Punching is the step in aluminium profile fabrication where functional openings — lock holes, weep holes, hinge points, corner joints, and drainage slots — are created in the profile after it’s been cut to size (see our guide to aluminium cutting machines). Get this step wrong, and even a perfectly cut profile won’t assemble correctly or perform as intended once installed.
APH Machine India manufactures pneumatic aluminium section punching machines in a range of die configurations, built for the precision and consistency aluminium window, door, and facade fabrication demands. This guide covers the full range, what each hole type is for, and how to choose the right configuration for your production line.
What Does an Aluminium Punching Machine Actually Punch?
Aluminium punching machines are used to create several distinct types of openings in a profile, each serving a specific function in the finished window, door, or facade system:
- Lock holes — openings for door and window locking hardware
- Weep holes — small drainage openings that allow water to escape from the profile, preventing moisture buildup
- Corner joint holes — used in the assembly and alignment of frame corners
- Hinge and hardware mounting holes — positions for hinges, handles, and other fittings
- Mortise slots — rectangular openings for certain hardware and locking mechanisms
Each of these requires precise, repeatable positioning, which is why a dedicated punching machine, rather than manual drilling, is standard in serious fabrication operations.
Pneumatic vs Hydraulic: The Core Decision
Before choosing a specific machine, the first decision is which power system fits your profile types: pneumatic or hydraulic.
Pneumatic punching machines use compressed air to drive the punch, offering faster cycle times and lower cost, well suited to standard-thickness profiles.
Hydraulic punching machines use pressurized fluid to deliver smoother, higher force, better suited to thick or thermal-break profiles where a sudden pneumatic impact risks crushing the profile’s hollow chambers.
For the full breakdown, including which to choose based on your profile type, see our detailed comparison guide below.

Our Punching Machine Range
Pneumatic Aluminium Section Punching Machine
Available in single die (1D), double die (2D), and four die (4D) configurations, our pneumatic punching machine is built for accurate, repeatable hole and slot punching on standard aluminium window and door profiles.
Die configuration guide:
| Configuration | Best For |
|---|---|
| Single Die (1D) | Lower-volume production, single hole type per cycle, lowest cost entry point |
| Double Die (2D) | Moderate volume, two hole types processed without re-tooling between cycles |
| Four Die (4D) | Higher-volume production, multiple hole types in fewer handling steps |

Hydraulic Punching Machines
For thicker or thermal-break profiles where higher, smoother punching force is needed, hydraulic punching is typically the better fit. Our team can advise on the right hydraulic configuration for your specific profile requirements.
How to Choose: A Quick Framework
| If your priority is... | Consider... |
|---|---|
| Standard window/door profiles, higher cycle speed | Pneumatic Punching Machine |
| Thick or thermal-break profiles, higher force needed | Hydraulic Punching Machine |
| Lower production volume, single hole type | Single Die (1D) configuration |
| Multiple hole types without re-tooling | Double or Four Die (2D/4D) configuration |
| Highest throughput, multiple hole types per cycle | Four Die (4D) configuration |
Applications
Aluminium punching machines from this range are used across:
- Window and door fabrication — lock holes, weep holes, hinge points
- Curtain wall and facade systems — corner joints, structural fastening points
- Sliding window and door systems — track and roller hardware openings
- Aluminium formwork — see our dedicated Aluminium Formwork Machinery range for formwork-specific hydraulic punching machines

Frequently Asked Questions
What's the difference between single die, double die, and four die punching machines?
The number refers to how many punching dies the machine can process in a cycle without re-tooling. A single die machine handles one hole type at a time, while a four die machine can process multiple hole types with fewer handling steps, suited to higher-volume production.

Do I need a hydraulic punching machine, or is pneumatic enough?
It depends on your profile thickness. Standard window and door profiles are usually well served by pneumatic punching. Thicker or thermal-break profiles, common in energy-efficient and curtain wall systems, typically need the smoother, higher force a hydraulic system provides to avoid deforming the profile.
What hole types does a punching machine typically create?
Lock holes, weep holes (for drainage), corner joint holes, hinge and hardware mounting holes, and mortise slots are the most common, depending on the profile system and hardware being installed.
Can one punching machine handle multiple hole types?
Yes, double die and four die configurations are specifically designed to process multiple hole types without needing to re-tool the machine between cycles, which speeds up production for profiles that need several different punches.
Where are APH Machine India's punching machines manufactured?
All machines are designed and manufactured in-house at our ISO 9001:2015 certified facility in Vadodara, Gujarat, India.
