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:

• Technical support for restarting the HF Curing Presses

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.

Pirelli has announced a technical update for the Moto2 class ahead of the World Championship’s European season opener this weekend in Jerez de la Frontera, Spain. The Italian tyre manufacturer will supply riders with a new rear development tyre designated F0192. This specification shares the same structural design as the existing supersoft SCX but introduces an alternative compound aimed at enhancing wear resistance and delivering more consistent performance over race distances.

Following its initial rollout at the United States Grand Prix, the standard supersoft SCX remains available for this round, enabling Moto2 competitors to conduct a direct back‑to‑back comparison with the new compound variant. Both rear supersoft options may be paired with the standard soft SC1 and medium SC2 front tyres. With the addition of the development tyre, each intermediate class rider will have access to up to ten rear tyres across the weekend.

For the Moto3 category, the championship’s entry class will rely on proven, reliable solutions. Riders will use the soft SC1 and medium SC2 compounds for both front and rear positions. These specifications have a successful track record in Jerez, as demonstrated last year when José Antonio Rueda claimed victory with a medium SC2 front and a soft SC1 rear.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “On the occasion of the Spanish GP, scheduled for this weekend at the Circuito de Jerez - Ángel Nieto, we have decided to provide Moto2™ riders with a new rear development specification, the F0192. Compared to the standard supersoft SCX, it retains the same structure but features a new compound. This solution should improve wear while also delivering more consistent performance over race distance.

“The Jerez circuit is an excellent testing ground for evaluating new soft solutions, as it does not have highly abrasive asphalt and, at this time of year, temperatures are usually warm enough to allow the use of particularly soft options. In addition to this new solution, riders will of course also have access to the standard SCX, enabling a direct comparison between the two tyres under the same track and weather conditions, providing us with the most accurate feedback possible. The supersoft was already used as a race tyre last year and proved well suited to the characteristics of this circuit, so it is simply a matter of understanding which of the two alternatives will be preferred by the riders.”

The Tyre Recovery Association (TRA) has warned that UK’s circular economy goal will remain out of reach if waste tyre processing continues to move abroad. Environment Agency data shows enhanced verification measures introduced last October have a compliance rate below two percent, a figure the TRA described as deeply concerning. Without a fundamental shift in policy and enforcement, a closed-loop system cannot be realised.

Exporters are systematically ignoring the new rules. Of 4,189 waste tyre shipments since 1 October 2025, only 54 post-shipment forms were completed correctly, a compliance rate of just 1.3 percent. The vast majority of UK’s annual 300,000 tonnes of tyre exports end up at illegal batch pyrolysis plants in India. The TRA called this both an environmental failure and an economic loss, as the UK ships abroad the very feedstock needed to power its own circular economy.

While the UK treats waste tyres as a disposal problem, the domestic sector holds 150,000 tonnes of licensed but idle processing capacity. The TRA argued that with enforceable regulation and proper oversight, the industry could expand significantly, creating skilled jobs and generating high-value secondary materials at home instead of losing them overseas.

Shredding tyres reduces environmentally harmful disposal and unlocks new value streams. Shredded tyres are strategic feedstock for sustainable aviation fuel, advanced continuous pyrolysis, recovered carbon black for new tyre manufacturing and rubberised asphalt for long-life roads. The TRA urged immediate regulatory action to stop uncontrolled exports and activate dormant domestic processing capacity without further delay.

Peter Taylor OBE, Secretary General, Tyre Recovery Association, said, “The Environment Agency’s transparency is very welcome, but the figures are an indictment of those tyre export brokers who continue to operate without conscience. To see a compliance rate of just 1.3 percent is ultimately depressing, these measures are a long way off having any meaningful impact.

“New measures need to be introduced so that EA can fulfil their statutory duty; until then, the export chain simply continues to abuse their goodwill. We must face the hard reality. Shred is the only immediate route to a circular economy and sustainable future for British operators. Unless we mandate that tyres must be mechanically processed into shred before they leave our shores, we will continue to fuel pollution abroad while our domestic recycling assets wither.

“Our neighbours and competitors are realising the opportunity from secondary materials. We continue to export the UK’s future in the back of shipping containers, while the rest of the world builds a circular economy. If the UK does not move to a shred-only mandate, we will be left behind.”
