Interview to José Ramón Ramírez, technical director-commercial of Dyfa
Devoted to the design and the manufacture of toolings for sectors of high technological requests, like the aeronautical sector component manufacturing sector component manufacturing, the nautics and the automotive sector, the company
What kind of parts manufactured for the aeronautical sector?
From useful molding in steel, nickel and invar, drawn steel and aluminum tools, and useful for routing and drilling in steel, aluminum and composite materials (manual and CNC), until shells of etching, shells of fiber, useful rubber and oil press, forming tooling and welding pipe, mould thermoforming, control gauges, models, master and prototypeuseful for Assembly and final Assembly, as well as machining, Beveling, drilling parts both metal and composed by CNC.
What would you highlight?
The latter: machining, Beveling, drilling metal and composed of CNC parts. In addition, we are the only company authorized in Spain by Airbus for the design and manufacture of tooling for moulding in nickel.
Work for the aeronautical sector and the automotive industry requires high quality standards, how is it certified?
Through international certifications. Dyfa is certified in design and manufacturing of Airbus tools for machining, Beveling, drilling of composite material parts. We also have the certifications of ISO9001 and ISO9100.
Do projects have participated and which aeronautical signatures?
Collaborative projects developed by Dyfa in the aeronautical sector have been diverse and with firms such as Airbus, Aernnova and Aciturri to supply elements of the stabilizer, horizontal and vertical of the A350 XWB, A320, A330, of the new model of Bombardier, the helicopter NH 90, Embraer 145, 170-190, KV-390 and Falcon.
What would require large firms to companies that subcontract? It is complex to be part of these projects?
It is not easy. Essentially required companies a high qualification and who, moreover, have with means of production and extensive technical knowledge.
If I had to advise a company of machining that would like to enter this market, I would say that the penetration in the aeronautical sector is complicated. It requires considerable investments both in the field of engineering and the manufacturing, therefore times are long.
Which is the most complex piece that have realizar and what half needed for his manufacture?
Without a doubt, one of the pieces that have a technological challenge have been the exterior panels of the vertical stabilizer of the A350 XWB model Shell.
Also made components and primary parts for sectors such as aeronautics, AutoMotion and naval. Are these markets associated part in your billing?
Machining parts of series for the aeronautical sector is the most representative area. This represents 55% of the total turnover of Dyfa. In addition, the design and manufacture of tooling for the aeronautical sector represents 30% of the turnover, while designing and manufacturing in the automotive sector is 15%. On the other hand, and unlike other companies of similar activity, we do not export directly.
Projects that I would stress for the next three years?
There are several projects that we have three years, such as those related to the A350 XWB, A330, NH90, Embraer 170-190 and KC390 models.
What are the main challenges in the field of design and manufacture of tooling for the aeronautical sector?
We believe that one of the major technological challenges in the design and manufacturing of tools in this segment is the improvement of tools for the machining of composite materials.
Is the Spanish aeronautical sector a good time? Still room for growth?
Dyfa understands that the implementation of new investment depends on obtaining aeronautical orders currently in negotiation and whose catchment will lead the workshop capacity increase to the high level of occupation of its industrial capacity.
And now to conclude, what kind of products and services offer for the automotive sector?
For this industry which, as I mentioned, represents 15% of our turnover, we design and manufacture models of control parts and prototype models.
The human and technological equipment
Dyfa has a staff of 34 people dedicated to the design and manufacture of aeronautical and machining tooling of aeronautical parts in composite materials. Therefore has a milling Jobs Gantry 5 axes (7.000 x 3 200 x 2 000) with CNC Fidia of 16,000 rpm, KXP Gantry DMC100 5 axes (10.000 x 4 000 x 1 500) with Fagor CNC of 20,000 rpm and a KXP Gantry FGB510 of 5-axis (6.000 x 3 500 x 1.700) with Fagor CNC of 20,000 rpm.
In the field of control, featuring a Laser Tracker beacon with Metrologic software and a three-dimensional machine 2 arms (6.000 x 3 000 x 1, 800) and Metrologic software. In CAD/CAM, the company makes use of two units Catia V.5, Catia V.4 unit and a Tebis.
