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.

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.

Doublestar Tire has cemented its regional ambitions with the HEADWAY tyre series launch in Phnom Penh, where Chen Gang, Chairman of Doublestar (Cambodia) Factory, joined Deng Ling, General Manager of the Overseas Development Department and Xie Tao, Asia-Pacific Regional Director, to court local dealers and distribution partners. The Cambodian manufacturing base emerged as the centrepiece of the strategy, offering logistical agility and cost advantages that the company believes will underpin sustained growth throughout Southeast Asia. Executives used the gathering to reaffirm their commitment to tailoring products specifically for the Kingdom's road environment.

Engineering innovation took precedence as Xie Tao presented the HH316 passenger tyre, whose grooved architecture enhances wet-braking performance amid Cambodia's heavy seasonal rains, while five-pitch sequencing curbs cabin noise for a smoother ride. His counterpart Deng Ling outlined the brand's localised production philosophy, emphasising rigorous heat-reduction measures that extend tread life – a critical factor in tropical climates. The HU906 sports variant, engineered to rival premium benchmarks, rounded out a portfolio designed for both everyday commuters and performance-driven motorists.

The event also underscored the strategic value of the local partner, a 30-year industry veteran with nationwide reach, which has already invested heavily in promotional campaigns to elevate HEADWAY's profile. Distribution teams expressed enthusiasm for the product pipeline, while Chen Gang acknowledged their indispensable role in navigating Cambodia's fragmented retail landscape.

By merging domestic production with targeted product development and a seasoned ally, Doublestar signalled its intent to transform HEADWAY into a dominant local franchise, earning tangible buy-in from attendees who witnessed the brand's technological and commercial pitch firsthand.

KENDA Europe has completed the relocation of its Belgian operations from Arendonk to Turnhout, with the new facility becoming fully operational in March 2026. Constructed by the Bolckmans Group, the 8,000-square-metre centre occupies a strategically central location designed to enhance regional service efficiency while actively reducing CO₂ emissions. This site joins KENDA’s network of five other European locations that deliver fitting, distribution and sales support close to customers.

The Turnhout logistics hub features nearly 6,800 square metres of warehouse space alongside a 1,500-square-metre fitting area. Equipped with two semi-automatic assembly lines and eight fitting stations capable of handling tyres from 3 to 17 inches, the centre streamlines workflows to ensure consistent and reliable service delivery.

Sustainability was a core design principle beyond operational performance. Bolckmans utilised lower-carbon materials such as CEM III B concrete and XCarb steel, while glulam timber beams actively store carbon within the structure. Energy efficiency is achieved through advanced insulation, solar-control glazing, heat pumps and intelligent building management systems, complemented by rooftop solar panels and an on-site wind turbine that supply 100 percent renewable power. Rainwater harvesting and on-site infiltration systems further manage water resources.

With this new Turnhout base, KENDA reinforces its commitment to efficient operations and responsible practices, ensuring robust infrastructure to support customers both now and in the future.

Richard Todd, COO, KENDA Europe, said, “The move not only improves the way we work today but also gives us the flexibility to support our customers well into the future. Throughout the relocation, maintaining a high level of service was our priority, and I am pleased that the transition was completed smoothly.”

Bridgestone Americas has unveiled the second cohort of its national adaptive sports grant initiative, channelling USD 200,000 through Bridgestone Americas Trust Fund to eight school districts and nonprofit organisations. This latest allocation, consisting of eight grants valued at USD 25,000 each, is set to enhance athletic opportunities for 1,439 students across 75 public schools.

Despite over seven million public school students receiving special education services, participation in school athletics remains markedly low due to a shortage of adaptive programme resources. Bridgestone’s financial commitment directly confronts this disparity by bolstering both nascent and established K–12 sports offerings.
