| Résumé : |
Based on simulations and prototype production, the influence of an additive manufactured injection molding tool cavity on the manufacturing process was investigated. Due to the improved cooling performance, the cycle time can be reduced by approximately 10 %, whereas at the same time, a high dimensional stability of the polybutylene terephthalate (PBT) component can be achieved. |
| Note de contenu : |
- Metal substitution for the new mobility
- Conformal cooling from additive manufacturing as the method of choice
- Highest dimensional accuracy as a must for metal rep
Lacement
- Increasing cooling performance for higher production efficiency
- Gentle material treatment while faster processing
- Successful realization of the project
- Fig. 1 : Left: conventional cooling, component and conformal cooling channels from additive manufacturing and component.
- Fig. 2 : Top view of the housing. The warpage of the component after simulation with conformal cooling at the interface to the cover is visualized
- Fig. 3 : Comparison of surface temperatures at the end of the cycle for different cooling methods.
- Fig. 4 : Comparison of the surface temperature at the back of the hotspot for conformal and conventional cooling
- Fig. 5 : Picture of the finished component : the housing of an electromechanical actuator made of PBT. It is lighter by 35% compared to aluminum in this design |
