Abstract: Disclosed is a method for designing molding conditions of a pressing die. In one embodiment, the method for designing mold conditions of a pressing die comprises the steps of: preparing a mold in which a draw bead is formed and a material for molding; deriving a first static frictional coefficient (μs1) according to equation 1 by measuring a first kinetic frictional coefficient (μk1) of the material through a press test of the mold and the material for molding; determining a type of lubricant to be applied to the material by comparing the first static frictional coefficient (μs1) with a preset standard static frictional coefficient of the material; applying the determined lubricant to the material, performing a press test with the mold, and measuring a second kinetic frictional coefficient (μk2) of the material coated with lubricant to obtain a second static frictional coefficient (μs2) according to equation 2; and determining whether a vertical load (N3) can be adjusted in order for a third kinetic frictional coefficient (μk3) value of equation 3 to be satisfied within a range of 0.54 to 0.74 by using the second static frictional coefficient (μs2), wherein a range of the vertical load N3, in which the third kinetic frictional coefficient (μk3) is satisfied within the range of 0.54 to 0.74, is derived when the vertical load (N3) falls within the adjustable range. According to the present invention, the method for designing molding conditions of a pressing die has the effect of minimizing molding failure. The equiation 1 is represented by: first kinetic frictional coefficient (μk1) = -0.260 + (0.804 x μs1) + (4.8 X 10^(-3)x N1), the equation 2 is represented by: second kinetic frictional coefficient (μk2) = -0.260 + (0.804 x μs2) + (4.8 X 10^(-3)x N2), and the equation 3 is represented by: third kinetic frictional coefficient (μk3) = -0.260 + (0.804 x μs2) + (4.8 X 10^(-3)x N3).
