Aluminum extrusions can be manufactured in almost an unlimited combination of shapes and sizes. Aluminum tubing can have multiple holes, hole geometries and patterns. Profile Precision Extrusions has manufactured over 2000 different miniature aluminum extrusion designs in our 20+ years of business. One of our limiting factors is the size of extrusions we can manufacture. Miniature aluminum extrusions are generally defined as ones who fit into a 3.5” diameter circle. Our Design Tips webpage, http://profileprecisionextrusions.com/design-tips.html, has some suggestions to make your designs “extrusion friendly”.
Part size and weight is important to many of our customers. The lightest weight parts we make are extruded in 3003 alloy. We have extruded parts with .010” wall thickness in 3003, but our general rule of thumb is a minimum of .020” thick walls for that alloy. 6063 is another popular alloy. It is a bit harder to push through an extrusion die. We extrude parts as thin as .025” with 6063. 6061 is a little harder to extrude than 6063, and our generally don’t extrude wall thicknesses less than .030” with it. Don’t hesitate to ask if we can break our “rule of thumb” to make your design work.
Designs with uniform wall thicknesses throughout are the least expensive to make. They are the easiest for us to extrude, and least costly to produce. If your design has rounded edges it will be less costly to produce than one with very sharp corner radii. These rules apply to extruded tubing as well as extruded shapes.
Extrusion dies vary in cost depending upon geometry. Simple, solid shape dies generally cost between $500-750. Tubing dies are more completed to make and run between $1250-1750. Very complicated multi-hole designs can run over $4000. Compared to other forms of tooling, extrusion dies are very inexpensive.
