| Summary: | The effect of injection process parameters on plastic part quality such as dimensional shrinkage (DS) and warpage deflection (WD) is studied using visualisation method of transparent glass mould. Injection moulding machine parameters such as injection time, holding time, injection pressure, packing pressure, mould temperature, and melt temperature are selected. The injection machine parameters are set-up to find the effectiveness of the responses that are DS and WD. Gate location at centre, left and right side of product will be taken consideration of polymer flow in machine direction (MD) and transverse direction (TD). To ensure flow pattern can be easily seen, master batch will be mixed with plastic pellet. Further, image from visualization results will be compared with simulation modelling, to get the reasons, how polymer flow in mould cavity affected the DS and WD. The optimization process in simulation will be analyzed using Moldflow software. Selection the best injection parameters will be selected from modelling simulation. Then, simulation analysis of product quality on DS and WD will be performed. Finally, validation will be performed by measured the moulded plastic part using optical profile projector. Our expectation is that DS and WD of plastic part at MD and TD can be reduced through analysis of polymer flow image with the help of experimental and simulation analysis. |
