FEM Simulations for the Optimization of the Inlet Gate System in Rapid Investment Casting Process for the Realization of Heat Exchangers

Abstract Over the last decades, additive manufacturing (AM) has become principal production technology for prototypes and components with high added value. In of metallic parts, AM allows producing complex geometry a single process. Also, admits joining elements that could not be realized traditional methods. addition, using other types processes like reticular structures in heat exchangers. A solid mold investment casting uses printed patterns overcomes typical limitations such as expensive machinery challenging process parameter settings. Indeed, rapid provides foundry epoxy pattern reproducing component to exploit lost wax this paper, aluminium radiators flat pipes seamlessly connected cellular structure were conceived produced. This paper aims at defining investigating parameters achieve defect-free exchanger. For purpose, different device CAD models designed, considering four pipes’ thickness length. Finite element method numerical simulations performed optimize design Three gate configurations investigated each The investigations led definition castability range depending on parameters. optimal configuration was applied realization
