摘要:
A die for press-molding glass optical elements which can press-mold glass optical elements having high melting points and various shapes repeatedly, which includes a base material 11 having high strength on which a cutting layer 12 having heat resistance and free cutting machinability is formed. After cutting the cutting layer 12 into the desired shape with high accuracy, the die is coated with a surface protective film 13.
