- Abstract:
- In the gas—assisted injection molding，foaming structure in the gas channel region is a key factoraffecting the mechanical and optical performance of the GAIM part．An experiment was carried out to study theeffects of the processing conditions on foam formation in the gas—assisted injection molding，using quantitativeanalysis method．The relationship between the processing parameters and foam formation on the gas channelwall was discussed and the reasons leading to foam was analyzed．The results reveal that foam can be avoidedby lowering the melt temperature，reducing the gas injection pressure and the holding pressure as well as theholding time．
