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.

TyreSafe, UK’s charity dedicated to raising tyre safety awareness, has joined forces with Sussex Police’s Road Safety Team to introduce a pioneering digital reference tool for frontline officers. The initiative equips police with immediate, device-accessible tyre safety data during roadside stops.

Developed as a local pilot, the application enables consistent vehicle examinations and improves driver communication regarding tyre dangers. It offers specific checklists for diverse vehicle categories, including motorcycles, cars, heavy goods vehicles, light commercial vans and towed trailers. The system further incorporates guidance on part-worn tyres, common queries and educational talking points.

Following its Sussex trial, the programme holds potential for nationwide adoption across UK police forces. This deployment underscores Sussex Police’s dedication to roadway innovation and reinforces the essential contribution of proper tyre maintenance to overall public safety.

Stuart Lovatt, TyreSafe Chair, said, “This partnership with Sussex Police is a landmark moment for tyre safety enforcement and education. By putting reliable, accessible tyre safety guidance directly into the hands of frontline officers, we can ensure safer vehicles on our roads and help prevent avoidable collisions and breakdowns. Sussex is leading the way, and we hope this model will soon be adopted nationally.”

Superintendent Jo Grantham, Head of Roads Policing, Sussex Police, said, “Our officers are committed to keeping road users safe, and having instant access to this tyre safety resource makes a real difference on the ground. It supports enforcement while also giving us the tools to educate drivers more effectively. We’re proud to be working with TyreSafe on this project and to be the first police force in the country to pilot it.”

The UK Towing Safety Alliance (UKTSA) has published a comprehensive four-year analysis of incident data from National Highways’ Strategic Road Network, covering 2022 to 2025. The findings reveal a 23 percent rise in total towing-related incidents, driven primarily by a maintenance crisis affecting utility and commercial trailers. While traffic collisions involving towed vehicles decreased by 17 percent, mechanical breakdowns now constitute 77 percent of all towing-related incidents, highlighting vehicle and trailer condition as the sector's foremost challenge.

The data coincides with SMMT Motorparc 2025 figures showing Britain's vehicle fleet at its oldest recorded level, with average car age reaching 9.7 years. The summer harvest season has also arrived, bringing agricultural trailers back to roads after months of disuse. NFU Mutual research indicates collisions involving agricultural vehicles are 56 percent more likely between May and September, reinforcing the need for pre-journey roadworthiness checks.

Utility and agricultural trailers now account for nearly half of all towing-related callouts, surpassing 3,000 incidents in 2025. Regionally, the North West has overtaken the South East as the most incident-prone area, with trailer failures surging 60 percent since 2022, while the North East recorded a 55 percent increase. A growing divide exists between leisure and commercial towing sectors.

Leisure sector improvements, including fewer horsebox incidents and regional caravan reductions, suggest awareness campaigns are yielding positive results. However, utility trailer failures continue climbing, indicating maintenance standards across commercial and domestic sectors require greater attention. Regular servicing, correct loading and proper coupling remain essential to prevent avoidable incidents.

For working trailers, summer represents peak operational period, with agricultural and utility trailers seeing intensive use while rural roads become busier with tourists and cyclists. The Alliance emphasises that trailers stored for extended periods require thorough inspections before returning to service.

The UKTSA urges all towers to perform three essential checks covering tyres, load and connection before every journey. Tyres must be inspected for pressure, tread and deterioration; loads correctly distributed and couplings and electrical connections verified. The Alliance will place ‘The Working Trailer’ at the centre of safety campaigns, collaborating with industry partners to boost maintenance awareness and reduce preventable breakdowns across the Strategic Road Network.

A spokesperson for the UK Towing Safety Alliance said, “It’s encouraging to see fewer collisions involving towing vehicles, which suggests that drivers are becoming more aware of safe towing practices. However, that progress is being undermined by a growing number of preventable mechanical failures. The challenge is no longer simply about how people tow – it’s increasingly about what they’re towing and the condition it’s in. As both tow vehicles and trailers get older, regular maintenance has never been more important.”

Stuart Lovatt, Chair of TyreSafe, said, “Harvest season places extra demands on both vehicles and trailers, particularly those that may only be used for a few months each year. One of the most common issues we see is tyres that appear to have plenty of tread but have deteriorated through age, weathering or prolonged storage. Whether you’re towing a livestock trailer, plant trailer, horsebox or caravan, tyres should always be inspected for correct pressure, damage, cracking and signs of ageing before every journey. A few minutes spent carrying out these checks can prevent breakdowns and significantly improve safety for everyone using our roads.”

Sarah Smithurst MBE, COO, National Trailer & Towing Association (NTTA), said, “Across the NTTA network, we’re seeing a noticeable increase in enquiries from people looking to refurbish older trailers or source second-hand trailers, including imported models, as a more affordable alternative to buying new. While extending the life of a trailer is often entirely appropriate, it’s essential that owners understand that trailers are not maintenance-free. Many have been in service for years, sometimes decades, and components naturally deteriorate over time, even if the trailer has seen relatively little use. Every trailer should be thoroughly inspected before it returns to the road, with particular attention paid to tyres, brakes, bearings, couplings and lighting. Investing in regular servicing and maintenance is far less costly than experiencing a breakdown – or worse, being involved in an incident. The NTTA continues to help and advice new and old trailer users about safety and many are asking for help when towing, especially the reversing aspect of a trailer, now the B&E test was withdrawn. We are also seeing more trailers being repatriated from North America and Europe rather than purchasing new in the UK.”

JK Tyre & Industries has increased product prices and signalled further hikes as it seeks to offset rising raw material costs, even as demand remains resilient across segments.

The company said raw material prices rose about 20 percent quarter on quarter, with a further 8–10 percent increase expected in the following quarter. The increase has put pressure on margins, given that about 70 percent of tyre industry inputs are petro-based.

In response, JK Tyre raised product prices by 10–11 percent until August and plans an additional increase of 5–6 percent in the coming months to mitigate cost pressures.

The pricing action comes despite steady demand conditions. The company reported a 25 percent year-on-year increase in domestic volumes in the June quarter, supported by growth across both replacement and original equipment manufacturer segments.

Management indicated that demand remained stable across commercial vehicles, passenger vehicles and two- and three-wheelers, with no significant production cuts from OEM customers.

The company also said it continues to focus on premiumisation, with higher-margin products such as 16-inch and above passenger car tyres increasing their share in the sales mix.

Yokohama Rubber reported record earnings for the first half of fiscal 2026, with profits more than doubling and margins reaching a historic high.

The Japanese tyre maker said sales revenue rose 10.4 percent year on year to ¥639.4 billion in the six months to June, while business profit increased 54.3 percent to ¥95.8 billion. Operating profit doubled to ¥109.7 billion, and profit attributable to owners of the parent rose 104.2 percent to ¥72.6 billion.

Business profit margin improved to 15.0 percent, compared with 10.7 percent a year earlier, marking a record level for the company.

Yokohama Rubber said the results reflected strong performance across its businesses, delivering record first-half highs in all key earnings categories.

Segment data showed that tyre sales revenue rose 10.8 percent year on year to ¥580.4 billion, accounting for 90.8 percent of total revenue, while the MB (Multiple Businesses) segment recorded revenue of ¥54.9, up 6.9 percent and contributing 8.6 percent of the total. Other businesses declined 3.6 percent to ¥4.2 billion.

Business profit growth was led by the tyre segment, where profit increased 57.3 percent to ¥89 billion. The MB segment posted profit of ¥6.3 billion, up 22.5 percent, while other businesses reported profit of ¥0.5 billion.

The company said tyre segment growth was supported by higher sales of high-value-added and high-inch tyres, as well as increased volumes in the off-highway tyre business. Replacement tyre demand strengthened across regions, with strong sales in Europe and continued expansion in North America.

Operating profit was also supported by a ¥35.3 billion gain on the sale of assets at a former off-highway tyre plant in Israel, partly offset by a one-off expense of ¥15.0 billion related to the closure of a US tyre plant in Salem, Virginia.

The company also revised upwards its full-year forecast for fiscal 2026. It now expects sales revenue of ¥1,320 billion, business profit of ¥192.5 billion, operating profit of ¥199.5 billion and profit attributable to owners of the parent of ¥117 billion.
