Abstract

PURPOSE: To simply form recessions incapable of being deformed even at high temperatures by a method wherein a convexity is formed in a plastic plate by a hot stamping method, the covexity is cut off, and then the plastic plate is softened by heating to form a recession at the place where the convexity was present.
CONSTITUTION: A plastic plate 1 is softened by heating, convexities 1a are formed by a hot stamping method, and then the convexities 1a are cut off. And, the plastic plate 1 deprived of the convexities 1a is again softened by heating and recessions 1b are formed at the place where the convexities were cut off. Thus, a recession incapable of being deformed even at high temperatures can simply be formed in the plastic plate by a simplified process.
