Tapping, countersinking and secondary operations

It lets the part take a screw directly, without a nut. It is the usual way to prepare removable joints in metal parts.

It lets the screw head sit flush with the surface instead of standing proud. It matters when another part has to sit on top or when the surface is visible.

• Tapping for joints without nuts
• Countersinking for flush screws
• Riveting
• Preparing fixing points before assembly
• Operations ahead of painting or dispatch

Because these operations decide whether the part can be assembled straight away or whether someone will have to rework it first. Doing them in the same plant avoids that extra step and the risk of damaging a finished part.

It depends on the finish planned. Our engineering office plans the order of operations so that neither the thread nor the surface treatment is compromised.

Show the thread sizes you need on the drawing and we will confirm them when we reply to your request.

Yes. The operations are programmed together with the rest of the part, for single parts and runs alike.

CNC machining

Thin sheet often lacks the thickness for a reliable thread, so the usual answer is a self-clinching fastener. In thicker material direct tapping is normally enough. We assess it from your drawing.

Self-clinching fasteners

Yes, that is the usual flow: a cut or punched part can go on to bending, tapping or fastener insertion within the same plant.

CNC punching

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.

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

Any part that is screwed together at assembly needs them: housings, brackets, frames and equipment in all of these sectors. 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.
