Introduction

The design requirements of a plastic part are rarely specified by the user to a sufficient degree. The design method for processing and polymer selection almost always varies with the application. The checklist below is designed for use in the initial selection of the method and base polymer. It is a series of questions to ask and does not provide a rigorous design methodology.

This is really a set of "thinking points" that will hopefully enable you to capture the essentials of the requirements for the part.

Production

Mechanical

Assembly

Electrical

Thermal

* NB.These temperatures should include production, storage and transportation conditions.

Chemical

Optical

Environmental

Magnetic

Fire Resistance
