Thickness by material
One of the stated figures was for stainless steel, the other named no material. Mild steel, stainless and aluminium each get a different limit. Ask for all three at full length.

A panel bender is sold on speed, but it only pays when your parts fit its narrow window of thickness, box height and blank size, and most listings do not state that window at all.

One of the stated figures was for stainless steel, the other named no material. Mild steel, stainless and aluminium each get a different limit. Ask for all three at full length.
The upper tool must change length for every part. Automatic adjustment runs without a person; manual segments bring the operator back, and most of the speed goes with them.
Maximum bending height decides the deepest box you can make. The minimum part size decides whether small brackets fit at all. One listing stated a 300 x 300 mm minimum.
Axis counts in listings ran as high as 21. What matters is whether the sheet rotates by itself, and how it is loaded and unloaded.
Offline programming from your 3D files, in your language, with a licence you own. Without it the machine waits while someone types each part in.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

| Require this | A pass looks like |
|---|---|
| Bend five of your own panels, including the thickest stainless one, in one session without touching the tooling by hand. | Every flange and angle inside your drawing tolerance, and tool changes done by the machine. |
| Time a full part change from one of your panels to another, from the program call to the first good part. | The time is recorded in the FAT report and matches what the quote promised. |
| Program a new part from your 3D file on the offline software in front of you. | Program runs first time with no manual sequence edits at the machine. |

A CNC press brake, which bends thicker material and more varied shapes with changeable tools.
A roll forming machine, which makes that profile continuously from coil.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.
07
Every machine we source in this area is on the Metal & CNC page. How a project runs, stage by stage, is on how it works, and what it costs is on pricing.
Straight answers
Many Chinese machines use the same servo brands. The gap is software maturity, tooling automation and service in Europe. Test all three on your own parts.
How many units they have delivered and running, whether they write their own software, and whether you can speak to a user of the same model.
A Declaration of Conformity naming the directives and standards, the technical file behind it, and a manual in your language. A CE mark on a brochure proves nothing.
If you import it yourself, you are: you check the conformity documents and put your name and address on the machine or its papers.
