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.

The Kari Motor Speedway witnessed a thrilling conclusion to the 28th JK Tyre FMSCI National Racing Championship, crowning a host of new champions across multiple categories. In the premier LGB Formula 4 class, Dhruvh Goswami of MSport staged a remarkable comeback to seize the title. The 18-year-old from Bengaluru, who began the final round trailing in the standings, dominated the weekend by winning three out of four races. His championship-winning performance was highlighted in the final 20-lap race, where he started seventh on a reverse grid but demonstrated strategic patience and skill, overtaking rivals including former champion Diljith TS and his own teammate, Ruhaan Alva, to claim a decisive victory. Monith Kumaran Srinivasan from Ahura Racing was awarded the Rookie title in the same category.

The event also featured the FIA-certified Formula 4 Indian Championship, where South Africa’s Luviwe Sambudla secured his first season win with a commanding pole-to-finish drive in the opening race. The podium saw international talent shine, with Ghazi Motlekar of Mozambique taking second and India’s Ishaan Madesh clinching third after a late overtake. In the subsequent race, Kenya’s Shane Chandaria claimed the win from pole position, followed by Motlekar in second and France’s Sachel Rotge in third.

In the two-wheeled action of the Royal Enfield Continental GT Cup, Anish Shetty from Bengaluru capped off his dominant season with another victory, having already secured the professional category title the previous day. The amateur class crown was claimed by Pondicherry’s Bryan Nicholas.

The championship also celebrated winners in its newer and entry-level series. Balaji Raju secured the Rookie crown in the debut JK Tyre Levitas Cup by winning both of the day's races, while Coimbatore’s Jai Prashanth Venkat dominated the Gentlemen category. The JK Tyre Novice Cup provided a dramatic finale, with Lokithlingeash Ravi of Pollachi emerging victorious in a tense season-ending shootout to claim the championship honours.

This year-round partnership creates a continuous and engaging touchpoint, directly connecting the YOKOHAMA brand with the passionate global community of ATP fans.

A new trans-Tasman alliance has been formed to fundamentally reshape the approach to end-of-life tyres in Australia and New Zealand. The Trans-Tasman Tyre Recycling Alliance (TTRA), a joint initiative of Tyre Stewardship Australia (TSA) and Tyrewise New Zealand, will function as an independent entity dedicated to advancing a circular economy for the sector. This collaboration arrives at a critical moment, as the two nations collectively discard more than 600,000 tonnes of tyres annually, presenting a significant environmental and economic challenge.

The urgency for such an alliance is underscored by recent data. In Australia, a mere 30,000 tonnes of end-of-life tyres are currently recycled domestically, leading to an estimated annual loss of over USD 50 million in resource value from large off-the-road tyres alone. Furthermore, a substantial portion of tyres in both countries are used for energy recovery rather than being transformed into valuable materials, highlighting a widespread missed opportunity for higher-value recovery. The TTRA will specifically champion advanced material applications, moving beyond this status quo to promote the use of crumb rubber in road construction, advanced manufacturing and innovative new products.

The alliance’s strategy is built upon five interconnected pillars: fostering technology and innovation, developing new markets for tyre-derived products, advocating for supportive policy and procurement standards, facilitating knowledge exchange across the industry and establishing a unified regional voice in global forums. This formal partnership allows both nations to leverage their distinct experiences; New Zealand can learn from Australia's more developed recycling markets, while Australia can gain insights from New Zealand's implementation of a regulated, mandatory stewardship scheme.

Scheduled to commence full operations in early 2026, the TTRA will not replace the existing national schemes but will instead operate alongside them, with both TSA and Tyrewise contributing resources and expertise. The formation of the alliance follows a successful global industry summit and signals a concerted effort to elevate industry standards, drive investment and create a more sustainable future for tyre management across the Australasian region and eventually into the Pacific.

Lina Goodman, CEO, Tyre Stewardship Australia, said, "We must work together across borders to unlock the full potential of circular tyre recovery and build resilience against global market disruptions. Through TTRA, we can get ahead of risks, capitalise on opportunities and accelerate the development of local markets for tyre-derived materials. The formation of TTRA reflects growing momentum behind product stewardship, circular economy outcomes and government mandates on recycled content, particularly in infrastructure projects.”

Adele Rose, CEO of 3R Group which manages New Zealand’s Tyrewise scheme, said, "Tyrewise has demonstrated how quickly a regulated system can deliver high collection rates and meaningful recovery outcomes. Through TTRA, we can not only share our learnings but can also be the incubator for new technology that demonstrates how a regulated well-supported scheme can foster greater circular outcomes. In addition, this assists us to support our close pacific neighbours who receive new and used tyres from our respective countries, often without the resources to manage those tyres when they become end of life. This is about building resilient, circular economies that support jobs, innovation and environmental responsibility. The future of tyre recycling in our region depends on the kind of collaboration TTRA represents."

A new, comprehensive national campaign is underway to address the critical issue of tyre safety within UK fleets. Spearheaded by TyreSafe, the UK’s charity dedicated to raising tyre safety awareness, this six-week educational initiative is founded upon three specialised toolkits developed in collaboration with industry leaders Driving for Better Business (DfBB), FORS and Lancashire County Council. This represents the most extensive suite of business-focused tyre safety resources the organisation has ever released, aiming to help companies strengthen compliance, enhance driver safety and achieve significant operational cost savings.

The campaign seeks to reframe tyre maintenance from a purely technical concern to a core business priority with profound implications. Neglected tyres present a major safety hazard, contributing to a heightened risk of collisions. Alarmingly, government data reveals that in 2024, 29 percent of all road fatalities occurred in incidents involving someone driving for work. Beyond the human cost, poorly maintained tyres have a direct financial and environmental impact; they waste fuel, increase emissions and lead to premature wear. This is particularly concerning given that transport remains a primary source of UK greenhouse gas emissions. Research underscores the scale of the problem, indicating that a majority of tyres on UK roads are underinflated and a significant number of vehicles are operating with at least one dangerous tyre.

To provide practical solutions, the three new toolkits offer step-by-step guidance and editable resources for seamless implementation. Developed with DfBB, the Grey Fleet Toolkit assists employers in managing the safety of employee-owned vehicles used for business purposes. In partnership with FORS, the Fleet Tyre Management Toolkit helps companies embed industry best practices for tyre procurement, inspection and maintenance. Finally, the Fleet Service Manager Toolkit, created with Lancashire County Council, provides fleet leaders and workshop managers with the materials needed to integrate tyre safety into staff training and daily operational checks. This broader effort by TyreSafe encourages businesses to view proper tyre care through the interconnected lenses of legal compliance, financial cost and carbon footprint, demonstrating how correct maintenance simultaneously reduces risk, saves money and supports sustainability targets. All resources are now available on the TyreSafe website.

Stuart Lovatt, TyreSafe Chair, said, “Tyre safety is not just about maintenance – it’s about responsibility. Every underinflated or worn tyre adds to a business’s costs, carbon footprint and legal exposure. Through these new toolkits and our six-week education campaign, we want to help fleets of every size understand that tyre safety is a measurable way to protect lives, budgets and reputations. Lancashire County Council’s partnership shows how tyre safety can be woven into daily operations, not added as an afterthought. By embedding simple checks into training and supervision, fleet teams can prevent incidents before they happen. Tyres are often missed during daily checks but one of the biggest influences on safety. We urge business drivers and fleet managers to ACT to ensure sound tyre safety management is included in their fleet policies which can make every journey safer, more efficient and sustainable.”

Simon Turner, Engagement Manager, DfBB, said, “Grey fleet drivers represent a hidden risk for many employers. This toolkit helps organisations bring them into the same safety and compliance framework as company drivers – meeting legal obligations and protecting everyone on the road.”

Daniel Fisher, Fleet Services Manager, Lancashire County Council, said, “Partnering with TyreSafe has allowed us to leverage our fleet management experience to provide practical guidance for others. The Fleet Service Manager Toolkit shows how simple, consistent tyre checks can improve compliance, cut costs and keep drivers safer. It’s a model that any organisation – public or private – can adopt.”
