Maximum online flat blank fit
120 in
Maximum online bend length
170 ton
Maximum press brake tonnage online
10 files
Maximum upload batch size
Capability Snapshot
What the public quote system is designed to handle.
These are the limits that matter most before a buyer uploads a file.
Laser quoting path
- Flat parts are quoted with the standard laser pricing model.
- This includes DXF parts and flat STEP parts.
- Material, thickness, quantity, cut length, and pierces drive the quote.
Formed STEP path
- Bend count, weight, blank estimate, and brake fit are evaluated.
- Brake setup and bend labor are added when the part is formable online.
- Rows that fall outside the rules switch the order to manual review.
Limits Table
Current online quoting limits and decision points.
| Category | Current online rule | What happens if it is exceeded |
|---|---|---|
| Upload types | DXF, STEP, and STP | Unsupported files are rejected before quoting. |
| Upload count | Up to 10 files per upload batch | The user must split larger groups into multiple uploads. |
| Flat blank fit | One side must be 59.00 in or less and the other 119.25 in or less | The part goes to review if it does not fit the online sheet rule. |
| Brake length | Maximum 120 in bend length online | The formed part is flagged for manual review. |
| Brake tonnage | 170-ton online working limit; TruBend 5170S rated at 187 tons | The formed part is flagged for manual review before the working limit is exceeded. |
| Minimum laser hole | Hole diameter must be at least 0.5× material thickness | Smaller holes are identified by number and sent to shop review. |
| Hole to bend | Hole-edge clearance to the bend centerline must be at least half the selected V-die opening | Close holes are flagged because they can distort during forming. |
| Minimum flange | Outside flange must be at least 0.7493× the selected V-die opening | The exact bend and bottom die are shown for shop review. |
| Slots, webs, and edge tabs | Default minimums are 0.5 times thickness for slot width and 1.0 times thickness for webs and edge material | Narrow geometry is identified by feature and routed to review. |
| Bend relief | Internal bend endpoints need relief at least 1.0 times thickness wide and half the selected V-opening deep | Partial bends without a detected relief are routed to review. |
| Tool load | Required tons per inch must remain below the configured lowest marked capacity in the tooling stack | The exact bend load is shown for tool verification. |
| Bend tooling | Every bend must map to an available bottom die; only specific tight-return geometry requires an additional forming review | Ordinary multi-bend pans remain eligible for instant quoting. |
| Taps, countersinks, and inserts | Hole size, tap engagement, countersink depth, insert thickness, and insert edge distance are checked | Secondary operations outside the configured rules are routed to review. |
| Modeled thickness | .030 in through 1.000 in across the three online materials | Material under .060 in receives the configured thin-gauge cost premium and automatically adds 3 business days to the ship estimate. |
File Prep
How to get the cleanest online result.
These guidelines are written so both CAD-savvy users and occasional buyers can follow them.
DXF recommendations
- Use inches if possible.
- Remove duplicate or overlapping geometry.
- Close all cut profiles.
- Convert text or splines to outlines when needed.
STEP recommendations
- Export the final solid with the correct material thickness.
- Use STEP or STP when you want formed-part analysis or 3D review.
- Flat STEP parts can still be quoted as laser-cut parts.
- Keep the model clean and representative of the actual part you need built.
When review is normal
- Very large formed parts.
- Brake tonnage beyond the online machine limit.
- Thicknesses or geometry the system cannot confidently classify.
- Parts that need estimator judgment before pricing.
Notes For Engineers
What the formed-part logic is looking for.
This is the technical side of the public flow without making the page read like internal documentation.
Flat STEP behavior
If the uploaded STEP model is flat and has no bends, it should be treated as a laser-cut part, not as a failed formed-part analysis.
Formed STEP behavior
For formed parts, the system estimates bend count, blank size, weight, and brake requirements before deciding whether the row remains instant-quotable.

Use The Actual Flow
The quote page is the fastest way to see how your part will be handled.
Upload the real DXF or STEP file and let the live row state, preview, and order summary show whether it is a flat laser part, a formed STEP part, or a review item.
