ZUMBACH ELECTRONIC proudly showcased its latest innovations in extrusion measurement technology at K 2025, the world’s leading trade fair for plastics and rubber which took place from 8th -15th October 2025 in Düsseldorf, Germany. Our presence at this year’s event reaffirmed our commitment to delivering cutting-edge solutions for the plastics and rubber industries.
At the heart of our exhibit was the UMAC® CI, a high-tech measured value processor designed for real-time wall thickness and eccentricity measurement in extrusion lines. This compact system integrates a powerful processor with a dedicated ultrasonic sensor, offering:
- High-speed precision measuring (up to 1000Hz per channel), ensuring stable accuracy even at high line speeds
- Advanced measuring algorithms for fast setup and seamless integration
- Universal connectivity supporting Profinet IO, Ethernet/IP, Ethernet TCP/IP, OPC UA, RS interfaces, and a USB/Ethernet service port for diagnostics, firmware and data transfer
- Flexible integration interfaces seamlessly with ODAC® laser sensors, KW lump and neck-down detectors and USYS® IPCe processors
- Embedded web server for intuitive visualisation and remote access through any standard internet browser, with no additional software required
- Reliable data acquisition for wall thickness, eccentricity, and other critical parameters
- Wide measuring range from 0.05mm ultra-thin wall thickness, adaptable from micro-tubes to heavy-wall pipes
The UMAC® CI is the result of decades of ultrasonic measurement experience, engineered to meet the evolving demands of modern extrusion environments.
Also debuting at K 2025 were our newly developed UMAC® ultrasonic transducer A-Holders, tailored for tubes and small pipes. These holders are designed to:
- Enable fast and accurate centering close to the extruder
- Support diameters from 0.2 mm to 28 mm (0.008 in. to 1.1 in.), and wall thickness from 0.05 mm to 12 mm (0.002 in. to 0.5 in.)
- 4 or 8 measurement points with optional horizontal/vertical configuration for flat or non-round products, such as busbar
- Dedicated USB service port enabling quick calibration, data logging, and synchronisation wit the UMAC® CI processor
- K & V versions configurable for open-trough or vacuum-tank setups, with height and side adjustment
- Durable, low-maintenance construction, stainless steel and POM body with integrated water rinsing to keep transducers bubble-free
- Plug-&-Play modularity, compatible with R, RZ and Z holders, extending the measurable range up to 400 mm diameter, plus customized solutions up to 1 m diameter
The new A Holders offer fast set-up, stable operation and minimal maintenance, helping manufacturers cut start-up waste and maintain tight tolerances.
In addition to our new developments, ZUMBACH presented its comprehensive portfolio of measurement systems, including: UMAC®; RAYEX® S; SIMAC®; ODAC® and the PROFILEMASTER® PMM with practical demonstrations outlining each product and solution’s features and benefits, as well as precision, efficiency and quality assurance across a wide range of extrusion processes.
