TEX = Technology + EXcellence

The new generation of JSW Crotating Twin-Screw Extruders, the TEXα III Series
For JSW, the Japanese steel giant, it was only a small step to introduce the efficient high-end compounding machine to the market – TEXα III. The company has a long tradition and history in excellence and innovation. High Throughput and trouble-free processing are the hallmarks of this cutting edge technology. It comes as no surprise to learn that the JSW corporate value is ‘monozukuri’ (Japanese for excellence in manufacturing), the prime element in the JSW DNA. The result: outstanding products, innovative solutions, superb service, first and foremost – every time.
Tradition, in-depth application of expertise and a constant eye on customers’ requirements have led JSW to continuous success. Process economy and the environment are also top priorities. Today, the company is involved in highly engineered compounding equipment. Not only the for the standard range of polymers but also for complex engineering plastics for the medical, automotive, electronics and optical industries, among others, are efficiently processed.
Torque is a key factor in the faultless performance of the TEXα III extruder series. Applications include high quality economic compounding, masterbatch production, devolatilization, rubber/elastomer and dewatering. The beneficial results are complex mixing with highest possible throughput compounding and improved conveying capacity.
Compared with the TEXα II series, which are the conventional extruder from JSW, the newly designed gearbox, screw shaft (utilizing improved materials and new design) and barrels result in improved torque of the TEXα III by as much as 36 percent. Complex alloys developed exclusively in JSW’s own steel refining mills have been used to improve strength and durability. The obvious benefits are longer lifetime, higher output capacity, improved production qualities by more aggressive kneading and mixing, or reduced polymer temperature with lower screw speed, combined with increased performance, improved performance reliability and enhanced quality.
“As a major player in the plastics manufacturing industry, JSW is unique; the company benefits from its own ladle refining of special steel grades, based in Muroran/Japan. This is a vital factor in the production process for screws and barrels, where special alloys are a crucial performance enhancing factor”, emphasizes Tadashi Gion, sales executive and liaison officer at JSW’s European headquarters in Dusseldorf, Germany.
The latest generation TEXα series comprises seven models, with barrel diameters ranging from 26.5 to 129.5 mm, and a torque range between 387 and 43,969 Nm per the two shafts. A high precision torque limiter ensures mechanical and safety protection under operation with highest torque load. This is a vital measure to safeguard the equipment and prevents downtime. A water-cooled motor is optional, assisting in noise reduction..
Tadashi Gion concludes: “We support our customers to be market leaders in their field. That requires forward-looking technology, being ahead of the game. We have insight into the most demanding user requirements. Customers aim high and we have the same philosophy! Our Technology Development Center in Japan is one of the world’s leading plastics processing research facilities. Here, more than 10 installed extruders are continuously developing new processes and applications”
The next step in the product development is already well under way. The company has recognised the need for a more sophisticated lab extruder, tailor-made for the growing European market. This extruder, the TEXα will be exhibited in the upcoming IPF, Japan’s largest plastics industry exhibition, held in October of this year.
