Revolutionizing Aluminum Mullion Fabrication
In the world of architectural glazing and curtain wall production, efficiency is determined by how much secondary handling you can eliminate. Our Aluminum Mullion Hole Punching Machine is engineered to replace time-consuming manual layouts and slow CNC drilling cycles with a high-speed, precision punching solution.


Why Punching Outperforms Traditional Machining
| Feature | Punching Machine | CNC / Manual Drilling |
|---|---|---|
| Cycle Time | Instant (Single Stroke) | Slow (Hole-by-Hole) |
| Setup Complexity | Fixed Die / Flip-Stops | G-Code / Manual Layout |
| Consistency | Mechanical Repeatability | Variable (Human Error) |
Key Production Benefits
Simultaneous Multi-Hole Patterns
Our machines allow you to punch as many holes as required in a single pass. Whether you are working with vertical mullions, horizontal rails, or filler extrusions, you can hit complex patterns across multiple planes without rotating the part.
Elimination of Manual Measurement
By utilizing pre-set flip stops, the operator simply slides the extrusion into the die set and hits the start button. This eliminates the "measure, mark, and check" cycle that slows down traditional shop workflows.

Streamlined Operational Workflow
- Insert: Place the mullion or filler into the customized die nest.
- Align: Slide against the flip-stop for precision hole placement.
- Punch: Activate the machine to instantly create all required openings.
