Abstract: This is focused on the analysis of plastic flow in two plate injection mould. Motor rare housing component is designed with multi cavity as the plastic part in the two plate injection mould which is used in domestic motor. Mould flow analysis software is used to perform the analysis of filling, wrap and best gate location. This will discuss the flow of molten plastic inside the injection mould. The analysis begins with the origin of the flow channels such as Barrel, nozzle, sprue, runners, and gates until the cavity is completely filled. In this analysis, plastic flow behavior is studied together with parameters settings in plastic injection mould, Based on the analysis improvement has been made to the part design and feed systems in the mould. This includes the location of the gate at the part design, size of sprue, runners and gates. From the analysis also, CAE helps to determine the part defects that might occurred during plastic injection molding process such as Short shot, unequal filling, over filling, welding lines and others. From that, the optimum parameters setting are selected in order to get a quality plastic. So this will explain the plastic flow analysis clearly.
