In an effort to improve service to our customers and expand our technical capabilities, Pace decided in 1996 to develop predictive analysis capabilities. Predictive analysis is computer simulation of real world applications.
The various types of predictive analysis that we perform are listed below:
- Flow analysis: Flow analysis is concerned with the filling of the die cavity with molten metal. The results of this analysis will indicate areas in a casting where there are potential gas porosity issues or filling issues that cause surface defects.
- Thermal analysis: Thermal analysis is concerned with the solidification of the molten metal in a die cavity after it has been filled. The results of this analysis will show areas in a casting where there is a potential for shrinkage porosity.
- Thermal Stress Analysis: Thermal stress analysis is concerned with how a casting changes shape after it is removed from the die and cools to ambient temperature. This is important if flatness is a potential issue.
- Finite Element Analysis: Finite element analysis (FEA) is used to predict the strength of a casting. Using FEA allows us to optimize the strength of a casting while minimizing the amount of material added.
- Computational Fluid Dynamics: Computational fluid dynamics (CFD) predicts the heat transfer through a given casting geometry. We can optimize the size and placement of cooling fins on castings using CFD techniques.
