Abstract：

The closed precision forging process of flange less than one inch (flange diameter less than Φ130 mm) and the key issues in its automatic production and application were mainly introduced. First, according to the characteristics of forgings, the machining allowance of forgings was designed to be 0.5-1.0 mm (not excluding the allowance added by the middle hole and draft), and the difference between one forging process and two forging processes was compared to determine the forming process. Then, according to the characteristics of automated production, some issues that needed attention in process and mold design were summarized, and the suggestions were given. Finally, the problems that easily occurred in automated production to affect normal production were summarized, and the suggestions were put forward. Thus, the qualified flange precision forgings were produced by the designed closed precision forging process of flange, the mold life met the requirements of automated mass production, and the stable production cycle was about 300 to 400 pieces per hour according to the difference in product weight.
