In the highly regulated field of medical tube manufacturing, precision and quality control are paramount. Consistent wall thickness and accurate diameters help maintain the desired flow rates of fluid or gases through the tubes, where any irregularities can lead to complications like blockages or improper medication dosages, potentially endangering patients’ lives. ZUMBACH Electronics’ advanced measurement and control systems play a crucial role in enhancing the efficiency and reliability of the production of the highest quality medical tubes.
A global leader in non-contact measuring technologies, ZUMBACH Electronic, has over 30 years of experience in the development of ultrasonic measurement systems used in the measuring of wall thickness and concentricity of medical tubes. The UMAC®, utilizes ultrasonic measuring techniques that outperform alternative technologies and is the only solution able to measure and recognize materials as individual layers in co-extrusion applications.
The UMAC® provides accurate in-line measurements for ultra-thin tube walls down to 0.08mm and can handle product diameters ranging from 0.2mm to 350 mm. Integrated into the UMAC® is the System on a Chip (SoC) unit called UMAC® CI. This expands capabilities with recipe-based operation (without requirement of manual setting manipulations based on the echo signal display), provides a 1kHz sample rate and integrated webserver. It also offers numerous industrial communication protocols for expansive integration with PCs and PLCs utilizing Profinet IO and Ethernet TCP/IP, amongst others. Our A-Series transducer holders allow the use of 4 or 8 measuring transducers. The top transducer, when in place, is removable, allowing for easier machine setup, while integrated guide solutions ensure product centralization. An optional height adjustment solution allows for under-bath or over-bath adjustment in vacuum or open-bath extrusion situations. An integrated water flow distribution is standard and ensures air and gas bubbles are removed from the measuring area, for greater accuracy and measuring reliability.
The ZUMBACH USYS processor complements this advanced ultrasonic measuring solution by running the highly specialized WALLMASTER software. This software can manage recipes for different products, save measured data and offers statistical calculations and reporting functionalities. Its real-time capabilities include greater control of the extrusion process, as well as automatic compensation of the wall-thickness based on auxiliary diameter measurements. It also enables further expansion of the overall measuring solution through the integration of other measuring ZUMBACH solutions, such as ODAC laser measuring heads and KW fault detectors.
Key Features of the UMAC® Range:
- Ultrasonic Multi-layer Measurement: Utilizes ultrasonic technology to accurately measure wall thickness and concentricity of up to 5 layers simultaneously. Ideal for complex multi-layer products.
- In-line & Real-time Monitoring: When integrated with the USYS WALLMASTER software, the system allows for continuous in-line measurements and real-time control of the extrusion process, ensuring consistent quality.
- Economically & Technically Advantageous: Offers reduced setup times, raw material savings, scrap reduction and fully automated control, whilst providing complete process transparency.
