Abstract

The DOE technique is very familiar to an experimental study of any product in manufacturing industry. The most important things of producing the product are by investigating the best solution of the problems occurred and using DOE technique. The problems occurred can be analyzed and an improvement action can be done immediately. There are a lot of advantages of using DOE technique and for example the number of experiments need to be carried out can be define and stated clearly according to the methods that involved in this technique such as Full Factorial, Fractional Factorial, Taguchi Method and etc. Thus, the cost and time can be reduce in product manufacture and also can integrate the product into a high level usage after a few researches had been made. In this project, the scope mostly is to design the experimental study of keris mould using different parameters in the designs made with two different types of level for each parameter. The simulation using MoldflowXpress Analysis software had been done and the result gained then had been analyzed using Minitab software. The result recorded is about injection time of plastic keris mould for each design made. From the analysis process that had been done, the parameter of cold slug seems to be the most effected parameter to the injection time as from the Interaction Plot, only interaction between cold slug and gate recorded for both material used and for Main Effects Plot, the slope of the graph of cold slug is the highest recorded and it means that, the cold slug is the most effected parameter to the responds tested. While for Pareto Chart of the Effects, even though all the parameters do not give any significant effect, the cold slug still is the nearest value to be a significant effect of the injection time.
