In the traditional quality optimization process of stamping parts, the optimization is mainly through mold adjustment so that the time and quality costs are both higher. With the early vendor involvement (EVI) of professional quality management, the computer aided engineering (CAE) analysis technology is gradually applied in the simulation of stamping automobile parts. In the paper, it is introduced the self-owned material card of Baotou Steel is successfully developed by correctly selecting such characteristic parameters as typical representative performances and yield criterion through taking the DX53D+Z product as an example as well as the research on reliability of material card is completed by the analysis on forming property of products in the Autoform software. It is verified that the self-owned material card of Baotou Steel is with higher reliability and the database of simulation material could provide data support for EVI service.
