LG Chem and Reifenhäuser Agree to Collaborate on Establishing Competitive MDO PE Films for Sustainable Packaging

• LG Chem and Reifenhäuser sign MOU to develop Machine Direction Oriented (MDO)-PE blown films and flat films for recyclable packaging
• Aiming to surpass the normal market by producing recyclable films at competitive cost in a stable process
• LG Chem and Reifenhäuser set new standards in downgauging for competitive production of MDO-PE films

South Korea’s leading global chemical company LG Chem and the extrusion machine manufacturer Reifenhäuser have signed a Memorandum of Understanding (MOU), confirming further extensive cooperation. The aim is to further develop and market competitive Machine Direction Oriented (MDO)-PE blown films and flat films for recyclable packaging. The partners are building on a successful track record: In May 2024, the companies had presented the world’s first MDO-PE film only 18 micrometers (μm), which had been produced on an EVO Ultra Stretch blown film line from Reifenhäuser with specially developed PE materials (Polyethylene).

Bernd Reifenhäuser, CEO of the Reifenhäuser Group, says: “The demand for flexible mono-material packaging is growing rapidly. But MDO-PE films must be stable and economical to produce in order to make the leap from a niche to a broad market. With LG Chem and Reifenhäuser, we have found the perfect match of raw material, extrusion technology and process know-how that will pave the way. For the first time, processors will be able to produce recyclable MDO-PE films at competitive production costs in a stable process that can be optimally further processed.”

Dr. Lee Choong Hoon, Vice President and Head of NCC/PO Business Unit at LG Chem, adds: “We are very pleased to have found an experienced technology partner in Reifenhäuser to successfully combine sustainability and profitability. Our combined technology has achieved unprecedented records in downgauging MDO-PE film – and that was just the beginning. We will continue this path together to accelerate the recyclability for flexible packaging.”

Further downgauging for competitiveness

With perfectly coordinated system technology and formulation, processors will in future receive a tried and tested, complete package for immediate market access in the field of flexible mono-PE packaging. LG Chem and Reifenhäuser are also working on further reducing material consumption by downgauging towards the level of conventional PET-PE laminates and thus making the production of MDO-PE films more profitable. Technically, this isachieved due to the different densities of PET film and MDO-PE film by replacing the standard 12 μm PET film with a 16 to 17 μm MDO-PE film. With the reduction to 18 μm, the partners are already very close to achieving this goal. However, the experts see further potential: “The downgauging limit has not yet been reached,” says Christoph Lettowsky, Technical Sales Manager at Reifenhäuser Blown Film. “Thanks to the patented position of our MDO Ultra Stretch unit directly in the line’s haul-off, the film is stretched from the first heat. This makes the process particularly stable, which is otherwise often the limiting factor for material reduction. We therefore see even more scope, which we will use in combination with further recipe developments for even thinner films in the future.”

The 18 μm MDO PE film without PFAS additives was produced stably and reproducibly over many hours in test runs at the Reifenhäuser technical center and then printed and processed into finished pouches. The demand for PFAS-free materials is growing mainly in Europe as PFAS does not decompose in nature and has negative impacts on the environment. International guests were able to see the reliability of the process and the performance of the film for themselves at an open house on November 7.

Sauber Motorsport Optimizes the Post Processing of SLA Parts on Large Build Platforms with C1 Max

50 % faster, improved surface quality, and more environmentally friendly

Since February, Sauber Motorsport has been using a C1 Max from AM Solutions – 3D post processing technology for the post processing of SLA printed parts on their 3D Systems ProX 800 machines. The C1 Max is also compatible with the newer SLA 750 series. The system was developed as part of the existing technology partnership between the two companies and excels in many areas, particularly in terms of efficiency, surface quality, user-friendliness, environmental compatibility, and health protection.

The parts that Sauber Motorsport produces with SLA printing are highly complex and require maximum precision. This is evident from their application, as they are almost exclusively used in the wind tunnel for Formula 1 and are crucial for a vehicle’s aerodynamics. To consistently and quickly deliver high-quality 3D printed parts – approximately 1,000 parts per week between October and February – efficient post- processing is essential. “In the past, we had to manually perform many steps in the chemical post processing of SLA parts,”explains Vitor Sousa, Head of AM Plastic & CNC for AM at Sauber Motorsport.”This not only took a lot of time, especially with seven printers, but it was also a significant strain on the staff working with the solvents. Since February, we have been using two C1 Max machines from AM Solutions and are extremely satisfied.”

50 percent time savings with significantly improved surface quality

The C1 Max is based on the C1 concept and was specifically adapted by AM Solutions – 3D post processing technology to meet the needs of Sauber Motorsport for using large build platforms. SLA-printed parts are immersed in the treatment tank using an automatically lowering build plate and are surrounded by a specially temperature- controlled process fluid. A propeller, working in tandem with perfectly coordinated but individually controllable nozzles, ensures optimal flow around the parts and maximum flexibility. A mesh basket also ensures that no parts are lost or damaged in the immersion tank. The perfectly coordinated interaction of chemical, thermal, and mechanical processes softens the support structures, allowing them to be easily and gently removed. In the past, each part had to be laboriously processed by hand with a spatula, requiring extended PPE equipment. “This saves us a lot of time. We used to need an entire day to post process the output of our seven machines. Now, half a day is enough,”explains Sousa. ” Scrap is also minimized, and the surface quality is significantly higher, requiring much less effort in further post processing.”

More environmentally friendly process fluid and improved health protection

The C1 Max uses a specially developed process fluid from AM Solutions – 3D post- processing technology that is more environmentally friendly than conventional fluids. This also has a positive effect on the health of the staff, who can now work in the room without wearing masks.”The health protection of our employees was a very important argument for us,”Sousa emphasizes. Another practical advantage is that no additional equipment is needed when emptying the system. Once the medium is saturated, it is safely pumped out via the integrated pump and disposed of by a service provider. Overall, the cleaning effort for the system has been significantly reduced compared to before.

Future-oriented customer solution specifically developed for large build platforms

The development process of the C1 Max spanned about a year and a half, during which data and parts were continuously exchanged. An important aspect was determining the optimal size of the system. This allows the processing of a build volume of 750 mm (length) x 750 mm (width) x 550 mm (height) and thus the processing of a complete build plate of the 3D Systems ProX 800 or the SLA 750. Another advantage is that the "bare" plates can be easily placed in the system overnight for cleaning. "We used to have to laboriously dry-ice blast around 25 plates every Friday. Now, we can repurpose the space and time for other tasks," Sousa explains. To be prepared for future printer versions, adapters were used to make the machine flexible and adjustable to future needs.

“Formula 1 is the pinnacle of motorsport, which means we operate at the highest technical level. Safe and efficient processes are crucial for us, and with the C1 Max, we’ve taken another big step in that direction,” Sousa concludes.

VERTICAL INTERGRATION DRIVES SUCCESS IN TOLERANCE ATTAINMENT FOR MICRO MOLDING

Brett Saddoris, Technical Marketing Manager, Accumold

Achieving tight tolerances in micro molding is a complex process that requires carefulattention to every stage of production, from design through to assembly. The precision required for micro molded components, often used in industries such as medical devices, electronics, and micro-mechanical systems, demands a level of control that extends far beyond traditional manufacturing techniques. Tolerances, measured in micrometers, are crucial for ensuring the functionality, performance, and quality of these components.Success in this field relies on expertise in several key areas: design, material selection, the molding process itself, tool making, validation and metrology, and automated assembly. Moreover, vertical integration, where a single company controls all stages of production, offers a significant advantage in maintaining tight tolerances.

DESIGN ISSUES

The journey toward precision in micro molding begins with the design phase. Micro molding demands a unique approach to design, as the limitations and capabilities of the process must be considered from the outset. Traditional design principles cannot always be directly applied to micro molding, which necessitates specific adjustments to ensure the manufacturability of the part without compromising on precision. For example, plastic materials shrink as they cool, and this shrinkage can vary based on the polymer type and part geometry. In micro molding, even a minute variation in shrinkage can lead to significant deviations in tolerance. Therefore, accurate modeling and compensation for shrinkage are critical during the design phase.

Another challenge lies in maintaining consistent wall thickness, which is essential for achieving dimensional stability. Variations in wall thickness can cause non-uniform cooling, leading to inconsistent shrinkage and resulting in tolerance issues. The intricate nature of micro-molded parts, which often include features such as micro-channels or fine ribs, also requires precise attention during design. Even tight radii must be crafted with care to ensure that the mold can replicate these features without introducing dimensional inaccuracies. Draft angles, used to facilitate part ejection from the mold, must be carefully calculated to avoid warping, while avoiding complex undercuts can help reduce the likelihood of tolerance issues during the molding process.

MATERIALS

The material chosen for micro molding plays a pivotal role in ensuring that the final part meets the desired tolerances. Different polymers exhibit varying degrees of shrinkage, flow characteristics, and mechanical properties, all of which impact the ability to achieve precision. High-performance thermoplastics like PEEK and liquid crystal polymers (LCP) are often preferred for their superior dimensional stability. The ability of these materials to maintain their dimensions under stress and during temperature fluctuations makes them ideal for micro-molded parts where tolerances are crucial.

Material flow is another important factor to consider. In micro molding, the plastic must flow into very small, often complex mold cavities. Materials with high flowability are essential to ensure that every detail of the mold cavity is filled, preventing defects such as short shots or incomplete features. Additives like glass or carbon fibers may also be incorporated to enhance material strength or thermal properties, though these can also affect flow and shrinkage behavior. A thorough understanding of the material’s characteristics is crucial, and this is where vertical integration proves beneficial. In-house material science expertise allows for tailored material selection and optimization that aligns with both the design and the specific requirements of the micro molding process.

MOLDING

The molding process itself presents its own set of challenges in maintaining tight tolerances. Achieving the necessary precision in micro molding requires specialized machinery capable of controlling parameters such as injection speed, pressure, and temperature with extreme accuracy. Small deviations in these parameters can result in significant changes in part dimensions. For instance, if injection speed is too high or too low, it can affect how the material fills the mold, potentially leading to defects that affect tolerance. Similarly, maintaining consistent temperatures throughout the process is critical to avoid issues such as warping, shrinkage, or other dimensional inaccuracies.

Optimizing cycle time is also important in the micro molding process. While shorter cycle times are often pursued for efficiency, in micro molding, cooling time is particularly important to ensure that the part cools evenly and maintains its shape. Too short a cycle time can lead to parts being ejected from the mold before they have fully cooled, resulting in warping or dimensional inaccuracies.

TOOLING

Tool making, or mold fabrication, is another critical factor in achieving precise tolerances. The mold itself must be manufactured to extremely tight tolerances because even the smallest deviation can result in an out-of-spec part. Micro molds often have intricate features, and maintaining consistency across all cavities within a multi-cavity mold is crucial for uniform part production. High-precision machining techniques such as electrical discharge machining (EDM) and CNC milling are used to create the intricate details required for micro molds. Cooling channels within the mold must also be carefully designed to ensure even temperature distribution, as uneven cooling can lead to shrinkage issues that impact tolerances.

Vertical integration again proves advantageous in the context of tool making. A vertically integrated micro molder with in-house tooling capabilities can maintain tighter control over the mold-making process, ensuring that the tool is optimized for both the design and material requirements. This approach minimizes the risk of errors and ensures that the mold is capable of producing parts with the desired tolerances.

VALIDATION

Once the parts are produced, validation and metrology play a crucial role in ensuring that they meet the required specifications. Advanced metrology techniques are needed to accurately measure micro-molded components, given their small size and intricate features. Traditional measurement tools are often insufficient for this task. Coordinate measuring  machines (CMMs) and optical inspection systems are commonly used to verify the dimensions of micro parts with high precision. Micro computed tomography (Micro-CT) is another tool that allows for both external and internal features to be measured without damaging the part, which is especially useful for components with complex geometries.

The ability to validate part dimensions with precision is a key part of the micro molding process, and a vertically integrated molder will typically have dedicated metrology departments equipped with cutting-edge technology. This in-house capability allows for continuous quality control throughout the production process, identifying potential issues early and ensuring that parts remain within tolerance from the first to the last batch.

ASSEMBLY

For many micro-molded parts, tight tolerances must be maintained not only through the molding process but also during assembly, where these components are integrated into larger systems. Automated assembly processes are often necessary to ensure that these delicate parts are handled with the required precision. Human error in assembly can introduce variability that affects tolerances, making automation an important aspect of maintaining consistency. Automated systems equipped with vision-guided robots or alignment tools can handle the delicate nature of micro parts, ensuring that they are placed and aligned correctly during the assembly process.

In this regard, vertical integration once again plays a key role. A micro molder with in-house automated assembly capabilities can streamline the process, ensuring that tolerances are maintained from the initial molding stage through to final assembly. This end-to-end control  is a significant advantage when dealing with micro-molded parts, where even minor deviations can lead to significant issues in performance and functionality.

One-stop solution for data-driven decisions

When it comes to high-performance extrusion lines, SML is one of the technological leaders and has been in the market for extrusion machines for more than 25 years.  When developing digital services for its lines, SML adheres to the same “all in-house”-approach which applies to all of its other core competencies.

“For several years now “industry 4.0” has been a popular buzzword but the underlying question is always how the companies that operate our machines can benefit from the rapid developments being accomplished in the digital sector,” Christoph Strasser, Team Leader of SML’s Digital Business Unit, says. Like all of its other core competencies, such as mechanical engineering, electrical design or automation, SML makes sure to keep the development of digital solutions strictly in-house. Close co-operation among the different departments, all located at SML’s headquarters, supports the creation of coherent extrusion concepts with perfectly harmonised digital solutions.

bitWise: Analysing data – increasing productivity

Bitwise, the data generation and analysis tool, is at the heart of SML’s digital activities. Today it is used in more than 200 extrusion lines around the world. “bitWise enables the comprehensive collection, processing, analysis and transmission of manufacturing data – in an extraordinarily fast and easy manner. The process knowledge bitWise generates, helps to continuously optimise both the manufacturing processes and the product quality,” Christoph Strasser continues. Its main purposes are to streamline workflows, identify and solve problems pertaining to quality, analyse machine defects – and, above all, to increase machine productivity.

 The most popular areas of application include

• The real-time monitoring of various process-relevant or quality-relevant production values, such as the melt temperature, extruder pressure or coating weight – with an alarm function, if certain values deviate
• Digital shift books for the systematic documentation of all events during a shift
• The bitWise Track and Trace function: all of the data generated during production can be assigned to a specific, finished film roll, for example via a QR code. This presents new opportunities for quality control and product enhancement.

 Flexible dashboards for operators and CEOs

bitWise enables data-driven decision making, regardless of the organisational level – execution, planning or enterprise. It supports the machine operators, the maintenance team, shift leaders, quality managers and not least the CEO / management. To simplify day-to-day work, the bitWise dashboard can be customised to suit the specific field of activity of the user. Since bitWise is per se a web-based solution, remote access, i.e. via a tablet or a personal computer is possible, provided that the company can cater to the system requirements.

SML takes care of bitWise

bitWise was created by a highly skilled team of seven full-stack software developers and data scientists with a wealth of experience in automation and data analytics who now continue to develop it on a regular basis. The fact that bitWise is made 100% at SML generates an array of benefits. Above all, that SML takes care of it in a comprehensive way:

• Automatic updates from SML
• SML observes the components used and closes security issues
• SML monitors the local bitWise server attached to the extrusion lines, customers are notified by SML before problems occur.
• New features can be added automatically
• Personal support and assistance

 Open system – interconnectivity

One vital characteristic of bitWise is its system openness: The data exchange is based on open standards such as HTML and OPC-UA. So bitWise provides full interconnectivity for the comprehensive exchange of data between the extrusion line and connected machine auxiliaries, such as the inspection system, cloud-based solutions or the ERP.

50 Years of Rubik’s Cube: A Plastic Cube that Keeps the World in Suspense

From ABS plastic to recycled materials

U’ L’ ULUF U’ F’ – doesn’t mean anything to you? And yet you have probably already acted according to this pattern: when trying to solve the Rubik’s Cube. The plastic cube is celebrating its 50th anniversary this year. Originally made of wood, it is now of course made of plastic (some of it even recycled) and is as popular as on the first day.

From today’s perspective, it is difficult to imagine that the development of the small cube took six years. But where rapid prototyping, fused deposition modeling and the like make development easier for us today, in the past there was nothing. The cube had to be designed and built by hand. In 1974, the Hungarian Ernő Rubik developed the Rubik’s Cube, which has been world famous since the 1980s and bears his name. Rubik built the first models out of wood.

When the cube went into mass production, manufacturers switched to acrylonitrile butadiene styrene copolymer (ABS) and injection molding. After the black individual parts were produced and assembled, they were covered with the typical colorful stickers made of polypropylene film. The design is as simple as it is practical and the cube has never really gone out of fashion since the 1980s. The

cube was developed at a politically difficult time. While it became a bestseller in its native Hungary through word of mouth alone, distribution beyond the Iron Curtain was difficult. According to inventor Rubik (who was an architecture professor), it was simply too complex in the eyes of western companies. A toy that only a fraction of buyers would ever solve? Not interesting.

One company finally took the risk and estimated the sales figures (quite optimistically) at one million. Just off the mark: 30 million of the plastic cubes were sold worldwide in the first year. To date, the Rubik’s Cube has been sold almost 500 million times – about 52 times the current Hungarian population.

Today, the Rubik’s Cube brand belongs to the Spin Master company and is keeping up with the times when it comes to plastic. In addition to the many cube variants made of conventional plastic, Spin Master has developed the Rubik’s Re-Cube from 100 percent recycled plastic, taking a big step towards sustainability in the plastics industry. It is made of 100 percent recycled plastic. But that’s not all in terms of sustainability: in 2021, Spin Master Corp. in the USA teamed up with the company TerraCycle to make the cubes more recyclable. If the cube is no longer wanted, it can be sent to TerraCycle. There it is melted down and then processed into park benches, for example.

So what is the cryptic combination “U’ L’ ULUF U’ F'” all about? It’s simple: Cubers use letter combinations like this to note down their movements. The letters stand for the side of the cube that is to be moved (U for Up, L for Left, F for Front, etc.). An apostrophe is added when the side is turned anti-clockwise. Mathematicians have been racking their brains for decades over the shortest solution to the Rubik’s Cube, the so-called God’s number.

Have you got a taste for it? To ensure that users don’t despair after the first turn, there are numerous instructions on how to solve the cube. The official Rubik’s Cube website also provides a guide.

The God’s number describes the ideal solution to a mathematical problem. In the case of the Rubik’s Cube, this means solving the cube with as few turns as possible. The difficulty for the mathematicians lay in the number of possible combinations. There are 18 possibilities for the first move with the cube, then 18 more for the next move, and so on. This results in 43 trillion different positions. In 2010, the German mathematician Herbert Kociemba and the Californian computer scientist Thomas Rokicki proved that the God’s number is 20.

Aside from the recycled plastic, the Rubik’s Cube is also keeping up with the times in terms of digitalization. It is also available equipped with Bluetooth, so that an app can track every movement. But whether old school or modern: the Rubik’s Cube has fascinated people for decades. Incidentally, its inventor needed over a month to solve it the first time. So don’t worry if it takes a little longer.

The Rubik’s Cube in numbers

• Records : Max Park solves the 2023 cube in 3.13 seconds. A robot from Mitsubishi Electric Corporation needs only 0.305 seconds.
• Size : The largest Rubik’s Cube is 21×21 squares.
• Solution : There are 43 trillion ways to solve the Rubik’s Cube. This number of cubes could cover the earth 200 times.
• Documentary : In 2020, Netflix released the documentary “The Speed ​​Cubers”. Here, too, Max Park is one of the protagonists.
• Pop culture : The Rubik’s Cube also appears in films, for example in 2012 in “The Amazing Spiderman” with Andrew Garfield, in 1998 in “Armageddon” or in the animated children’s film “Wall-E”.

SABIC, a global leader in the chemicals industry, reports that B!POD, a business unit of SAES Getters, has selected SABIC’s OBP-based polypropylene resin as the material for their containers. In close collaboration, the partners selected SABIC  PP 576P, a high-gloss grade from the company’s TRUCIRCLE  portfolio of circular resins. The container material has an OBP feedstock content in the range of 50%.

Khaled Al-Jalawi, Global Director of Circular Economy Business at SABIC, states: “We are very pleased about working with SAES Getters to help consumers meet the challenge of improving food preservation with a powerful vacuum system that uses containers molded in OBP-based SABIC PP. The decision to replace standard virgin PP by our OBP material in the containers also marks a significant step towards greater sustainability, as it supports the transformation of the plastics economy towards circularity.”

The source of the OBP in SABIC’s material is abandoned used plastic collected in regions within 50 km of shorelines and then converted to plastic feedstock by means of advanced recycling. The PP resin produced with this recycle is supplied in natural color to C.E.L. (Costruzioni Elettromeccaniche Legnaghesi), a leading Italian player specializing in the processing of thermoplastic resins. C.E.L. adds special masterbatches to mold the B!POD containers in different sizes and several distinct custom colors. At the end of their service life, the reusable containers are fully recyclable in existing PP material streams.

Ginevra della Porta, Chief Innovation Officer at SAES Getters & co-founder of B!POD, comments: “This innovation embraces sustainability from the very concept to end use – with an advanced vacuum technology to minimize food waste, with SABIC’s OBP-based material that prevents used plastic from polluting our oceans, and with containers in a range of colors each dedicated to an endangered species, such as orangutan orange or whale grey, it is designed to raise the awareness of consumers. Moreover, our market research has indicated that reusable rigid containers for food preservation can  potentially eliminate the consumption of more than 300 non-recyclable plastic bags per person and year, which corresponds to a per capita release of 30 kg of CO 2 to the atmosphere.”

The selected OPB-based SABIC PP 576P resin is a food contact approved grade, free of PFAS and BPA. It offers ease of processing and delivers dimensionally stable parts with low warpage, good impact strength and high gloss as molded. The ocean-bound plastic based solution is fully certified under the International Sustainability & Carbon Certification (ISCC) PLUS chain of custody.

Allrounder 720 E Golden Electric:  Slim in design and price

• New: 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 new 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. Following its world premiere at NPE in Orlando, US, and its European premiere at Plastpol in Kielce, Poland, Arburg is now showing this machine for the first time at a trade fair in Germany at Fakuma 2024 (hall A3, stand 3101). It combines electrical precision, process stability and a small installation area with high component quality, 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 coupled with rising costs for labour, energy and materials as well as ever-shorter product life cycles and faster product changes. To enable attractive investment costs and a rapid return on investment (ROI), Arburg uses 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 so that the new Allrounder 720 E Golden Electric, with a width of just 1,848 millimetres, has a significantly reduced installation area compared to 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. Due to its smaller installation area, the new Allrounder fits into existing production grids and lines. 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 Arburg’s 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. The 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 easily accessible control cabinet concept as the new hybrid machines. A lubrication unit and an optional pneumatic system are located on the operating side. The parts chute in the machine base has been widened, making it easily accessible.

Flexible 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 relevant for almost every industry and of particular interest for technical injection moulding. Other 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, enabling a wide range of plastic parts to be produced flexibly, efficiently and reliably.

24 razor covers in 11.5 seconds

The new electric machine can also be automated with linear Multilift robotic systems and six-axis robots from Arburg. The exhibit is equipped with a Multilift V 30. At Fakuma 2024, the Allrounder 720 E Golden Electric with a clamping force of 2,800 kN and a size 800 injection unit will be producing PP razor covers by way of example. A 24-cavity mould from Hack will be used. The cycle time is around 11.5 seconds, with each moulded part weighing 1.2 grams. The 24 finished parts are then ejected in groups of four, clustered by cavity, into six boxes.

“Smart” communication for predictive maintenance

“Smart” communication between the production cell and its centrepiece, the injection mould, using OPC UA is essential for predictive maintenance. For this purpose, the “Moldlife Sense” computer system enables sensor-controlled mould monitoring over the complete life cycle and detects changes to the mould at an early stage. The measured values from various sensors on the mould can be visualised in the machine controller. If these are outside specified tolerances, an event is automatically generated. The same applies to the indicators for the built-in acoustic emission sensors, where the “noise ID” is visualised and checked to see whether it is within the given tolerances. Individual events, such as warnings, alerts and error messages, can also be displayed in the controller and documented. This allows users to identify anomalies in the process quickly and reliably and better assess what needs to be done. In an emergency, the machine stops and issues a corresponding message so that the operator can react correctly.
