The thickness of product is less than 1mm and product compares flowing length to thickness (flow length ratio L/t) to be living above 150 of injection molding filling. This situation is called thin wall injection molding. This study uses MoldFlow software for material (PP), different processing parameters (injection time, melt temperature, mold temperature, injection pressure), various fiber (glass, long glass), different fiber ratio (40%, 50%) and different thickness (1mm, 0.9mm) to simulate the result on notebook computer. The result shows that the mold temperature is the important factor on processing. The mold temperature, melt temperature and injection pressure of thin wall injection molding are higher than convectional injection molding.
