You do not get to choose your parts. Here is how to buy capacity for a mix you cannot predict — starting with why a panel bender is usually the wrong first machine.
A job shop is defined by a mix it does not control: one-off brackets alongside batches of fifty, 0.8 mm enclosure panels alongside 8 mm structural plate, and drawings that arrive the same week they are due. That rules out most dedicated automation. The three machines that actually earn their keep are a Faserlaser for tooling-free blanking across every thickness, a CNC-Abkantpresse for forming anything the laser cuts, and — once repeat work builds up — a CNC-Revolverstanzmaschine for parts with dense repeating hole patterns.
A panel bender is usually the wrong first purchase for a job shop, and we say that as a company that manufactures them. Panel benders excel at flat panels folded on all four sides in 0.5 to 2.0 mm, repeated many times. A shop whose typical order quantity is under twenty pieces will spend more time programming than bending. The sensible sequence is laser, press brake, turret punch — and a panel bender only when a specific customer's repeat panel work justifies it on its own.

Industry pages start from a part. A job shop cannot, so the buying criteria are structural rather than geometric. These are the eight we work through with contract fabricators.
On an order of ten parts, programming, tooling and first-article proving can exceed the machining time several times over. This is why tooling-free processes matter more in a job shop than raw cutting speed — a laser that needs no tooling and a press brake with fast clamp changes beat a faster machine that needs a die order.
Shops size machines against typical work and then subcontract everything thick or long, giving away margin on exactly the jobs that carry it. Press brakes from 63 t to 320 t and 1500 to 4100 mm exist so that the extremes stay in house. Deciding which extremes are worth owning is the actual purchasing question.
A panel bender, a coil line or a robot cell all reward repetition. In a shop with genuinely mixed work they become expensive floor space. The right sequence is to earn the repeat volume first, then automate the part families that have stabilised — which is a conversation we would rather have honestly than sell into.
Almost every successful job shop we supply has followed this order. Skipping ahead is the most common capital mistake in the sector.
A job shop buys range, so the numbers below are capacity envelopes rather than a single specification. The rows that matter are the ones covering your extremes.
| Parameter | Fiber laser | CNC-Abkantpresse | CNC turret punch |
|---|---|---|---|
| Power / capacity | 1–6 kW | 63 t to 320 t | 300–400 kN |
| Working length | 3015 to 6025 formats | 1500 to 4100 mm | X 2500 mm, secondary to 5000 mm |
| Materials | Carbon, stainless, galvanised, aluminium | All, within tonnage | Sheet within tooling capacity |
| Tooling lead time | Keine | Standard tooling, fast change | Erforderliche Stanz- und Matrizensätze |
| Best batch size | 1 to any | 1 to any | Medium to large repeats |
| Accuracy | Fine kerf, burr-free | Grating ruler, closed loop | ±0,1 mm |
| Umformvorgänge | Nur Schneiden | Bending only | Louvres, ribs, embossing |
| Footprint | 4.5 × 2.6 m to 16 × 4.1 m | 2.0 × 1.6 m to 4.8 × 2.1 m | approx. 5.2 × 5.0 m |
| Stromversorgung | 3φ 380 V, 60–120 kVA by laser power | 3φ 380 V | 380 V ±5%, 0,55 MPa Druckluft |
Unpredictable mix, small batches, wide thickness range and short lead times — handled by tooling-free cutting and flexible forming, with punching added as repeat work accumulates.
Buying a panel bender, a coil line or a robot cell as a first machine for genuinely mixed work. These reward repetition, and a job shop's defining characteristic is that it has none yet.
The press brake is not the fallback here — it is the core forming machine. The question for a job shop is how many, at what tonnage and length, not whether to keep one.
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. Hydraulic press brakes are built against EN 12622, and general dimensional tolerances on contract work are usually specified to ISO 2768 medium or fine class — worth agreeing with each customer in writing, because it is the most common source of contract disputes in fabrication.
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.
For a contract shop this is a utilisation question rather than a technology question. The right answer changes as your repeat work grows.
| Fiber laser | CNC turret punch | Punch-laser combined | |
|---|---|---|---|
| One-off and prototype work | Best — no tooling | Limited to tooling library | Good |
| Repeating hole arrays | Slow — pierces each hole | Fastest | Fastest |
| Complex contours | Best | Limited | Good |
| Forming (louvres, ribs) | Nein | Ja | Ja |
| Thick material | Up to laser power | Tonnage limited | Mixed |
| Stellfläche | Mittel | Mittel | approx. 40% less than both separately |
| Best time to buy | First machine | When repeats build | When mix genuinely needs both on one part |
| Liefert STON dies? | Ja | Ja | Ja |
If a single customer's repeat panel work grows large enough to fill a machine on its own, that is the point to look at a panel bender — not before. We would rather tell you to wait than sell a machine that spends its life being programmed.
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 | Buying for the average part | Owning the range |
|---|---|---|
| Thick and long work | Subcontracted, margin given away | Retained in house |
| Lead time control | Dependent on a supplier's queue | Own scheduling |
| Quote win rate on mixed packages | Loses jobs that mix thin and thick | Quotes the whole package |
| Setup cost per small order | Doubled by external handling | Single setup in house |
| Quality accountability | Split across suppliers | Single point |
| Kapitalbedarf | Niedriger | Höher |
| Right answer | Depends on how often the extremes appear — which is the calculation we build with your job history | |
Amortisationslogik, die wir mit Kunden verwenden: (freigesetzte Jahresarbeitskraft + Reduzierung von Nacharbeit und Ausschuss + zusätzlicher verkaufsfähiger Ausstoß) ÷ Kosten der installierten Anlage. Wir erarbeiten dies mit Ihren tatsächlichen Zahlen, statt eine Kennzahl zu veröffentlichen, die nicht zu Ihrem Werk passen würde.

Worth considering only once a specific part family has stabilised at volume. Four-sided panels in 0.5–2.0 mm, program-driven, one operator or none — excellent economics on repeats, poor economics on one-offs.
Pressarmtyp anzeigen →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 mixed-work fabrication shop does not become a six-month subcontracting problem.




A contract shop has no buffer stock and no second machine to fall back on. Uptime is the whole business case, which is why response time and spare parts availability belong in the purchase decision rather than after it.
