Shrinkage Elimination in Casting of GG30 Grade Cast Iron Impellor by using Pro-cast Software& Finite Elemental Analysis by Meshcast Software

There are 100+ submersible pump manufacturers in Rajkot Engineering Cluster. So, there are 100 plus foundry engaged in casting of cast iron impellor for submersible pump. They face shrinkage defect after casting and about 10 % rejection is because of shrinkage.[1] So in order to reduce this defect casting simulation software is very helpful. By using Pro-Cast simulation software mould of impellor is imported in Pro-Cast software and by applying sand mould condition, pouring temperature, pouring time etc. are put into the software, and finally result shows the areas of impellor where shrinkage chances are more.

Strength Prediction for Pearlitic Lamellar Graphite Iron: Model Validation

The present work provides validation of the ultimate tensile strength computational models, based on full-scale lamellar graphite iron casting process simulation, against previously obtained experimental data. Microstructure models have been combined with modified Griffith and Hall–Petch equations, and incorporated into casting simulation software, to enable the strength prediction for four pearlitic lamellar cast iron alloys with various carbon contents. The results show that the developed models can be successfully applied within the strength prediction methodology along with the simulation tools, for a wide range of carbon contents and for different solidification rates typical for both thin- and thick-walled complex-shaped iron castings.

Foundry Technique Designing of the Nodular Cast Iron Casting

The traditional method has been used to the foundry technique for the melt block mobile plate. The pouring position,the parting face and some of the casting parameters were determined, such as the allowance for finish, stripping taper, the rate of shrinkage and soon on. The commercial casting simulation software was introduced into the casting process, the filling and solidification process were calculated by it. The results shown that there are some shrinkage exists in the original technique and the filling process were inordinate. The gating system was optimized and according to the simulation results, the shrinkages in the original technique were eliminated and the filling process is smoothly which could help the designer to make a correct determination.

Casting Process Solutions Optimization of LFC Forklift Box

There are many advantages in producing forklift box through the LFC. However, we found shrinkage porosity defects in the interior of castings through simulating the original process by ProCAST casting simulation software. Therefore, we analyzed the defects and improved the technology program. firstly, increased riser in position of shrinkage, Secondly, changed the filling’s way, lastly, selected the best temperature and vacuum by the orthogonal experiment and determined the best technology solution. we found the shrinkage porosity defects have been removed by the improved process. We found the production consistent with the simulation results through verification. Therefore we verify the accuracy of the ProCAST.

The Numerical Simulation and Optimization in Squeeze Casting of the Air Conditioning Compressor Front Cover

Using the ProCast casting simulation software to make squeeze casting process simulation and analysis of the solidification process of the air conditioning compressor front cover and predict the location of gas volumes and shrinkage defects in the filling process. When adjusted the process parameters, volumes gas defects were eliminated, but there was still shrinkage occurs in the center. When imposed a secondary pressure on the central part, shrinkage was eliminated.

Numerical Simulation of the Car Oil Pump Support Die Casting

In this paper, the die-casting processing of aluminum alloy was simulated by casting simulation software. The mould filling and solidification process of aluminum alloy die-casting in different cast temperature and shot velocity were investigated. Aiming at achieving the best casting process, this research gave emphasis on analysis the influence of cast temperature and shot velocity to the process of mould filling, temperature field of casting part during filling and solidification, shrinkage and porosity. To improve the process, increase ingate area, carry on the simulation, and analyze the optimal casting parameters.
