A virtual foundry can be an opportunity and a tool for solving economically costly problems, which include complex training of employees or prediction of costs for foundry castings. Virtual foundry is the application of the principles of digital twins to the foundry industry. Despite the fact that some companies have already started to create digital twins, this is a complete novelty in the foundry industry. Virtualization has many undeniable advantages, including not only the visualization of the environment, as has been the case in the past, but also the interactivity of the environment and the possibility of calculations from various areas. The aim of this article is to present some of the modern trends of digital twins in connection with Industry 4.0 and also to present two possibilities how to create a virtual foundry. There are several ways to create a virtual foundry. The first option is to use the NavVis M6 scanning device, which is able to photograph the environment not only as a photograph, but also scan the environment as a cluster of points and then convert it to CAD as a 3D model or use the Indoor viewer software application for virtual browsing. The second option is to use a combination of Blender and Unity programs (which are suitable for creating interactive 3D environments) and the C # programming language for modeling metallurgical production units.
