Troester will display its Rotomex technology ZX Series for straining of rubber compounds. The ZX series, which belongs to the group of gear extruders, can produce an output of up to 590-5,500 lbs/h with corresponding rubber density and viscosity. The newly developed ZX 150, ZX 170 and ZX 220 are designed to meet the increasing demand for more output and reach up to 5,500 lbs/h depending on construction size. The compact construction of the ZX series, with proven feed gear shaft technology and simple handling, enable it to be used in the mixing room and the extrusion line. The drive shafts, housing and head are designed to be tempered separately, taking into account rubber compound properties of tires and technical rubber goods. With a processing pressure of up to 35 MPa and continuous monitoring of all relevant process parameters, the new ZX 150, ZX 170 and ZX 220 are able to meet strict requirements.
Rubber processing machinery manufacturer Uth has invested a seven-digit euro sum in the construction of an assembly hall at its base in Fulda in the center of Germany. “Many new developments placed increased demands on our operational resources. For example, our newly developed two-roll plasticizer technology, weighing 40 metric tons, for the preparation of rubber compounds, brought us to our capacity limits,” explains MD Peter J Uth. The investment has expanded the production area by around 1,100m2, to a total of around 10,000m2. Building work began in March and took around five months. The facility has been designed to enable flexible machine manufacturing. High product quality, ergonomics, sustainability and energy efficiency have also been considered in the building’s design. The hall is equipped with underfloor heating, the latest LED lighting technology and daylight-emitting light domes.
Green Tires have proven particularly resource-efficient for cars, where Evonik‘s Silica/Silane technology can achieve fuel savings of up to eight percent. By developing Ultrasil 7800 GR, a silica with a customized surface area that meets the extreme demands of SUV and all-season tires, Evonik has now taken the next step in the innovation. “The challenge for SUV tires is to give the tires sufficient stiffness in spite of their size,” explains Dr. Hark-Oluf Asbahr, Marketing of Rubber Silica. “With Ultrasil 7800 GR, we managed to find the right mix to combine joy of driving, road safety, and resource efficiency in a single product.”
The new filler achieves a perfect balance of maximum grip and minimal rolling resistance in large-surface tires as well as tires with high mileage requirements, such as all-season tires. This is due to the specific surface area of the additiv, which was increased compared to Ultrasil 7000 with extensive development efforts. Using the new silica additiv reinforces the tread compound and gives tires sufficient stiffness. “The direct feedback between the tire and the steering system results in significantly greater safety – including in the case of short and wet braking paths,” explains Asbahr. Improved abrasion resistance also contributes to an extended service life, which has a positive effect on the lifecycle assessment. In this manner, a high level of traffic safety can be combined with lower fuel consumption and reduced CO2 emissions, even in sporty tires. In spite of the high specific surface area, the product is relatively easy to process and permits an efficient, quick production process in tire manufacturing. “The demand for SUVs is consistently on the rise worldwide,” says Dr. Bernhard Schäfer, Head of Rubber Silica. “That‘s why it was particularly important to respond to market impulses and to develop a new product that is meeting tomorrow’s requirements now.

Rea Jet At the Tire Technology Expo Rea Jet will be presenting innovative inkjet and laser marking systems which make every part unique. Direct coding makes products clearly identifiable, supports counterfeit protection and is the basis for the optimization of production and logistics. For years, the rubber processing industry has been relying on the market leading Rea Jet large character technology when it comes to contact-free inkjet marking of raw rubber felts, treads and finished tires. The new generation of the printing system DOD 2.0 has been significantly improved by new production processes and advanced material which leads to extended operating cycles. With protection class IP65 the robust printing system is even more resistant. It can be operated via tablet, smartphone and touch display or by using the push-turn jog-dial knob even with gloves. If required, it can be integrated into the company‘s existing IT infrastructure for synchronized processes according to IoT. the company also presents the coding and marking system RPS that marks rubber reliably at all stages of the tire production with environmentally friendly water based inks at low costs. Moreover, the system allows for easy and fast data exchange. Markings are applied directly and contact-free onto the surface. Coded products can be identified and the degree of automation and production capability can be increased via track and trace and global traceability is assured. If required, markings can either disappear during the vulcanization process or captively bond with the rubber.
When information has to be applied in the smallest of spaces, the thermal inkjet printers of the HR series with HP cartridge technology set standards. At the REA booth, rubber pieces will be marked with logos, machine-readable barcodes and 2D codes. Also demonstrated are maintenance-free and consumable-free laser systems. Laser marking is first choice when permanent, captive marking onto finished tires is required. To ensure highest quality of their machine-readable barcodes and 2D codes, machine builders rely on the REA VERIFIER code verification systems which complement the portfolio of coding and marking solutions for the rubber processing industry.
MonTech will showcase its rubber test instruments, including its new fully automated online robotic testing cell. Housing multiple stations including binning, sample preparation, MDR, RPA and density, the testing cell provides relevant batch information in real time by bringing a quality lab to the mixing line. Applying complete automation and robotics enables faster batch release, higher sampling rates, less scrap, less rework, decreased variability in testing, and ultimately a lower cost per test. The idea for the project came from high-capacity mixers, such as tire plants, which require technology that can reduce overhead laboratory costs, while increasing testing rate, reliability, repeatability, and accuracy of the data they were collecting. Combining robotics and testing instruments was the only option. The company’s online testing cells allow, for the first time, closed loop control between mixing, testing and downstream processes. Through direct integration into mixer controls, the testing cells can provide quick feedback for precisely controlled processes at a higher quality output.
Visitors to the Metravib stand will find details of its new dynamic mechanical analyzer (DMA). The latest DMA+ concept incorporates unique capabilities for applying dynamic test methods to a rubber compound specimen under various shapes, dimensions and testing modes (compression, shear and tension). The DMA+ series enables extremely high-accuracy measurement of a material’s viscoelastic properties and their dependence on strain, frequency, temperature (Young, shear modulus, tan delta, glass transition, Payne and Mullins effects, high-frequency testing, fatigue, creep and stress relaxation). Metravib will also introduce Xpander, its new automated specimen handling system designed for the DMA+ series for compression, tension and shear tests. Featuring high autonomy, Xpander is designed to operate round the clock, 365 days a year, making it possible to continuously test more than 400 specimens.
Numerous studies have shown that some laboratory test results do not sufficiently correlate with the behavior of technical rubber parts in terms of lifetime and wear while they are in service. PRL, the elastomer expert group of Coesfeld, develops measuring methods and suitable instruments with whose help the properties of rubber material can be predicted. The target is the early simulation of real loading conditions of rubber material in laboratory scale. The most important first step to reach the goal is to analyze and describe as exactly as possible how a rubber article is tortured under real service conditions. On the basis of the analysis PRL’s research team specifies the technical capabilities as well as evaluation algorithms of suitable test appliances to do a high-grade, correlating prediction. The latest development is new test equipment to characterize the heat build-up process in situ. It uses unique multiaxial measuring capabilities such as dynamic alteration torque and multi-planar bending versus programmable load cycles. Therefore the appliance controls the user-defined loading conditions in a wide range of combinations. This instrument enables observation of the heat build-up process and measurement of the mechanical properties that are changing at the same time.
One of the many technology debuts at the show will be GLM’s cutting-edge new measurement tool, which combines two systems, enabling simultaneous measurements of the outer tire contour and the inside of the tire. A prototype system will be shown for the first time and set up as a demonstration to show how the measurement method works on part of a tire (though the actual system can be used to measure on a whole tire). The Tube Inspector measures the tire’s inner geometry with a small sensor and integrated camera to create a sectional profile of the inner wall. The contactless measurements result in 2D sectional images and 3D measurements upon rotation of the tire. Within 10 seconds a full 3D measurement is made and is ready for evaluation. The Tube Inspector is a great tool for fast analysis of inner geometries. The outside of the tire is captured with four sheet-of-light sensors. Two sensors record the tread area and the other two read the sidewalls. The sheet of light outer contour measurement captures the tire profile, deformations, symmetry and reads the sidewalls. The whole geometry of the outer tire is recorded within 10 seconds. Both measurement units together create a tire system with 0.1mm resolution, which provides the required data for detailed tire analysis.
Kuraray will present its liquid rubber portfolio, consisting of liquid isoprene rubber (LIR) and liquid butadiene rubber (LBR). Conference speaker and technical manager Marcel Gründken will have more information about how using liquid rubber can lead to safer and faster tires. Liquid rubber acts as a co-vulcanizable plasticizer and provides a rubber modification that exceeds the pure plasticizing effect. His presentation introduces the different liquid diene rubbers. Depending on the backbone and microstructure, liquid rubber can modify tire performances such as abrasion resistance, rolling resistance and wet grip, as well as snow and ice grip. In particular the latter can be greatly improved by LBR. This will be discussed by way of DMA characteristics and ice grip test results.
Cold Jet will be showcasing its patented MicroParticle technology that helps tire manufacturers to more efficiently control and improve the critical mold cleaning process. Taking into consideration mold complexity, compound, venting system and the cleaning process either online or offline, tire manufactures can use this new technology to significantly increase their mold cleaning process outcome. Cold Jet says its enhanced dry ice MicroParticle technology ensures a better, faster, safer, quieter, non-abrasive and more efficient clean with the lowest media (ice and air) consumption. By resizing any common dry ice, and in combination with the Cold Jet Sure Flow technology, considerably more dry ice MicroParticles can strike the surface in any given time, able to reach areas where 3mm pellets and conventional methods cannot clean. Cold Jet dry ice cleaning allows for in-place cleaning, without major disassembly or cool down. The non-abrasive media, in the form of recycled CO2, will not damage the mold, therefore enabling rubber molders to extend their running times and enhance their productivity.
Laser system specialist 4JET Technologies will launch its next-generation STMCS laser mold cleaning system during Tire Technology Expo. The redesigned system is now available for tire mold sizes ranging from typical passenger car sizes, to truck and bus tires. New features include an automatic mold-loading feature and a two-table design for maximized throughput. The system will be exhibited live at the show. Other exhibits include 4JET’s new JETLASER handheld laser cleaning system and updates on 4JET’s SCANNECT QR code marking technology for tire traceability.

Industry 4.0-capable components like the Festo VTEM Motion Terminal offer many advantages for the loading and unloading process for tire presses. These are shorter cycle times, lower energy costs, reduced unplanned downtimes and fewer spare parts to keep in stock. This new automation platform opens up a new world of flexibility, adaptability and simplicity – including future opportunities for programming new apps for customized solutions.
Lanxess Deutschland, BU Rhen Chemie will present Rhenocure DR, a secondary accelerator for rubber. Diphenyl guanidine (DPG) is the most used secondary accelerator in silica filled passenger car tread compounds Beside its function as secondary accelerator DPG acts in this application also as a processing aid. A problem accompanied with DPG is that it releases carcinogenic aniline during the vulcanization process. Several solutions are available to replace DPG like Vulcuren or Rhenocure SDT/S. For carbon black filled compounds the new secondary accelerator Rhenocure DR, a polyethylene imine (PEI), has been developed. As sulfur and aromatic free chemical this product does not influence the crosslinking density.

Beumer Group will showcase its automated tire handling system, which delivers higher productivity and efficiency than conventional systems. By automating the handling of green tires, the company’s Tire Tray System virtually eliminates the risk of the tires being damaged or deformed during the build and finishing processes. The Tire Tray System offers tire manufacturers higher capacity throughput using less equipment and space, at a lower cost. In the automated system, green tires are placed into a ‘tray’ that transports them through the complete build-to-curing process. No additional handling is necessary. The Tire Tray System combines transportation, sortation and storage of green tires in a single system. Each tire is loaded into an individual-controlled tray as it leaves the tire building machine for storage or transportation direct to the curing press while remaining in the same tray. This avoids any need to grip, lift or reposition the tire, ensuring that it is not damaged in any way.

Krauss Maffei Berstorff presents a new rubber compounding line – CompoundRework system 1000 (CRS 1000). This innovative solution is designed for processing scrap material generated during extrusion processes in the rubber processing industry. The CRS 1000 stands out for maximum ease of operation and is suitable for a wide range of different materials. „Most extrusion processes inevitably involve the production of a certain amount of recyclable scrap, i.e. residual material that remains in the extruder or in the extrusion head in the event of compound or extrusion tool changes. In order to maximize added value, tire producers strive to recycle this scrap material by returning it to the production process,“ says Joachim Brodmann, Key Account Manager at KraussMaffei Berstorff. „The CRS 1000 processes large-volume rubber residues removed from the flow channels as well as start-up scrap converting the material into sheets or strips with a thickness of 8 mm. This means that 100% of the residual material can be returned to the production process.
The CRS 1000 is equipped with two (optionally) heated rolls and a hydraulically adjusted roll gap. It can be fed with residual material of various sizes up to a width of one meter. The generously dimensioned feeding unit with automatic intake gap is equipped with all required safety features to minimize the risk of personal injury. Easy access substantially facilitates maintenance and cleaning operations. The simplified control of the complete line enables one-man operation, which gives easy machine handling and enhanced operational safety. In addition, the sturdy design and energy-efficient drive technology ensure cost-effective and high-performance system operation on a sustained basis.
As the CRS 1000 comes with the complete electrical equipment and control system, it is ready for start-up immediately upon installation. With a total weight of about eight metric tons, a volume of just under 4 m3 and 5 m2 footprint, the complete unit can be easily transported to any place of installation using industrial trucks.
On 20 February 2018 at 5.30 p.m., interested visitors to the fair will be given the opportunity to experience a live demonstration of the CompoundRework system 1000 on the KraussMaffei Berstorff premises. They will be able to witness first-hand how easy it is to recycle production scrap and convert it into strips and sheets.
