| Résumé : |
In the last decade, injection molders have increasingly come to focus on mold temperature control. Temperature-control units with a speed-regulated pump form an ideal complement to closed-loop controlled water manifolds. Since they are integrated into the machine control system, synergies arise that allow easy determination of the flow rates that are actually required, automatic setting of the pump speed, and consequently a significant reduction in the energy consumption. |

- An overall view
- FIGURES : Simulated heat distribution in a mold with two cavities and three temperature control channels. The arrow directions indicate the flow direction of the heat-exchange medium ; the arrow lengths represent the flow rate - 2. With the automatic rotary speed control the total energy consumption of the injection molding system can be reduced by 20 % - 3. Required pump output for temperature control of two circuits with different pressure losses. For better comparison, the flow rates were chosen such that a maximum temperature difference of 3K is established - 4. To make the system, comprising temperature-control unit and manifold, clearer, a new user interface was developed. All the temperature-control components are grouped together on one page : the mold with its cooling circuits, which is shown symbolically is located in the center. - 5. The e-temp temperature control units from HB-therm are integrated into the CC300 control system of the engel injection molding machine via OPC UA. OPC UA is becoming increasingly more popular as the communication standard for the smart factory of the future |
