The first step in almost any aluminum extrusion fabrication process is precision cutting. This step is often followed by deburring and punching or forming. Extruders will typically have a range of saws to accommodate various cuts (square, miter, or angle), lengths, and cutting tolerances.

While it is often possible to cut extrusions without burrs, deburring may be required for specific parts and performance requirements, specifically where alloy, profile design, and blade selection aren’t ideal. Mechanical deburring with a brush or grinder is frequently used,. Tumble deburring in which quantities of small to mid-size parts are tumbled with an abrasive media to remove any burrs is also common.

Defining Processes 

Often, a following step will involve punching and/or forming the extrusion with mechanical presses and part-specific tooling to add holes, slots, or other functional features. For more complex parts, CNC machining may be employed.

Given the wide range of basic cutting, punching, and forming processes available, it is recommended that you discuss component requirements with an extruder. Find an Extruder can help locate an extruder with suitable fabrication capabilities.
