[0002] Seat hook assemblies are important components of car seats. They are connected to pins through bushing holes to enable the installation of seat hook assemblies. Therefore, bushing pressing is one of the key processes in the production and processing of seat hook assemblies. In the standard process, the bushing must first be pressed out to a 45-degree angle, and then pressed out to a 90-degree angle to meet the assembly requirements. The pressing accuracy directly affects the smoothness and comfort of the seat opening and closing.
