Panel benders form stainless to 1.2 mm at full bend length. That covers most cabinet and panel work, and none of the heavy worktop work. Here is exactly where the line falls.
A STON cast-iron frame panel bender forms stainless steel up to 1.2 mm at full bending length; a welded frame reaches 1,0 mm. That is the honest number, and it is lower than for cold-rolled steel because stainless work-hardens and springs back harder. It matters because stainless product specifications routinely sit at 1.5 mm and above — commercial worktops in particular.
Inside the window, a panel bender is excellent: cabinet doors, side panels, splash backs, shelf panels, hood panels and equipment housings in 0.8 to 1.2 mm are exactly the four-sided folded geometry it is built for, with the added benefit that vacuum pick-up never drags a brushed or mirror finish across a back gauge. Outside the window — 1.5 mm and thicker worktops, heavy frames, and deep-drawn sink bowls — the parts belong on a press brake or on press tooling, and no configuration option changes that. We identify which of your parts fall on each side of the line before quoting.

Most stainless cabinet and equipment panels are between 0.8 and 1.2 mm. The parts that fall outside are usually worktops and structural members — which is why nearly every stainless shop runs a press brake alongside.
Stainless work-hardens during forming and demands substantially more force than cold-rolled at the same gauge, which is why the panel bender limit is 1.2 mm rather than 2.0 mm. Specifications drift upwards easily — a 1.5 mm worktop looks like a small change from a 1.2 mm door, but it is on the other side of the machine boundary.
The same bend program that produces a correct angle in mild steel will under-bend stainless, and the error grows with thickness. Closed-loop servo control with rapid compensation adjustment along the bend line is what makes stainless angle repeatable across a batch, rather than something an operator re-establishes on each run.
Brushed, mirror and patterned stainless is specified by the customer and matched across a whole installation. A scratched panel is remade, not polished, at full material cost. Vacuum pick-up moves the blank in the air, protective film stays on through forming, and grain direction is controlled at the nesting stage.
For stainless work the first question is not volume — it is what proportion of your parts sit above 1.2 mm. That ratio decides the whole machine list.
This page exists because of one row. Read the stainless line, check it against your worktop specification, and bring the answer to the first call.

Stainless cabinet doors, side panels, splash backs, shelf panels, hoods and equipment housings at 0.8–1.2 mm, folded on all four sides, with a finish that must not be touched.
Commercial worktops at 1.5 mm and above at full bend length, deep-drawn sink bowls, heavy structural frames, and roll-formed profiles. Three different processes, none of them a panel bender.
Worktops, heavy frame members, thick brackets and any stainless part above 1.2 mm. In stainless fabrication the press brake is not a backup machine — for many shops it carries half the product.
Die Risikobeurteilung erfolgt nach EN ISO 12100; sicherheitsbezogene Steuerungsfunktionen wie die Unterbrechung des Lichtvorhangs und der Not-Halt sind gemäß EN ISO 13849-1. festgelegt. Hydraulische Abkantpressen, die in die EU geliefert werden, werden nach EN 12622. gebaut. Auf dem EU-Markt bereitgestellte Maschinen tragen die CE-Kennzeichnung gemäß Maschinenrichtlinie 2006/42/EG mit der zugehörigen technischen Dokumentation. Das Qualitätsmanagement ist zertifiziert nach ISO 9001, und bearbeitete strukturelle Toleranzen richten sich nach ISO 2768. For the finished product, EN 10088-2 covers stainless sheet delivery conditions and surface finishes, and EN 1672-2 sets hygiene requirements for food processing machinery including cleanable surfaces and edge design. Both apply to your product rather than to the machine, but the folded edge geometry they require is produced at the forming stage.
An den Maschinen bedeutet dies eine vollständig geschlossene Rückwandverkleidung, Schutzabdeckungen an allen herausragenden beweglichen Teilen, eine Laser-Schutzeinrichtung, die die Bewegung stoppt, wenn der Schutzbereich verletzt wird, einen Übertonnage-Schutz an Stanz-Nibbelmaschinen sowie eine Gitterlineal-Schräglasterkennung an Schwenkbiegemaschinen.
Stainless fabrication is the clearest case in sheet metal for needing more than one process. The split is decided by thickness and by whether the part is folded or drawn.
| CNC-Plattenbieger | CNC-Abkantpresse | Press tooling | |
|---|---|---|---|
| Stainless thickness | ≤1.2 mm at full length | Bestimmt durch Tonnage und Werkzeug | Set by the press and die |
| Typical stainless parts | Doors, side panels, splash backs, housings | Worktops, frames, heavy brackets | Sink bowls, drawn shells |
| Four-sided panels | Single clamping | 4 rotations | Nicht zutreffend |
| Finish protection | Vacuum pick-up, film retained | Manual handling each bend | Die contact |
| Springback control | Closed loop plus rapid compensation | Crowning plus operator | Built into the die |
| Tooling lead time | Custom knives, quoted with machine | Standard tooling | Long — dedicated die |
| Liefert STON dies? | Ja | Ja | Nein – ein anderer Prozess |
If most of your output is 1.5 mm worktops and drawn sink bowls, a panel bender is the wrong first purchase and we will say so. The right conversation in that case is about press brake capacity, not bending automation.
Die folgenden Zahlen veranschaulichen die Richtung und den Mechanismus der Veränderung. Die tatsächlichen Ergebnisse hängen von Ihrem Teilespektrum, der Chargengröße und dem Schichtmodell ab – vor der Angebotserstellung modellieren wir sie anhand Ihrer eigenen Zeichnungen.
| Artikel | Nur Abkantpressen | Panel bender cell |
|---|---|---|
| Contact with the finish | Dragged across the back gauge each bend | Keine – Vakuumaufnahme |
| Scrap from surface damage | The largest scrap category in stainless | Largely eliminated |
| Springback consistency | Re-established by the operator each run | Stored compensation values |
| Operators per large panel | 2 | 1, or unattended with loading |
| Angle consistency across a batch | Abweichungen je nach Bediener und Schicht | ca. ±0,5°/m |
| Changeover between cabinet sizes | Werkzeugwechsel und Nullpunkt-Einstellung | Program recall |
| Parts above 1.2 mm stainless | Handled | Stay on the press brake |

On stainless, automation is justified by scrap as much as by labour. Native interface on every panel bender, vacuum pick-up that never touches the finished face, compatible with most robot brands.
Traversensystem ansehen →Founded in 2006 and headquartered in Qingdao, one hour from major export ports and the airport. Casting, heat treatment, machining, welding, assembly and inspection all happen inside our own 20,000㎡ factory. That is why a configuration change for a stainless panel cell does not become a six-month subcontracting problem.
Stainless material cost per part is high, so a machine problem becomes a scrap problem quickly. Fast diagnosis matters more here than in almost any other sheet metal sector.
