Investment casting, also known as lost-wax casting or precision casting, is a manufacturing process that can produce complex metal parts with high precision, excellent surface finish, and minimal machining requirements. This casting method is suitable for a wide range of materials, including ferrous and non-ferrous alloys such as steel,...
After determining the optimal process parameter group, reset the process parameters according to the optimized process for numerical simulation. The optimized results of shrinkage porosity and porosity are compared with the results of traditional schemes, as shown in Figure 1. From the figure, it can be seen that the...
Use orthogonal experiments to investigate the influence of various factors on the maximum shrinkage porosity. Based on 9 sets of experimental results, calculate the mean of the maximum shrinkage porosity and porosity under different levels of each factor, and calculate the range Rx of each factor by subtracting the...
Create a 3D model of the investment casting and gating system based on the designed gating system, and import it into ProCAST software for defect prediction. Mesh the imported model. In order to improve the accuracy of the calculation results, the unit grid density is set to 4, and...
The design of the gating system directly affects the quality of investment castings. The gating system is generally composed of a gate cup, a sprue, a transverse sprue, and an inner sprue. Due to the unique structure of the ball valve, changing the structure and size of the pouring...
Mix gypsum and water in a ratio of 100:45, stir thoroughly until all bubbles in the gypsum slurry are exhausted, and coat the surface of the impeller mold with gypsum slurry, as shown in Figure 1 (a). Pay attention to the fact that the blades should also be filled...
For the convenience of analysis, this article only conducts defect analysis on a single investment casting. The pouring system structure of 304 stainless steel ball valve under traditional technology is a stepped pouring system, and the distribution of shrinkage porosity and shrinkage defects is shown in Figure 1. Through...
