This chapter familiarizes readers with the design, configuration, and function of tooling and dies used to extrude aluminum alloys. It discuses basic design considerations, including the geometry, location, and orientation of die openings; allowances for thermal shrinkage, stretching, and deflection; and the length and profile of bearing surfaces. It outlines the steps and processes involved in die making, describes the selection and treatment of die materials, and examines the factors that influence friction and wear. It also discusses the general procedures for on-site die correction.

This chapter discusses many aspects of extrusion die and tooling, including the terminology and function of extrusion die and tooling, the types of dies, the fundamentals of die design, manufacturing, correction, material, and the surface treatments of die bearings and tribology in extrusion dies. It then presents the fundamentals and function of finite-element modeling simulation. The chapter describes the role of tribology and thermodynamics in the die bearing to control the flow and dimensional stability of extrusion exiting the die.
