급속냉각시스템에 의한 메탈릭 수지의 사출성형 특성 향상에 관한 연구

다국어 초록 (Multilingual Abstract)

Most of the plastics products are being manufactured by injection molding process, which has a merit for producing complicated shape precisely. Also, the latest trend is that as the demand of plastic products increased, many polymer processes have been developed. One of them is injection molding process for metallic resin.
However, processing difficulty or unexpected defect occurs due to polymeric materials with metallic pigments. Several molding defects are appeared according to the control parameters during injection molding. The main cause is compounds that are produced during injection molding process. Therefore, these compound contents for molding are very important parameter for metallic plastic injection molding.
This study, which was theoretically and experimentally performed for compound contents, was conducted according to molding condition. Various compound contents were also examined for the condition of mold cooling such as rapid cooling system.
Injection speed of 70mm/s showed higher compound contents than 30mm/s and rapid cooling decreased compound contents by 65% of normal cooling.
Compound contents according to change of injection pressure is not much different and rapid cooling decreased compound contents by 22% of normal cooling.
Pigment contents with 1% showed higher compound contents than 0.3% and rapid cooling decreased contents by 49% of normal cooling.
Also ABS XG569C polymer showed less compound contents than HG173 polymer.
