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.

Hankook Tire has completed a significant expansion of its European manufacturing facility in Rácalmás, Hungary, marking the company's first production of truck and bus tyres on the continent. The new line, representing an investment of EUR 540 million, is scheduled to commence operations in October and has been configured to deliver more than 800,000 units annually. The first pre-production tyre from these facilities was officially unveiled at the ongoing IAA Transportation exhibition.

Previously, Hankook supplied European commercial vehicle customers exclusively from plants in Korea and China. The Hungarian line substantially reduces delivery distances, strengthening supply reliability and cutting lead times. Logistics-related carbon dioxide emissions also decline as lengthy transport routes from Asia are partially eliminated. Europe represents roughly 45 percent of Hankook's worldwide sales, making it a critical market for the tyre maker.

The Rácalmás site has received approximately EUR 856 million across three earlier expansion phases since 2007, with the third stage finishing in spring 2015. It now produces as many as 17 million tyres yearly for passenger cars, SUVs and light commercial vehicles. The fourth phase added the truck and bus tyre line and has seen around 66,000 square metres of production and support buildings constructed since 2024. More than 450 local jobs are being created. Globally, Hankook operates eight plants with capacity for up to 100 million tyres annually and employs about 20,000 people.

Designed as a highly automated facility, the new line relies on automated logistics systems, autonomous guided vehicles and real-time tracking to manage material flow and warehousing, while automated testing ensures consistent quality. Sustainability guided planning and operation through energy-efficient systems, optimised supply infrastructure and modern process controls that lower energy and water use. The plant earned ISCC PLUS certification in 2023. Production will initially centre on 22.5-inch truck and bus tyres, gradually broadening as capacity and approvals allow.

Jongho Park, President and COO, Hankook Tire Europe, said, “The expansion of our European production plant with a new line for truck and bus tyres is yet another key milestone for Hankook in Europe. The central location of the facilities in Hungary and their proximity to the core European markets is a key locational advantage. It will enable us to supply our European customers with premium commercial vehicle tyres even more reliably and quickly, and to respond to their needs with the greatest possible flexibility.”

Ho Taek Lim, Vice President and Managing Director of the plant in Rácalmás, said, “This expansion project was one of the largest industrial development projects ever undertaken at the site in Hungary. The new truck and bus tyre production facilities will transform the plant into a comprehensive production site of significantly greater complexity and with a higher level of automation.”

Continental has expanded its global ultra-high-performance tyre portfolio, covering sizes 18 inches and above, over five years and plans further growth. By late 2027, it will add over 650 new sizes across all lines for original equipment and replacement markets. This responds to demand for tyres suited to larger, heavier, more powerful and electrified vehicles, supporting profitable growth.

UHP tyres for passenger cars and light commercial vehicles now matter more to Continental and its customers. From 2020 to 2025, their share of global passenger-car tyre sales across all brands rose from 41 to 55 percent. Asia-Pacific leads at 70 percent, the Americas at 66 percent and EMEA at 43 percent. For the Continental brand, the share grew from about 49 to 62 percent.

The trend towards larger tyres links to vehicle market shifts. Cars are becoming bigger, heavier and more powerful, with SUVs increasingly common. Electric mobility is another weight driver, since batteries add considerable mass. Modern drivetrains also produce torque once associated only with high-performance sports cars. These changes demand more from tyres, which must support heavier loads while ensuring safety, efficiency and comfort.

UHP tyres combine high grip, short braking distances and precise handling with low rolling resistance and high mileage. Continental develops them mainly for wheel-and-tyre combinations of 18 inches and above, performance SUVs, premium sedans, sports cars and high-performance electric vehicles. It is expanding this range across major markets, adding over 650 sizes by the end of 2027, including secondary brands such as Semperit and Uniroyal.

This reflects growing vehicle market diversification, as manufacturers offer more variants and need tyres tailored to differing performance, efficiency and comfort requirements. UHP tyres must meet conflicting demands, balancing grip, braking, handling, rolling resistance, comfort and mileage, with rubber compounds playing a central role. Continental relies on simulations, laboratory analyses, bench tests and driving tests across varied conditions, with the High Performance Technology Center in Korbach driving manufacturing advances applied globally, where UHP tyres up to 24 inches are made.

Testing occurs at the Contidrom near Hannover, Arvidsjaur in Sweden and Uvalde in Texas, focusing on braking, handling, high-speed capability, comfort and durability. Collaboration with tuners ABT Sportsline and BRABUS, plus motorsport input through Hoosier, further advances development. The SportContact 7 exemplifies the segment, available from 18 to 24 inches and approved by Audi, BMW, BYD, Maserati, Mercedes-Benz, Polestar, Porsche, Volkswagen and Zeekr, ranking top three in 27 of 29 international tests.

Edwin Goudswaard, head of Research and Development for Continental’s Tires group sector, said, “With our expanded UHP portfolio, we are responding directly to the increasing demands of modern vehicles. This enables us to offer our customers around the world even more tailored solutions for safety, efficiency and driving dynamics. As modern tyres become larger, heavier and more powerful, tyres are becoming even more critical. They are no longer simply the vehicle’s connection to the road, but a key prerequisite for safety, efficiency and driving dynamics. The UHP segment clearly demonstrates how capable modern tyres need to be. The art lies in combining conflicting requirements at the highest level, and that is precisely what sets our tyres apart.”
