Two mathematical models proposed by Avitzur and valid for axially symmetrical square extrusion are tested for their ability to predict the maximum power required in single as well as multiple hole extrusion. Comparison to experimental results obtained using plumber’s lead shows good correlation. The most significant parameter is shown to be the total area reduction. The velocity field in multiple hole extrusion—which by necessity must be nonaxially symmetrical—appears not to affect the power required for extrusion.
