Abstract
A toolset for forming a component from a powdered metal charge includes a die having two zones on the sidewall. Lubricant is applied to one of the zones. The powdered metal charge is initially compressed to an intermediate density and the lubricated zone of the sidewall brought into contact with the partially compressed charge. The charge is then further compressed to a final density.
