Abstract
This 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 decoration section features
lengthy examinations of the following processes: painting, plating, vacuum,
metallizing, pad printing, hot stamping, silk screening, and the fill-and-wipe
process.
