The use of stress pins as an innovative pre-stressing element was discussed. The results of a design methodology investigation through combined finite element analysis and design of experiment studies for large and non-axisymmetric precision forming tooling were presented. Smart pre-stressing elements were implemented to overcome very fundamental and practical problem of prolonging the die life, preventing die failures and improving dimensional part tolerances by applying local and controlled pre-stressing effects.
