    摘要： A method of forming a slush mold and a synthetic resin skin utilizing the slush mold. The method includes the steps of roughing a foamed synthetic resin surface to define a prototype having a plurality of irregularly spaced and irregularly sized recesses, forming a metal mold to have a molding surface accurately complementary to the prototype surface and molding a skin of synthetic resin against the molding surface of the metal mold. The recesses preferably have a cross section dimension in the range of approximately 170 to 500 microns and a depth in the range of approximately 8 to 133 microns. Narrower preferred ranges are disclosed. The surface preferably has a regular unbiased variance of less than approximately 300 microns and preferably less than 200 microns.
