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.

Pirelli has entered a three-year agreement with Netcompany INEOS, beginning in 2027, that will make the Milan-based manufacturer the Official Tyre Partner of one of professional cycling’s most prestigious teams. The partnership rests on a shared commitment to performance through innovation, technological progress and close attention to details capable of influencing final results.

Ahead of the collaboration, two Pirelli tyres underwent technical assessment. The PZERO RACE SL-R is a road tyre focused on aerodynamics and rolling efficiency, engineered to reduce aerodynamic drag and rolling resistance in fast racing and high-speed conditions. The PZERO RACE RS was developed to balance rolling efficiency, grip, protection and predictable cornering, giving riders confidence and stability across varied road surfaces, racing situations and weather.

The team’s bike, fitted with Pirelli tyres, is being displayed at the Pirelli stand during Rouleur Live in London from today until Saturday 14 November. The partnership will centre on developing and evaluating technical solutions suited to WorldTour cycling, where efficiency, reliability and performance must work together across conditions ranging from Grand Tours to the five Monuments.

Netcompany INEOS riders’ technical feedback will support product development and validation, with Pirelli technicians working alongside the team’s engineers and research and development management and integrating road data into outdoor testing protocols. The collaboration also reflects both organisations’ focus on marginal gains, with the tyre treated as a key part of the rider-and-bike system. Pirelli’s patented PAAS technologies are cited as helping address trade-offs such as rolling resistance versus grip. Pirelli tyres are due to race on the team’s Pinarello bikes at the Santos Tour Down Under from 16 January 2027.

Aldo Nicotera, Head of Moto & Cycling Business, Pirelli, said, “At the highest level of sport, success depends on a constant search for technological solutions that can deliver ever-greater performance.

TyreSafe has entered an official partnership with BLT Driver Training, the driver training division of the Blue Lamp Trust. The UK charity, which works to raise awareness of tyre safety, said the collaboration reflects a joint commitment to road safety and to helping motorists make better-informed decisions. The tie-up connects BLT Driver Training's work with TyreSafe's broader mission and impact.

The new partner delivers professional driver education, training and assessments intended to raise driving standards and protect passengers, drivers and other road users. Its services span taxi and private hire training, fleet driver development, safeguarding and disability awareness courses and a Mature Drivers Confidence Builder Course. It works with licensing authorities, businesses, fleet operators and individual drivers; as a not-for-profit, it supports the Blue Lamp Trust's charitable work helping older and vulnerable people stay safe.

Collaboration will initially concentrate on three areas: taxi and private hire vehicles (PHVs), mature drivers and fleet safety. Drivers in the taxi and PHV sector cover high mileages on demanding schedules, and the partners will examine ways to embed TyreSafe's taxi-focused campaign materials into training and communications so that pressures, condition and tread depth receive greater attention. For mature motorists and their families, the organisations hope to develop accessible, practical resources that prompt regular tyre checks and informed choices supporting safe driving and independence. Fleet safety will be pursued through TyreSafe's November campaign, with both parties looking at how to share guidance on maintenance, inspection procedures and safety-conscious fleet management.

Bringing together BLT Driver Training's educational expertise and TyreSafe's specialist tyre knowledge, the partnership aims to put practical road safety advice within reach of more people and build safer habits across a range of road users. The two organisations believe the collaboration will help drivers and operators treat vehicle safety as a routine priority while supporting the Blue Lamp Trust's wider charitable mission.

Stuart Lovatt, Chairman, TyreSafe, said, “We warmly welcome BLT Driver Training as a TyreSafe partner. Improving road safety requires a joined-up approach, combining driver skills and awareness with the condition and maintenance of the vehicles they use every day. By working with an organisation that shares our commitment to practical education and safer journeys, we have a real opportunity to reach more drivers, support fleet operators and help people understand the simple checks that can make a difference. We’re particularly excited about exploring resources for mature drivers and their families, as well as working together to promote tyre safety among taxi and private hire drivers and across the wider fleet sector.”

Emma Burt, CEO, Blue Lamp Trust, said, “We’re delighted to be working with TyreSafe to help improve road safety and driving standards. At BLT Driver Training, we believe that effective education gives drivers the knowledge, skills and confidence to make safer decisions, and vehicle maintenance is an essential part of that picture. This partnership offers exciting opportunities to bring practical tyre safety advice into our training and communications, from supporting taxi and private hire drivers to helping mature motorists and their families have constructive conversations about vehicle safety and maintenance. We look forward to working with TyreSafe to develop useful resources and initiatives that help protect drivers, passengers and the wider community.”
