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 Association of Natural Rubber Producing Countries (ANRPC) has confirmed that its Annual Conference 2026 will take place on 23–24 November 2026 at the Pullman Pattaya Hotel G in Pattaya, Thailand. The gathering will adopt the theme ‘Building a Resilient, Competitive and Sustainable Global Natural Rubber Industry’, reflecting the sector’s urgent need to address mounting pressures across the global value chain.

The two-day programme will feature five thematic sessions before a moderated panel discussion. These sessions will cover geopolitics and the Middle East conflict, climate change and its effects on production and productivity, supply-demand dynamics and price volatility, advancing sustainability beyond the European Union Deforestation Regulation (EUDR) and the implications of protectionist policies for trade and consumption. A 40-minute High-Level Roundtable on the Future of the Global Natural Rubber Industry will close the conference, focusing on strategic priorities, collaborative action and practical pathways towards long-term resilience and growth.

The global natural rubber industry stands at a critical juncture, with rising temperatures, shifting rainfall patterns, flooding and climate-related diseases increasingly pressuring production and productivity. Geopolitical tensions, including the ongoing Middle East conflict, rising operating costs, narrowing margins and evolving sustainability requirements are adding further strain across the value chain, said the association.

As a renewable resource, natural rubber supports industrial development and sustainable value chains, yet it faces supply constraints, price volatility, declining productivity, tree diseases, rising costs and stringent ESG requirements. These challenges also present opportunities to strengthen competitiveness, enhance value addition, diversify markets and accelerate sustainable practices. With decarbonisation efforts advancing towards 2030 and regulations such as the EUDR reshaping market access, stakeholders must collaborate to build responsible, inclusive, transparent and viable supply chains. Innovation, investment, and sustainable finance will be vital for smallholders and SMEs, the association further added.

Max Verstappen completed a flawless weekend at the Marina Bay street circuit by winning the Singapore Grand Prix, adding Sunday’s race to his earlier Sprint victory and both pole positions. The Red Bull driver managed his Pirelli Soft and Medium compounds across a one-stop strategy while the tyre supplier’s rubber proved central to the race’s varying tactics.

Charles Leclerc finished second for Ferrari, with Kimi Antonelli third for Mercedes. The top three all began on Softs before switching to Mediums, but Leclerc and Antonelli exploited a Virtual Safety Car (VSC) period on lap 39 to fit fresh Softs for a second stop.

Verstappen, by contrast, ignored the VSC window, completing 32 laps on his starting Softs before moving to Mediums and running them to the flag. Only Soft and Medium compounds featured throughout the race.

Antonelli extended his championship lead to 340 points, helped by teammate George Russell’s ninth-place finish. Russell sits second on 238, with Lewis Hamilton third on 229. Russell also recorded the longest Medium stint at 39 laps, while Hamilton, sixth, ran 44 laps on a single set of Softs.

Dario Marrafuschi, Pirelli Motorsport Director, said, “As widely expected, regardless of the neutralisations, the one-stop strategy proved to be the most competitive, with the Soft-Medium combination emerging as the most effective option. The C5 was the star of the race, as it delivered very long stints while maintaining a strong level of performance and offering the advantage of greater grip than the other compounds available. Drivers who used it for around half the race only experienced a performance drop-off in the closing stages.

“The Hard tyre was not a strategically attractive option for the teams, as it offered less grip than the C4 which, despite being the softer compound, exhibited virtually no degradation, without providing any tangible advantages in a race already firmly geared towards a one-stop strategy. As a result, although the C3 has proven effective at other circuits, it was not selected by any driver in Singapore. Tyre degradation was in line with what we had already observed during free practice, and the visual condition of the tyres at the end of the stints was also very encouraging, even over the longest runs. Wear was manageable, although it required a degree of attention, particularly on the rear-right.”

The DUNLOP Group has systematically organised its sustainable natural rubber procurement initiatives for the first time, centring on the previously announced group-wide Sustainable Natural Rubber Subcommittee. The company will promote these initiatives and accelerate related activities. Natural rubber remains a key raw material for the group, and its production depends heavily on smallholder farmers, meaning challenges tied to productivity, income and environmental and social issues directly affect stable and sustainable procurement.

A second phase of the Sustainable Natural Rubber project, supporting smallholder farmers in Indonesia, began in April 2026. The project was originally launched in 2022 by Sumitomo Rubber Singapore Pte. Ltd., the group's natural rubber procurement subsidiary, together with PT. Hok Tong, a processing company owned by Halcyon Agri Corporation Ltd. In the first phase, improved productivity and earnings were confirmed for participating farmers. Phase 2 will continue support in Sumatra's Jambi region while extending coverage to Rantau Prapat in North Sumatra, aiming to assist roughly 1,740 farms cumulatively each year, with targets rising annually through April 2029.

During Phase 1, which ran from 2022 to 2025, more than 1,000 smallholder farmers in Jambi received support. Yields increased by up to about 19 percent, and both productivity and profitability improved in the project areas. In Phase 2, lessons from that experience will inform expansion into Rantau Prapat, where similar supply chain risks exist. Follow-up training will also continue in Jambi, with technical guidance and agricultural supplies provided so that improved techniques are fully adopted and yields rise further.

The group has identified and assessed its business activities' dependence on and impact upon natural capital, along with related risks and opportunities, following the Taskforce on Nature-related Financial Disclosures recommendations and the LEAP Approach, and has disclosed information accordingly. The newly established subcommittee has systematically categorized natural rubber risk mitigation measures using the Action Framework proposed by the Science Based Targets Network, linking identified risks and opportunities to business activities.

That framework organizes corporate actions addressing nature-related impacts into avoidance, reduction, restoration or regeneration and transformation. Through this structure, the group will clarify the roles of initiatives previously pursued separately, including risk assessment, farmer support and research and development, as well as measures needed going forward. The Farmer Support Project falls under the framework's reduction objective, with the aim of improving farmer productivity and profitability and thereby lowering risks in the natural rubber supply chain.

Phase 2 is scheduled to run from April 2026 to April 2029, covering Jambi and Rantau Prapat in Sumatra, Indonesia. Support targets 870 households in Jambi and 870 households in Rantau Prapat annually, delivered mainly through technical guidance and agricultural supply support. Indonesia ranks among the world's leading natural rubber producers, and Sumatra is one of its major production areas.

Dwi Sutrisno, Sustainability Manager, PT. Hok Tong Indonesia, said, “This Project is a valuable initiative that strengthens the knowledge, skills and capabilities of smallholder farmers while supporting higher productivity and more sustainable farming practices. As the implementing partner, PT. Hok Tong Indonesia is proud to contribute to this effort and to see the positive impact it brings to farmers and their communities.”
