General Introduction

L6 Selection of Manufacturing Processes

As will be described throughout this text, there is often more than one method that
can be employed to produce a component for a product from a given material The
following broad categories of manufacturing methods are all applicable to metallic
as Well as nonmetallic materials:
a. Casting (Fig. I.6a): Expendable mold and permanent mold (Part Il).
