Aluminum Extrusion

Aluminum Extrusion is a plastic deformation process of a pre heated aluminum billet which is forced to flow by compression through a steel or ceramic die with an aperture of a smaller cross-sectional area than the original billet.


The aluminum extrusion process can be used to produce a variety of solid, hollow sections and profiles produced by extrusion through flat, porthole or bridge type dies.
Seamless tubes and seamless hollows sections must be produced using either hollow billets or solid billets using a piercing press and mandrel system.

 

There are two main methods of aluminum extrusion, these are:

 

Direct Aluminum Extrusion

With direct aluminum extrusion the preheated billet is placed in a heated part of the press called the container. Here, the billet is pushed through the die by ram pressure. The direction of the metal flow is in the same direction as the ram travel. During this process, the billet slides relative to the walls of the container, resulting in a necessary increase in ram pressure to overcome the friction between the billet surface and container liner.
Not all the aluminum billet is extruded. A percentage of the compressed billet, called the discard or butt is left at the end of the extrusion cycle. This is ejected from the press during its dead cycle operation, and ‘recycled’ at a later time. The extruded profile is then transferred on to the press’s handling system for further process.

 

Indirect Aluminum Extrusion

With indirect aluminum extrusion, the die located at the front end of a hollow stem moves relative to the container. The die is either pushed through the container or the container is pushed over the die. There is no relative displacement between the billet and the container liner. Therefore one advantage of the indirect extrusion process is that there is no friction, during the process, between the billet and the container liner. The metal flow is more uniform during indirect extrusion than direct. This usually relates to better section uniformity along its length.
A discard/butt is produced as with the direct process, which is handled in the same way. The extruded profile is again transferred on to the press’s handling system.

 

Cold Extrusion of Aluminum Alloy Parts

Aluminum alloys are well adapted to cold (impact) extrusion. The lower-strength, more ductile alloys, such as 1100 and 3003, are the easiest to extrude. When higher mechanical properties are required in the final product, heat treatable grades are used. The cold extrusion process should be considered for aluminum parts for the following reasons. High production rates—up to 4000 pieces/h—can be achieved. However, even when parts are large or of complex shape, lower production rates may still be economical. The impact-extruded part itself has a desirable structure. It is fully wrought, achieving maximum strength and toughness. It is a near-net shape. There is no parting line, and all that may be required is a trim to tubular sections. Surface finish is good. Impacts have zero draft angles, and tolerances are tight. Once impacted, sections can be treated in the same manner as any other piece of wrought aluminum. From a design standpoint, aluminum impacts should be considered: For hollow parts with one end partially or totally closed When multiple-part assemblies can be replaced with a one-piece design When a pressure-tight container is required When bottoms must be thicker than the walls or the bottom design includes bosses, tubular extensions, projections, or recesses When a bottom flange is required When bottoms, sidewalls, or heads have changes in section thickness Aluminum provides the characteristics of good strength-to-weight ratio, machinability, corrosion resistance, attractive appearance, and high thermal and electrical conductivity. It is also nonmagnetic, nonsparking, and nontoxic. Although nearly all aluminum alloys can be cold extruded, the five alloys of 1100, 3003, 6061, 2014, and 7075 are most commonly used. The alloys of 1100, 3003, 6061, 2014, and 7075 are in the order of decreasing extrudability based on pressure requirements. The easiest alloy to extrude (1100) has been assigned an arbitrary value of 1.0 in this comparison.
