Research of Fluidity for new LPIC Technology

Today, the emphasis is on rapid development and research of new technologies in all technical fields. In most cases, research and development involves practical experiments, which can be very costly to carry out. Some experiments may not even work and can waste time and money, which are crucial for fast and high-quality research. In order to avoid these problems before conducting a practical experiment, we can use numerical simulation software, which is very reliable when the correct input parameters are given. Numerical simulation of the process can reveal how the practical experiment may turn out even before its implementation. The paper deals with the use of numerical simulations in investigating the problem of fluidity in a new low pressure investment casting (LPIC) technology, where the output is the agreement between the simulation and the practical experiment. The practical experiment consisted in the design of a fluidity test for stainless steels cast using the low pressure investment casting technology and the simulation carried out in simulation software. The new LPIC technology makes it possible to achieve a wall thickness of between 1 and 0.5 mm for steel castings, which significantly increases the potential of steel castings made by LPIC technology.
