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.

Continental is showcasing ‘The Sound of Premium’, an immersive installation, at Milan Design Week 2026 held at BASE Milano from 20 to 26 April. The experience translates the brand’s advanced tire engineering into a multisensory journey, redefining how urban mobility sounds. Key technologies on display included Continental’s noise-reducing ContiSilent and Urban Silent Technology, which actively lower rolling noise through sound-absorbing materials inside the tire and tread patterns optimised for city speeds.

Cities are dense with movement and noise, where even invisible elements like tyres shape the acoustic environment. Continental’s technologies reduce road noise at its source, enhancing both driving stability and interior comfort. The installation invites visitors to reconsider urban sound not as a nuisance to be eliminated but as an element that can be precisely engineered and controlled.

The exhibition unfolds in three distinct phases: chaos, harmony and quiet. Layered city sounds first create tension and disorientation, then gradually dissolve as rhythm and balance emerge. The journey ends in a state of calm defined not by silence alone but by acoustic precision. A tyre displayed as a design object underscores how engineering can improve urban well‑being.

An interactive installation of 25 touch points allows visitors to shape their own sound environment in real time, activating different acoustic layers through touch. Each participant creates a personal composition reflecting their rhythm and sensitivity. The resulting experience can be recorded and shared via QR code, extending the dialogue between technology and individual expression beyond the exhibition space.

As electric vehicles become more widespread, rolling noise has grown into a dominant source of urban traffic sound. Continental meets this challenge by applying its expertise at the tyre‑road interface, developing measurable reductions in interior noise. Through ‘The Sound of Premium’, the company positions silence not as emptiness but as a performance feature.

Nokian Tyres plc has introduced a new long-term share-based incentive plan for management and key employees, as the company seeks to align executive rewards with shareholder returns.

The board of directors said the Performance Share Plan (PSP) would cover the company’s management and selected key personnel, with the aim of supporting shareholder value creation and reinforcing commitment to strategic objectives.

The plan, titled PSP 2026–2030, comprises three separate plan periods, each with a three-year performance cycle followed by the payment of potential share rewards. The start of each period will be determined by the board, and any rewards will be paid in company shares.

The first phase, PSP 2026–2028, will assess performance against three criteria: relative total shareholder return, weighted at 50 per cent; average return on capital employed (ROCE), at 40 per cent; and a 10 per cent weighting for reduction in Scope 1 and 2 carbon emissions intensity.

Subject to meeting these targets, rewards will be delivered by the end of April 2029.

The maximum number of shares that may be distributed under PSP 2026–2028 is 1,258,000, representing the gross value of the rewards before applicable taxes are deducted.

Approximately 100 participants are included in the first plan period, including the president and chief executive and members of the group management team.

Under the plan’s terms, participants who leave the company before rewards are paid will generally forfeit their entitlement.

The president and chief executive, together with other senior executives, must retain 25 per cent of the shares received until their personal shareholding equals their gross annual salary from the preceding year.

The board said no new shares are expected to be issued under the plan, meaning it is not anticipated to dilute the company’s existing share base.

The Global Platform for Sustainable Natural Rubber (GPSNR) has launched a three-year collaboration with the Berlin-based social enterprise Elucid to provide healthcare access for 1,800 rubber farming households in Côte d’Ivoire. The initiative, funded through GPSNR’s Shared Investment Mechanism, will benefit approximately 9,000 individuals. Financial backing comes from 13 major tyre and rubber manufacturers, including Aeolus Tyre, Apollo Tyres, BKT, Goodyear, Hankook, Kumho Tire, Maxxis International, Nokian Tyres, Prometeon Tyre Group, Sumitomo Riko, Sumitomo Rubber Industries, Toyo Tire and Yokohama Rubber. The programme directly confronts a long‑ignored reality within the natural rubber sector: the link between farmer health and supply chain stability.

Côte d’Ivoire ranks 187th out of 195 nations for quality of care, with only 32 percent of essential medicines available publicly. Although two‑thirds of the population are enrolled in national health insurance on paper, fewer than four percent used their card in 2025. Medical emergencies cost the country an estimated 853 million US dollars in cocoa exports in 2017 alone, and with many farmers growing both cocoa and rubber, the implications for the rubber sector are substantial.

The partnership integrates four measures: enrolling families into national insurance, providing an emergency care package covering WHO‑accredited medications, upgrading 15 local health facilities and running community awareness programmes. Elucid’s digital platform will track data in real time. The project aims to increase healthcare visits from under 200 to over 1,800, push insurance enrolment from below 30 percent to above 90 percent and prevent more than 150 catastrophic health expenditure events annually. Half of beneficiaries will be women, and 20 percent children.

Farmer enrolment begins in August 2026, with improvements continuing until January 2029. Without reliable healthcare, medical emergencies force farmers to sell assets and abandon farm improvements, creating direct risks for supply chains. The programme seeks to reverse that dynamic, targeting long‑term sustainability by building cooperative capacity to maintain health support for members.

Stefano Savi, CEO, GPSNR, said, “We talk constantly about improving yields and farm management practices, but we’ve missed something fundamental. A farmer who can’t afford to see a doctor when they’re sick or who cannot go to the farm because their child is unwell can’t be productive. Healthcare isn’t separate from supply chain resilience. It’s central to it.”

Sambhavna Biswas, Partnerships Manager, Elucid, said, “This is about demonstrating what’s possible when the private sector invests in making national health systems work for farmers. This model can be replicated across rubber-growing regions and adapted to other agricultural sectors. Everyone in the value chain benefits when the people at its foundation are healthy and economically secure.”
