How to Punch Holes in Aluminum Extrusions
Aluminum extrusions are widely used in manufacturing because they are lightweight, strong, and easy to form into complex profiles. However, their shaped geometry can make hole placement more challenging.
With UniPunch modular tooling, manufacturers can punch holes in aluminum extrusions quickly and accurately using existing presses or press brakes—eliminating many secondary operations.
The Extrusion Profile
The channels, legs and other formed features of aluminum extrusions make accurate hole punching difficult. UniPunch tooling is designed specifically for these types of shaped parts with holes located close to bends, edges, or structural features within the extrusion.
UniPunch AJ Series units and Feed Clearance Units are built for punching holes in up to 1/4″ thick aluminum. The pedestal die design maintains proper clearance and alignment, making it possible to produce accurate, repeatable holes without additional machining operations.
The pedestal die design allows holes to be punched in tight or hard-to-reach areas of extrusions. The UniPunch engineering team frequently modifies pedestal dies to fit complex profiles.
Improve Production Speed
Many manufacturers drill holes in aluminum extrusions, but drilling often requires additional setup, longer cycle times and deburring.
Punching with UniPunch tooling provides a faster and more efficient alternative:
- Reduced part handling
- Improved production speed
- Consistent hole placement
- Simplified fabrication for repeat jobs
With the right UniPunch setup, a long row of holes can be punched quickly, helping streamline production. Need to speed up your extrusion output? Contact us today!
