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 Bridgestone Potenza Sport EVO, incorporating ENLITEN Technology, secured the top position in the 2026 summer tyre test conducted by sport auto magazine. Evaluated in size 205/45R17 on a Mazda MX-5, it emerged as the clear leader among seven competing tyres. It was the sole tyre to earn the prestigious ‘outstanding’ rating, achieving 9.2 points for its overall performance.

The testers commended the Potenza Sport EVO for its remarkably balanced capabilities. They characterised it as a tyre combining high safety with an exhilarating driving experience, declaring it their definitive top choice. The evaluation noted the tyre's abundant grip and precise handling during challenging manoeuvres. The experts described it as a highly responsive tyre with substantial grip in reserve on both wet and dry roads while praising its fine controllability through load variations.

Its proficiency in wet conditions was a significant highlight, demonstrated by short braking distances, tenacious cornering grip and robust safety margins against aquaplaning. Developed from the multi-award-winning Potenza Sport, this new model elevates sports performance, wet control, durability and efficiency. Available from January 2026, the tyre ensures precise control at high velocities, preserving vehicle composure. It attains a top-tier EU label A-grade for wet grip, and compared to its predecessor, it reduces wet braking distances by five percent and dry braking by two percent.

These advancements are complemented by superior longevity, with a 15 percent mileage increase, translating to roughly 6,000 extra kilometres. Furthermore, it enhances fuel economy and boosts electric vehicle range through a rolling resistance reduction of up to six percent.

DUNLOP has announced the launch of its BLUE RESPONSE TG, a new premium summer tyre developed for passenger cars and SUVs. Suitable for internal combustion, hybrid and electric vehicles, the tyre will be available in 99 sizes spanning 15 to 21 inches, series 40-65 with H, V and W speed ratings. Production takes place at a state-of-the-art facility in Türkiye, with European market availability scheduled for March 2026.

This launch represents a significant shift for the brand in Europe. BLUE RESPONSE TG is the first DUNLOP product developed under Sumitomo Rubber Industries (SRI) since it acquired the historic brand’s passenger car tyre rights in 2025. The tyre was engineered collaboratively by DUNLOP’s teams in Germany and Japan, drawing upon SRI’s established manufacturing and development capabilities.

The ‘TG’ designation stands for ‘Touring,’ underscoring the tyre’s ability to deliver long-distance comfort and efficiency while maintaining strong performance. A suite of new technologies ensures stability and control on both wet and dry roads. Impressive braking performance is a key feature, enhancing overall safety and driver confidence.

Central to the tyre’s capabilities is an intelligent three-zone rib design that efficiently channels water away from the contact patch. This promotes stability at higher speeds and unlocks reliable wet-weather grip during directional changes. A refined shoulder design features lateral grooves set at optimised angles. This enhances tread rigidity, reduces block deformation under load and ensures consistent force transfer when cornering and braking.

Durability is addressed through a new tread compound utilising longer, more resilient polymer chains. These resist abrasion and slow wear to extend mileage without compromising performance. To complete the package, a noise-reducing tread design links lateral grooves into continuous channels. This smooths airflow and dampens vibration, resulting in a noticeably quieter cabin environment and the composed, refined ride expected from the DUNLOP brand.

The first Sprint weekend of the 2026 Formula 1 season began in China with an intense schedule, starting with Sprint Qualifying on Friday. George Russell claimed pole position, finishing over two-tenths of a second ahead of his teammate Kimi Antonelli, with Lando Norris securing third. Russell received the Pirelli Sprint Qualifying Award from Dario Marrafuschi, Pirelli Motorsport Director. The prize includes a helmet decorated in the colours of the Chinese flag and a replica Pirelli P Zero Soft tyre, both personalised with the driver’s name and number.

Pirelli’s compound regulations shaped the qualifying format. In SQ1 and SQ2, drivers were required to use a set of medium tyres, with most completing two fast laps per segment. For the final SQ3 shootout, the top 10 switched to the soft compound. Russell’s pole time of 1:31.520 came on the red-walled P Zero Soft, less than seven-tenths slower than the 2025 sprint pole time of 1:30.849, set by Lewis Hamilton.

The F1 Academy also opened its season in Shanghai, with Alisha Palmowski setting the fastest time in Friday’s qualifying. She outpaced Alba Larsen and Emma Felbermayr ahead of the series’ two races scheduled for Saturday and Sunday.

Marrafuschi said, “During Sprint race weekends, it’s always challenging for teams to fully assess tyre behaviour as they only have one hour of free practice. During this session, the teams used one set of medium tyres and one set of soft tyres, without carrying out any significant long runs. The hards were saved for the following days, and some teams may consider using them in their strategies for Sunday's race as early as tomorrow.

“The Sprint race, which is most likely to be run on Medium tyres, will certainly provide a clearer picture. The performance difference between the two compounds used on Friday is around six tenths. Interestingly, in the first two qualifying segments, the C3 was once again able to deliver maximum performance on the second push lap after completing a cooldown lap.

“Temperatures are cooler than last year; the track is still dirty and has less grip than we will see on Sunday as the track evolves. As happened last year and as expected, some graining appeared on the front-left tyre, which is the most stressed by Shanghai’s corners, and to a lesser extent on the front-right, although the impact on overall wear remains limited. On this circuit, teams tend to prioritise protecting the front axle, shifting the balance towards the rear as much as possible.”

Nexen Tire has received a ‘Good’ overall rating for its N'Fera Sport model in the latest summer tyre test conducted by Auto Bild in March 2026. The assessment highlights the tyre's strong performance within the competitive Ultra-High-Performance segment.

Tested on a BMW 5 Series (G60) with size 245/45 R 19 tyres, the N'Fera Sport distinguished itself through exceptional braking capabilities, achieving the third-shortest stopping distance among 50 competitors in the qualification phase and demonstrating excellent safety margins on both wet and dry surfaces. The tyre further impressed with its precise steering response and reliable grip, even under challenging conditions. Its overall performance secured it the third-place position in the qualification round. Notably, the N'Fera Sport also excelled in acoustic comfort, ranking second out of 20 tyres for low noise generation.

These results underscore the model's blend of control, responsiveness and safety, making it suitable for both everyday driving and more dynamic scenarios. Nexen Tire views this recognition as a validation of its ongoing commitment to innovation, quality and the production of high-performance products designed to enhance the driving experience.
