Bending and Shaping of Aluminum Extrusions (slides only)

Bending and Shaping of Aluminum Extrusions (webinar)

Many aluminum extrusion applications require some type of down-stream bending or shaping of the straight length extrusion. The ability to reliably create shaped components is a function of extrusion cross section (geometry, wall thickness, circle size, tolerance), part shape (length, bend radius, twist, bend angle), and material properties (alloy, temper, time). We will review the interaction of the physical characteristics of the extruded part with various bending processes and their effect on your ability to consistently produce shaped parts that meet your customer's specifications. We will consider standard bending processes (e.g., rotary draw bending and stretch bending) as well as more advanced forming processes (e.g., hydro-stretch bending and hydroforming).
