Design and optimization of cooling channels in hot stamping dies applying additive manufacturing design concept

Abstract

The stamping process is a process that represents a key manufacturing process in the automotive industry. With the implementation of the stamping process, mechanical elements obtain mechanical resistance, in addition to a very low ratio in quantity/cost. Within the design premises that govern the automotive industry, it is worth highlighting the requirement for mechanical resistance, passenger safety, and the lightness of materials. All of this contributes to the current use of alloyed materials with high mechanical resistance. These materials in addition to keeping the mechanical requirements of the different components subjected to load, must satisfy the geometric requirements established by the designers. In the last few years, the use of the Ultra High Strength steels has grown in the automotive industry. This type of alloyed steel contributes to car safety and clean mobility. Given the mechanical nature of these ultra-high-strength alloys, they require the use of hot stamping. This makes the deformability of the different steels easier and allows that, using a conventional stamping method, would not be able to deform according to the geometric requirements of the different mechanical components.
