Abstract

The competitiveness of automotive industry is going at its peak. By releasing automotive products faster than others, automotive companies can maintain strong and remain competitive to strive to the top. However, problems faced during the research and development (R&D) phase of new product such as the existence of critical defects will delay the planning time, thus lengthen the product development lead time. Plastic parts of automotive that are manufactured by injection moulding also faced this problem, where defects always happen after they are manufactured. So, actions must be taken to ensure the defects are reduced or prevented at the first place. In Autodesk Moldflow Analysis, the part will be analysed, melt flow will be reviewed and defects that may happen can be predicted. Taguchi approach is used as Design of Experimental (DOE) method to optimize the design of part and feed system to ensure the best design is used. The part chosen is car door trim armrest cup and the defects analysed are short shot, weld lines and air traps. Based on the results, Experiment 5 and 1 show the best feed system design with least defects. This is due to the smaller diameter of sprue, runner and gate, thus conclude that diameter of feed system plays important role in reducing mould defects.
