Purpose: This paper presents an overview of the hot close-die-forging (HCDF) and aims at drawing up some new ideas and conclusions about future development of the HCDF. Design/methodology/approach: Exploring the literature survey and the author's experience, the state-of-art of the HCDF is defined. The reason to do this are signs of instability in development of HCDF - a production method, well known due to its advantages, concerning both dimension accuracy and favorable mechanical properties in effect of micro structure changes. Findings: This study shows advantages, possibilities and feature development of the HCDF. Challenges and possible response to them have been discussed. Research limitations/implications: Analyzing the experience gained until now, the possible new research fields have been shown: forging of new materials, new understand ness of near-net forging, combining operations, physical and numerical simulations. Practical implications: HCDF is a production method, well known due to its advantages, concerning both dimension accuracy and favorable mechanical properties in effect of microstructure changes.
