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.

German tyre manufacturer Continental is set to showcase its new range of solutions for sustainable port operations at this year's TOC Europe.

Under the banner ‘Smart Port – Better Flow,’ the company is showcasing its tyre and digital technologies designed to enhance efficiency, safety and environmental responsibility in port logistics.

Federico Jimenez, Head of the Port Operation Tires Business Field at Continental, said, "We focus on the needs of our customers and provide them with tailor-made solutions. With our port tyres, we are already enabling more efficient, digital and sustainable operations – and are thus helping to shape the future."

Sustainability is a cornerstone of Continental Tires’ Vision 2030, aiming for carbon-neutral production by 2040 and a target of 100 percent sustainable materials in all tyres by 2050. This dedication was recently recognised with Continental's plant in Lousado, Portugal, receiving an award for environmentally friendly tyre production and Continental being named Tire Manufacturer of the Year at the Tire Technology International Awards.

A key product on display is the TerminalMaster, specifically developed for demanding port environments. Its extra-deep tread and reinforced industrial carcass offer high resistance to damage and extended mileage, contributing to more efficient, safe and sustainable operations.

Continental's holistic approach extends beyond robust tyres to a unique portfolio of digital solutions tailored for the port segment.

The order book for Curemaster is strong with a surge in orders during the first two months of the year. The executive anticipates continued momentum throughout the year, driven by increasing global demand for advanced, sustainable curing solutions.

FORWARD INTEGRATION

According to Rudman, digitalisation is playing a crucial role in enhancing the efficiency and reliability of curing presses. “Digitalisation provides real-time visibility into production processes, allowing manufacturers to monitor efficiency and product quality continuously. With a clear overview of operations, manufacturers can identify inefficiencies and ensure production targets are met. The HF XPLORE digital portal offers access to critical data at all times. It provides insights into machine health, predictive maintenance alerts and production performance. The system helps track efficiency, detect potential failures and optimise operations by identifying areas for improvement,” he said.

Artificial intelligence is also slated to play a key role in electrical heating, ensuring stable temperature control within the platens. Machine learning is being developed for predictive maintenance, helping to forecast bladder life and detect potential failures before they occur. These technologies are part of the company’s development roadmap, focusing on improving reliability and efficiency in curing press operations.

He also noted that as tyre compounds evolve, curing requirements will change, making electrical curing a more suitable solution. Unlike steam-based systems, where temperature is directly linked to pressure, electrical curing allows independent control of both factors. This flexibility is crucial for processing new materials that may not tolerate traditional curing conditions.

“In steam curing, the relationship between pressure and temperature is fixed. For example, achieving a temperature of 200 degrees Celsius requires increasing the pressure to 20 bar. With electrical curing, temperature and pressure are completely separate, enabling curing at lower temperatures while maintaining the necessary pressure levels. This capability is particularly significant for future materials, which may require curing at 160 degrees Celsius but at much higher pressures,” explained Rudman.

The shift towards electrical curing is expected to gain momentum, particularly for high-end and specialised tyres that demand more advanced curing strategies. While steam curing will continue to be used for lower-segment applications, the upper range of the market, especially where sustainability and material innovations are key factors, will require the precision and adaptability that electrical curing provides.

OVERLAPPING TECHNOLOGIES

There is a clear trend in the market where customers are seeking more customised solutions rather than standard off-the-shelf curing presses. Manufacturers now have unique requirements including features like electrical curing, digitalisation, automated loading and unloading and seamless integration with factory infrastructure and tyre transportation systems. As a result, the demand for tailored solutions is increasing, making flexibility a key factor in the adoption of new curing technologies.

“Curemaster is designed with upgradeability in mind, ensuring that tyre manufacturers do not have to replace entire presses when looking to modernise operations. Even older HF curing presses that have been in service for more than 20 years can be upgraded to electrical curing without altering the mechanical structure. This allows manufacturers to transition to more efficient curing technology while retaining the existing equipment. At the same time, the new Curemaster is available as a fully electric system from the outset, offering a ready-made solution for greenfield projects,” averred Rudman.

Nonetheless, the biggest business potential currently lies in retrofitting existing curing presses rather than selling entirely new equipment. “Many customers prefer upgrade kits that allow them to transition to electrical curing while maintaining current production setup. While greenfield projects present a significant opportunity for new fully electric presses, the greater demand at present is for retrofit solutions, as it provides a cost-effective way to improve efficiency and sustainability without major infrastructure changes,” he added.

PROCESS OVERVIEW

Most curing press suppliers have introduced electrical curing solutions. There are two main approaches to electrical heating, which are electromagnetic (induction) heating and resistive heating.

Electromagnetic heating method involves placing a coil outside the tyre to generate heat. However, there are concerns about how this method interacts with the tyre’s internal bead wire and breaker package. Since the long-term impact of electromagnetic fields on tyre integrity has not been fully tested or verified, there are still some uncertainties regarding its effects on tyre quality.

In contrast, resistive heating, which the company employs, places coils directly inside the plate, ensuring controlled and targeted heating. This method eliminates any risk associated with electromagnetic interference and allows precise temperature application only where needed. While both technologies are viable, resistive heating offers greater reliability and consistency in maintaining tyre quality.

“One of the key advantages of electrical curing is its rapid heating and cooling capabilities. The nitrogen used in the process can be heated from 20 degrees Celsius to 250 degrees Celsius in less than 20 seconds and cooled back down in the same time frame. This is achieved through continuous nitrogen circulation, where the system directs the flow through either the heater or the cooler as needed. In terms of curing time, electrical heating currently matches steam curing with a typical cycle of 10 minutes per tyre. However, there is significant potential to reduce curing time by 10 to 15 percent as electrical systems can operate at higher temperatures and offer more precise control over the process,” informed Rudman.

Nonetheless, steam curing has a predominant risk of mishaps in the bladder, which could lead to an explosion. The Curemaster is designed with a fully encapsulated dome, ensuring that any pressure build-up remains contained. If a failure occurs, the pressure is released downward instead of sideways, reducing the risk of injury.

The locking system is also unique. Even if there is a total power or hydraulic pressure loss, the press cannot open unintentionally. This containment and locking mechanism ensure a high level of safety during operation.

CHALLENGES AND OPPORTUNITIES

According to the executive, the biggest challenge in the curing press business comes from cost competition as lower-cost manufacturers pose a significant pricing challenge. However, from a technological standpoint, the company offers unique features that set it apart from competitors. While competitors may have cost advantages, HF’s focus on advanced technology, automation and digitalisation allows it to capture market share by offering superior functionality and efficiency.

The passenger car and truck segments remain the company’s primary focus owing to the highest growth potential. Additionally, the company sees an emerging opportunity in motorcycle and bicycle tyre curing, particularly with electric heating technology. HF is among the first to introduce electrical curing for these segments, positioning itself as an industry leader.

While HF is active in the passenger and truck segments, it has opted not to enter the off-the-road tyre market due to its relatively small size and intense competition. The segment still relies heavily on traditional mechanical presses, making it less attractive for innovation-driven solutions.

The company continues to refine the Curemaster lineup by introducing new materials, insulation techniques and design concepts. The company is particularly focused on increasing automation to enhance efficiency and reduce operational costs.

Beontag, one of the world’s largest manufacturers of self-adhesives and smart tags such as RFID, NFC and BLE, has entered into a collaboration with Kumho Tire to develop RFID-enabled tyres for commercial and passenger vehicles.

The partnership will see new Kumho tyres use Beontag's TyreTag RFID technology. Traceability will be possible with the RFID-enabled tyres from the point of origin to recycling and disposal.
