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:

• Technical support for restarting the HF Curing Presses

• Inspection and readjustment of mechanical settings

• Inspection of safety-related components

• Performance check and functional analysis of hydraulic/pneumatic systems

• Software check-up and functionality test

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 unveiled its latest innovation in road racing, the P ZERO Race TLR SL-R, a tyre engineered with a singular focus on maximising on-road speed. Positioned at the apex of the P ZERO Race lineup, this model unifies aerodynamic efficiency, low rolling resistance, precise handling and dependable grip into a single high-performance package. It is tailored for any scenario where speed is paramount, from competitive time trials and road races to the pursuit of personal bests during weekend rides.

The development of this tyre was heavily influenced by real-world feedback from Pirelli’s WorldTour partners, including Alpecin-Premier Tech, Fenix-Premier Tech and Lidl-Trek, alongside collaborations with leading bicycle manufacturers. Before its official release, it was already being raced under a prototype label, proving its pedigree in elite competition.

Central to its design is the debut of a patented technology called PAAS, or Pirelli Advanced Aerodynamic System. This system redefines the tyre’s shape to optimise its interaction with the rim, effectively managing airflow to harness the sailing effect, which reduces overall drag. By refining the tyre’s mounted geometry and the precise placement of its widest point, PAAS delays airflow separation. Importantly, this aerodynamic gain comes without sacrificing other key attributes, allowing the tyre to retain top-tier rolling efficiency, comfort and handling for a truly balanced ride. Complementing this is a newly developed micro-textured surface on the slick tread, further fine-tuning airflow to enhance aerodynamics and road feel at high speeds. The result is a tangible reduction in wheel drag, with average savings of up to 5 watts in crosswinds and peaks reaching 15 watts under optimal conditions.

Speed is further reinforced by the new LiteCORE casing, a tubeless-ready structure that represents Pirelli’s lightest and most efficient design for road tyres. It achieves a 10 percent reduction in rolling resistance compared to the brand’s previous best, all while maintaining responsive acceleration and precise control across varying conditions. The tyre delivers confident handling during rapid direction changes, accelerations and high-speed cornering.

Grip is entrusted to the SmartEVO² compound, a race-proven material already responsible for victories at prestigious Classics like Milan-Sanremo and Paris-Roubaix. This compound ensures reliable traction on both dry and wet surfaces, broadening the tyre’s versatility. Manufactured in Italy using FSC-certified natural rubber, the tyre complies with current ETRTO standards and is optimised for modern rims with internal widths between 22 and 25 millimetres, including hookless models when pressure limits are observed. Initially available in 28- and 30-millimetre widths, with black or yellow sidewall options, a 32-millimetre version is planned for release later in the year.

Pirelli is all set for the Japanese Grand Prix with the three hardest compounds in its range – the C1 as the Hard, C2 as the Medium and C3 as the Soft – marking the first appearance of the C1 in race weekends of the 2026 Formula 1 season. Suzuka’s legendary 5.8-kilometre figure-of-eight layout, with its eighteen demanding corners and rapid directional changes, places immense stress on tyres, making this selection essential.

Recent resurfacing work, which began ahead of the 2025 event and has since been substantially completed across the remaining two sectors, introduces a smooth but still dirty asphalt surface expected to offer low initial grip. Under these conditions, graining – particularly on the Soft compound – is a typical concern. Last year, such wear was limited to the front axle and faded as the track evolved. With a larger expanse of new asphalt this time, teams will need to closely monitor both graining and its effect on degradation throughout the weekend.

The behaviour of the hardest and softest compounds will be especially telling. If the C1 delivers solid grip and the C3 shows the consistency seen in Shanghai, all three tyre options could become viable for race strategies. Temperatures will also play a decisive role. With the race held a week earlier than last year, ambient conditions may stay near 15°C, keeping thermal degradation in check. Whether a one-stop strategy remains feasible will likely hinge on the severity of graining and its impact on performance, making qualifying preparation critical for properly heating the tyres.

The 2025 race saw a dominant one-stop approach, with most drivers starting on the Medium before switching to the Hard around lap 20 – a path taken by the entire podium finishers. As the 40th edition of the Japanese Grand Prix approaches, Suzuka continues to host the event except for four early editions held at Fuji. Michael Schumacher holds the record for most wins here with six, while McLaren leads constructors with nine victories.

Adding a distinctive local touch, the third podium cap crafted by Pirelli Design with designer Denis Dekovic draws inspiration from cherry blossoms in full bloom during this period. The cap is available through Pirelli’s online store.

TyreSafe, UK’s charity dedicated to raising tyre safety awareness, is calling for a shift in driver mindset, moving beyond reliance on enforcement to foster a culture of proactive vehicle safety. This follows new research from Uswitch that exposes a disconnect in how motorists approach maintenance. While the threat of penalty points prompts some action, it falls short of establishing consistent safety habits. TyreSafe argues this ‘safety gap’ reveals the limitations of an enforcement-led strategy, suggesting true road safety depends on motivating drivers to perform checks to protect lives rather than merely avoid punishment.

The findings paint a complex picture. Although over 4.8 million penalty points were issued in 2025, with the vast majority linked to speeding, only a third of motorists conduct vehicle checks specifically to evade penalties. While a significant majority of drivers with existing points altered their behaviour after being penalised, only half believe penalty points enhance road safety. For TyreSafe, this highlights a clear challenge: consistent vehicle maintenance has not yet become an automatic, routine part of driving habits.

This gap between awareness and action is particularly critical for tyre safety, a ‘silent risk’. Unlike speeding, which is highly visible and rigorously enforced, tyre defects often go unnoticed until they contribute to a serious incident. The statistics are stark, with an estimated six million illegal tyres on UK roads. Each year, tyre defects cause over two million MOT failures and result in thousands of penalty points. Given that tyres are the vehicle’s only contact with the road, their neglected state represents a persistent and underestimated danger.

In response, TyreSafe advocates for education alongside enforcement, warning that relying on fear of fines fosters reactive compliance rather than a preventative mindset. To address this, TyreSafe urges road users to embrace the simple ACT protocol: regular checks of air pressure, condition and tread depth. By encouraging drivers to internalize these routine habits, TyreSafe believes it is possible to bridge the gap between knowing what is safe and consistently acting on it, preventing thousands of needless incidents caused by poorly maintained tyres.

Stuart Lovatt, Chair of TyreSafe, said, “Enforcement clearly has a role to play in improving driver behaviour, but it cannot be the only motivator. What this data highlights is a safety gap. If only a third of drivers are checking their vehicles to avoid penalty points, we need to ensure everyone is checking them for the right reason – to stay safe. Tyres are a hidden risk. Unlike speeding, they’re not always visible and often go unchecked until something goes wrong. But when tyres fail – whether through low tread, incorrect pressure or damage – the consequences can be immediate and severe. The reality is that many tyre-related incidents are entirely preventable. A few simple checks, carried out regularly, can make a life-saving difference. We need to move beyond a culture of compliance driven by enforcement and towards one where tyre safety is seen as a fundamental part of responsible driving.”

Falken Motorsports kicked off its new season in commanding fashion, leveraging the performance of Falken racing tyres to secure a podium finish at the 58th ADAC Barbarossa Prize. This event, originally intended as the second round of the ADAC RAVENOL Nürburgring Endurance Series (NLS) but elevated to the season opener after a cancellation, saw Sven Müller and Tim Heinemann claim third place in the No. 44 Porsche 911 GT3 R.

After qualifying 10th despite not completing a perfect lap, the duo demonstrated the tyres’ full potential. Starting driver Müller engaged in fierce battles from the opening lap, and the pair steadily advanced in their teal-and-blue Falken Porsche through the field to reach the top five by mid-race. In the closing stages, Heinemann delivered decisive overtakes, coming within a second of second place on the final lap to seal an early-season podium.

For customer team Max Kruse Racing, the Audi R8 LMS GT3, running on alternative fuel, finished 23rd with Jan Jaap van Roon, Tom Coronel and Rudy van Buuren. The sister car, driven by Dominik and Marcel Fugel alongside Benjamin Leuchter, placed 30th, while both VW Golf GTI TCR entries retired early. Falken Motorsports now prepares for the 57th Adenauer ADAC Rundstrecken-Trophy on 11 April, the third NLS round, building towards the ADAC RAVENOL 24h Nürburgring (14–17 May).
