Some approaches on industrialization of steel thixoforging processes
TypeArticles dans des revues avec comité de lecture
Based on several years of research, this paper presents some approaches on industrializing steel thixoforging processes. From a billet to a complex-shaped final part obtained in one single step, several key elements of the forming process are developed, such as heating system, transfer system, part and die design. A series of key characteristics is listed to obtain a viable application to high frequency industrialization of thixoforged parts. This work demonstrates that it is possible to use a classical forming press, to implement an automatic transfer of the semisolid slug and to thixoforge with a closed-die process. With a technological approach, a scientific topic is developed to identify generic parameters on thixoforged parts and lines.
