An automotive steel part is required to evaluate its performance and feasibility in the early stage of vehicle development. It is manufactured using prototype die. The hydroforming prototype die for a hydroformed part is expensive as its massive production die. The high cost of the hydro forming prototype die makes engineer to choose a conventional stamping method before hydroforming technology without any evaluations of hydroformed parts. To reduce the cost of hydroforming prototype die plastics are considered. In this paper mono cast nylon for die material is used to evaluate the feasibility of hydro formed parts. The manufacturing time and cost of prototype die can be saved with the die material, mono cast nylon. And the geometry accuracy of the part formed through the mono cast nylon die can be fulfilled with the tolerance ± 1㎜.
