Abstract

PURPOSE:To form character and pattern sections on a molding body strongly and finely by a method wherein tapered holes successively tapered toward character and pattern forming sections are bored to the molding body and molten resin is injected from the tapered holes. CONSTITUTION:Tapered holes 11 successively tapered are bored over the surface sides 10a from the back sides 10b of the character and pattern forming sections 15' of a molding body 10. Character and pattern sections 15 are molded in such a manner that the character and pattern forming sections 15' at the surface sides 10a are mounted to a drag 20 of a mold so as to be located at character and pattern cavities 21, and molten resin 14 is filled in the character and pattern cavities 21 through the tapered holes 11. Thus, the character and pattern sections can strongly be formed on a molding body finely.
