Abstract

This study was conducted to design and analysis of a plastic product in plastic injection mould using multiple cavity mould as its main project. Foldable Clothes Hanger are designed as the plastic part in the multiple cavity injection mould. SolidWork software is used to design the plastic part and MoldFlow Software is used to perform the analysis of filling and packing. This research discussed the flow of molten plastic inside the injection mould process. The study done by considering the suitable gate to locate for the selected part in designing three-plate injection moulds. Then, the Moldflow Mold Adviser is used to analyze the effect of the material flow to sprue, runner and gate for three-plate moulds. In the final stage, Moldflow Mold Adviser helps in simulation to suggest the best position of gate location, equivalent injection time and melting temperature during plastic injection moulding process, to show the sink mark, weld line, air trap estimated and skin orientation based on gate location, part design and used. The analysis of MoldFlow Mold Adviser also helps to determine the part defect that might occurred during plastic injection moulding process such as short shot, unequal filling, over filling and others. Besides that, it analyzed the warping and cooling quality estimated based on part and cooling channel designed. To sum it all up, design and analysis of multiple cavity mould were able to be done by using this software and the significant of studies were achieved on this paper.
