The most important factor to remember in the extrusion process is temperature. A circumscribed circle is the smallest circle that will completely enclose the cross section of an extruded shape. Extrusion size is measured by its longest cross-sectional dimension, i.e. Press size determines how large of an extrusion can be produced. The same principles apply to extrusions from aluminum billets but considerably more detailed and sophisticated technologies are involved. When Play-Doh® begins to emerge, it has effectively been "extruded". In an extrusion press, pressure is applied to the billet by the ram where the dummy block is attached to the end of the ram stem. Next, the Play-Doh® is inserted into the holding chamber and pressure is applied to the handle, which forces Play-Doh® through the shape. Think of the shape as the die and the color as the temper and alloy needed. ![]() The first step is to choose the desired shape and color. Think of the Fun Factory as the extrusion press, the handle as the ram, the shape bar as the die, and the Play-Doh® as the aluminum billet. To aid in understanding the aluminum extrusion process think about a Play-Doh® Fun Factory and how it works. Extruded material emerges as an elongated piece with the same profile as the die opening. Extrusion is defined as the process of shaping material, such as aluminum, by forcing it to flow through a shaped opening in a die.
