Abstract: A die forging approach of so called IN-OUT way is presented, which, firstly, let metal fulled up die cavity, and then it forced surplus metal to flow out. In this manner, it can control flash forming so as to realize precision forging without or with little flash. The paper explained procedure for executing IN-OUT way, using reverse simulation technique based on UBET. The successful application in production also is introduced.

Key words: Die forging, Numerical simulation, Preform design
