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.

TYRESYSTEM, functioning as the digital arm of AZuR partner RSU, has made Tyre Pressure Monitoring System (TPMS) its central pillar of expertise. This unit moves beyond simple product sales by offering specialised training focused on tyre pressure monitoring systems. Their inventory is substantial, featuring over 500 sensors designed to accommodate a wide spectrum of vehicle types, and this hardware is supported by complementary valves, service kits and diagnostic programming tools.

The importance of this focus became legally binding on 1 November 2014, when TPMS became mandatory for cars, motorhomes and off-road vehicles. For workshop operators, a neglected sensor is a serious liability, as it not only creates a safety hazard but also guarantees a failed roadworthiness test like the TÜV. Consequently, the seasonal tyre change has evolved into a critical checkpoint where technicians must rigorously inspect sensor batteries and overall condition to ensure compliance.

To address this industry need, TYRESYSTEM acts as a holistic online wholesaler for tyres, rims and complete wheels. Recognising that hardware alone is insufficient, they established the TyreSystem Academy to deliver practical TPMS training through both online and on-site courses. This educational push helps workshops master modern tyre complexity. Correctly maintained TPMS systems preserve optimal pressure, reduce tread wear and extend tyre life, directly supporting resource conservation and a functioning tyre circular economy within the AZuR network.

Parcours, a British wheel brand specialising in aerodynamic, wind-tunnel-tested carbon wheelsets for road, gravel and triathlon cycling, has launched the Strade GT, the debut model in its new GT Series. At the heart of this wheelset lies VibraCORE, a technology developed alongside Lineat and Nottingham Trent University. VibraCORE embeds Lineat’s reclaimed aligned carbon fibre material, known as AFFT, directly into the rim’s spoke bed. This structural integration reduces vibration at its source rather than simply damping it after transmission begins.

The principle behind VibraCORE is straightforward: less vibration reaching the rider means less fatigue, allowing for longer, faster rides. Not all vibrations affect the body equally. Certain frequencies are either amplified by the human body or directly contribute to muscle exhaustion. VibraCORE targets these specific ranges, absorbing and dissipating vibrational energy before it travels through the wheelset to the rider. This approach directly addresses the harsh, high-frequency ‘road buzz’ that makes rough roads particularly draining.

In practical testing at standard road tyre pressures, VibraCORE reduces root mean square vibrational energy by an amount equivalent to lowering tyre pressure by roughly 10 to 15 psi. Crucially, this benefit comes without the usual penalties of softer tyres, such as reduced rolling efficiency or compromised handling precision. As a result, the Strade GT delivers a calmer, more controlled ride over long distances while retaining the stiffness, responsiveness and aerodynamic performance expected from a high-end wheelset.

To verify these claims, Parcours partnered again with Nottingham Trent University for controlled real‑world testing across multiple riders and surfaces. Using vibration sensors and frequency domain analysis based on power spectral density, the data showed that rims with VibraCORE reduced vibration energy by 19 to 23 percent compared to identical rims without the technology. This translates directly into a noticeably smoother ride on rough terrain and lower cumulative fatigue over extended rides.

Beyond comfort, the Strade GT represents an evolution of Parcours’ existing Strade platform. Its rim profile is optimised around a 30‑mm tyre, outperforming the previous model by 3.2W at 48 kmph, improving handling stability by 15 percent and achieving a weight of just 1,130g. VibraCORE also enables the use of lightweight Alpina Carbolite carbon spokes. Although sustainability is not the primary goal, the technology incorporates recycled carbon from Lineat’s AFFT process. Parcours is now developing a full circular pathway so that carbon recovered from old wheels, including those from its Crash Replacement Programme, can be reprocessed into VibraCORE components for future wheelsets. In this way, the Strade GT proves that speed and comfort need not be opposing forces.

Continental is celebrating two decades of its Camaçari tyre factory, situated near Salvador in Brazil. This occasion represents a major milestone for the firm’s operations throughout the Americas, as the site has served as a trusted partner across South America since its April 2006 opening. The facility supplies both replacement tyres and original equipment manufacturers with high-grade products for passenger cars and commercial vehicles.

Approximately 136 million tyres have rolled off the line at Camaçari over the last 20 years. Roughly BRL 1.2 billion (approximately EUR 235 million), has been invested there in the past 10 years alone to sharpen competitiveness through better efficiency, product quality and responsiveness to customers. The factory currently provides jobs for around 2,000 people, making it a leading industrial employer locally, with its future success built on team spirit, consistent quality and a strong customer focus.

The site began as a greenfield project in 2004 and was formally inaugurated in April 2006, with the first tyre, a ContiEcoContact 3, produced five months earlier in November 2005. Today, the factory supplies original equipment to major automotive names including General Motors, Volkswagen, Renault, Honda, Fiat and Mercedes‑Benz, proving its dependable and uniform product standards. This same drive for steady improvement supports the plant’s role in Continental’s wider environmental goals.

By constantly tracking energy use and managing it responsibly, the Camaçari plant ensures that all power generated or consumed on site is used as efficiently as possible. The facility relies entirely on LED lighting, which saves more energy than conventional options, and has carried out targeted production upgrades such as better insulation on critical machinery. These efforts have yielded annual energy savings, including a total cut of 10.4 gigawatt‑hours in 2025, equal to about five percent of the plant’s yearly energy consumption.

Shander Basílio, plant manager of the Continental tyre plant in Camaçari, said, "Our 20-year journey in Camaçari is a story of continuous growth, operational excellence and the deep commitment of our people to this region. I would like to sincerely thank all our employees for their outstanding contribution as well as to our customers for their continued trust. Looking ahead, we are dedicated to writing the next chapter of our plant’s success.”

Rodrigo Bonilha, head of Continental Tires South America, said, “I would like to congratulate our manufacturing team in Camaçari on their 20th anniversary. The production facility is a key asset for our business in the region. By manufacturing premium tires locally, we ensure a reliable supply for the Brazilian market while securing valuable local jobs. This ‘in the market, for the market’ approach is fundamental to how we deliver consistent product quality and performance for customers and consumers.”

The Tire Industry Project (TIP) has announced the publication of a scientific study presenting a sophisticated model designed to track how tyre and road wear particles (TRWP) move through land and freshwater environments. Known as the Mass Balance Model, this tool provides a method for predicting particle concentrations within watersheds across different climates and regions, offering high spatial detail on how these particles travel from roadways towards rivers, lakes and estuaries.

Tyre and road wear particles are created unintentionally during normal driving, where tyres meet the road surface. As scientific and regulatory focus on these particles intensifies, reliable models are essential for understanding their environmental pathways. While research is growing, the behaviour of these particles in waterways remains particularly understudied, making this modelling advance especially relevant.

The model draws on global and local datasets and open-source frameworks, including the ERA5 global climate dataset by the Copernicus Climate Change Service and the Wflow catchment hydrology model by Deltares, a research institute. Its accuracy has been confirmed using field measurements from the Seine River basin in France, the Chesapeake Bay basin in the United States and the Yodo River basin in Japan – three very different watersheds. This validation shows the approach works across diverse watershed sizes, climates and stormwater management systems.

Applying the model to these three regions revealed that the share of particles reaching surface waters varies from just 2 percent up to 18 percent, depending on urbanisation, climate, basin size and drainage infrastructure. Importantly, improvements to stormwater systems could cut particle transport to surface waters by as much as half. This refined model builds on earlier work and is now globally applicable, with ongoing development aimed at making it accessible beyond the scientific community.

Nicolas Tissier, Director of Research at TIP, said, “Having a robust, reproducible model for TRWP transport and fate that can be applied worldwide is essential for advancing both scientific understanding and practical solutions. Our role at TIP is to support rigorous, transparent science that helps researchers, policymakers and industry make evidence-based decisions. By making this model open access, we aim to support broader collaboration across the scientific community around TRWP in the environment and to enable the development of more effective mitigation strategies.”
