Hot stamping: manufacturing functional optimized components
Production Engineering, 2012Due to rising requirements regarding passenger safety and weight reduction hot stamped components get more and more important regarding security relevant parts because of their high strength. Currently, the new challenge is manufacturing components with locally adjusted mechanical properties in order to simultaneously guarantee structural integrity and

Development of concurrent stamping-piercing trimless hot stamping process
Journal of Mechanical Science and Technology, 2017After a material undergoes hot stamping, post-processes are required to ensure that the final product has the expected quality. Typical post-processes are mechanical or laser trimming and piercing. These post-processes are expensive and time consuming because when the material undergoing hot stamping cools, its strength becomes very high.

Development of a hot stamping clinching tool
Journal of Manufacturing Processes, 2018Abstract A hot stamping clinching tool that integrates a forming system, a heating system and a cooling system is developed. A traditional heating furnace is replaced by resistance heating technology. DEFORM-3D is used to simulate the heating process, cooling efficiency and formability in the design stage.

Trends and challenges in hot stamping technology
AIP Conference Proceedings, 2017The main motivation for the lightweight concepts in automotive sector is nation and international legislations to decrease the CO2 emission. The use of lightweight technologies or lightweight materials or the combination of both is indispensable. In this paper we present hot stamping as a solution of using lightweight technologies which could be used ...

Robustness of the Tailored Hot Stamping Process
Advanced Materials Research, 2014The final mechanical properties of hot stamped components are affected by many process and material parameters due to the multidisciplinary nature of this thermal-mechanical-metallurgical process. The phase transformation, which depends on the temperature field and history, determines the final microstructure and consequently the final mechanical ...

The International Journal of Advanced Manufacturing Technology, 2013
Although high strengths up to 1,500 MPa can be obtained by means of hot stamping, the strength and uniformity of components cannot be guaranteed during mass production if the cooling channel is not properly designed. In this paper, we propose a method for designing the cooling channel by means of the energy balance principle and arrangement methods ...

Analysis of Hot Stamping for Automotive Structure
Applied Mechanics and Materials, 2013In order to optimize the hot stamping process of an A-pillar and speed up getting the product to the market, we separately simulate forming and heat transfer to get a better tooling design. In the analysis of forming, the thinning rate is under 30%, we judge that there is no crack issue.

History and Future Outlook of Hot Stamping
2018Hot stamping can be traced back to traditional Japanese sword making techniques of thirteenth–fourteenth centuries [1]. The earliest patent about “Presharten” (Press hardening) was granted in 1914 in Switzerland. The technique described in this patent has been used in agricultural products since 1930s [2]. Hot stamping, as we know it today differs from
