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.

American tyre brand General Tire is marking 111 years since its founding on 29 September 1915, when William O’Neil and Winfred Fouse established the General Tire and Rubber Company in Akron, Ohio. What started as a regional tyre maker has evolved into an internationally recognised brand, especially noted for durable tyres suited to SUVs, off-road vehicles and pickups. Since 1987, the company has operated as part of Continental.

The brand’s history tracks closely with the growth of the North American automotive sector. During the 1920s, General Tire earned attention for its ‘General Balloon Jumbos’, which helped push tyre technology forward. As operations grew, the company widened its international reach and became a supplier to major vehicle manufacturers.

William O'Neil, Founder of General Tire

General Tire and Continental first connected in March 1949 through a cooperation agreement covering the exchange of technical expertise and know-how. By the late 1950s, General Tire had opened a tyre testing facility in Uvalde, Texas, then regarded as the largest of its kind worldwide. Continental’s 1987 acquisition opened a new chapter, giving the parent company a global production and sales network for the first time while allowing General Tire to pair its American heritage with worldwide development and manufacturing strength.

Today, the portfolio spans applications from the Grabber GT Plus road tyre and Grabber Cross A/S all-season tyre to the Snow Grabber Plus winter tyre and the Grabber AT3 Plus and Grabber X3 off-road models, all reflecting performance, reliability and American heritage. For the anniversary, General Tire introduced the next-generation Grabber AT3 Plus, an all-terrain successor to the Grabber AT3 with better snow traction, improved wet-road grip and a tread pattern built for demanding off-road use.

Dunlop Motorcycle Europe is set to support a star-studded rider roster at this weekend’s FIM Motocross of Nations (MXoN) in Ernée, France, aiming to cap another standout motocross season. The tyre range available to competitors includes the sand-focused Geomax MX14 for loose surfaces, the intermediate Geomax MX34 and the Geomax MX54, which has become the preferred choice across a wide range of intermediate and hardpack tracks.

The company will supply tyres to 32 riders representing 16 nations, drawing talent from the FIM Motocross World Championship, North America’s Supercross and Pro Motocross series and other competitions. The event follows last weekend’s season-ending MXGP of Australia, with many of the sport’s top names returning to action in pursuit of the Chamberlain Trophy.

Dunlop has built a formidable recent record at the MXoN, having equipped riders from every winning nation over the past four editions. Team Australia took consecutive victories in 2024 and 2025, Team France claimed the title in 2023 and Team USA won in 2022. This year, Australia arrives with an entirely new lineup in Jed Beaton, Alex Larwood and Aaron Tanti, while the United States fields an all-Dunlop trio led by three-time 450 cc AMA Supercross champion Cooper Webb, joined by Julien Beaumer and Levi Kitchen.

For France, MXGP runner-up Romain Febvre spearheads the Dunlop contingent and is joined by fellow Kawasaki Racing Team rider Mathis Valin. Two-time MXGP World Champion Jorge Prado will represent Spain alongside newly crowned MX2 World Champion Guillem Farres. A host of other leading MXGP and MX2 competitors will also run Dunlop, including Camden McLellan for South Africa, Liam Everts for Belgium, Pauls Jonass for Latvia and Jeremy Seewer for Switzerland.

The MXoN serves as a fitting finale to a season of significant success for Dunlop across European and North American series. In the United States, Ken Roczen captured his first 450 cc AMA Supercross title on Dunlop, extending the brand’s streak of winning every AMA Supercross and Pro Motocross championship since 2010.

In the FIM Motocross World Championship, Guillem Farres secured the MX2 crown and led Triumph Racing to a one-two finish with teammate Camden McLellan. The pair combined for 11 of 19 Grand Prix victories. In MXGP, Romain Febvre finished runner-up, while Kiara Fontanesi narrowly missed a historic seventh WMX title, winning at Foxhills in July and adding three second-place finishes.

Wim Van Achter, Motorcycle Motorsport Manager EMEA, Dunlop Motorcycle Europe, “The fact that so many top riders continue to choose Dunlop Geomax tyres underlines the Geomax range’s performance credentials. We work closely with top riders to develop new Geomax products, using their feedback to refine our tyre technology. Our most recent innovation, Geomax MX54, makes the Geomax range our strongest and most versatile motocross range yet, drawing on our knowledge from winning top professional championships. With its broader scope, it could be the tyre of choice for Ernée’s traditional hardpack clay circuit this weekend.”

Eddy Seel, MXGP Event Leader, Dunlop Motorcycle Europe, said, “We are honoured that Dunlop Geomax tyres are the products of choice for 32 of the world’s most talented riders representing 16 different nations. The level of competition is always high at MXoN, but Dunlop has a history of success. Our riders have already proven the performance and reliability of the Dunlop Geomax range all season long, so we’re ready to continue with that this weekend. Allez!”

TyreSafe, UK’s leading tyre safety charity, has launched its annual Tyre Safety Month by cautioning UK motorists that confidence in their vehicles’ stopping ability may be misplaced. Research indicates that although 83 percent of drivers feel fully in control of stopping distances, merely 6 percent know the additional distance required to halt in wet conditions at motorway speeds.

The study reveals that 94 percent of drivers underestimate how sharply stopping distances grow in rain, with many erring by substantial margins. This mismatch between perceived and actual risk spans every UK region, pointing to a nationwide problem involving driver awareness and vehicle preparedness.

In response, TyreSafe advises routine tyre checks, especially before seasonal shifts and heavier rainfall. Motorists are urged to remember the ACT principle – air pressure, condition and tread depth – and to act before they react.

Stuart Lovatt, Chairman, TyreSafe, said, “Many drivers and riders believe they are in control – but that confidence is often misplaced. Stopping distances in wet conditions can be far greater than expected, and tyres play a critical role in that equation. If your tyres are not properly maintained, your ability to stop safely is significantly reduced – no matter how confident you feel behind the wheel.”

Scandinavian Enviro Systems AB (publ) has secured a second extension of its company reorganisation, with the Gothenburg District Court approving a further three-month period lasting until 27 November 2026. The company has been under reorganisation since 27 February 2026, when the court initially granted the process. An earlier extension had already pushed the deadline to 27 August 2026 before this latest decision.

In its ruling, the District Court noted that Enviro has submitted a draft reconstruction plan and secured the necessary financing for it. The court also found that the company has taken other required measures, leading it to conclude that exceptional grounds exist to justify continuing the reorganisation beyond the ordinary timeframe.

Enviro now plans to ask the court to order plan negotiations and schedule a plan hearing as soon as possible. At that hearing, affected parties will be placed into groups and permitted to vote on whether to adopt the reorganisation plan. Details of the hearing date and participation instructions will be announced via press release and the company's website. Unless plan negotiations are ordered earlier, a reorganisation may last at most one year, or 15 months from the initial decision in such cases.

Fredrik Aaben, CEO, Enviro, said, "The District Court's decision gives us the opportunity to continue the intensive work of completing the company reorganisation. We have taken several important steps forward and are now working purposefully to establish a strong and long-term sustainable Scandinavian Enviro Systems. The strong interest in Enviro's technology persists, both with regard to licensing and other forms of collaboration. We are firmly committed to completing the reorganisation and building a strong industrial company based on our world-leading technology.”
