Abstract
The invention relates to a molding process of subscriber identity module (SIM) cards, in particular to an SIM card injection compression molding process. An SIM card mold is in a hot runner mode, and a mold core is needed to be designed in a counter-deformation structure. The temperature of a material barrel arranged on an injection molding device is controlled to be 230-260 DEG C, the temperature of the SIM card mold is controlled to be 15-35 DEG C, and the drying temperature of injection molding materials is controlled to be 75-85 DEG C. The injection molding pressure is controlled to be lower than 2000 kg/cm<2>, the backpressure is controlled to be 30-60 kg/cm<2>, and three-stage pressure maintaining is adopted. The injection speed is controlled to be 90-200 mm/s, the injection position is divided into three sections, the cooling time is within 2.5s, and the molding cycle is controlled to be within 8s. By adopting the SIM card injection compression molding process, acrylonitrile butadiene styrene (ABS) materials can be stably used for massively producing the SIM cards, and harm to human bodies and pollution to the environment can be reduced.
