CNC sheet metal punching

It is a process that works by cutting and forming with tooling: a tool strikes the sheet and makes the hole or shape in a single stroke. CNC punch presses work with interchangeable tooling and run the program prepared by our engineering office.

• Perforations and rows of holes
• Tool-cut shapes and cut-outs
• Embossing and raised features
• Formed countersinks
• Ventilation louvres and other local forming

Catà Germans introduced one of the first CNC punch presses in the area in the late 1980s, and punching is still one of the core capabilities of the workshop.

As a guide: the laser is better for complex contours, varied parts and thicker material; punching is more efficient when there are many identical, repeated operations or the material needs to be formed.

Sheet metal laser cutting

Form the material rather than only removing it: embossing, raised features, formed countersinks and ventilation louvres are operations specific to punching.

When we receive the drawing, our engineering office assesses which process suits your part best, based on geometry, number of operations and quantity, and explains it with the quote.

• Perforated sheet and ventilation grilles
• Parts with many repeated perforations
• Embossing and formed features on sheet
• Holes for self-clinching fasteners
• Runs where the same pattern repeats part after part

Punching is especially efficient for production runs and repetitive parts: when the same pattern repeats many times, each operation is done in a single stroke.

Sheet in the materials and thicknesses of the laser cutting table. For special formats or thicknesses, ask us about feasibility with the drawing.

Yes, that is the usual workflow. A punched part can go on to bending, tapping or fastener insertion within the same plant.

Tapping and countersinking

It depends on the use. If the part is handled by hand, has to sit against another part or will be coated, vibratory finishing removes burrs and rounds the edges of whole batches with consistent results.

Vibratory deburring

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.

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.

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.

Engineering office

• 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

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.

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

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.

Transport and delivery

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

Perforated sheet, grilles and parts with many holes are common in construction, energy, street furniture and industrial equipment. If your sector is not listed, tell us about the part and we will confirm whether we can make it.

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

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.

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.

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

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.

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.
