The new headquarters of the Group, which has a history of 165 years of steady growth, serves the business units HF TireTech Group and HF ToolTech Group.

The designing of the new office is tuned to the needs of the Group’s forward march. Direct access from the office facilities to the assembly hall and machine testing area brings all fields of work close together and ensures optimised communication. The established and well proven production unit in Belišće, Croatia remains. Continuous investments in logistics, painting, warehousing and machining under highest economic aspects guarantee state of the art manufacturing.

Back on track

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.

HF´s benefits & services for the tyre production are many:

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.

Pirelli has designated the SC0 rear tyre as the new benchmark for Moto2 as the MotoGP World Championship resumes its season this weekend at Silverstone for the 12th round. The Italian manufacturer is supplying its standard range compounds for both support classes, with the updated SC0 making a notable return to the British circuit following its successful evaluation there last year.

The 2026-spec soft rear tyre, which initially debuted as a development prototype, features an altered structure from its predecessor and was universally embraced by competitors during practice sessions, even contributing to a new lap record. Its promotion to the standard lineup sees it joined at the rear by the new medium SC1 compound, formerly a development specification, while front tyre duties are covered by the soft SC1 and the medium SC2 options.

Silverstone presents a formidable technical challenge as the longest venue on the calendar at 5.9 kilometres, demanding exceptional machine and rider performance through high-speed corners and rapid directional shifts. The circuit’s low-abrasion surface and notably wide racing corridor allow for varied lines, adding another layer of strategic complexity to the already fast-paced weekend.

In the Moto3 class, Pirelli has made available the soft SC1 and medium SC2 compounds for both front and rear positions. The majority of the field last year favoured the medium SC2 at both ends, a choice that propelled José Antonio Rueda to victory from the back of the grid, though a segment of riders alternatively selected the softer SC1 option for their machines.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “For this weekend's round at Silverstone, one of the most iconic and technically demanding circuits on the World Championship calendar, Pirelli will once again provide standard range tyres for both classes, featuring the rear soft SC0 compound that made its Moto2™ debut at this very circuit last year as the E0125 development option. The E0125, which complemented the then standard soft tyre, was immediately appreciated by the intermediate class riders, who, on a highly demanding circuit characterised by numerous high-speed corners and changes of direction where stability is essential, focused exclusively on this new solution from Friday onwards.

“Introduced again at subsequent events, the former E0125 quickly became the Moto2™ riders' benchmark, offering greater stability, outright one-lap performance and consistent performance across a wide variety of weather and track conditions. As a result, it was promoted to the new standard soft tyre for this season. More than a year after its debut, and thanks to the significant development work carried out by the teams during this period, the SC0 has already contributed to numerous lap records this season. Weather conditions permitting, it will therefore be interesting to see whether Silverstone can deliver further progress compared with last year's benchmark.”

Hankook Tire, the exclusive tyre supplier for the FIA World Rally Championship, played a central role in the season's 10th round at Secto Rally Finland. The event concluded on 2 August in Jyväskylä, where the company’s Dynapro R213 extreme all-terrain rally tyre was put to the ultimate test across the demanding Finnish landscape.

Competitive action unfolded over 20 Special Stages, covering a total distance of 316.04 kilometres. Renowned as the fastest rally on the WRC calendar, the event subjected vehicles and tyres to extreme speeds. The challenging route was characterised by blind crests that impaired visibility, frequent jumps and narrow forest roads, placing a premium on tyre durability and overall driving stability.

The supplied Dynapro R213 tyre proved instrumental in managing these severe conditions. On the ultra-high-speed gravel sections, it effectively absorbed the impact of repeated landings while delivering consistent grip and precise steering response. Its robust construction ensured reliable performance across the loose dirt and forest roads, allowing competitors to push their vehicles to the limit.

Sami Pajari of Toyota GAZOO Racing claimed a home victory, securing back-to-back wins after his success in Estonia. This result advanced him to second in the Drivers’ Championship with 171 points. Looking ahead, Round 11 is the ueno Rally del Paraguay from 27 to 30 August, featuring gravel stages that will demand exceptional tyre resilience. Hankook applies data from its WRC involvement and other global motorsport events to its R&D, fostering continuous innovation and reinforcing its status as a leading global brand.

Legislation aimed at overhauling decades-old federal tyre safety regulations has been introduced in the United States Senate. The Tire Safety Modernization Act of 2026, sponsored by Senators Roger Wicker of Mississippi and Raphael Warnock of Georgia, seeks to replace outdated testing mandates with contemporary performance standards that better reflect current manufacturing innovations and production techniques.

The proposed bill directs the Department of Transportation to revise federal testing protocols, retiring obsolete requirements in favour of more relevant criteria. A key component of the legislation involves aligning high-speed testing procedures with internationally recognised best practices while also clarifying existing safety criteria to ensure more effective regulatory oversight. The measure preserves a strong emphasis on passenger safety while adapting to the capabilities of modern tyre engineering.

Strong support for the initiative has emerged from the tyre manufacturing sector. Anne Forristall Luke, President and CEO of the U.S. Tire Manufacturers Association, praised the bipartisan effort as a crucial step towards aligning American rules with technological progress, bolstering road safety and enhancing the industry’s global competitiveness. Executives from major manufacturers, including Continental Tire, Goodyear and Yokohama, have similarly endorsed the update, noting that it would allow engineering and compliance resources to focus on innovations that genuinely benefit drivers.

Senator Warnock highlighted the importance of Georgia’s prominent tyre production sector, while Senator Wicker emphasised that federal regulations have failed to keep pace with evolving manufacturing technology. Industry leaders collectively view the act as a thoughtful, science-based modernisation that supports domestic manufacturing competitiveness and ensures that safety standards reflect the demands of modern vehicles, roads and driving conditions across the country.

Bridgestone's e-CENTRE Excellence Programme has delivered a significant financial boost to two community organisations in South London, with nearly GBP 1,000 raised through a charity initiative run by Merityre Southfields, a flagship Bridgestone e-CENTRE. The campaign generated a total of GBP 938, which was evenly distributed between St Michael's Church Social Projects and the Friends of Wimbledon Park, both of which are vital to the Wandsworth area.

Over a five-month period spanning November and December 2025, as well as February to April 2026, motorists were given a one-pound donation token with every Bridgestone tyre purchased. Customers were then able to choose which of the two local causes would receive their contribution, resulting in GBP 464 for St Michael's and GBP 474 for the Friends of Wimbledon Park.

The funds allocated to St Michael's Church Social Projects will finance the installation of an additional water tap at its Kitchen Garden Project, located on the Church Memorial Field. Since its establishment in 2020, the garden has expanded into a productive allotment with over 30 raised beds, providing fresh organic produce for community lunches and a weekly food bank. The new tap is expected to reduce watering time for volunteers, enabling them to dedicate more attention to the retired, unemployed, isolated and vulnerable individuals who rely on the project for support, skill development and social connection.

Meanwhile, the Friends of Wimbledon Park will direct its share towards a new seating area in the Waterfall Garden, with any leftover funds supporting tree and bulb planting as well as maintenance materials. This retail-led effort exemplifies a core component of Bridgestone's broader e-CENTRE Excellence Programme, which has allocated over GBP 1 million to encourage retailers to adopt sustainable practices and foster positive social and environmental change within their localities.

Dene Arnold, Director, Merityre, said, “As a business rooted in the local community, we wanted to give our customers the opportunity to support causes that really matter to people in Southfields. We're incredibly grateful to everyone who got behind the campaign and helped us raise such a fantastic amount. Being part of Bridgestone's e-CENTRE network is about much more than providing premium products and services. It's about making a meaningful contribution to the communities we serve and creating a positive impact beyond the garage doors. It's especially rewarding to know exactly where the money is going. Whether it's helping volunteers continue to grow fresh produce for people in need or creating new spaces for the community to enjoy in Wimbledon Park, these are projects that will make a lasting difference locally.”

Gresia Cabrera, Bridgestone's Business Development Manager and project lead for the e-CENTRE programme, said, “Community engagement sits at the heart of the eCentre philosophy, so it's fantastic to see Merityre Southfields bringing that vision to life. The team continues to demonstrate that modern tyre retailers can be a force for good, supporting local people and causes while delivering outstanding service for motorists. Initiatives such as this show that the industry can make a genuine difference and create value far beyond tyres alone. One of the strengths of the e-CENTRE programme is that it empowers retailers to make a meaningful impact in the communities they serve. Seeing these donations translated into practical improvements that will benefit local people for years to come is exactly what the programme is all about.”
