The design methodology and design evaluation of automotive oil pan dies for laminate sheet metal are discussed in this paper, The forming processes and design<br/> characteristics of the dies for laminate sheet matal based on the oil pan are first introduced, Thereafter, the design of the tools is seen with the explanation of auto-design program, which is developed for generating the drawings of die structures associated with 7 forming operation steps.<br/> Next. the design analysis of the tools for pursuing optimal designs. namely. forming analysis and structural analysis, are demonstrated. Sectional forming approach is employed for checking the formability. and elastic 3-dimensional FEM is used for assuring the strength. The design evaluation revealed the uniform stretching over the region and the safe strength of structure.<br/>
