Course Overview

Course in a Nutshell

With an ever increasing plastic parts content of products across a variety of industries, there is a critical need for a course on designing plastic parts for producibility, a niche this course seeks to fill. After an introduction to plastics, the course moves on to an in-depth discussion of designing for producibility and improved performance, tolerance considerations, injection molds, and molding. The full three-day course is recommended for those who wish to study the subject in depth, whereas a two-day, condensed version may suffice for the needs of those requiring a basic overview of the field.

 

Customize It!

We can customize this course to your team’s technical needs, usually at little to no added cost. While the primary audience of this course is product design engineers and their management, the course can also be tailored to the needs of marketing, technical sales, quality control/management, and procurement professionals, as well as others with interest in this subject.

A condensed two-day version of this course that presents the content in less depth is also available.

Schedule post-class follow-up consultation for continuing in-house implementation of the principles and techniques discussed in this course.

 

Audience / Prerequisites
