Control Systems REAL-TIME MULTIVARIATE FAULT DETECTION SenseLink™ QM data monitoring system provides an entire solution for process monitoring, fault detection, and part quality prediction utilizing multivariate analysis (MVA) technology. Adding MVA to your process will provide the highest level of process monitoring and fault detection attainable. All necessary data acquisition, multivariate processing, electrical and control functions come from a self contained, compact unit. The multivariate libraries and automated modeling functions were developed by Umetrics, the market leader for MVA software. Adding SenseLink QM to your injection molding processes will provide in-process fault detection along with contribution details which provide an understanding of your process not attainable from traditional SCADA and SPC approaches. Only SenseLink QM integrates the entire multivariate process, from collection to modeling to run-time control, into a single, compact package. The SenseLink QM hardware is designed as a highly integrated industrial computing platform, which can be mounted near almost any process. Process data can be acquired from analog, digital, serial, and/or networked sources, and can be downloaded in chart, text, or CSV formats. All configuration and model creation are accomplished via a web browser user interface, requiring no software installation. Out-ofspec parts are diverted automatically, based upon alarm thresholds setup with the MVA results, eliminating the downstream costs associated with the acceptance of poor quality molded parts. Features & Benefits • • • • • Identify the quality of parts in-process Excellent multivariate prediction capabilities with existing machine sensors; does not require mold cavity sensors Compact; easy to mount and integrate Easy web browser configuration and data analysis; no additional software required Automatic part containment • Production reporting • More efficient preventative maintenance scheduling • Real-time process control with VP switchover capabilities • Setup using automated modeling process, does not require MVA training • Data acquisition up to 100 Hz (Future 1000 Hz)

The SenseLink QM is a data acquisition system with a multivariate data analysis engine that was developed for injection molding. The system can, however, be used with other plastics manufacturing processes or secondary operations to provide significant ROI benefits through improved process understanding, shortened process debug times, reduced scrap, and improved quality control. Applications • Injection Molding • Blow Molding – Extrusion and Injection • Insert Molding • Compounding • Welding • Thermoset Molding • Multi-shot Molding • Gas Assist Injection Molding • Painting Operations •...

• Summarizes multiple signals into easily understand- able plots • Models can adapt to acceptable process changes resulting from material viscosity, environment, time, etc. • Ability to analyze multiple variables simultaneously • Correlation structure between all process variables is determined • Filters out process noise • Reduced false alarms over typical univariate methods • Process variables contributing to poor quality are easily identified Correlation Structure Example – MVA charts can detect changes in the relationships between variables System Components Each SenseLink QM system is...
