Training in Plastics Technology 2E / Edition 2

by Walter Michaeli

Overview

This text/workbook provides a clearly written, comprehensive introduction to the major topics associated with plastics technology. It is divided into educational units, each covering a distinct subject area. Students can arrange these units to fit their individual educational objectives. Each unit has key questions at the beginning and review questions at the end, providing a useful means for the reader to work through the lessons with specific objectives in mind. The book not only enhances the reader's understanding of plastics and plastics technology but also facilitates independent, self-paced learning.

Editorial Reviews

At the behest of the Germany government, a team of engineering instructors produced in 1998 to support the country's extensive system of post-high school professional and technical training programs. It is here translated and adapted to fit into analogous programs in English-speaking countries. The 20 lessons need not be undertaken in sequence, and each merely notes which lessons should precede it. Compact discs as a plastic product are used as the example throughout. Answers to the review questions are provided. There is neither index nor bibliography. Annotation c. Book News, Inc., Portland, OR (booknews.com)
