Die Casting is a precise method of casting which puts the liquid into a deform metal mold mode with high pressure. This has the advantage of mass production with low cost. By now there are only a few products manufactured in this way of casting. Besides, the process was generally complicated, and some of these products were subject to surface defects.
Recently, the progress and development of Taguchi method has become a tendency due to its recyclable features. This method has been playing important role in industrial community for manufacturers to promote their products with high quality.
The purpose of this experimental research is to explore the most suitable parameter combination in Aluminum felly’s high-pressure process and to reach the high quality level with the lowest development cost. This research mainly provides a three-step processes of optimum improving strategy to optimize the setting of the parameter for Aluminum felly’s high-pressure process and to reduce the failure rate. The first step is to get the parameter level through the control flew. The second step uses the Taguchi method to get the experiment plan with a proper parameter setting using the L27 orthogonal table to control the quality elements SN ratio as the standard for evaluate the quality feature and also the results of the reaction analyzed picture will be used in robust manufacture process in order to improve the product variant the final step using reaction curve align parameter up to optimum set. Through this research of improvement the defect of real process is reduced from 1.03% to 0.33. The improvement range is 68%.
