         <p>I
         am happy to endorse this second edition of <i>Designing
         Plastics Parts for Assembly</i> as a basic instructional tool for the
         product and plastics design engineer. Most Design Engineers have had
         little training in plastics design and even fewer have had training in
         designing for plastic part assembly. This has not stopped however, the
         rapid growth of plastics over the last forty years in the areas of
         automotive components and consumer products.</p> 
		 <p>Most
         expert product and plastic design engineers have learned their craft
         through on the job experiences. Where they have applied highly
         imaginative solutions to numerous joining and assembly problems;
         thereby, allowing their plastic parts to be cost effective and highly
         functional. Occasionally they have discovered the real governing design
         principles for plastic part assembly through initial failures of their
         design.</p> 
		 <p>The
         advantage of Paul Tres&#39;s book is that it spells out the governing
         fundamental principles for the various joining and assembly techniques
         for plastic parts. Thus, shortening the learning curve for the new
         plastics design engineer and saving time lost through redesign of a new
         part. As a result, plastic design engineers can build on the basic
         principles defined in this book through their work experiences and
         advance the state-of-the-art of plastic part assembly at a faster rate.</p> 
		 <p>Paul&#39;s
         book assembles, in a very readable form, a summary of the basic design
         principles learned over the years regarding plastic part assembly. The
         first four chapters provide a good review of the fundamental principles
         of plastics materials which a good design engineer must understand in
         order to produce efficient plastic part assemblies. Chapter five
         provides a good review of the various plastic welding techniques and
         good design practices for each type.</p> 
		 <p>The
         following three chapters provide excellent reviews of the design
         principles for components which require integral (living) hinges, press
         fitting, and snap fits. These design techniques are often employed the
         more efficient modern plastic part designs in commercial uses today. A
         good working knowledge of these techniques will be of great value to
         the product and plastic part designer in trying to develop designs that
         meet increasingly the more demanding functional requirements, while at
         the same time meeting increasingly more demanding cost constraints.</p> 
		 <p>I
         believe the modern product and plastics part designer will find Paul
         Tres&#39;s <i>Designing Plastic Parts
         for Assembly</i> a valuable reference for his future design
         assignments.</p>
