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.

PT Tiga Berlian Mandiri (Tiberman), an Indonesian importer and distributor of tyres and wheels, used Tiberman Expo 2026 to showcase its expanding business portfolio, strengthen industry partnerships and launch a new renewable energy business.

Held at the company's Super Area in Gresik, East Java, the exhibition brought together representatives from more than 70 companies, government officials and international tyre suppliers. The event featured hundreds of tyre and wheel products and was hosted at one of Tiberman's 15 Super Areas across Indonesia.

Built around the company's philosophy, "We Provide Solutions", the exhibition focused on integrated business solutions for industries including transportation, logistics, mining, plantations, manufacturing and construction, rather than solely on product displays.

The event also served as a platform for collaboration between industry, government institutions and international partners. Visitors explored tyre and wheel solutions for commercial vehicles, trucks, buses, heavy equipment and specialised industrial applications, while Tiberman sought to strengthen customer relationships and support improvements in operational efficiency and reliability.

Alongside the exhibition, Tiberman Group inaugurated the second warehouse of PT Fie Min Logistics, its bonded logistics and warehousing subsidiary. Representatives from the East Java Regional Office of Indonesia's Directorate General of Customs and Excise officiated at the opening.

According to the company, the new facility will increase storage capacity, improve distribution across Indonesia and enhance customer service.

Tiberman also announced the launch of PT Ethlon Energy Indonesia, marking its entry into the renewable energy sector.

The new company will provide consulting, system integration and installation services for solar photovoltaic power systems, targeting mining companies, plantations, industrial operations and large corporate customers. Tiberman said the expansion reflects increasing demand for energy solutions that are more efficient, reliable and environmentally responsible.

The company said the move broadens its position from a product-focused business to an integrated solutions provider spanning tyres, wheels, logistics and renewable energy.

During the exhibition, Tiberman also received two recognitions from the Indonesian World Records Museum (MURI). The awards recognised what the company described as Indonesia's first tyre featuring a batik motif on its sidewall and the first tyre incorporating inspirational quotations into its tread design.

PT Tiga Berlian Mandiri said the exhibition reinforces its long-term strategy of expanding its distribution network, strengthening logistics capabilities and developing new business segments while supporting customers across multiple industries through its nationwide network of 15 Super Areas.

Birla Tyres has officially joined the Automotive Tyre Manufacturers’ Association (ATMA), becoming the newest member of the leading industry body. The company, with its registered office in Kolkata, operates a large-scale manufacturing facility in Balasore, Odisha, which spans 195 acres and is dedicated to producing a diverse range of speciality tyres.

Based in New Delhi, ATMA represents major tyre manufacturers that account for more than 80 percent of domestic production. The association serves as a vital link between the government and the industry while also engaging with media, opinion leaders and international trade bodies to advocate for the sector’s perspectives.

ATMA actively participates in policy formulation and regularly consults with government departments on economic challenges affecting the industry. Its existing membership includes prominent firms such as MRF Tyres, JK Tyre & Industries, CEAT Ltd and Bridgestone India, the local subsidiary of the Japanese tyre giant.

Bridgestone has reported a significant shift in UK consumer sentiment regarding electric vehicles, with new data indicating a sharp rise in drivers who reject the technology. The tyre manufacturer's survey reveals that 26 percent of motorists now declare they will never purchase an EV, up from 17 percent in 2025, while only 16 percent plan to acquire one within the coming year.

Persistent operational anxieties continue to overshadow the market. Battery durability and replacement costs trouble 55 percent of respondents, half worry about charging expenses and 44 percent express unease over range limitations and high sticker prices.

Infrastructure inadequacies further compound hesitancy, as 43 percent feel public charging stations remain insufficient and 41 percent are deterred by prolonged recharging times. Despite these barriers, 53 percent anticipate purchasing an EV within five years, while seven percent remain undecided.

Bridgestone is reinforcing its commitment through 'EV Ready' tyres like the Turanza 6, engineered for efficiency, safety and wear life across electric and combustion vehicles. These innovations align with the company's E8 Commitment and Ecology pillar, advancing sustainable tyre technologies and mobility solutions.

Drew Chapman, North Region Consumer Sales Director at Bridgestone, said, "Electric vehicles are becoming an increasingly familiar sight on our roads, but our research shows that many drivers still have genuine questions and concerns about making the switch. While some of the barriers are gradually reducing, issues such as battery life, charging costs and infrastructure remain front of mind for many motorists. The industry has made significant progress, but it's clear there is still work to do in building confidence among consumers.

"Whether drivers are behind the wheel of an EV, hybrid or conventional vehicle, they want products they can trust. Our focus is on helping motorists get the very best from their vehicles today while supporting the mobility solutions of tomorrow."
