Kansai Tsushin Densen Co., Ltd. relies on inline measuring technology from SIKORA
Kansai Tsushin Densen faced the common industry hurdle of detecting material abnormalities in real time. Relying on post-production sampling and manual inspections meant that fluctuations in diameter or eccentricity often went unnoticed until a significant amount of scrap had already been produced. This reactive approach led to high start-up losses, as production had to be halted and restarted repeatedly whenever a structural issue was eventually identified in the take-up section.
Beyond physical dimensions, the company needed to ensure the electrical integrity of high-frequency cables, such as 12G-compatible products. Fine periodic fluctuations caused by equipment vibrations or conductor inconsistencies could compromise impedance stability. Without live data, it was nearly impossible to pinpoint these micro-defects during the extrusion process, threatening the high-performance standards required for modern communication and broadcasting networks.

Solutions from SIKORA
High-speed cable production requires a synergy of hardware and sensors to capture data invisible to the human eye. Inline integration shifts manufacturing from reactive troubleshooting to a proactive, automated environment. This ensures every millimeter is scrutinised for physical and electrical integrity, maintaining high-performance standards from start to finish.
The Solution
The implementation of SIKORA’s continuous inline measuring technology transformed the production floor into a data-driven environment. By integrating high-speed sensors directly into the line, the facility gained the ability to monitor insulation thickness and capacitance simultaneously. This proactive monitoring allowed the technical team to identify eccentricity trends and outer diameter shifts the moment they occurred, enabling immediate adjustments that prevented defects before they could propagate.
To maximize the utility of the hardware, the system was paired with a sophisticated processor for real-time visualization and data logging. This integration eliminated the need for traditional structural inspections at the start of a run. Instead of waiting for a physical sample to be verified, operators could rely on accurate trend data to confirm product quality instantly. This streamlined start-up process drastically reduced the consumption of expensive resin and conductor materials.

The Result
The transition to SIKORA’s inline technology allowed Kansai Tsushin Densen to virtually eliminate the “guesswork” period during production start-ups. By relying on immediate digital feedback rather than waiting for physical samples to be measured manually, the company achieved a significant reduction in start-up losses, saving substantial amounts of high-cost resin and copper. This efficiency boost not only lowered operational overhead but also increased the overall capacity of the production line.
Beyond material savings, the implementation secured a higher standard of electrical reliability for their 12G-compatible products. The ability to perform real-time SRL and VSWR analysis meant that fine periodic fluctuations were caught and corrected instantly, resulting in a cable with perfectly uniform impedance. For the end customer, this translates to a guaranteed, high-performance product supported by transparent, data-backed quality assurance reports.
