HF Group’s upcoming range of digital solutions will monitor several parameters in the curing process, like cycle times, movements of the machines etc. One of the exhibitors at the Tire Technology Expo, 2022 that was held in Hannover, Germany was HF Group. Dr Bernd Pape, Digital Solutions, HF Group, threw light on the company’s plans to develop a new product line that will enable its customers to digitally monitor tyre curing machines more effectively, the significance of sharing data and having trusted partnerships.

The global tyre industry is steering more towards digitisation to ensure precision and save production time. And in this effort, HF Group seems to be the frontrunner, banking on data warehousing to produce effective monitoring solutions for tyre curing.

“HF is known as a company constantly extending traditional machine solutions. However, we are very well aware of digitisation, and the solutions will change our previous way of doing business at a global level,” said Dr Bernd Pape, Digital Solutions, HF Group, while we interacted with him at the latest edition of the Tire Technology Expo held this year in Hannover, Germany.

“I joined HF last year in June to build up a new product segment. However, due to the pandemic, I had limited chances to visit customers or talk to potential partners for development, and this conference has been an optimum opportunity to perceive an overview of our industry,” Dr Pape mentioned while he talked about the expo.

Digital solutions
HF’s upcoming range of digital solutions will monitor several parameters in the curing process, like cycle times, movements of machines etc. It will then churn out the alarm messages of the machines and correlate them to identify discrepancies. The new-age solutions will monitor machine data at different stages and have communication modules that will share the data from the machine control software to the internet using IoT gateways.

Extra sensors will be placed on the machines to measure certain component parameters like pressure, temperature, energy consumption etc. Leveraging the combination of cycle time monitoring, alarm messages and specific measurements of the sensor technology, the data will be analysed to bring out in-depth information about the machines’ performance.

Answering whether the sensors are capable of identifying the problems, Dr Pape informed, “In order for them to work efficiently to identify problems, we need quite some data. And when we have that data, we can do two things – analyse that data and see if insights can be derived automatically, or work with experts to derive insights and then transfer the knowledge into the digital solutions. He further added, “The entire research and development process demands a lot of communication and learning together with pilot customers, too.”

It’s important to share data
Initially, HF plans to implement the solution in their own curing press and further develop solutions for other machines. “We may need cooperation from customers to better understand other machines or even the OEM of that specific machine. If you look into digital transformation, it’s all about partnership. And if you don’t share data, you will not be able to flourish. And so far, my gut has been that our industry still has room to improve. We can still learn from each other by sharing data. With every new machine, we will have a growing database and knowledge on how to improve production,” Dr Pape asserted.

Digital benefit
HF strives to keep the cycle time of a machine at a constant low level. The curing process for one tyre may take 14 minutes. With the solutions, it can be reduced by 10 to 20 seconds. This would add up for the customer to produce roughly between 500 and 1,500 tyres per press per year, informed Dr Pape. Moreover, the solutions will enhance machine availability by detecting warnings for errors or repair time.

Trusted partnerships
The new solutions will require huge amounts of data to effectively do its task, but protection of proprietary data is a major concern. Speaking in this context, Dr Pape cited, “Digital transformation is about partnership, and you need to share data. So, partnership is all about trust. You need an initial amount of trust to provide data. There is no way around that.”

“On the other hand, once you give me the data, it is on me to keep it carefully and not to share it,” he further averred and went on, “Because if I do not comply, then the alliance will be harmed. So, there is a great opportunity because we are a long-standing partner for the whole industry. Therefore, we have trusted partnerships and projects with a lot of customers.”

Explaining the timeline from implementation to resumption of services, the executive said, “Once we are up and running with this solution, we just need a couple of days to implement it. But for new machine types that have not been analysed before, a couple of weeks are needed. Once knowledge of the specific machine type, how to adjust the software and how to analyse and interpret the data is known, we can configure same machine types within days.”

Current monitoring landscape
According to the executive, currently technicians might face severe problems while monitoring the machines as the industry has witnessed a generation shift. Experienced technicians retire and new ones have to learn the entire process. With the automation of unloading and loading systems, which are getting more and more automated, there might be no operators available who can point out if the machines have any problems.

“If we get the data from the machine and analyse it, we can redirect technicians to the area that causes the problem, so that they are faster in remedying it. The data will also help us to predict problems in the near future,” Dr Pape pointed out.

Stepping into the Indian market
HF has expanded its footprint across the globe and wants to market its products worldwide. The company’s pilot customers are in the Americas, followed by Europe. It also plans to tap into the Asian market.

Speaking on its plans to enter India, Dr Pape cited, “The country has great companies and some of them might be interested in the solutions. For building up a new product segment in India, we have to know what kind of customers are interested. We will then start operations on a remote basis and develop further.”

Collaborations for the long term
HF Group has also collaborated with Possehl Analytics as its solutions partner, which will also allow it to build a network for digital solutions in the industry. On the reference side, HF refers them as their solutions partner, while Possehl Analytics refers HF as a good operations partner.

Change is the only constant
While the tyre industry itself isn’t one that changes every day, we know that digitisation will have a pivotal role in its growth, including the tyre curing process, making sure the final product is of high quality. At the same time, sharing data and making long-lasting partnerships will only make the process and final outcome more competent.

Hana Technologies, Inc. (Hana RFID), a global leader in the design and manufacturing of embeddable RFID tyre tags, has become the first RFID company to join the Circular Rubber Platform. This development aligns with Hana RFID’s mission to drive innovation in tyre traceability and reinforces the company’s long-standing commitment to sustainability and circularity in the tyre and rubber industry.

Hana RFID has been at the forefront of RFID-enabled tyre traceability since 2005, facilitating smooth tracking from cradle to grave and promoting circularity. Hana's RFID tyre tags, which are embedded during manufacturing, provide each tyre a distinct digital identity, facilitating complete lifetime tracking from manufacture and use to recycling and reuse. Hana hopes to promote RFID usage in sustainable tyre lifecycle management by working with leading companies in the sector, which will eventually save waste and increase resource efficiency.

Using radio frequency identification (RFID) technology, an RFID tyre tag is a tiny, embedded device that tracks, monitors and controls tyres. In addition to providing smooth connection with inventory monitoring, fleet management systems and other digital applications, such as the European Digital Product Passport (DPP), these tags produce digital twins of tyres. Hana's RFID solutions empower the whole tyre ecosystem to expedite fleet management, improve inventory control, optimize maintenance, and create creative business models that increase sustainability and efficiency.

Val Peters, VP – Marketing, Hana RFID, said, “We are excited to join the Circular Rubber Platform as the first RFID company in this initiative.

We are therefore very happy to announce Hana as a new member of the Circular Rubber Platform, with the technology and experience they can provide to the platform. We look forward to sharing knowledge on RFID and working out opportunities for this technology in rubber industries that require Digital Product Passports in the near future, such as footwear.”

TÜV SÜD has expanded its test laboratory in Frankfurt am Main and unveiled new testing facilities at an Open Lab Day at the site, giving customers and employees an exclusive insight into the new state-of-the-art testing environments. The expansion strengthens TÜV SÜD’s position as a leading provider of independent testing and certification services.

Car charging plugs can now be tested in the lab to assess features like weather resistance, mechanical strength and electrical safety. To guarantee the endurance and durability of charging plugs and other parts, the new lab can also conduct crash testing on them. The inclusion of performance testing for tiny batteries is another significant development. Basic functional analysis will be the main emphasis of these tests at first, but in the second part of the year, comprehensive safety and performance evaluations will be included. Similar to this, power tool testing capabilities have been greatly increased to give manufacturers an even more thorough evaluation of the calibre, robustness and safety of their goods.

The capability to ascertain the biogenic carbon content of materials is an additional highlight of the expansion. These assessments support the implementation of sustainable manufacturing methods by giving businesses evidence of the utilisation of renewable raw resources. In order to make sure that packaging and other materials fulfil the strictest safety regulations and don't leak dangerous compounds into food, the testing infrastructure for materials that come into contact with food has been increased at the same time. It's also important to note the recently added ability to evaluate welding fume filtration systems, which may undergo a thorough performance assessment and will soon be certified.

TÜV SÜD is now able to provide an even greater variety of chemical testing services to make sure that products satisfy the most recent regulatory standards thanks to the expansion of its Frankfurt laboratory. With standardised testing for compounds including PFOS, PFOA, C9-C14 PFCAs, and PFHxS, there is a special emphasis on PFAS analysis. Due to the laboratory's expansion, even more businesses may now make use of its extensive testing knowledge, which includes services related to durability testing, risk assessment and certification for a range of product categories.

Walter Reithmaier, CEO, TÜV SÜD Product Service GmbH, said, “By expanding our laboratory in Frankfurt, we are responding to growing demand for product testing and certification. Our new testing capacities will set new standards in safety, sustainability and performance. We look forward to supporting our customers with state-of-the-art testing technology and professional expertise.”

Chicago-based Koala Technologies (KTL), a leading automotive testing, measurement and evaluation tools provider, has launched Te.Sense Bloom – a breakthrough in non-destructive rapid tyre deflation testing. The company has introduced the base kits starting at USD 20,000.

The solution the company claims is fully compliant with FMVSS 110 and emerging EV stability test standards. The Te.Sense Bloom allows passenger vehicle manufacturers and tyre makers to cost-effectively reuse solutions, thereby optimising test programmes while reducing waste.

Currently, the rapid tyre deflation tests often rely on a vehicle being driven over special roadway cleats at defined speeds. This method sees tyres destructively punctured and destroyed by the cleats, and internal inflation pressure is quickly reduced to atmospheric pressure. At times, these tests aim to ensure that the tyres are safely seated on the wheels post rapid deflation, wile at times it is to evaluate vehicle stability in terms of tyre failure.

The company stated that this tests however require destroying multiple tyres, not only leading to waste but may also corrupt certain vehicle dynamics tests that call for a single, targeted tyre failure.

On the other hand, with Te.Sense Bloom, the industry can use non-destructive controlled, rapid deflation for the selected tyres. Using a controllable central air ejector valve with a volume and a flow capacity that simulates a sudden tyre press loss. While the method sounds simple and frugal, the innovation lies in relation with the turn-key nature of Te.Sense Bloom. Automotive testers and engineers get a repeatable set up method, easy in-car operation and simple connectivity with data acquisition systems. As part of its comprehensive supply to Te.Sense Bloom customers, KTL even offers a wheel setup service to simplify test preparations.

The other advantage of Te.Sense Bloom is that the tyre deflation event can be triggered from inside the vehicle or remotely that further expands test scenario possibilities. It can be used for testing tyre inflation pressures up to 100 PSI and speeds up to 140 kmph (87 mph). The real-time tyre inflation data at 100 Hz has a claimed data accuracy of +/-0.1 PSI.  

Kenneth Martin, Head of Tyre Testing at the Transportation Research Center, said, “We have significant experience with rapid tyre deflation tests, using all types of methods, and we’re looking forward to evaluating KTL’s Te.Sense Bloom, since it represents a turn-key, non-destructive solution. There’s definitely some baseline justification for test equipment like this because it fundamentally means consuming fewer tyres. But Te.Sense Bloom’s inherent connectivity opens some other doors also, since triggered and monitored rapid tyre deflations are becoming an area of interest for vehicle stability testing, especially in EV space.” 

The first U.S.-specification kit has been delivered to the Transportation Research Center in Ohio for initial evaluations.

Being compliant with EV stability testing standards the Te.Sense Bloom is already being used by OEMs globally such as Huawei AITO, SAIC Motor Corp and GAC Motor to conduct regulatory tests such as GB/T 38796-2020 (Performance Requirements and Test Methods of Automobile Blow-out Emergency Safety Device).

Mike Lee, Founder and President, KTL, added, “Koala Technologies is excited to introduce Te.Sense Bloom into new markets, beginning in 2025. Bloom has been widely adopted for vehicle development testing in China over the last several years, becoming a must-have tool for many OEMs and key suppliers. It’s one example, among many, of an excellent, trusted, useful automotive testing device that no one knows about outside China. A part of our mission at KTL is to shine a light on some of these exciting technologies that are currently available, but not widely known. Another part of our mission is to help customers achieve their goals more efficiently and at a lower cost. We look forward to the upcoming testing at the Transportation Research Center in Ohio, and we hope that Te.Sense Bloom proves to be a good fit for automotive development programmes in the U.S and beyond.”

Bridgestone Corporation has developed a new Tyre and Road Wear Particles (TRWP) vehicle collection method aimed at understanding the environmental impact of TRWP. The solution was also displayed at the Tire Technology Expo 2025, held in Hannover, Germany, from 4 to 6 March.

TRWP is made up of a blend of road pavement components and tread (tyre surface). In order to comprehend the particle size distribution, dispersion behaviour, and environmental impact – as well as to create effective collecting techniques – Bridgestone is actively engaged in a number of TRWP research projects. The company is dedicated to comprehending TRWP and lowering its generation through these initiatives.

Utilising the B-Mobility testing facility at the Bridgestone Innovation Park in Kodaira, Tokyo, the company has created a state-of-the-art technique that makes it possible to gather TRWP effectively. Bridgestone has used laser light scattering in conjunction with a high-speed camera to visualise the dispersion of particles like TRWP. Based on this, the company has developed a device that effectively catches TRWP and covers the whole tyre. Additionally, the technique made it possible to collect TRWP effectively in a state that removes the effects of exhaust pollutants and broken dust by employing autonomous driving and an electric car with regenerative braking.

Through the Tire Industry Project (TIP), which is part of the World Business Council for Sustainable Development (WBCSD), Bridgestone has been researching the physical and chemical properties of TRWP and their implications on the environment. In addition to the continuous co-creation and internal R&D cooperation, Bridgestone is speeding up its efforts to evaluate TRWP's environmental consequences by collecting it effectively and with a high recovery rate using its recently developed collection technology.
