CNC Bending & Folding Samples
Explore CNC bending and folding samples for stainless steel, aluminium, mild steel, sheet metal panels, brackets, enclosures, cabinets, frames, and custom fabricated parts. Our sheet metal bending service supports accurate angles, repeatable folds, clean edges, and small-batch to production fabrication for industrial, architectural, electronics, and equipment manufacturing projects in Singapore.
From flat blank to formed part
For most sheet metal projects, bending quality depends on more than the press brake itself. Flat pattern accuracy, material thickness, bend radius, flange length and bend sequence all affect whether the final part fits during assembly.
We review the drawing before production and combine laser cutting, CNC bending, deburring, welding, polishing and marking when the project requires a finished component rather than a single process.

Materials
Metals We Bend
12+ metal grades bent in-house. Each material has different yield strength and springback characteristics — our CNC programs apply material-specific compensation automatically.
Most Popular
Stainless Steel 304 / 316
0.5 – 8mm
High springback requires overbend compensation. Clean bend lines with no surface marking. Common for food, marine, medical and enclosure parts.
Structural
Mild / Carbon Steel
0.5 – 12mm
S275, S355. Predictable springback and cost-effective performance for structural brackets, frames, and cable trays.
High Demand
Aluminium 5052 / 6061
0.5 – 10mm
Low springback but crack-sensitive on tight radii. Used for enclosures, panels and lightweight brackets. Bend radius ≥ 1×T.
HVAC
Galvanised Steel (GI)
0.5 – 3mm
HVAC ducting, enclosures and cable management. Zinc coating remains at the bend for most applications.
Precision
Electro-Galvanised (EG)
0.5 – 2mm
Thinner zinc layer than hot-dip galvanised steel. Better surface finish for painted enclosures and precision sheet metal parts.
Formable
Aluminium 3003 / 1100
0.5 – 6mm
Highly formable and suitable for tight radii. Used for decorative panels, signage frames, lighting housings and complex bend sequences.
Decorative
Stainless Steel 430
0.5 – 4mm
Ferritic stainless steel for cost-sensitive applications. Common for kitchen equipment, architectural trim and decorative panels.
Electrical
Brass / Copper Sheet
0.5 – 4mm
Electrical bus bars, decorative components and connector housings. Soft tooling can be used to prevent surface marking on bright finishes.

Typical Applications
Where CNC Bending is Used
Sheet metal bending is the foundation of most metal fabrication — from precision enclosures to structural assemblies across every major Singapore industry.
Industrial Automation
Machine Enclosures & Control Panels
Electrical enclosure boxes, control panel backs, cable tray sections, and machine guards. Often cut and bent in the same order for dimensional consistency between mating parts.
Semiconductor & Electronics
Equipment Brackets & Chassis
Equipment mounting brackets, sub-chassis frames, shielding enclosures, and rack-mount panels. Tight angular tolerances maintain alignment for precision equipment installation.
HVAC & Building Services
Ductwork & Air Handling Components
Rectangular and square duct sections, transitions, and plenums in galvanised steel. Long bend capability handles full-length duct sides without seam welding.
Marine & Offshore
Structural Channels & Stiffeners
316 stainless steel angle, Z-section and hat-section stiffeners for marine equipment frames and offshore module support structures. Heavy plate up to 12 mm.
Architecture & Interiors
Façade Profiles & Feature Elements
Aluminium cladding returns, stainless steel feature strips, custom reveal sections and shadow-line trims. Long bends maintain straightness over 2–3 m architectural profiles.
Medical & Cleanroom
Equipment Housings & Trolleys
304 / 316 stainless steel enclosure bases, cart frames and instrument housing panels for medical and cleanroom environments. Radius corners reduce welded joints that can trap contamination.

Why Choose Us
What Makes Our CNC Bending Different
Bending looks simple — but springback, flange length minimums and bend sequence planning are where most jobs go wrong. We get this right the first time.
Cut and Bend from One Supplier
Our laser cutting and CNC bending are in the same facility. Laser-cut blanks go straight to the press brake — same day when needed. No dimensional shift from inter-supplier handoff, no re-quoting, no split delivery.
DFM Review Before First Bend
We check minimum flange lengths, minimum bend radii, bend sequence conflicts and tool clearance issues before production to avoid scrapped parts and reruns.
Material-Specific Springback Compensation
Stainless steel springs back more than mild steel; 6061-T6 is different from 5052-H32. Our CNC programs store material-specific overbend values built from production history.
Complex Multi-Bend Profiles in One Setup
Up to 12 sequential bends programmed with automatic back-gauge repositioning. Enclosure boxes, U-channels, Z-sections and hat profiles can be completed with angular consistency.

CNC Bending Questions
These are some of the common questions customers ask before sending drawings or requesting quotation.
What is the minimum flange length for CNC bending?
Minimum flange length depends on material thickness and the V-die opening used. As a general rule, the minimum flange is approximately 3× the material thickness for mild steel, and 4× for stainless steel and aluminium. For example, 2 mm stainless steel requires a minimum flange of approximately 8 mm. We check this on every drawing during DFM review and will flag any flanges that are too short before production.
What bend radius do you use as standard?
Our standard inside bend radius is equal to the material thickness (1×T) for mild steel and stainless steel. For aluminium, we recommend a minimum inside radius of 1.5×T to prevent cracking at the outer surface. Tighter radii are possible with dedicated tooling — please note this on your drawing. If no radius is specified, we apply our standard values and note them on the quote for your confirmation.
Can you bend parts that have already been laser cut with holes close to the bend line?
Yes, but holes within approximately 2× material thickness of the bend line will distort during bending. This is a sheet metal physics constraint, not a machine limitation. If your design requires holes near a bend, we’ll flag it during DFM review and can suggest moving the holes or adding relief cuts to prevent distortion. For tight-tolerance hole patterns near bends, we can also punch holes after bending.
What file format should I provide for CNC bending?
For bending, we prefer a 3D STEP file showing the finished bent part, plus a 2D DXF of the flat pattern with bend lines and angles annotated. If you only have a 3D model, our engineers can unfold it and generate the flat pattern. DXF drawings with bend annotations such as bend angle, inside radius and bend direction are also accepted. SolidWorks, CATIA, and Inventor files are fine — we can work from native formats.
Can you handle long parts — over 2 metres?
Yes. Our press brake has a 3200 mm bed, allowing single-hit bends up to 3.2 m long. For multi-bend parts with overall lengths over 2.5 m, we assess clearance per part geometry. Long architectural profiles in aluminium and galvanised steel are a regular part of our production. Please note overall unfolded dimensions when quoting so we can confirm machine clearance for your specific part.
Do you offer cutting and bending as a combined service?
Yes — this is one of our most common order types. We laser cut the flat blank and bend it in the same facility, often same day for standard orders. Combining both services eliminates inter-supplier dimensional variation, reduces lead time, and simplifies your purchase order. Just provide the finished 3D model and we’ll handle flat pattern development, cutting, and bending as a single job.
