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.

Titan International has introduced the Radial Trail A/T, a new all-terrain high-speed trailer (HST) tyre described as the first true product of its kind in the industry. Unlike conventional trailer tyres that are often adapted from older light truck designs, this model has been engineered entirely from the ground up as a dedicated trailer tyre capable of performing reliably across diverse environments. Alongside this launch, Titan has announced a speed-rating upgrade to its established Radial Trail HD tyre.

The new Radial Trail A/T tyre’s field-tested design incorporates an aggressive tread pattern for enhanced traction on gravel, mud, grass and uneven backroads. The tyre also features a centre tread bridge that lowers rolling resistance to support better fuel efficiency and towing stability. Shoulder tread bridges promote even wear and extend the tyre’s lifespan while reducing road noise, and an open shoulder configuration helps dissipate heat and shed debris. Alternating scoops improve control on soft surfaces such as sand and mud, and extended tread elements along with a rim guard offer added protection against scuffs and impacts. The Radial Trail A/T is currently available in size ST235/75R15 LRE, with four additional sizes expected to roll out over the summer.

Now carrying an N speed rating, which allows for operation at speeds up to 87 mph (approximately 140 kmph), the updated Radial Trail HD tyre incorporates heat-resistant engineering to deliver reliable performance under demanding conditions while surpassing Department of Transportation standards. The enhanced Radial Trail HD tyres are available for order immediately.

Both product releases reflect Titan’s continued focus on advancing trailer tyre technology through purpose-built solutions. Whether used for long highway journeys or off-road exploration, these tyres aim to provide drivers with improved traction, durability, and dependability. Together, they represent the company’s broader effort to support trailer owners with greater confidence and peace of mind on the road.

Ryan Fuller, High Speed Trailer Product Manager, Titan Specialty Division, said, “Titan is setting a new standard in high-speed trailer tyre performance. The Radial Trail A/T is the first trailer tyre truly engineered for all-terrain conditions, not adapted from outdated moulds. Combined with the enhancements to the Radial Trail HD, we’re giving our customers unmatched confidence whether they’re hauling down highways or navigating rugged backroads.”

Continental has once again been recognised as ‘Tire Manufacturer of the Year’ at the latest edition of Tire Technology International Awards for Innovation and Excellence, marking the fifth time it has received this prestigious honour. The independent jury acknowledged the company's groundbreaking tyre technologies, innovative measurement approaches and continuous production process enhancements for establishing new industry standards. Additionally, Continental received the ‘Environmental Achievement of the Year – Manufacturing’ award for its substantial progress in reducing water consumption during tyre production.

During the 3 March ceremony in Hannover, the jury specifically highlighted several key developments from Continental's 2025 initiatives. The company advanced sustainability through the adoption of renewable synthetic rubber components, including pyrolysis oil recovered from end-of-life tyres and recycled cooking oil. A collaborative effort with the Technical University of Braunschweig yielded an innovative method for detecting tyre wear particles using a specialised vacuum system positioned behind drive wheels, equipped with sensitive particle sensors capable of identifying even microscopic airborne debris from various vehicle locations.

The VanContact A/S Eco received special recognition as the first van tyre to achieve the highest ‘A’ rating across all three EU tire label categories – rolling resistance, wet grip and rolling noise. Continental's partnership with the Deutsche Gesellschaft für Internationale Zusammenarbeit promoting responsible natural rubber sourcing in Indonesia also earned jury commendation.

Between 2020 and 2025, Continental successfully reduced water withdrawal per metric tonne of product by over 10 percent across all production facilities, conserving an impressive 197 million litres of water. This achievement resulted from implementing advanced filtration and membrane technologies that enable approximately 90 percent of wastewater to be treated and reused. The company maintains a comprehensive water management approach, systematically refining processes related to heating, cooling and sanitation. External validation of these efforts came through a ‘B’ rating from the independent organisation CDP for Continental's 2025 water management practices.

Edwin Goudswaard, Head of Research and Development at Continental Tires, said, “Tyres are our passion. We are committed to optimising them and making our manufacturing processes even more advanced and resource-efficient. Our greatest strength is our global team, working together closely to develop highly creative and innovative solutions. The jury honoured this very special commitment. And I would like to express my heartfelt thanks to all our colleagues for their remarkable dedication.”

Henning Mühlenstedt, Head of Future Technologies and Sustainable Infrastructure at Continental Tires, said, “Water is a valuable resource. Our continued progress in reducing consumption at our plants demonstrates how effective our approach is.”
