CNC Press Brake Bending
Accurate CNC press brake bending and folding for stainless steel, aluminium, mild steel and more. Angle tolerances from ±0.5°, complex multi-bend profiles, and in-house laser cutting upstream — one supplier from flat blank to finished part.
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.
What We Do
Our CNC press brake with back-gauge automation delivers repeatable bend angles across high-mix, low-to-medium volume sheet metal work — from simple L-brackets to complex multi-bend enclosures.

Max Bend Length
per bend; multi-bend parts up to 2500mm
Long panels, enclosure sides, and structural channels in a single bend — no repositioning or seam required.
0.5 – 12mm
Material Thickness
steel; 0.5–10mm aluminium
From thin 0.5 mm gauge sheet to 12 mm structural plate. Bending force auto-calculated per material and thickness.

max forming force — CNC back-gauge
160-tonne capacity handles thick stainless steel and aluminium structural sections without springback issues.
Up to 12
Multi-Bend Profiles

Up to 12 sequential bends per part. U-channels, Z-sections, box forms, and hat profiles programmed directly from your 3D model.
Auto
Springback Compensation
compensation per material + thickness
Material-specific springback offset applied automatically per alloy and temper. Consistent final angles without manual trial bends.
Materials
12+ metal grades bent in-house. Each material has different yield strength and springback characteristics — our CNC programs apply material-specific compensation automatically.
Stainless Steel 304 / 316
0.5 – 8mm
High springback — requires overbend compensation. Clean bend lines with no surface marking. Food, marine, medical enclosures.
Mild / Carbon Steel
0.5 – 12mm
S275, S355. Predictable springback, cost-effective for structural brackets, frames, and cable trays.
Aluminium 5052 / 6061
0.5 – 10mm
Low springback but crack-sensitive on tight radii. Enclosures, panels, aerospace brackets. Bend radius ≥ 1×T.
Galvanised Steel (GI)
0.5 – 3mm
HVAC ducting, enclosures, cable management. Zinc coating maintained at bend — no post-treatment required for most applications.
Electro-Galvanised (EG)
0.5 – 2mm
Thinner zinc layer than hot-dip. Better surface finish for painted enclosures and precision sheet metal.
Aluminium 3003 / 1100
0.5 – 6mm
Highly formable — tight radii possible. Decorative panels, signage frames, lighting housings. Excellent for complex bend sequences.
Stainless Steel 430
0.5 – 4mm
Ferritic SS for cost-sensitive applications. Kitchen equipment, architectural trim, decorative panels.
Brass / Copper Sheet
0.5 – 4mm
Electrical bus bars, decorative components, connector housings. Soft tooling used to prevent surface marking on bright finishes.

Sheet metal bending is the foundation of most metal fabrication — from precision enclosures to structural assemblies across every major Singapore industry.
Industrial Automation
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 mounting brackets, sub-chassis frames, shielding enclosures, and rack-mount panels. Tight angular tolerances maintain alignment for precision equipment installation.
HVAC & Building Services
Rectangular and square duct sections, transitions, and plenums in galvanised steel. Long bend capability handles full-length duct sides without seam welding.
Marine & Offshore
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
Aluminium cladding returns, SS feature strips, custom reveal sections and shadow-line trims. Long bends maintain straightness over 2–3 m architectural profiles.
Medical & Cleanroom
304 / 316 SS enclosure bases, cart frames, and instrument housing panels for medical and cleanroom environments. Radius corners bent in one hit — no welded joints to trap contamination.
Six steps, transparent at every stage. Most orders quote within 24 hours.
DXF, DWG, PDF, or STEP. We accept most 2D/3D formats.
We check tolerances, material fit, and flag any DFM issues before quoting.
Detailed quote within 24h — material, thickness, quantity, finish noted.
Cutting run on our CO₂ laser. Parameters selected per glass type and thickness.
Dimensional verification. First-off approval for new jobs; batch sampling for repeats.
Same-day dispatch for in-stock jobs. Local Singapore delivery or self-collect.
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.
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. Your flat pattern and bent part are dimensionally consistent by design.
We check every drawing for minimum flange lengths, minimum bend radii per material and thickness, bend sequence conflicts, and tool clearance issues. Catching these before production avoids scrapped parts and reruns — especially critical for stainless steel and 6061 aluminium which are less forgiving than mild steel.
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 — not from a chart. You get the right angle on the first part, not after three test bends.
Up to 12 sequential bends programmed with automatic back-gauge repositioning. Enclosure boxes, U-channels, Z-sections, and hat profiles completed without manual repositioning between bends — maintaining angular consistency across the entire sequence.
Understand when CNC bending is the right choice versus roll forming, stamping, or manual bending.

FAQ
These are some of the common questions customers ask before sending drawings or requesting quotation.
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.
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.
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.
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 (bend angle, inside radius, bend direction) are also accepted. SolidWorks, CATIA, and Inventor files are fine — we can work from native formats.
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.
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.
