Simulating the process in a virtual environment allows for minimizing the investment, meaning less time is required and the results are better. We can say that simulation is absolutely necessary in a wide range of manufacturing sectors – in aeronautics and automotives, for example – where components need to be absolutely free of microstructural defects and where scrap can’t be reutilized. The software used in this process is from the French ESI Group, and it is called ProCAST. This is a complete and cutting-edge tool that has been on the market for more than 20 years, and it has been widely used in different industrial fields. ProCAST is able to foresee what areas of an object might have defects and the extent of them. Simulating the microfusion process is a useful tool that doesn’t completely eliminate the need for trial and error, but it limits it to the virtual environment, reducing the time and costs of industrializing a product».
