Extrusion International 2-2026

26 Extrusion International 2/2026 MEASUREMENT TECHNOLOGY QC Off-Line Measuring Devices for Precision Quality Control Zumbach Electronic – the world-leading manufacturer of inline measuring solutions for over 60 years – has recently unveiled its latest innovation in precision measurement technology: the QC non-contact, off-line measuring stations, designed to deliver fast, accurate, and repeatable measurements for wire, cable, and tube samples. These systems set a new benchmark for quality control in manufacturing environments, ensuring compliance with exacting speci cations and enabling production optimization. QC 2: Advanced Measurement for Wire, Cable, and Tube Samples The QC 2 system combines cutting-edge components to provide unparalleled accuracy and ease of use, and consists of a high-precision diameter measuring head, a motorized rotating sample holder with automatic sam- ple ejection for piece measurement, and a USYS-Touch processor with specialized software for data evaluation. This system is ideal for quality control laboratories or factory oors, offering operators a simple, repeatable solution for measuring outside diameter and ovality. Unlike traditional micrometers or mechanical indica - tors- which can suffer from calibration errors or opera- tor variability – the QC 2 guarantees consistent results regardless of user input. Key advantages of the QC 2: • Accurate and user-friendly measurement method • Quick feedback for production optimization • Automatic rotation and measurement start with a single key press • Specially designed rotating holder for precise sam- ple positioning • Comprehensive statistics (min, max, average, stan- dard deviation) at the touch of a button • Data upload capability for further processing QC 4: Precision for Hose and Tube Samples For hose and tube applications, Zumbach offers the QC 4 system, which measures outside diameter and calculates inside diameter and wall thickness. Like the QC 2, it deliv - ers fast, accurate results and can be deployed in both QC labs and on the plant oor, providing operators with a simple and repeatable solution for measuring parts or cut samples of ex- truded products. Key advantages of the QC 4: • Simple placement on a reference pin • Multiple measurements around the sample circumference • Two statistical modes: ▶ One measurement across several samples ▶ Several measurements on one sample QC 2 – Wiremeasurement QC 2 – Piece Measurement QC 4 – Piece Measurement
