Metal Extrusion

This chapter develops in readers the skill of extruding metals to manufacture good quality parts both with round and complex cross-sections. Firstly, the advantages and applications of extrusion are reviewed, followed by presenting a classification chart of extrusion processes. Cold and hot extrusions are compared, including their advantages. Direct extrusion and indirect extrusion operations are explained with the aid of labeled diagrams, including tube manufacture. Hydrostatic extrusion, lateral extrusion, and impact extrusion operations are also described. Finally, the engineering analysis of extrusion is presented with the aid of a diagram and mathematical models. This chapter contains 21 worked numerical examples, 9 diagrams, 12 formulae, 9 problems, and 10 MCQ with their answers given at the end of the book.
