| Specification | Value |
|---|---|
| Max bending force | Standard CNC press brake |
| Max material thickness | 1/4 inch (6.35mm) mild steel |
| Max bed width | 10 feet (120 inches) |
| Materials | Mild steel, 304/316 stainless, aluminum 5052/6061 |
| Bend types | 90°, acute, obtuse, hem, offset, multi-stage |
| Oversize handling | Parts over 60" require two operators (2× labour multiplier) |
| Tolerance | ±0.010" on bend angles, ±0.015" on flange lengths |
Materials & Bend Allowances
| Material | Max Gauge | K-Factor | Min Flange |
|---|---|---|---|
| Mild Steel (A36, CRS) | 1/4" (6.35mm) | 0.35-0.45 | 4× material thickness |
| 304 Stainless | 3/16" (4.76mm) | 0.38-0.48 | 5× material thickness |
| Aluminum 5052 | 1/4" (6.35mm) | 0.33-0.43 | 4× material thickness |
| Aluminum 6061-T6 | 3/16" (4.76mm) | 0.30-0.40 | 6× material thickness (brittle — use bend radii) |
K-factors are approximate — send us your material spec for exact bend deductions. T6 aluminum may require annealing for tight-radius bends.
What Press Brake Forming Costs
- Setup: $30 flat per job — includes tooling selection and program
- Forming labour: $130/hr standard rate. Oversize parts (>60") double at 2× (requires two operators)
- Typical estimate: Simple brackets with 2-4 bends: $15-60 each in small quantities. Complex enclosures with 10+ bends: $80-300 each
If your parts are already being laser-cut by us, forming is quoted as a secondary operation — no separate setup charge.
Frequently Asked Questions
Do you need a flat pattern or a 3D model?
Either works. A flat pattern DXF with bend lines is fastest — we read the bend angles and flange lengths directly. A 3D STEP model also works — our AI analyzes the formed geometry. If you only have a formed-view drawing, upload it with material and thickness noted and we'll figure out the flat pattern.
What's your minimum bend radius?
Standard practice is 1× material thickness for mild steel and aluminum, 1.5× for stainless. Tighter radii are possible but risk cracking — especially on 6061-T6 aluminum. We'll flag any bends that look problematic before we quote.
Can you bend parts that are already laser-cut?
Yes — and we prefer it that way. Upload your laser-cut DXFs and we'll quote cutting + forming as a single job. If you already have cut blanks, we'll form them. One quote, one shop, one delivery.
