What is CNC bending?

Bending turns a flat part into a three-dimensional one. The CNC press brake controls the position, depth and sequence of every bend, so part number one hundred comes out like the first.

The decisive part of bending, though, happens before the machine: the flat pattern. Engineering works out how much material each bend consumes for that material and radius, and cuts the blank to that size. Get this wrong and the bent part will miss the drawing dimensions no matter how accurate the press brake is.

It is the natural next step after sheet laser cutting, and we do it in the same plant so both stages stay in step.

Materials and thicknesses for CNC bending

Metals and sheet thicknesses we work with as standard. If your industrial project needs a material that is not in the table, say so in your enquiry and our engineering office will confirm whether we can handle it.

This service works with the same materials and thicknesses as the rest of the plant. The full table is on the Sheet metal laser cutting page.

CAD file formats accepted for quoting

  • DXF
  • DWG
  • STEP / STP
  • PDF
  • STL
  • IGS / IGES
  • PNG
  • JPG

With DXF, DWG or STEP we work straight from your file geometry: no need to redraw the part, and the quote comes back sooner.

We do more than check the drawing: we advise you on nesting (how the sheet is used) so you get the lowest possible price per part before anything is cut.

How our engineering office works

If you would rather not fill in the form, send the drawing straight to cata@catagermans.com.

Confidential handling. Your drawings are only used to prepare the technical assessment and are not shared with third parties. If you need a signed non-disclosure agreement, send it over.

Why work with Catà Germans

Every process under one roof
Cutting, forming, machining, welding and finishing in the same plant. We handle the whole logistics side so you receive the parts palletised and protected at your own factory, anywhere in Catalonia and the surrounding area, on the agreed lead time.
In-house engineering office
We review the drawing before manufacturing and prepare production from CAD/CAM. If something does not add up, we ask you instead of interpreting it ourselves. And if what you have is a sketch or a question, we will help with that too: advice is part of the service.
From drawing to finished product
Some finishes, such as painting or zinc plating, are done with specialist workshops. We handle the coordination and deliver with our own fleet: a single order and a part ready to fit.
Raw material in stock
We keep sheet and tube permanently in stock, so many standard jobs can start without waiting for material.
Over 65 years of the trade
A family business founded in 1958, specialised in industrial subcontracting of metal parts. You deal directly with the people who make the part.

Frequently asked questions

01CNC bending

What is CNC sheet metal bending?

It is the process that turns a flat part into a three-dimensional one. The CNC press brake controls the position, depth and sequence of each bend from the program, using industrial tooling.

What does CNC control bring?

Repeatability. The parameters of every bend are fixed in the program, so part number one hundred comes out the same as the first and the run is consistent.

Why does the flat pattern matter so much?

Because the decisive part of bending happens before the machine. Each bend takes up an amount of sheet that depends on the material and the radius; if the flat part is not cut to the right size, the bent part will not reach the dimensions on the drawing, however precise the press brake is.

That is why our engineering office calculates the flat pattern and bend sequence before cutting.

02Drawings and preparation

Do I have to send the part already unfolded?

No. If you send us the finished part in 3D or the drawing with final dimensions, our engineering office calculates the flat pattern. If you already have the flat pattern, we can use that too.

What should the drawing include?

The more complete, the better:

  • Final dimensions of the bent part
  • Material and thickness
  • Bend angles and radii
  • Quantity and whether the order will repeat

If anything is missing, we ask you before manufacturing rather than guessing.

Do you cut and bend in the same plant?

Yes. Bending follows on naturally from sheet metal laser cutting and we do both in the same plant so the two stages are coordinated: the calculated flat pattern is cut and bent without changing supplier.

03Materials, parts and runs

Which materials and thicknesses do you bend?

The materials and thicknesses in the laser cutting table: steel, galvanised steel, stainless steel, aluminium, brass and copper, each with its own thickness range. If the part has an unusual length or thickness, ask us about feasibility with the drawing.

What kind of parts do you make by bending?

  • Housings, covers and enclosures
  • Brackets, angles and custom formed profiles
  • Trays, channels and parts with successive bends
  • Bent parts that are welded afterwards
  • Prototypes to validate dimensions and fit

Do you make prototypes and production runs?

Yes. We work on prototypes, single parts and production runs. A bent prototype is a good way to validate dimensions and fit before committing to a run.

Can you bend a part I have already had cut?

Yes, a bending service on customer-supplied material can be considered. Mention it in your request so we can allow for it in the quote.

04After bending

Can you weld the bent parts?

Yes. Many bent parts are part of a welded assembly, and welding is done in the same plant.

Can nuts or studs be added to the bent part?

Yes. In thin sheet the usual solution is self-clinching fasteners, which anchor into the sheet without welding. The hole is prepared during cutting, so it is worth showing it on the drawing.

05Engineering office and confidentiality

Does my file need redrawing to quote for CNC bending?

No. With DXF, DWG or STEP we work directly on the geometry in your file: the part does not need redrawing and the quote comes back sooner. We work mainly with SolidWorks and AutoCAD, among other CAD and CAM tools.

Are my drawings treated confidentially?

Yes. Drawings are used only to prepare the technical assessment and are not shared with third parties. If you need a signed confidentiality agreement, you can send it to us.

What if I only have a sketch or a technical question?

Send us a dimensioned sketch or tell us what you need. Our engineering office reviews it, asks whatever it needs to and, if necessary, helps you define the part: advice is part of the service, for metalworkers and small workshops too.

06Process, lead times and delivery

What happens after I send my request?

  • Enquiry: you send the drawing, material, thickness, quantity and deadline
  • Review by our engineering office and manufacturing plan
  • Quote and confirmation, with alternatives where there are any
  • Manufacturing within the same plant
  • Inspection, packing and delivery

What lead time does a CNC bending order have?

It depends on the part, the quantity and the other processes involved. In the quote request you can choose a 24/48 h urgent service (with a surcharge), about one week, a flexible deadline or a specific date, and we confirm it with the quote.

Do you have to wait for material before starting?

For many routine orders, no. We keep sheet and tube in permanent stock, so manufacturing can start without waiting for material.

Can you deliver the parts to our factory?

Yes, with our own fleet. We prepare the load and deliver the parts palletised and protected to the agreed point. We usually serve the provinces of Tarragona and Barcelona, and look at other destinations case by case.

07Sectors and experience

Which sectors do you provide CNC bending for?

We manufacture for industrial companies in very different sectors. Some of the most common:

  • Automotive
  • Food industry (stainless steel)
  • Agricultural machinery
  • Construction
  • Structural steelwork
  • Energy
  • Street furniture

Bent sheet housings, brackets, enclosures and profiles are used in practically all of these sectors. If your sector is not listed, tell us about the part and we will confirm whether we can make it.

Why choose Catà Germans for CNC bending?

We are a family company founded in 1958, with more than 65 years in industrial subcontracting of metal parts.

  • Every process under one roof: cutting, forming, machining, welding and finishing
  • Our own engineering office, which reviews the drawing before manufacturing
  • Direct contact with the people who make the part
  • One order and one point of contact, right through to delivery

08Quotes, files and orders

Which file formats do you accept?

We accept PDF, DXF, DWG, STEP/STP, STL, IGS/IGES and also PNG or JPG images. If you do not have a final drawing yet, send us a dimensioned sketch and we will review it all the same.

Do you make one-off parts or only production runs?

We handle one-off parts and prototypes as well as small, medium and large batches and repeat production. You can specify this in the quote request.

How quickly do you reply to an enquiry?

We send the technical response as soon as possible once we have the drawing and the part details.

Do you offer painting, zinc plating or other surface finishes?

You can include them in the order. These finishes are carried out with specialist workshops we work with regularly, but we handle the coordination and the transport: you place a single order and receive the finished part.

Can I combine several processes in one part?

Yes — that is the normal way we work. A part can go through laser cutting, bending, welding and finishing inside the same plant, under a single order and a single point of contact.
