[0002] With the progress of the connector industry and market changes, improvements have been made in both product performance and size. Products are constantly being upgraded, and the corresponding manufacturing processes must also be upgraded. The product in this example consists of two hardware parts and an injection molded part. If the traditional production method is followed in injection molding production, that is, the puller pulls two strips and feeds them into the injection molding machine for injection molding, this solution is suitable for single strip injection molding, but not for double strip injection molding at the same time. The disadvantages are: ① Two pulling mechanisms are required, and the investment cost will increase; ② When pulling the material, the other side of the terminal cannot be limited, which will cause problems such as pressing hardware and overflowing glue, and increase the defective rate. ③ When the two strips are superimposed together, the precision is not enough, and product quality problems will occur. Therefore, in order to solve the above problems, reduce production costs, and ensure product performance requirements, a manufacturing method and process flow for riveting strips are designed and invented.
