| Abstract Scope |
A key issue in producing high-quality aluminium automotive components by the High-Pressure Die Casting process (HPDC) is minimizing the defects. For the HPDC technology, the wall thickness of components needs to be monitored because it dramatically affects the grain size and pore's appearance. In this work, local squeeze technology is used in aluminium high-pressure die casting. The aim is to optimize quality in thick sections of complex geometries, where designers cannot modify component's features and the casting process cannot solve shrinkage porosities with the state of the art process control like intensification pressure or cooling management. The present paper relates to a study of the squeeze pin effect on HPDC aluminium parts, where material homogeneity for leak prevention is a must. Both product and process development for reliable industrialization of the local squeeze technology will be covered, from casting virtual simulation to the metallurgical analysis of the affected area. |
