Book Chapter
Extrusion Die and Tooling
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 30 April 2025
DOI: 10.31399/asm.tb.aet2.t59420107
EISBN: 978-1-62708-487-1
Abstract
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.

Extrusion of Soft- and Medium-Grade Alloys
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 30 April 2025
DOI: 10.31399/asm.tb.aet2.t59420233
EISBN: 978-1-62708-487-1
Abstract
This chapter discusses the extrusion technology of soft- and medium-strength aluminum alloys. The relative extrudability ratings of some soft- and medium-grade alloys are given. The chapter presents useful extrusion parameters and their relationships associated with day-to-day production practices in the aluminum extrusion industry. Useful parameters discussed include: extrusion runout; extrusion pressure; ram or extrusion speed control; and butt or extrusion discard thickness control. The chapter provides fundamental approaches to introducing and developing the design of experiments (DOE) for the aluminum extrusion plant to improve overall productivity. It also focuses on heat treatment of aluminum alloys.

Extrusion
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 30 September 2023
DOI: 10.31399/asm.tb.stmflw.t59390284
EISBN: 978-1-62708-459-8
Abstract
This chapter deals with the mechanics and tribology associated with the extrusion of bars, sections, and tubes. It covers direct and indirect extrusion processes in detail and demonstrates the use of important equations, relationships, and measurements for determining pressure, force, material flow, friction, die wear, heat generation, and lubrication requirements. The chapter also provides information on hydrostatic, friction-assisted, and severe plastic deformation extrusion processes, discusses the cause of instabilities and defects, and explains how to select and apply lubricants to minimize friction and die wear when extruding steel, aluminum, copper, and refractory metals.

Publisher: ASM International
Published: 01 December 2006
DOI: 10.31399/asm.tb.ex2.t69980001
EISBN: 978-1-62708-342-3
Abstract
This chapter provides an overview of the basic principles and historic development of metal extrusion processes. It starts by illustrating the two major process categories: direct extrusion and indirect extrusion. It then briefly defines hydrostatic extrusion and the conform process. The history coverage addresses early patents for extrusion of lead at the turn of the 17th century up through the major process innovations in the 20th century.

EISBN: 978-1-62708-342-3
Abstract
This chapter begins with a description of the requirements of tooling and tooling material for hot extrusion. It covers the processes of designing tool and die sets for direct and indirect extrusion. Next, the chapter provides information on extrusion tooling and die sets for direct external and internal shape production and tools for copper alloy extrusion. Further, it addresses design, calculation, and dimensioning of single-piece and two-part containers and describes induction heating for containers. Information on static- and elastic-based analysis and dimensioning of containers loaded in three dimensions is provided. Examples of calculations for different containers, along with their stresses and dimensions, are presented and the manufacture, operation, and maintenance of containers are described. The chapter further discusses the properties and applications of hot working materials for the manufacture of extrusion tooling and of different extruded materials for the manufacture of extrusion tooling for direct and indirect forming.

Extrusion Die and Tooling
Available to PurchaseSeries: ASM Technical Books
Publisher: ASM International
Published: 01 March 2000
DOI: 10.31399/asm.tb.aet.t68260087
EISBN: 978-1-62708-336-2
Abstract
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.
