The parts made of composite materials can meet the special vehicle manufacturing process requirements of various host factories. Before installation and baking on the paint line, the expansion block product does not change, ensuring that there is an appropriate gap between the parts and the sheet metal, allowing the side cavity of the vehicle to flow and exhaust during several processes such as welding, acid washing, electrophoresis, and wax washing. After baking on the paint line, the cavity is foamed and sealed. The company has been developing EMA/EVA car body cavity sound insulation expansion block composite materials since 2005, which have been successfully applied to car body expansion parts of OEMs such as SAIC Volkswagen, FAW Volkswagen, and Shanghai General Motors for more than ten years, with stable and reliable quality.
