Die Design and Manufacturing

In typical (cold) stamping operations, the dies are only used to plastically deform the metal material. In hot stamping, on the other hand, the dies are used to form the material and extract the heat energy from the blank. All this has to be done as quickly as possible to improve the part quality (to ensure martensite formation is completed) and part productivity. This chapter discusses the requirements from a hot stamping die, how they are designed, and how they are manufactured.
