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 Tire Recycling Foundation (TRF) has officially announced the finalists for its first-ever Circle of Change Awards, a national programme designed to honour individuals, organisations and teams advancing tyre recycling and circular economy leadership. The winners are scheduled to be revealed on 14 May 2026, during the Tire Recycling Conference Awards Luncheon in Denver, Colorado. This year’s conference carries the theme ‘Tread Boldly: Advancing Tire Recycling Through Collective Innovation’.

The pool of finalists spans state-led programmes that have developed scalable and self-sustaining markets for recycled tyres, as well as engineering breakthroughs integrating tyre-derived materials into roads, stormwater systems and urban redevelopment projects. Collectively, these nine initiatives illustrate the expanding innovation and rising demand for tire-derived products across United States.

The awards are structured into four distinct categories, each addressing a critical component of tyre circularity. These include tyre recycling processes, the design and manufacturing of recycled materials, market development for those materials and the complete end-of-life tyre value chain. Together, the finalist projects underscore the creativity and positive momentum shaping the domestic recycled tyre industry.

In the Circular Economy Trailblazer Award category, Colorado and North Carolina were recognised. Colorado has utilised a waste tyre rebate programme and market-development grants to reduce stockpiles and illegal dumping while boosting demand for tyre-derived fuel and moulded products. North Carolina implemented a legislative model that stabilises upstream recycling reimbursements for counties and expands incentives for rubber-modified asphalt applications.

The Innovation in End-Use Technology Award features three honourees. Bolten & Menk constructed a stormwater best management practice system using 210,000 recycled tyres for the city of Woodbury, Minnesota. LHB Engineering and the St. Paul Port Authority applied 30,000 cubic yards of tyre-derived aggregate in underground stormwater retention to redevelop the former Midway Stadium brownfield site. Liberty Tire Recycling, partnering with Atlanta DOT, the University of Georgia, and The Ray, launched an asphalt heat-island pilot to improve pavement durability and study climate and equity benefits in an urban corridor.

For Market Development Excellence, the Alabama Department of Conservation and Natural Resources leveraged rubber-modified asphalt to resurface park roads and parking areas, creating consistent material demand. A Michigan multi-partner effort led by EGLE has scaled recycled tyre applications from pilot projects to hundreds of lane-miles through advanced specifications and coordinated research.

The Value Chain Collaboration Award recognised Bolder Industries and Pirelli Tire LLC for a traceable closed-loop system converting scrap tyres into certified recovered carbon black for new tyre production, alongside Phibro rCB for restarting an idle pyrolysis facility and qualifying recycled materials for tyre manufacturing. An independent panel of industry experts scores all entries based on innovation, measurable impact, scalability and category alignment, with honouree mentions possible at the judges’ discretion.

Stephanie Mull, Executive Director, Tire Recycling Foundation, said, “At the heart of tyre recycling is a simple but powerful challenge: reframe waste from an endpoint into a catalyst for societal value. This year’s nominees show how far we’ve come in turning end‑of‑life tyres into valuable materials that strengthen infrastructure, support communities and protect the environment and remind us that important work still lies ahead.”

Dick Gust, President, Tire Recycling Foundation Board, said, "The Circle of Change Awards recognise bold action and innovation. We honour the innovators, state leaders and collaborators demonstrating that tyre recycling unlocks real solutions and transformation. Each finalist exemplifies what’s possible when visionary action aligns with smart policy and sustained commitment.”

The Goodyear Tire & Rubber Company reported a net loss of USD 249 million for the first quarter of 2026, as weaker consumer demand and higher raw material costs weighed on performance across key markets.

The US tyre manufacturer posted net sales of USD 3.9 billion for the quarter, down from USD 4.3 billion a year earlier, while tyre unit volumes fell to 34 million from 38.5 million.

Goodyear reported a loss of USD 0.86 per share, compared with net income of USD 115 million, or USD 0.40 per share, in the same period last year. Adjusted net loss widened to USD 112 million from USD 11 million a year earlier.

“The first quarter reflected a challenging environment, marked by weak consumer industry demand in both OE and replacement across the majority of our key geographies,” said Mark Stewart, Chief Executive and President of Goodyear.

“Despite a weak environment, our first quarter results were in line with our expectations and reflect our commitment to drive value for our brands in the marketplace, where we offer world-class differentiated products and services.”

Stewart said rising raw material costs linked to the conflict in the Middle East and continued pressure on industry demand would require further action to strengthen the company’s cost structure.

Segment operating income fell to USD 95 million from USD 195 million a year earlier. The decline reflected lower volumes and inflationary pressures, partly offset by benefits from the company’s Goodyear Forward restructuring programme, favourable price and raw material mix, and a tariff-related adjustment.

The Americas business reported first-quarter sales of USD 2.1 billion, down 17.5 percent from the previous year. Replacement tyre volumes declined 23.2 percent amid weak market conditions in North America, increased promotional activity and the planned rationalisation of lower-tier products.

Segment operating income in the Americas fell to USD 37 million from USD 155 million a year earlier.

In Europe, the Middle East and Africa, net sales rose 6.7 percent to USD 1.4 billion, supported by currency movements and price mix, despite lower tyre volumes and the sale of the Dunlop brand. Segment operating income improved to USD 1 million from a loss of USD 5 million in the prior year.

Asia Pacific reported sales of USD 455 million, down 4 percent from a year earlier due to weaker original equipment demand in China. However, segment operating income rose to USD 57 million from USD 45 million, supported by pricing and restructuring benefits.

Goodyear said its Goodyear Forward transformation programme delivered USD 107 million in benefits during the quarter.

Continental has released a new White Paper titled ‘Enhancing Fleet Reliability Through Digital Tire Management – Safety by Continental’, which addresses how logistics companies across the European Union can reduce operational risks amid persistently high fuel costs and ongoing geopolitical uncertainty. For fleets operating cross-border and long-haul routes, volatile energy prices and tight delivery schedules leave little room for unexpected disruptions, prompting a closer look at tyre safety as a critical but often overlooked factor.

Under growing cost pressure, many logistics operators are reassessing areas where risks can still be actively managed. Vehicle safety, particularly the condition of tyres, is no longer seen solely as a compliance issue but as a direct influence on efficiency, uptime and cost control. Tyres affect stability, braking and fuel consumption, yet issues like pressure deviations and heat buildup can go unnoticed between manual inspections. When tyre problems arise on the road, they often result in breakdowns, delivery delays and expensive roadside repairs, which are especially damaging to EU-wide logistics operations.

The White Paper notes a significant shift among European fleets towards continuous, data-driven tyre safety strategies instead of reactive fixes. Digital monitoring systems are being adopted to detect risks early and integrate tyre condition into planned maintenance. Continental’s ContiConnect system is highlighted as a practical example, using in-tyre sensors to continuously track pressure and temperature. The system provides fleet-wide visibility and automated alerts when values exceed set thresholds, enabling timely intervention before tyre issues cause route incidents.

Real-world fleet experience cited in the White Paper shows that continuous tyre monitoring delivers measurable gains, including fewer tyre-related breakdowns, better fuel efficiency from optimised pressure and longer tyre life. For logistics operators working across multiple EU countries, these improvements lead to more predictable routes, fewer unplanned stops and greater delivery reliability. While fleets cannot control fuel prices or geopolitical events, the paper emphasises that safety-critical asset management remains within their control, making tyre safety a core part of operational risk management in a challenging environment.
