ADVANCED TECHNOLOGIES FOR HIGH CONTRAST COLOR LASER MARKING OF PLASTICS

摘要

The newest generation of laser material science and hardware/software is driving strong industry demand for indelible, high speed laser marking processes to replace conventional ink printing. This paper presents a "total solutions" methodology for achieving unprecedented marking contrast quality and color laser marking of plastics via concomitant engineering of: 1) laser additive material science, 2) primary molding operations, 3) laser/software technology, and 4) systems integration. The first of its kind laser pigment to receive U.S. Food and Drug Administration (FDA) approval for use in laser processes is introduced as well as techniques to achieve high speed vector marking of alphanumeric text, graphics and product security codes.
