The global IDDRG community has, like all other communities, been affected by the COVID19 crisis. The annual IDDRG conference 2020 (IDDRG 2020) was planned to be held in Busan, South Korea, on 7-11 June 2020. However, due to the Corona situation and thanks to the enormous efforts by the Korean colleagues, the successful IDDRG 2020 was held virtually on 26-30 October 2020. The executive committee of IDDRG has therefore discussed the annual conference schedule for the coming years. This schedule has now been modified after discussions with and based on the suggestions from the organizers of the IDDRG conferences 2021-2023. After many considerations and conversations with the members of the IDDRG community in different countries, a new schedule was outlined. We would like to inform that- IDDRG 2021 will be held virtually on 21 June – 2 July 2021. Professor Mathias Liewald, Universität Stuttgart, will organize this conference. Please visit www.iddrg2021.uni-stuttgart.de for more information. We also refer to the coming separate communication from Professor Liewald and Universität Stuttgart, Germany.
- IDDRG 2022 will be held in-person in June 2022 in Lorient, France. Professor Pierre-Yves Manach, Université Bretagne Sud, will organize this conference.
We look forward to the support of the global IDDRG community for the coming virtual IDDRG 2021 organized by Stuttgart, Germany, and the in-person IDDRG 2022 in Lorient, France. The Executive Committee of the International Deep Drawing Research Group (IDDRG) January 8, 2021

This handbook presents a compilation of the technologies and advancements that have been developed over the past 30 years in press forming technology. The study includes the identification of a technology for the future development of press forming technology. It also examines the development of press forming technology as a joint effort in the two technological fields of processing technology and materials manufacturing technology, and as a joint effort that spans two industries, namely the automotive industry, and the steel industry.
