Plastic molding of articles including a hologram or other microstructure.

摘要

A technique for forming a mold to replicate large numbers of plastic articles, such as by injection or blow molding, wherein the mold contains a hologram or other microstructure for transfer to an outside surface of the molded article. The mold is made by electrodepositing a metal on a model (21,22) of the article to be molded. Before this deposition, the hologram or other microstructure (25,26) is formed on a surface area of the model by any one of several techniques. The result is a unitary mold piece in the shape of the article and having the hologram or other microstructure integrally formed on its inside surface.
