Plastics Finishing
This Plastics Finishing program includes information on the array of plastics finishing processes, arranging them into four categories: degating, deflashing, cleaning, and decorating. The Degating section includes segments on manual degating and the various automated tooling devices. The Deflashing section covers the cutting and trimming, media blasting and cryogenic deflashing processes. The Cleaning segment features the ways in which contaminants infiltrate the molding process and how parts are cleaned for secondary decorative operations. The Decorating section features lengthy examinations of the following processes: painting, plating, vacuum metallizing, pad printing, hot stamping, silk screening, and fill-and-wipe.
