| 제목 | Rule of thumb and its Criterion to predict gas flow directions in gas assisted injection molding |
| 초록 | The control of gas direction is thus one of the most critical aspects in the application of the technology. The rule of thumb on the direction of gas flow for GAIM has been investigated [Lim and Soh,1999; Soh, 2000; Soh and Lim, 2002; Lim and Lee, 2003; Lim, 2004a, 2004b; Lim and Hong, 2004] and simulation packages were used to verify the gas direction predicted by the rule of thumb. In this paper various rule of thumbs and flow models were introduced and integrated. The gas path was predicted to change by flipping the lower side pipes, pipe 2, which was consistent to the result of simulation. Neither the flow rate ratio nor the ratio of resistances to flow rates can be a criterion in the prediction of preferred direction of gas. The resistance to initial resin velocities should be a criterion in the prediction of preferred direction. For various geometries including pipes and fan-shape between two flat plates, the rule of thumbs suggested were quite capable of predicting the direction of gas flow in gas assisted injection molding. |
