Traditionally, casting and machining are used to manufacture tools although in recent years, additive manufacturing has gained significant interest due to the design freedom offered. However, the high temperatures of the formed materials over numerous cycles and the significant cooling required to ensure desirable component properties necessitate advanced tooling designs. The process offers low-forming loads and high formability as well as parts with high strength and minimal springback. Hot stamping is one of the most established processes for advanced steel and aluminium alloys. Over the past decades, advanced steel and aluminium-forming technologies have seen considerable development, resulting in significant weight reduction of vehicle components. Vehicle weight is closely correlated with fuel consumption and range for internal combustion and electrified vehicles, respectively, and therefore, weight reduction is a primary objective. However, in order to fully confront the sustainability challenge in the automotive industry, lightweight design in additional to alternative propulsion technologies is also required. Vehicle electrification in particular has received increased attention, and major manufacturers have already undertaken significant investments in this area. Sustainability is a key factor in an automotive OEMs’ business strategy.
