A big thumbs up for innovation!
Ottobock, a global market leader for med-tech products and fitting concepts specializing in prosthetics, orthotics and human mobility, is making its debut at HANNOVER MESSE with exhibits including the Paexo Thumb - the world's smallest exoskeleton.
Skeletons are supporting structures for organisms - either inside the body, as in humans, or on the outside, as in the case of insects and crustaceans. Biologists call the former endoskeletons and the latter exoskeletons. The idea of providing humans in need of assistance with an additional, outer skeleton has been around for some time. The concept originally focused primarily on medical requirements, but it gradually dawned on researchers that if an exoskeleton enables a paraplegic to walk upright, it could also help anyone at all handle heavy objects. Ottobock followed a similar thought process. For 100 years now, the global market leader specializing in prosthetics and orthotics has been developing med-tech products and fitting concepts for people with limited mobility. The MedicalCare division also provides patient care. To coincide with the company's centenary, Ottobock is exhibiting its industrial exoskeletons at HANNOVER MESSE 2019 for the first time.
Visitors to Hall 17 can test the Paexo range of passive exoskeletons and experience first hand how they relieve the strain on their bodies. "Exoskeletons designed for industrial settings will bring about permanent changes in many working environments. They can play a major role in preventing workplace injuries in many sectors, and help make workplaces more ergonomic. Based on our 100 years of biomechanical and orthopedic expertise, we are driving this change," says Dr. Sönke Rössing, Head of Ottobock Industrials.
As well as support devices for wrists and the shoulder area, Ottobock is also showcasing the new Paexo Thumb - currently the world's smallest exoskeleton. It is designed to help people who place strain on their thumbs at work on a daily basis. Clipping, inserting and plugging components on assembly lines can cause this kind of strain, for example. By redirecting the forces into the entire hand, the small and extremely lightweight exoskeleton is said to result in up to 70 percent less pressure being exerted on the thumb. What's more, users automatically assume an ergonomic hand position when wearing the Paexo Thumb. In addition to relieving the strain on thumb joints, it also protects the tip of the thumb from mechanical influences. The Paexo Thumb was developed and tested in collaboration with companies from the automotive and home appliance industries. The new device was tried out in paint shops and on assembly lines, for example. "The potential of the Paexo Thumb was clearly evident in these settings. It's a simple yet innovative solution for preventing joint problems in the hand," explains Rössing. The Paexo Thumb is one of the first Ottobock products to be fabricated in series production using a 3D printer. The exoskeleton "printed" in Germany is due to be available in seven different sizes shortly after HANNOVER MESSE 2019.

These are flanked by fully automated workpiece carrier- and robot-based assembly systems that offer solutions for customer-specific requirements. The company also supplies leak testing systems, modular assembly systems, pin placement systems and polishing machines for ceramic substrates. Over the past two years, ZELTWANGER has yet again invested heavily in its Tübingen site, with the production area of the mechanical engineering division alone growing by a good 8,200 square meters. All in all, the company believes it is well equipped for the future of mechanical engineering.
In fact, ZELTWANGER recently set up an ultra-modern machine park on its newly acquired production space, one that few companies in Germany can match. For example, the impressive, 50-metric-ton DMU 210 µPrecision 5-axis high-precision milling machine has just gotten a new sister. Standing peacefully side by side, the two gantry milling machines are not just an imposing sight, they are also brimming with cutting-edge technology: "Although our second DMU machine doesn't have a μ-precision option, it does have a precision package that delivers a position tolerance of 8 µm across the full working range. Moreover, it also machines workpieces weighing up to eight metric tons with maximum precision and dynamics," Andreas Wodarz, Managing Director of ZELTWANGER Maschinenbau, points out, adding: "Both large machines support 5-axis simultaneous machining in one clamping process. What makes all the difference is the ingenious, fully comprehensive cooling system that encompasses all the relevant machine components. This ensures temperatures are stable, which underpins maximum component precision." If Tübingen is a bit too far off the beaten track, then HANNOVER MESSE 2019 offers the perfect opportunity to check out the company's prowess.

They'll have you wrapped around their little finger!
Out to prove flexible displays aren't just for smartphones, the Leibniz Institute for New Materials (INM) is at HANNOVER MESSE 2019 to demonstrate additive printing processes for creating bendable touchscreens with enhanced material and cost efficiency.
Given that they either involve a string of process steps or large quantities of sometimes expensive raw materials, the standard processes for manufacturing flexible touchscreens are considered costly and laborious. Using photochemical metalization and printing (gravure printing, inkjet printing) of transparent conductive oxides (TCOs), the INM has therefore developed new processes that save a great deal of time and money. Visitors can discover the results for themselves at HANNOVER MESSE 2019.
"Most processes for conductor paths are subtractive. Metal is first applied over the entire surface and the excess metal is removed in further process steps," explains Peter W. de Oliveira, head of the InnovationCenter at the INM. "These classic processes, such as sputtering in a high vacuum and subsequent lithography, consume large amounts of silver. Our additive processes go the other way round, with conductor tracks being printed or deposited only where they are needed. Expensive high-vacuum technology isn’t required, which saves time and money," de Oliveira continues.
In another innovative printing process, the INM researchers use nanoparticle inks containing TCOs, such as indium tin oxide (ITO), for inkjet or gravure printing. "We use the TCOs to produce nanoparticles with special properties," says de Oliveira, adding: "The TCO ink is then produced by adding a solvent and a special binder. Not only does the binder ensure that the TCO nanoparticles adhere well to the film, it also increases the flexibility of the TCO coating - which ensures the conductivity is maintained when the films are bent. This makes it possible to produce highly flexible transparent conductor structures, for touch sensors or displays for example, in one simple printing process."

You can't miss it!
A gigantic hydraulic cylinder - which has been created to protect the east England town of Boston from North Sea flooding - is the unmissable highlight at the Hunger Hydraulik Group's stand at HANNOVER MESSE 2019.
As a global corporation specializing in the metal and capital goods industries, the Hunger Hydraulik Group is one of the world's leading suppliers of hydraulic solutions. Having accumulated more than 70 years of experience and impressive product, production and application know-how, Hunger skillfully combines hydraulic components to create bespoke modules and systems using state-of-the-art technology. As a result, customers receive end-to-end systems geared toward their specific needs that can satisfy stringent requirements even under tough conditions. For this year’s HANNOVER MESSE, the Hunger Group has chosen to show off something quite spectacular. Its gigantic hydraulic cylinder designed to act as a tidal barrier is sure to be an event highlight that make waves way beyond the Hunger Group’s stand.
Measuring twelve meters in length when retracted and weighing in at 44 metric tons, the cylinder on show is a real colossus with a diameter of 1.2 meters and pulling force of 950 metric tons, putting it in a class of its own. This gigantic structure was built for a tidal flood defense system in the port town of Boston located on the east coast of England. This project, dubbed the Boston Barrier, is designed to prevent North Sea tidal waves, which have caused the town to flood on multiple occasions, from reaching the city center via the local Haven and Witham rivers. The barrier comprises a 25-meter-wide gate that covers the entire width of the river and is entirely submerged when opened, meaning currents aren't obstructed and ships can pass with ease. The gate, which weighs an impressive 370 metric tons, is raised using two hydraulic cylinders manufactured by Hunger until the river is completely sealed off. Each hydraulic cylinder has a piston diameter of 860 millimeters and a piston rod diameter of 400 millimeters. Combined with a travel distance of 8,015 millimeters, this enables each of them to produce a maximum pulling power of 950 metric tons. The hydraulic cylinder on show in Hannover and its counterpart will be shipped to England and integrated into the tidal defense system in May this year. So the townspeople of Boston will soon be home and dry in preparation for the seasonal floods in the winter of 2019/20 and beyond.

LAPP's core market is the mechanical and plant engineering sector, with other key fields including foodstuffs, energy and Mobility. At HANNOVER MESSE 2019, LAPP is examining what the future of connection technology will look like and providing some clever and sometimes even surprising answers in its "futureLab".
Specially revamped for this year's event, the "futureLab" offers visitors a sneak peek into the solutions currently in the pipeline at LAPP. "With the new 'futureLab', we aim to cement our position as a technology leader," says Guido Ege, Head of Technology and Development at LAPP, adding: "The four focal points of the 'futureLab' are at different stages of market maturity. Some are already available and ready for the market, while others are currently in the functional prototype phase." A key focus is predictive maintenance, which offers a promising solution for preventing costly outages. Looking into this area, the experts at LAPP are exploring how companies can monitor the condition of their data cables and showcasing an innovative solution that no longer requires any changes to be made to the cable. Instead, an electronic device constantly monitors the signals transmitted by the cable and analyses their quality. If this falls below a critical value, the device issues an early warning, allowing the cables to be replaced during scheduled maintenance works. The electronic components required can be built into devices such as switches, which should minimize additional costs. And if LAPP cables already happen to be in use, as the device is configured to their electrical properties, it can simply be retrofitted to existing plants and machinery.

The outlook's looking good!
As a leading provider of IT solutions for manufacturing, MPDV is at HANNOVER MESSE 2019 to showcase a new application designed to predict product quality based on process data.
With over 40 years of hands-on experience, MPDV helps production companies as they strive to become smart factories. Thank to products such as the HYDRA manufacturing execution system (MES) and the manufacturing integration platform (MIP), MPDV helps companies make their production processes more efficient so they can stay one step ahead of the competition. According to MPDV, its smart software solutions are used every day by over 800,000 people in more than 1,250 production companies around the world. The company is at HANNOVER MESSE 2019 to showcase its latest solution, which uses executable models to make predictions.
MPDV works on the principle that the basic assumption when predicting quality is that wastage and reworking can still occur, even if all process parameters remain within the applicable tolerances. MPDV believes there are three steps to achieving predictive quality: (1) collect process data and correlate it with reliable quality data, (2) develop predictive models, and (3) execute the models and predict the quality based on real-time data. In addition to actually predicting quality (i.e. pass or fail), the system is also designed to determine the probability of each prediction. At HANNOVER MESSE 2019, MPDV is giving live demonstrations to show how this new predictive quality application works and the different ways it can be integrated into MES systems, such as HYDRA.

Taking printing into the next dimension!
Researchers from the University of Kaiserslautern are at HANNOVER MESSE 2019 to demonstrate how plastic parts for lightweight construction can be produced using 3D printers.
As keen readers of the HANNOVER MESSE portal will no doubt have noticed - 3D printers are becoming more and more important. After all, they offer a speedy means of manufacturing products. A team of researchers from the University of Kaiserslautern (TUK) looked into the conditions needed to achieve the best possible results when printing plastics. The composition of the material also plays a role here, and so, when producing their fiber-reinforced plastic, they used fibers that are completely integrated into the plastic like a string. The researchers believe this method could, for example, be useful for lightweight construction in the automotive industry.
"Our goal is to be able to manufacture plastic products using 3D printing in such a way that produces ideal results for the intended use," says Miaozi Huang, PhD student at the Institute for Composite Engineering, who is being supervised by Professor Alois Schlarb in the Department of Mechanical and Process Engineering. When producing their fiber-reinforced plastics, the TUK team uses "continuous fibers", which are integrated into the plastic as a whole - similar to a string. In other processes, these fibers are not added in one piece, but are instead mixed in as individual microparticles. The plastics produced with continuous fibers have a clear advantage, as the PhD student explains: "The continuous fibers make the finished product much more stable and rigid."

Cutting-edge – down to the very last fiber
The University of Applied Sciences and Arts (HAWK) in Göttingen is at HANNOVER MESSE 2019 to unveil a process that uses plasma treatment to make natural fibers more durable.
The new optimized plasma treatment process for natural fibers, developed under the leadership of Dr. Bernd Schieche and Martin Bellmann (M.Eng.), is designed to increase the service life of biohybrid fiber composites when exposed to fluctuating temperatures, humidity or UV radiation, for example. This new procedure is currently being developed as part of a European Regional Development Fund (ERDF) project for the state of Lower Saxony, which is being run at the Faculty of Natural Sciences and Technology at HAWK. The team of researchers is at HANNOVER MESSE 2019 to show that the materials they’ve developed are ideal for use in the automotive industry because, unlike plastics reinforced with carbon or glass fibers, their materials tend not to shatter when damaged, thus significantly increasing safety.
These biohybrid fiber composites, produced by combining natural fibers and conventional carbon fibers, are said to bring together the advantages of both fiber types in a way that best suits the intended purpose. However, until now, the inadequate durability of biohybrid fiber composites has made them unsuitable for use under critical climate conditions. Targeted plasma functionalization is set to change all that - by reportedly helping improve the properties of both the matrix polymers themselves and the fiber components, thus compensating for missing or inadequate material properties. According to HAWK, the aim of the current R&D project is to develop a cost-effective and environmentally friendly fabric and matrix treatment process that can be integrated into existing process chains and will significantly improve the material's service life and mechanical properties. By treating biohybrid fiber composites with plasma, the research team is looking to achieve a homogeneous fiber surface, which will help reduce or prevent air pockets and thereby dramatically lower the number of flaws that occur. It is anticipated this will ultimately have a significant impact on the materials' service life.
