ABSTRACT:
A method for making a sheet button panel assembly that can avoid wrinkles at boundaries of embossments and damages on a printed face of a decorative sheet. The method includes the steps of embossing the decorative sheet where only one mold contacts the portions of the decorative sheet to which embossments are formed and where the decorative sheet is heated, and injecting resin into a cavity to form a sheet button panel assembly in which the decorative sheet and the resin are made united. When embossing the decorative sheet, the decorative sheet is softened by heating and is less restricted because only one mold contacts the sheet. The decorative sheet is free of wrinkle and damage, in particular, no damages in printed face of the decorative sheet.
