Read an Excerpt
The impact or cold extrusion of metals is a " chipless machining"
process that can greatly reduce costs of material and labor
if properly applied. Within certain limitations in shape, some
parts can be produced by this process that often require only
trimming to length. On others, the secondary operations are
reduced greatly over those required for several of the competing
processes. Finally, certain components can be made that can be
produced by no other method.
Impact extrusion can be employed for the production of parts
from a wide range of metallic materials. In commercial production
at present are components produced from aluminum,
copper, lead, magnesium, tin, zinc and their alloys and various
steels. In the development stage are parts produced from less
common metals, such as titanium and molybdenum.
The aim of this book is to present a coordinated description of
impact extrusion. Its purpose is to present the information required
by an engineer to determine whether the process is
applicable to his products, and to assist the metallurgist in
selecting the metal to be used.
The book is based on personal experience, talks, and correspondence
with producers of components, and a search of the
free-world technical literature. It is divided into two parts.
The first deals with the underlying principles and the characteristics
of the process; the second, with the metals being extruded
and the products.
It is a pleasure to express my thanks to all those that assisted
in developing the theme. I feel particularly indebted to T. J.
Dolan, who prepared a number of the sketches; to my son,
Larry, who assisted in the preparation of the manuscript; and
to my wife, Helen, who prepared the graphs and many of the
sketches, and assisted in proofreading.
