The calibre of low pressure casting (LPC) process in meeting the demands for improved quality and aesthetics for thin walled components has been widely accepted in casting industries. In spite of numerous advantages, the process is still being used very less to its potential. The basic reason has been the difficulty in determining various processing parameters associated which can be circumvented effectively by numerical simulation. In the present work, the commercial CFD code FLOW 3DTM, has been used to simulate the mould filling and solidification during the LPC process.

The low-pressure casting method has been used to the foundry process of bolster. According to the structural characteristics of the cast and the design process of low-pressure casting, the process programs had been accomplished. Through comparing the advantages and disadvantages of several group programs by computer simulation, after determining the initial process program, we optimized the casting process according observing the processes of cast filling and solidification by the computer simulation process of running castings. The risers and chills are very important. The contraction area of cast appears on the large flat, and the risers had been set on the large flat. This can not only play the role of feeding but also have the function of scavenging action.

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.

Filling And Solidification

Filling and solidification for aluminum alloy packing block in die casting were simulated by numerical simulation. Distribution and change of temperature field as well as velocity field were visualized. The desirable processing parameters can be obtained with pouring temperature of 620°C and mould temperature of 180°C as well as shot velocity of 4m/s. The qualified products were obtained on the basis of the optimized die-casting parameters.
