Course Title: Industrial Finishing and Decorating

20 Professional Development Hours/2.0 CEUs

Course Description: The Industrial Finishing and Decorating course explains many of the ways in which plastic parts may be painted or finished, including painting, pad and screen printing, hot stamping, insert molding and chrome plating. The equipment and processes are described as well as the many steps involved in the chrome plating process. The course ends with a discussion of weathering processes and test methods.

Overall Course Objectives:

Understand the in-mold decorating, pad printing, screen printing and hot stamping methods for finishing plastic parts.
Learn about key paint concepts, application methods and applications equipment.
Gain knowledge about the weathering of plastics and methods measuring weathering resistance.

Course Content:
