| Abstract: | Gas assisted injection molding(GAIM) was used for the manufacture of plastic armrests. The influences of important parameters on GAIM were discussed respectively. CAE analysis was also carried out by using a set of software called C mold to match actual experiments. It is shown that the position of gas entrance, melt pre injection volume, melt temperature and delay time are sensitive parameters for gas penetration length and surface quality, and gas pressure is not a very influential parameter of this product. Polymer with high melt flow rate is easy to process on GAIM alike on conventional injection molding. It is also shown that CAE is an effective way to optimize the influence factors of processing and trial and error of the tool. |
