Extrusion International 2-2025

25 Extrusion International 2/2025 AI Boom Drives Demand for High-Quality Data Cables – Best Measuring Technology for this New Trend With the huge investments in AI data centers such as Stargate in the USA and Deepseek in China and elsewhere, the demand for high- quality data cables is rapidly grow- ing. The quality requirements for these cables set new standards for the extrusion process. In the past, it was suf cient to con - trol the diameter to the nominal val- ue. Nowadays, however, brief varia- tions in a wide range of parameters of this cable type cause re ections during data transmission. This sig- ni cantly reduces the usable length of a wire pair. Anyone who has to meet the requirements for this cable type on a permanent basis cannot do it without continuously monitor- ing the performance of the extrusion process. Data cables are generally used for data transmission in the range of up to several gigabytes/s. Twist- ed wires with low-loss foamed insulation with minimized reflec- tions can be used for this high data rate up to a length of 100 meters and more. The real challenges with this cable type lie in the short-term, periodic variations and not only in the diam- eter and the scatter of these and other measured values. It is the single value accuracy that matters, not the average of many measured values: SIKORA devices such as LASER, CENTER- VIEW or CAPACITANCE measure diameter and eccentricity values with the highest single value pre- cision, so that decisive deviations and scatter of the nominal values can be precisely recorded.

This means that maximum throughputs of 6000 kg/h are now possible. With the proportioning valve, the precise and reliable addition and mixing of regrind and virgin material is easy to achieve. The proportion and number of mate- rial layers per conveying cycle can be easily adjusted. A large trans- parent access flap enables easy cleaning. The METROMIX Ø76 is now avail- able. motan Group www.motan-group.com METROMIX 76 (motan Group)
