The COVID 19 pandemic and the global lockdown that came with it saw HF being tested hard for its resilience and the capability to help its partners put their production process back on track through its engineering and other services.

“For HF, partnership means to support its valued customers with benefits that will help to keep their production back on track,” says HF TireTech Group Managing Director Dr. Joern Seevers.

Dr. Seevers said: “Together with our customers we analyse production processes, optimise, adjust to changed situations, look behind the production and develop new strategies to achieve more flexibility, increase quality, reduce costs and raw material - get into action with a higher level in automation and smart retrofitting and be ready for sustainable tyre production.”

Tandem Mixer technology:

HF takes it to the next level

HF Mixing Group is supplying Tandem Mixers for more than 15 years and has kicked off a revolution in mixing since then. The concept appears to be simple, but all those years of experience have shown that the highest degree of machine engineering has to be combined with extensive process know how to make a Tandem Mixer successful. And a mixing line is only successful if the calculated output and productivity is achieved – combined with a reliability which enables stable production for years.

As matter of fact to develop the process to mix on a Tandem Mixer takes some time and efforts – not to forget the technological know-how of the mixing process itself. HF offers the possibility to accompany this development by offering extensive trials and engineering studies – to shorten the time from ordering a machine up to the point of running in full production.

The goal of a Tandem Mixer is to reduce the specific cost of mixing a compound – on many occasions, HF has proven that overall cost reductions of 15% can be achieved compared to standard lines with a single mixer. This, in between other, is achieved by reducing the mixing steps for a PCR compound from 2,5 to 1,5 steps.

But productivity is not the only driving factor to invest in a Tandem Line – the quality of the compound overall and specifically constant and repeatable mixing of modern compounds is to be ensured. To optimise dispersion, distribution, temperature control and process stability makes a significant difference in today’s production of more complex compound recipes. The intermeshing mixers produced by HF and used in a Tandem Line guarantee to meet these requirements more than any other mixers on the market.

Experiences have shown that no compromise on quality can be made – and HF is supporting this approach with delivering a control system for Tandem Lines which enables their customers to not only run the machine efficiently but also uses online condition monitoring to always reflect on a reliable compound quality which is repeatable.

HF emphasises on result driven production concepts for its customers – further innovations in terms of integrating industry 4.0 solutions to the mixing process are on its way and the focus is clear: Intelligent machines will integrate new digital solutions into the mixing process and will ensure to meet the expectations of the future.

Brownfield projects

The COVID pandemic put a stronger focus on replacing existing machines instead of adding new capacities to a production plant. Also, productivity as well as sustainability aspects are driving many tyre companies to have a closer look to the installed base.

But inspecting a mixing line which has run for more than 15 years (or sometimes even 25 years) brings to light what challenges may come up if this line will be replaced by a new one. Output values need to be increased, a new mixer technology should improve the quality of compounds, modern automation solutions should support the daily production procedures and increase process stability – many more requirements should be met. One of the largest challenges is limited space when looking at an upgrade of machinery.

Not only the pure space but also intralogistics within a mixing line can create headache – from upstream equipment feeding a mixer all the way to downstream machinery processing the batch further – many modern solutions can be used today but looking at the available space installing them is the challenge.

With a clear focus on such brownfield projects, HF has managed several conversions from old to new with unmatched success. A key in such projects is the planning and pre-engineering process. Starting with an inspection of not only the mixer but all surrounding factors in the building – considering also the material flow – and then continuing with a 3D- scan of the existing equipment including pipe and cabling routing the basis for planning can be laid. Supported by this 3D-scan HF engineers plan and design with 3D models the complete mixing mill room.

By keeping the existing machinery as the base layer and inserting new equipment in an over-lay collisions of steel constructions, limitations in space and optimised pipe and cable routing can be identified. Furthermore, an improved process flow chart is the basis of planning material flow, work processes and even manpower to operate the new mixing line. Finally, new controls and automation solutions – on the basis of industry 4.0 – will improve operating and monitoring the equipment.

One of the largest benefits using HF’s Pre-Engineering is shortening the planning and execution time – and last but not least the reduction of financial funds is possible by starting up the new line much quicker compared to the conversion of lines in earlier years.

Safety first

Supporting all major tyre manufacturers with mixing technology HF constantly strives for improving operational procedures in the mixing mill room. When it came apparent that the variety of compounds increased more and more – driven by many more types and technologies in tyres today – the changeover times from one recipe to the other was put in the focus of operational optimisation. Not only flexible automation solutions are required but also quick availability of the mechanical equipment after the last batch of the current recipe was dispatched. In between other HF identified the cleaning of the mixing chamber as a critical action during changeover in two aspects: First it needs to be safe for the maintenance personal to enter the mixing chamber and secondly time can be saved if the access to the chamber can be optimized.

In order to meet both requirements HF’s engineers designed a maintenance box, the so-called mBox©, which is mechanically integrated directly underneath the mixer – combining the mixer with the chute of a dump extruder for example.

In the moment the mixing line is switched to cleaning mode and all movements of parts are blocked a moveable platform – the floor of the maintenance box – is inserted horizontally underneath the mixer. A door of the box can be opened, and maintenance personnel can enter the box safe and secure, standing underneath the mixer with easy access to the mixing chamber.

Besides the safe working environment customers from HF have noticed saving time and having the opportunity of even inspecting the mixing chamber easier and more frequent during a changeover.

Especially in new installations of a mixing line the mBox© can be integrated in the design of the line easily and right from the start – benefitting the safety and operation of the line daily.

HF Screw Presses

The production of screw presses is one of HF`s core competences for decades. The screw press has gained recognition during its affiliation with KRUPP. Thus, the presses operate all over the world and more than 2.500 presses are installed in various industries for example the edible oil industry, biomass technology and rendering. And, most interesting for the tyre industry, the presses accomplish benchmarking results in the dewatering of natural and synthetic caoutchouc. As a more efficient and space saving solution instead of band dryer systems or similar the screw press has its strong eligibility in dewatering process.

HF Curemaster

HF brought the first hydraulic column type curing press to the tyre industry in 1997. Since then, it continued to develop this product to meet the demanding requirements of its customers.

The HF Curemaster was launched two years ago and since then the patented truck tyre curing press has been successfully installed in multiple locations and in efficient operation. The press provides a flexible and compact footprint, making it possible to replace older presses with potentially more presses per existing trench.

The HF Curemaster also focuses on optimising energy efficiency to ensure the lowest total cost of ownership in the curing plant. The HF Curemaster´s hood design incorporates insulation inside the hood to provides the best insulation effect. In addition, the HF Curemaster provides an extremely fast cycle time to minimise the overall amount of heat loss during the open and close sequence of the press.

HF PCR Design

Delivering for a new greenfield plant is relatively straightforward. However, HF understands the important need of the replacement market as well. It is important to be flexible to meet all the varying trench layouts (pit, shelf, pitless, and so on). Equally important is the need to be able to replace existing 42” – 45” old mechanical presses with 48” – 52” modern presses in order to meet the growing demand for larger tyre sizes.

All replacement projects are analysed carefully together with customers. Attention is paid closely to all details related to operation, maintenance access, mould & bladder change requirements as well as all local safety regulations. HF´s long experience with curing presses provides a large variety of modular options to be used for finding the optimised fit for each specific request.

HF Stack Passenger Car Inflator (PCI)

The requirement for post cured tyres continues to grow in the market and HF has designed a simple and compact solution that can be incorporated in all HF presses as well as behind most all existing older presses.

The patented HF Stack PCI design allows for the PCI to be integrated into even the tightest footprints. This solution eliminates any movement or rotations of the PCI body itself and greatly reduces the amount of moving mechanical components and maintenance.

HF Digitalisation

HF recognises the important trend of digitalisation for the tyre manufacturers and has developed reliable, customised software solutions for machine data communication between machine control and customer IT systems. The main steps were to focus on MES, SCADA and Recipe Management interfaces.

HF Smart Curing enables customers to get started quickly and effectively with a future-oriented digitisation solution. The main advantage in this case is that software for machine data acquisition is supplied directly by the supplier and not by IT service providers.

OPC server technology and efficient network solutions are tailored to the machine enable secure data acquisition. This software can provide feedback in regard to condition monitoring, diagnostic function, machine services, energy monitoring and remote service.

The benefit of connecting your equipment with digitalised solutions clearly accelerates a target-oriented development and improves the Total Cost of Ownership of the equipment.

India’s tyre industry has secured a stronger foothold in the global market, with four domestic manufacturers ranked among the world’s top 20, according to the latest Global Tyre Report released by Tire Business based on 2024 sales.

MRF was the highest-placed Indian company, taking the 13th spot worldwide. Apollo Tyres followed at 14th, while JK Tyre & Industries ranked 19th. CEAT entered the top 20 for the first time, securing 20th position and underscoring the country’s growing influence in the global tyre trade.

“The presence of four Indian tyre companies among the world’s top 20 is a matter of immense pride for the Indian manufacturing ecosystem. It reflects not only the scale we have achieved, but also the focus on technology and global competitiveness that Indian companies have pursued. This milestone is a validation of India’s emergence as a global hub for high-quality, value-driven tyre manufacturing,” said Mr Rajiv Budhraja, Director General of the Automotive Tyre Manufacturers Association (ATMA).

Indian companies have been steadily climbing the global rankings over the past decade. Apollo Tyres has moved up three places since 2013, while JK Tyre has advanced six positions in the same period. CEAT has shown the fastest recent progress, rising three spots in just the last year.

The country’s manufacturing strength is also reflected in its industrial footprint. China leads with 158 tyre plants, followed by India with 67 and the United States with 44. This places India as the world’s second-largest tyre manufacturing base by number of plants.

In Asia, MRF holds the second-largest manufacturing footprint with 10 plants, trailing only Bridgestone, which operates 19. Indian companies have also built strong positions in specialised and high-performance categories. MRF is the world leader in racing tyre manufacturing with three plants. It also ranks second in motorcycle tyres with four plants, followed by CEAT with three. In the farm tyre segment, MRF again ranks second globally with seven factories.

Investment has played a central role in this expansion. Apollo Tyres recorded the highest capital expenditure globally as a share of sales, reinvesting 59% into expanding and modernising its operations. MRF also ranked among global leaders, with capex exceeding 10% of sales.

Long-term prospects remain robust. A recent report by ATMA and PwC India, titled Viksit Bharat 2047: Vision and Roadmap for the Indian Tyre Industry, forecasts that India’s tyre production could nearly quadruple by 2047, while industry revenues may grow nearly twelvefold to about ₹1,300,000 crore.

“With strong domestic demand, rising exports and policy support under the vision of a Viksit Bharat, we are confident that Indian tyre manufacturers will continue to move up global rankings and play a defining role in the future of global mobility,” Mr Budhraja added.

In a significant move to bolster its international profile, Linglong Tire has entered a global partnership with Chicago Bulls, the iconic NBA team. This alliance represents a strategic advancement in the company's global sports marketing, building upon previous high-profile sponsorships with Chelsea FC and Real Madrid. The primary objective is to substantially enhance brand recognition for its product lines, including Green Max, Atlas and Evoluxx, across the crucial North American market, with promotional activities also extending into Europe.

This marketing initiative is strategically aligned with the company's operational expansion, notably a new manufacturing facility under construction in Brazil, which is expected to optimise supply chains and support a drive for increased market share in the Americas. The collaboration has been designed to create meaningful fan engagement through co-developed activation strategies. These will include immersive experiences such as joint basketball camps and interactive tours, aiming to forge a powerful connection with a global community passionate about basketball and high-quality, innovative tyres.

The Yokohama Rubber Co., Ltd. has confirmed a continued partnership that will see its US subsidiary, Yokohama Tire Corporation, provide ADVAN racing tyres for three Porsche one-make racing series in 2026. This multi-series agreement includes the Porsche Sprint Challenge North America by Yokohama, the Porsche Sprint Challenge USA West by Yokohama and the Porsche Endurance Challenge North America. All three are sanctioned by the United States Auto Club (USAC) and function as key developmental categories within the Porsche Motorsport Pyramid, featuring race-prepared vehicles such as the 911 GT3 Cup and the 718 Cayman GT4 RS Clubsport.

The upcoming 2026 season represents a significant milestone, marking the sixth consecutive year Yokohama has been the control tyre supplier for the North America and USA West series and the third straight year for the Endurance Challenge. The company will support the competitors with its ADVAN A005 for dry tracks and the ADVAN A006 for wet weather conditions across a combined schedule of numerous events. This ongoing involvement is a strategic initiative designed to bolster the profile and recognition of the ADVAN brand throughout the important North American market.

This commitment to one-make racing extends beyond the Porsche family. Yokohama Rubber is also the official control tyre supplier for the recently launched Mustang Cup, reinforcing its active role and investment in North American motorsport. Through these high-profile partnerships, Yokohama aims to enhance brand power by associating its ADVAN products with some of the most exciting and competitive racing series on the continent.

Continental has demonstrated its role as a key partner for sustainable fleet management through its collaboration with Italian transport company Adami Trasporti. Since 2023, Continental has supplied its Conti Hybrid series tyres – Conti Hybrid HS5, Conti Hybrid HD5 and Conti Hybrid HT3 – to Adami's fleet, leading to significant reductions in the company's total operating costs and a marked improvement in its environmental performance. This partnership underscores how strategic tyre selection is central to modern logistics.

For Adami Trasporti, a family-owned business specialising in food transport for over four generations, operational integrity is paramount. The company operates a fleet of 200 modern tanks and tank containers for sensitive liquid goods like fruit juice, wine and cooking oil, requiring adherence to the highest hygiene standards and strict EU environmental regulations. To meet these demands, the Verona-based firm, with additional locations in Italy, Slovakia and Germany, invests heavily in technological innovations, from real-time data monitoring to modern vehicles designed for minimal emissions.

Within this comprehensive sustainability strategy, the choice of tyres has proven to be a critical factor. While tyres themselves account for a small fraction of direct operating costs, their influence on fuel consumption and CO2 emissions can affect up to 31 percent of a fleet's total costs. Continental is actively informing the logistics industry that a shift in focus from mere tyre mileage to rolling resistance is essential. Tyres with optimised rolling resistance, such as the Conti Hybrid models, serve as a direct lever for saving fuel, lowering costs and reducing a fleet's carbon footprint.

This aligns perfectly with Adami Trasporti’s concrete goals for greater sustainability. The company complements its use of Continental’s tyres with other forward-thinking initiatives, most notably the integration of LNG-powered vehicles that cut nitrogen oxide emissions by 70 percent. Through this multi-pronged approach, in which Continental’s tyre technology plays a fundamental role, Adami Trasporti positions itself as an industry pioneer. Together, the companies are actively contributing to lower CO2 emissions across the European transport sector.

Stefano Adami, owner at Adami Trasporti, said, “With the rolling resistance-optimised tyres, we are reducing our CO2 emissions, saving fuel and benefiting from high mileage at the same time. The fuel savings of one and a half to two percent are crucial for us, as consumption has a direct impact on our operating costs. The service and support offerings increase operational reliability of our vehicles and enable us to offer consistent and punctual services throughout Europe.”
