive the circular economy.”

Going forward, the company says it also will focus on implementing sustainable closed-loop solutions as well as saving more materials from incineration and conserving resources via its role as an experienced plastics recycler. The company adds that digital solutions are increasingly vital to success when it comes to organizing efficient closed-loop solutions and has tasked Wegener with incorporating more digitalization into its corporate governance.

New leadership team

Kroker took over as Interzero’s CEO this month and previously was responsible for the company’s plastics recycling business. The company says he has a background in the chemicals industry and held senior management roles at KCA Deutag and BASF before joining Interzero.

Guo joins Interzero from the Alba Group Asia. After working for DZ Bank and HSH Nordbank (now Hamburg Commercial Bank AG), he moved to the Alba Group in early 2016. Most recently, he served as CFO of the Alba Group Asia with responsibility for strategy, finance and legal and has been part of the Interzero Holding management team since 2023.

Until Guo joins the management team, Interzero says Vogel will take responsibility for the group’s finances as interim CFO. Guo spent more than 10 years working for various auditing firms before moving to the Alba Group’s recycling business in 2010, where he served as CFO from 2017-2022. Vogel has been a member of Interzero’s advisory board since February 2023.

Wegener brings more than 10 years of expertise in IT and digital transformation processes, according to Interzero. She gained experience at companies including Deutsche Telekom before setting up and managing the Lizenzero online shop for packaging licensing from 2019 onward.

Sustainable Yogurt Pots: Rpet Makes It Possible

Together with machine manufacturer ENGEL, mould maker Brink, label maker iPB Printing and joint venture partner INTOPACK, ALPLA is realising thin-walled cups made from recycled PET material for dairy products for the first time. The innovative solution meets all the requirements of the PPWR and is set to go into series production from the 4th quarter of 2025.

Dairy products such as yogurt, cheese spreads, pudding, cream and curd cheese are to be packaged in a more environmentally friendly way in the EU in the future. The PPWR (Packaging and Packaging Waste Regulation) sets the direction. From 2030, plastic food packaging must contain a minimum percentage of recycled material – otherwise penalties may be imposed. The problem: cups for dairy products are made of PP (polypropylene) or PS (polystyrene) – and for both there is no approved recycling material from the mechanical recycling process for contact with food. Small quantities are only available through chemical recycling, which is far more costly and energy-intensive. Too little for widespread use.

ALPLA has the solution, and it is based on the all-rounder PET (polyethylene terephthalate). Together with machine manufacturer ENGEL, mould maker Brink, label maker iPB Printing and joint venture partner INTOPACK, the injection moulding division ALPLAinject has succeeded in producing thin-walled PET plastic cups with recycled material for the first time. rePETec stands for the interplay of innovative technology, mould, process and material treatment. For the first time, the single-stage injection moulding process allows for fully recyclable packaging made of up to 100 per cent rPET. For example, the 30 percent recycled material content required by the PPWR for PET is easily possible.

Established material cycle for PET

‘With rePETec, we create stable packaging with thin walls made of rPET, can recycle it after use and access the existing and established PET recycling stream. None of this has been feasible so far. With this solution, manufacturers of dairy products meet all legal requirements and at the same time strengthen the regional circular economy, ’ explains Thomas Maibohm, Head of Sales and Product Management Thin-wall Packaging at ALPLA. Following the successful test phase, ALPLA and INTOPACK are planning to start series production from the 4th quarter of 2025 – initially with the two standard formats of 180 and 300 millilitres. Others are to follow successively. Depending on the customer’s requirements, the filling volume can be from 100 to 500 millilitres.

Thin and tight

0.32 millimetres thin walls and integrated in-mould labeling (IML) minimize weight and material consumption. The higher specific weight of rPET is more than compensated by significantly better barrier properties. This increases the shelf life compared to conventional PP cups. ‘This opens up new opportunities for dairy products and can prevent food waste,’ says Thomas Maibohm.

The high-quality rPET is contributed  by system provider ALPLA from its own recycling plants in Europe – ALPLAinject meets ALPLArecycling.

‘Quality and availability are guaranteed in the long term,’ says Thomas Maibohm, emphasizing the benefits. After use, the PET yogurt pots can be included in the already established PET bottle cycle. The PP label is first removed from the packaging during mechanical recycling. ‘The cups enrich the ‘bottle-to-bottle’ cycle. In the future, a bottle can become a cup and then back into a bottle and so on. This saves resources, avoids waste and is financially unbeatable,’ Thomas Maibohm is convinced.

Nanoplastics Found To Disrupt Dopamine System And Social Adaptation

 Tiny plastic particles, or nanoplastics, could significantly alter brain development and behavior, according to a new study on mice published in Neuroscience. Researchers found that these particles affect the dopamine system – a key player in motivation and mood – and impact social behaviors during critical stages of development.

Nanoplastics, which measure less than 1,000 nanometers, are an emerging environmental concern. They are small enough to penetrate biological barriers and have been found in human organs, raising questions about their potential health effects. Earlier studies linked nanoplastics to inflammation and neurotoxicity in animals, but little was known about their impacts upon development.

To address this, Na-Hyun Kim and colleagues from Daegu Catholic University in South Korea examined how nanoplastics affected mice at different life stages. Using a carefully controlled study, the team administered nanoplastics orally once daily to pregnant mice during gestation, as well as directly to their offspring at different developmental stages.

The researchers divided male offspring mice into groups exposed to nanoplastics during mid-gestation, late-gestation, postnatal, juvenile, adolescent, or adult stages. They conducted behavioral tests such as locomotion, social behavior, and nest-building. Brain activity was also measured in regions tied to dopamine.

Upon analysis, the results revealed that the timing of exposure played a crucial role in determining its effects.

Social behaviors were notably altered, particularly in mice exposed during late gestation and early adulthood. These groups showed reduced social familiarity and increased anxiety-like behaviors, such as freezing when exposed to new environments.

Additionally, neural activity in key dopamine-related brain areas, such as the prefrontal cortex and amygdala, was disrupted.

Meanwhile, mice exposed during mid-gestation showed reduced movement, and those exposed during adolescence had heightened neural activity but no significant behavioral changes.

Evidently, the study highlighted differences in vulnerability based on developmental stages. “Overall… neural function influenced by nanoplastic administration influences the neurodevelopmental period from prenatal to postnatal, and their effects are different according to the timing of nanoplastic administration,” Kim and colleagues concluded.

While the study provides important insights, it also has limitations. It focused solely on male mice, leaving questions about potential sex differences unanswered. Additionally, maternal stress due to nanoplastic exposure was not evaluated, which could influence offspring development.

Despite these caveats, the research underscores the growing need to address nanoplastic pollution. With evidence mounting about their effects on the brain, these particles could have far-reaching implications for human health. For now, the study raises an urgent question: How can we reduce exposure to these invisible but impactful pollutants?

The study, “Effect of Nanoplastic Intake on the Dopamine System During the Development of Male Mice,” was authored by Na-Hyun Kim, Hye-In Choo, and Young-A Lee.
