The purpose of the study was to obtain castings with increased mechanical properties by low-pressure casting using excess pressure on the crystallized casting. The simulation of the process of filling and crystallization of prototypes using the SPH method was carried out. The studies were carried out on a modernized low-pressure injection molding machine model U8261. Prototypes were obtained from AK7ch alloy, special attention is paid to interfacial interaction and intensification of the heat transfer process due to the application of excess pressure. Based on the data obtained, it was found that during crystallization under excessive pressure there is a supercooling effect that reduces the casting solidification time. The use of the SPH method for modeling foundry processes has shown a high level of reliability and requires further development.

Using the method of numerical simulation and the AnyCasting software, the simulation for SDAS of Al-Mg alloy wheels for low pressure casting is studied. The simulation model is established and the effects of preheating temperature, melt pouring temperature and cooling water pipes on SDAS in the low pressure casting process was founded. The results show that, SDAS presents linear variation with the increase of preheating temperature and pouring temperature; opened cooling pipes make SDAS smaller. The practice of simulating casting is verified by experiments, and test results and simulation results were consistent.

Low Pressure Casting

Effects of electromagnetic filling parameters on Density of Al-Si alloy in low pressure casting were investigated. The key influential factors on Density of Al-Si Alloy were determined by orthogonal testing. The results show that the influential orders of electric current, magnetic inductivity and cyclic time on the density of the ZL114 alloy are as follows: electric current, then magnetic inductivity, and then cyclic time. Electric current and electromagnetic field can effectively improve the density of the ZL114 alloy in low pressure casting.
