As you will see on the examples on the following pages, the range of extrusion applications is almost endless. Few applications are too big - or too small. Almost any quantity may be practical if the shape fits the extrusion process.

Many of the applications included are past winners in the International Aluminum Extrusion Design Competition. Testimony that they are outstanding examples of the versatility of the extrusion process.

Perhaps more than any other forming process, aluminum extruding offers the designer a real creative challenge. With good design, extruded parts can serve both decorative and functional duties - hinges and fasteners can be made an integral part of the design, three or more parts can be combined into one extrusion and complicated shapes can be produced for a relatively slight increase in cost.

One of the key reasons for the growth of extrusion applications is that cost of dies is nominal and complex shapes almost always cost less extruded than they would formed, rolled or machined. A simple die for a solid shape for example, costs less than $500.

Lead times are rarely a problem with extrusions. The process itself is fast compared to most production processes and it takes only a few weeks to make a production die for solid shapes as well as hollow extrusions.

There are many custom extruders located through the U.S. prepared to help you with your design problems. When given a full description of a part's function and end use, the extruder can decide whether the shape is practical, which alloy you should consider and how much it will cost. Many extruders also offer fabricating and finishing services.

Now, let your mind roam . . .
