VENTING OF ELECTROFORM REFLEX INSERTS BY LASER DRILL

摘要

A unitary electroplated reflex insert preferably made of high nickel alloy, useful in completing a molding assembly for making plastic retrodirective reflectors. The insert has a patterned surface contoured with a plurality of multi-faceted cube-corner projections arranged with adjacent edges of commonly joined facets defining female apices; microbores are constructed through said female apices such as by laser beam drilling to provide a venting system.
