Abstract
Method for making isostress contoured dies by providing a cavity containing multiple vertical supports. A flexible material is tensionally secured across the top of the cavity to contact the supports and pneumatically deformed to assume an isostress contour. A form setting material is deposited and cured against the isostress contoured flexible material. The cured material may then be used directly as a die or as a die-forming master pattern.
