www.kistler.com 19 Analyzing: Injection Molding Process Analysis and Optimization DataFlow provides a range of tools across the entire process chain: During mold sampling and optimization, DataFlow provides process data in a variety of different graphics in order to speed up the mold sampling process and to utilize the full optimization potential. During process optimization, DataFlow can be used to determine process tolerance limits and to evaluate processing properties based on the measured data. In this way, the system reduces mold sampling times and ensures a fast optimization of the process. The determined tolerance limits can be used for monitoring part properties and quality assurance during the production process and dispense with the need for manual examination. During mold set-up, cavity pressure reference curves can be stored. Optimized molds can be operated fast and efficiently on different machines and the optimum operating point can be determined quickly. During production DataFlow calculates from the measured process data maximum values, freely definable integrals, the filling index and the injection work. Moreover, the system allows the definition of tolerance ranges. Transgression of these tolerance ranges by the values recorded from the current process will either trigger an optical notification or lead to an activation of the reject gates or robots. DataFlow provides automatic quality assurance for molds with large numbers of cavities and integrates it into the process. Trend graphics can predict errors in the active production process to eliminate them. Networking statistics allow statistical production analysis (cp, cpk values, production distribution) for the purpose of documentation. Automatic reports provide a documentation of quality for customers. Statistics data generated by DataFlow can be used to detect and eliminate weak points in the production process and help to determine the reject quota while the production monitoring function can then be used to directly identify the cause of excessive rejects.
