Abstract:The design of forming die and manufacturing engineering for CRT shadow mask was described and the flow chart was given. The mathematical expression for the surface profile was put forward based on the analysis on the mechanism of forming for shadow mask. A spec/al surface measurement device for shadow mask was used to directly measure the products made by the forming die in order to determine the amendments for each part of the die and to get better effect. Desirable result was achieved in the design of forming die for shadow mask of one color CRT.
Keywords:color CRT   shadow mask   die design   mathematical expression
