| Résumé : |
Injection is the process step in injection molding that is most quality critical. The injection speed profile and its reproducibility have a direct influence on the internal and external properties of a part. The adjustment of the injection step is therefore of particular importance. Engel injection-molding machines with electrical injection units now feature optimized setpoint computation of this profile, with clear visualization, which increases the process transparency and ease of operation. |
| Note de contenu : |
- Smooth or dynamic ?
- Expected speed profile before the first cycle
- Input merges with the output
- Fig. : With immediate effect, Engel is equipping all injection-molding machines with electrical injection units with an optimized setpiont computation for the injection speed profile
- Fig. 1 : The precalculated speed profile (broken line) shows the expected speed profile based on the setpoint values. By changing the profile dynamics, the movement can be made more gentle or more dynamic. The effect is visible directly during the movement of the slider
- Fig. 2 : The graphic display in the CC300 shows all th eimportant information at a glance. The injection profile is displayed from right to left, corresponding to the direction of movement of the screw. The green lines represent the speed curves and the red line, the pressure curve
- Fig. 3 : The red area stands for the pressure control. It illustrates the holding pressure phase and possible intervention by the pressure limit controller |
