ENHANCEMENT OF WELD LINE IN ABS AUTOMOTIVE COMPONENTS VIA GAS - ASSISTED MOLD TEMPERATURE CONTROL
This research paper focuses on reducing the weldline defectives in an ABS molded part through an innovative technique involving the introduction of gas into the cavity. The aims of the experiment to assess the impact on weld line visibility in comparison to the conventional method of using water for cooling within the cavity. The aim is to reduce rejection of molded ABS parts, which are produced using LG MP 220 Grade materials, intended for automotive applications with subsequent plating. To conduct this study, specimen samples were produced using an injection molding machine. Three different sizes of gas vents were employed, allowing gas to flow through the tool's cavity. The research is to then collect data on the resulting weld lines which are measured for comparison and employed to comprehensively analyse and interpret the effects of gas cooling across varying vent sizes in contrast to traditional water cooling. This statistical analysis facilitates the determination of the optimal vent size based on experimental findings and to compare the same with the traditional water-cooled products.
