Emerson, a global automation solution supplier, is known for its solutions that help tyre manufacturers to have efficiency, safety and precise operations in five production areas- mixing equipment, wire and fabric calendars, extruders, tyre building machines, curing presses and finishing process.

Currently, the company is focusing more on solutions for the tyre curing process, which consumes the greatest amount of energy during the tyre production. If tyre curing process does not work correctly, it could also lead to tyre scrap and even breakdown.

“Today, we are focusing on increasing our value as a solution provider to monitor the health and performance of the curing system. Within the curing process, we are not just supplying valves or components, but we also deliver the controller, pneumatic valves and sensors that monitor each step of the process,” said Chris Bart, Director Business Development Automotive & Tire at ‎Emerson Automation Solutions.

According to Bart, the challenge in the tyre curing process is to have precise control on temperature and pressure. With Emerson’s technologies, tyre manufacturers can maximise output and reduce energy and costs through better diagnostics, sensing and monitoring.

 “The main challenge is the management of steam and nitrogen used to heat the mould and bladder pressure.  So, any small deviation in the inputs can have severe negative effects on the quality of the products and overall productivity of the production line or the plant,” explained Bart.

In the tyre curing process, Emerson’s pressure-operated valves work in demanding steam applications and provide reliable and precise control, enabling rapid cycling and tight shut-off to ensure the curing press operates correctly and efficiently.

“Emerson’s valves system controls the movement of the steam and nitrogen into the process. Our valves are critical to supply steam and nitrogen in the proper time with proper temperature and pressure and make sure that there is no leakage during the cycle or between cycles,” explained Bart.

Digitisation helps Emerson’s steam valves to monitor the travelling time of the steam valve and detect anomalies, which ultimately assist in a predictive maintenance programme. “If any deviation happens, the system alerts the maintenance team, and downtime could be avoided,” said Bart.

Traditionally tyre manufacturing companies put a temperature gauge and a pressure gauge to monitor temperature and pressure in the piping system. “Earlier, it was tough to point out the reason for the deviation in temperature and pressure.  We have developed our products that control the steam and nitrogen and also included the sensors that tell the exact position of the valves. So, we can also monitor the leakage of nitrogen, steam and the air we use in operation. It also monitors the air pressure that opens and closes the steam valves. We can monitor the total consumption of the compressed air as well,” said Bart.

“Today’s typical approach to see the only results, but with our system, we are giving is infinite detailed inside the system. This gives customers actionable insights to improve their tyre curing process.”

Emerson, not only provides the solution in the curing but also extends its offering to other components in the system. Historically the steam traps used to be checked manually.

If not work correctly, either a large amount of steam can escape or damage the valves and pipework. Emerson offers wireless acoustic transmitters that monitor steam trap health and detect failures in real-time. “The steam trap monitoring system is one of our biggest innovations in energy-saving efforts. With this, we can avoid damage or loss of steam and improve energy efficiency,” said Bart.

As part of its product development, Emerson regularly visits tyre companies to understand the pain point in the production processes. “Looking at their process and our expertise with the components as a solution supplier, we always look into further potential scope in monitoring, measuring and reporting in the tyre production,” said Bart.

For the mixing process, Emerson offers flow control and pneumatic directional control devices, such as pressure operated valves that optimise the mixing process. At a manufacturing production plant, the mixing is a crucial stage that decides the quality of tyres. All ingredients have to be mixed with accurate weight and in a controlled sequence. Emerson valves keep the weighing and hopper systems running efficiently and reliably while ensuring batch quality.

Emerson, for Fabric/wire calendars and extruder, provides products that increase reliability and material guidance precision of bead wiring and rubber coating, improves pneumatic system performance to avoid premature valve failures and reduces commissioning time through onsite/pre-set tuning. The overall company solution can significantly increase the lifespan of valves by purifying compressed air and regulating pressure and improve safety conditions for your workers by locking systems down during maintenance.

Repeatable, high precision pneumatic directional control ensures the production meets the highest quality specifications every time. Using Emerson’s modular and compact valve manifolds tyre manufacturing companies can achieve greater application flexibility, reduce costs, simplify commissioning, maximise the availability of tyre building machinery and achieve higher throughput targets. Increased visibility into the health of valves also lowers maintenance costs, says the company.

In the finishing process, Emerson’s products ensure precise and reliable motion control and positional accuracy. By offering higher repeatability and reliability, these devices reduce machinery downtime and maximise throughput. Emerson’s ISO and NFPA-conforming actuators and linear-guided cylinders are extremely durable, providing greater test equipment machinery reliability and extended lifespans.

According to Bart, the growing complexity in each process of tyre manufacturing is a challenge. “Complexity in mixing, calendering, tyre building, curing and in the finished products is growing, and it is demanding more control on each process. The evolution of the tyre manufacturing processes requires more insights and integration of process information. This enables continuous quality improvements and energy savings.,” said Bart.

Hankook Tire revealed the Design Innovation 2020 project, which defines a vision for the future driving and innovation in mobility.

Launched in 2012, the Design Innovation is Hankook’s R&D project held every two years, in collaboration with one of the world’s leading design universities.

Under the theme ‘Urban Reshaping’, professors and students from the Department of Industrial Design at the University of Cincinnati in the U.S. focused on the transformation of cities geared by reconfiguring mobility as part of living spaces rather than stand-alone purpose in the future with augmented automation infrastructure and cutting-edge technologies such as eco-friendly technology, autonomous driving and Artificial Intelligence (AI).

Throughout the project, modular platform of mobility concept named ‘Hankook Platform System (HPS)-Cell’ was proposed with tyre representing the root of mobility. It is applied with ‘Hankook Electric Mobility Technology (H.E.M.)’ which represents Hankook’s passion for future technological breakthroughs. Then a scenario was created which distinguishes mobility as a moving platform and its function as a pod (space), clearly elaborating that tire indeed sits at the center of the mobility.

The tyre of HPS-Cell embodied an airless tyres’ double-layered unit-cell structure to acquire complex rigidity. It is a concept tyre that uses sensor technology to not only identify tire treads and road conditions in real time, but also to respond to wear-out risks and change tread patterns according to the road condition utilizing variable wheels and optimized infrastructure.

The scenario was brought into reality in a concept film and a mock-up. The productions suggest that in 2040 urban population will be able to use this mobility platform combined with pods of various forms to each meet a specific purpose. The modular platform can also be combined with commercial pods such as urban farming to maximize the scalability and efficiency of movement within smart cities of future generation.

The unveiled productions will be exhibited at various global channels and will represent Hankook’s capabilities in design innovation globally.

Jimmy Kwon, Vice President of Hankook Tire Brand Lab said, “Hankook Tire is incorporating new ideas with our cutting-edge technology to explore design concepts for the next generation, as Hankook believes creativity is the first step towards bringing the imagination into the reality. We are more than excited to present this year’s works as they speak for the essence of the future mobility that Hankook envisions.”

TATNEFT has announced the development of a new line of ATV tyres called the KAMA Quadro ATM. The first model has been made in 25x8-12 standard size at its Nizhnekamskshina factory in Russia.

The ATV tyre, which is developed by Kama Scientific and Technical Center, has been specially designed for off-road driving, providing excellent cross-country ability in mud and snow. The tyre’s special rubber composition ensures high reliability and traction performance.

The first batch of tyres will go for pilot testing to TATNEFT subdivisions that operate off-road special vehicles.

The KAMA Quadro ATM range is currently being developed in nine tyre sizes covering 12 to 14 inches diameter, with nine more sizes coming up over the next year. The factory will begin production of 25x10 tyres for the rear axle in addition to the already manufactured  25x8 tyres intended for the front axle.

The KAMA Quadro ATM will meet the needs of the TATNEFT Group’s all-terrain vehicles used in oil fields and will also be used to equip Russian ATV manufacturers and the secondary market. (TT)

Kumho tyres have outperformed 52 rival manufacturers to ace the Auto Bild magazine’s summer tyre test with its ECSTA HS51 high-performance pattern tyre.

The annual test is among the most comprehensive of its type, the results of which are regarded as highly significant by both the European tyre trade and its consumers.

Conducted on both wet and dry surfaces, it left Kumho in a fighting third place overall. However, while the further qualifications caused the two leaders to slide down the order, 33 of the 53 entries were eliminated by the initial braking test. Kumho’s highly competitive and consistent scores in almost every discipline ultimately left it as the sole test winner.

 Awarding the ECSTA HS51 their coveted ‘Exemplary’ badge, the Auto Bild testers commended it for its precise steering response, secure wet grip, well-balanced handling, short braking distance, low wear rate and affordable price.

Unlike some tyre tests, where the products are supplied by the manufacturers, those for the Auto Bild ones are covertly purchased by the magazine from regular retail outlets. The chosen size was 205/55R16, the direct fitment for the bulk of Volkswagen Golfs and Audi A3s etc., and therefore arguably the one most common within the European car market.

UK purchasers currently have the choice of 35 sizes of ECSTA HS51 for wheels of 15 to 18 inches in diameter. The qualification round of the test was carried out at ATP (Automotive Testing Papenburg) in Germany and the other tests were performed at the IDIADA facility in Spain. 

Thus, our newly developed "Tire Leap AI Analysis" utilises advanced AI-based analysis technology to analyse (for example) electron microscope imagery of tyre rubber compounds in order to achieve high-precision analysis that far exceeds human capabilities, thereby making it possible to derive accurate estimates of rubber properties from structural data found in this imagery.

Specifically, it is a technology that estimates rubber properties precise from combining data on the individual raw materials contained in a rubber compound with data on its internal structure. In the future, we will continue to develop this technology and develop technology to estimate the future rubber properties from electron microscope imagery of unused rubber.

■ Technology to Precisely Estimate Rubber Properties Based on Structures & Materials

Tire Leap AI Analysis utilises an AI-based image analysis system to analyse the internal structures of rubber in images captured by an electron microscope in order to infer information about the properties of the rubber based on its structural data (i.e. the results of image analysis). By combining this structural data with data about the materials that make up rubber compounds, this technology is then able to derive information about the physical properties of rubber with a high degree of precision.

■ Technology to Detect Changes in the Internal Structures of Rubber After Use & Estimate Resulting Changes in Rubber Properties

By comparing images of a tyre that has never been used (i.e. that is brand new) with images of a tyre that has been used (i.e. after wear over time), this AI-based image analysis system can determine where changes have occurred in the internal structures of the tyre’s rubber and then estimate the physical properties of the rubber in the areas that have undergone these changes. The practical application of this technology will facilitate the design of new rubber compounds that are less prone to performance degradation due to wear and tear, thus contributing to the development and advancement of Performance Sustaining Technology.

Dr. Miki Haseyama, Hokkaido University: We have developed a new AI technology that is able to estimate the extent of changes in the structures based on analysis of images of the internal structures of rubber. As compiling data for this kind of machine learning would otherwise be extremely time-consuming, one of the main merits of this new technology is the fact that this AI does not require prior field data from structural changes in rubber for machine learning. Rather, this AI uses deep learning to learn about the properties of new rubber (i.e. prior to undergoing structural changes) and then estimates the extent of changes in the structure by analysing how data from old rubber (i.e. after undergoing structural changes) compares to the data that it has previously learned about new data. This approach to machine learning allows the AI to automatically detect various types of changes in the structures of rubber.

Kiyoshige Muraoka, Senior Executive Officer, Sumitomo Rubber Industries: We have been working jointly with Hokkaido University to further advance the development of AI technology that can understand how the internal structures of tyre rubber change through use. We have already put this new technology to use in the development of our latest “ENASAVE NEXT III” fuel-efficient tyres, which not only achieve the highest possible “AAA-a” rating for fuel efficiency and wet grip performance (under Japan’s tyre labelling system), but also reduce changes in tyre performance that occur over time as a result of use by half. Moving forward, we will continue to advance our Tire Leap AI Analysis technology to find and analyse slight variations in the internal structures of rubber that human senses and knowhow have been unable to detect so that we can then use the resulting knowledge to develop new technologies that further enhance tyre performance and ensure that this high performance lasts longer. In this way, we will accelerate research and development toward producing high-performance tyres that provide greater safety and peace of mind with the aim of contributing to the realisation of a sustainable mobility society for future generations.
