Application of CAE for Precision Material Forming of Electric Parts

정밀 전기, 전자 부품 성형을 위한 해석 틀의 활용

The key factor of quality in precision metal forming is to meet the requirements of parts size and shape. Particular problem of unflatness occurs frequently. This study focuses on figuring out the cause of unflatness. To predict the amount of unflatness after ejection from tool, equivalent temperature method is used. This method, temperature equivalent to the final stress value is calculated, and it is applied as the boundary condition of the linear static analysis. The final of formed part is used as the geometry model of the static analysis.
