Precision Metal Punching & Ironworker Services
Freedom Fabricators provides metal punching, notching, bar shearing, angle shearing, and flat-bar processing using a 93-ton dual-station AMADA Marvel Ironworker. This multi-workstation system allows our team to move efficiently between operations while producing accurate holes, cuts, and notches for custom fabrication and repeat production work.
AMADA Marvel Ironworker Capabilities
Our Made-in-the-USA AMADA Marvel Ironworker is a heavy-duty 93-ton, fully integrated, dual-operator machine with five workstations:
- Punching
- Round and square bar shearing
- Angle shearing
- Flat-bar shearing
- Notching
Because multiple operations are built into one machine, parts can move from one fabrication step to another without unnecessary tooling changes or additional handling.
Metal Punching Capacity
Punching with the Ironworker can be a fast alternative to drilling for suitable applications. The machine is listed with capability to punch holes up to 4-5/16 inches in a single stroke.
The adjustable electrical back gauge, alignment guides, and hold-down system help support repeatable positioning, square cuts, and reduced material distortion.
Bar, Angle, Flat-Bar, and Notching Capabilities
- Round bar shearing up to 2 inches
- Square bar shearing up to 2 inches × 2 inches
- Angle shearing up to 6 inches × 6 inches × 3/4 inch
- Straight and miter cuts on angle material within listed machine limits
- Flat-bar shearing up to 15 inches × 3/4 inch steel
- Flat-bar shearing up to 19 inches × 5/8 inch
- Notching of flat bar or angle up to 4 inches × 2 inches × 1/2 inch steel
Actual capacity depends on material type, thickness, geometry, and project requirements.
Materials We Process
Suitable punching and Ironworker applications may include:
- Carbon steel
- Stainless steel
- Aluminum
- Other appropriate plate, bar, and angle materials
Material grade, thickness, hole size, edge distance, and final geometry should be reviewed before production.
Benefits of Metal Punching & Ironworker Processing
- Fast hole production for suitable parts
- Multiple operations from one machine
- Reduced material handling
- Efficient repeat production
- Bar and angle processing
- Back-gauge positioning for repeatability
- Straight, miter, and notching operations within machine capacity
Punching vs. Drilling
Punching creates a hole in a single press stroke, which can make it very efficient for suitable sheet, plate, and bar-stock applications. Drilling removes material with a rotating cutting tool and may be better when a part requires blind holes, threaded holes, countersinks, counterbores, or more specialized hole-depth control.
Freedom Fabricators offers both processes and can determine which method best fits the material, geometry, hole size, tolerance, and quantity.
Industries We Serve
Our punching and Ironworker capabilities support:
- Structural fabrication
- Industrial manufacturing
- Commercial construction
- Equipment manufacturing
- OEM production
- Custom metal fabrication
Why Choose Freedom Fabricators for Metal Punching?
Freedom Fabricators can select from punching, drilling, shearing, laser cutting, waterjet cutting, and sawing based on the actual part requirements rather than forcing every job through one machine.
Our broader fabrication machinery and complete metal fabrication services allow parts to continue into bending, welding, machining, inspection, and finishing as needed.
Frequently Asked Questions About Metal Punching & Ironworker Services
What is an Ironworker?
An Ironworker is a multi-workstation fabrication machine capable of operations such as punching, bar shearing, angle shearing, flat-bar shearing, and notching.
What is the difference between punching and drilling?
Punching creates a hole in a single press stroke, while drilling removes material with a rotating cutting tool. Freedom Fabricators uses both processes depending on material, hole requirements, tolerance, and quantity. See our Drilling Services page for drilling capabilities.
What is the maximum hole size listed for punching?
The page lists capability to punch a hole up to 4-5/16 inches in a single stroke.
What bar sizes can the Ironworker shear?
The round and square bar stations are listed for sizes up to 2-inch round bar and 2-inch × 2-inch square bar.
What angle, flat-bar, and notching capacities are listed?
The page lists angle shearing up to 6 inches × 6 inches × 3/4 inch, flat-bar shearing up to 15 inches × 3/4 inch steel or 19 inches × 5/8 inch, and notching of flat bar or angle up to 4 inches × 2 inches × 1/2 inch steel.
How does the Ironworker help maintain repeatable cuts?
The machine uses an adjustable electrical back gauge, alignment guides, and an adjustable hold-down to support square, repeatable cuts while helping minimize distortion.
