In the paper presented we did an experimental method for optimizing the die casting process. The method applied was developed by Taguchi and experimented in one Romanian Automotive Company in order to improve the design of the engine in automotive. I decided to propose the above method in the discovery aspect of a very serious problem facing the production department in one company that produce automotive aluminum parts using die cast process. Because we want to discover a solution to remove the porosity which is the biggest problem in die cast design and process. We have plans to startimplementing the experiment for all the parts produced. The experiment conducted for the implementation of the method has been desired to be applied to eliminate this porosity problem and was based on six trials in which it found the ideal combination of factors and the level at which they must be in order to reduce percentage of parts which are outside the tolerance of porosity characteristics.
