| Résumé : |
Cyclically measured process parameters are used for monitoring and optimizing injection molding processes. In the past, attention was focused on axis movements and the associated necessary forces and times. Now, the software package iQ weight monitor goes a large step further. It generates process parameters that are relevant for component quality: injected volume, melt viscosity variation, and pressure deviations during injection. |
| Note de contenu : |
- Focus on filling procedure
- Classics under scrutiny
- Process parameters with significance
- Reduced outlay, large benefits
- Process monitoring with control possibilities
- FIGURES : 1. In spite of their limited significance, melt cushion and flow number were frequently used in the past for process monitoring - 2. Changes of injection volume, viscosity, and the pressure curve can influence component quality. In the worst case, as shown here, various interference factors occur together. For better understanding, very large deviations from the reference curve have been selected here - 3. the respective actual process parameters are shown clearly on the display of the machine control system. The traffic light colors indicate which values are within or outside the tolerance range
- TABLES : 1. Intentional manipulations of the process and their influence on component weitght and also on the two process parameters melt cushion and flow number. The colors indicate the significance of the process parameters. Green : The process parameters has changed in the expected direction. Red : The process parameter has changed contrary to the expectation - 2. Intentionally introduced process changes and their influences on component weight : The process parameters injection volume and viscosity change in the respective expected directions. The changes of injection volume are greater than for component weight, as the sprue was not taken into account in the latter - 3. The iQ weight monitor provideshighly significant process parameters |
