| Abstract | This paper presents a three-dimensional (3D) solution algorithm for solving the sequential co-injection moulding process. The ow of skin and core materials inside a rectangular cavity is investigated both numerically and experimentally. A 3D nite element ow analysis code is used to solve the governing equations of the non-isothermal sequential co-injection moulding. The predicted ow front behaviour is compared to the experimental observations for various skin=core volume ratio, injection speed, injection temperature, and core injection delay. Simulation results are in good agreement with experimental data and indicate correctly the trends in solution change when processing parameters are changing. Solutions are also shown for the lling of a spiralow mould. The numerical approach is shown to predict the core expansion phase during which the ow front of core and skin materials advance together without breakthrough. Breakthrough phenomena is also predicted and the numerical solution is in good agreement with the experiment. |
