The Present Situation and Developing Trends of Hot Closed-Die Forging

Abstract

Due to its advantages including high quality of the forging parts and low production costs,hot closed-die forging (HCDF) play an essential role in the machine building industry. However, in recent decades, the pace of its development is gradually slowing down. In the hope of drawing up some new ideas about future development of the HCDF, this paper presents a brief overview of it. This study roughly prospects several potential research issues of the HCDF. Some new research fields such as precision forging, combined forging and numerical simulation have been shown. Challenges and possible response to them have been discussed.
