2025 has been an intense year. More than 250 propellers repaired! Each one with its own story, diagnosis, and technical process: welding, geometric correction, dynamic balancing, polishing and final check. Over 250 different projects, but a single goal: providing real and precise

En Metalnox no trabajamos sobre suposiciones, trabajamos sobre datos. Con el escaneado 3D digitalizamos la geometría completa de la hélice y convertimos cada milímetro en datos medibles, lo que nos permite detectar desviaciones, optimizar perfiles y garantizar que vuelva a

At Metalnox we don’t work on assumptions, we work with data. With 3D scanning we digitise the full geometry of the propeller and turn every millimetre into measurable data, allowing us to detect deviations, optimise blade profiles and ensure it performs exactly as originally

The difference between silent navigation and constant vibration can come down to almost imperceptible millimetric misalignments. At Metalnox, we don’t leave that margin to chance. We verify every shaft using high-precision instrumentation to ensure perfect flatness, exact fitting

En nuestras instalaciones, muchas de las hélices que recibimos no solo requieren experiencia técnica… también requieren capacidad. Hablamos de piezas de gran tamaño y peso, que deben moverse con total seguridad entre las distintas estaciones de trabajo: escaneado 3D, soldadura,

At our facilities, many of the propellers we receive require not only technical expertise… they also require capacity. We’re talking about large, heavy components that must be moved safely between different workstations: 3D scanning, welding, machining, balancing and polishing.

Si necesitas ajustar o instalar tu sistema de propulsión, nuestro equipo está preparado para hacerlo con la precisión que exige el mar. En este caso, hemos realizado el acoplamiento de una línea de propulsión con hélices hidráulicas, midiendo con precisión el nivel de ajuste de

If you need to align or install your propulsion system, our team is ready to do it with the precision the sea demands. In this case, we carried out the alignment of a propulsion shaft line with hydraulic propellers, accurately measuring the propeller adjustment level to ensure

No siempre es necesario desmontar una hélice para saber qué le ocurre. En este caso nos desplazamos donde haga falta para realizar el escaneado 3D directamente en el barco. Con los datos obtenidos, analizamos la geometría completa desde nuestras instalaciones y podemos determinar

It’s not always necessary to remove a propeller to know what’s wrong with it. In this case, we travel wherever needed to carry out a 3D scan directly on the vessel. Using the data obtained, we analyze the full geometry from our facilities and can determine precisely what

Dos hélices gemelas y un mismo problema: un siniestro que, entre otras muchas cosas, ha afectado a la geometría original de la hélice. En este caso, hemos reconstruido una de ellas y la hemos escaneado en 3D para obtener sus medidas exactas y conocer con precisión cómo debe ser

Two twin propellers and the same problem: an incident that, among many other things, has affected the propeller’s original geometry. In this case, we rebuilt one of them and carried out a 3D scan to obtain its exact measurements and determine precisely what its original geometry

The countdown to the Palma International Boat Show has begun. From April 29th to May 2nd, Moll Vell in Palma will bring together a large part of the nautical sector in a setting defined by innovation, knowledge and connection. At Metalnox we will be supporting partners and

When a shaft shows damage, corrosion or material loss, it is not always necessary to replace it. At Metalnox we apply welding (cladding) to rebuild the surface, controlling the pre-weld preparation and heat input to ensure a strong bond. Applied engineering to extend the service

It’s not just the propellers that determine the performance of a propulsion line. Struts are a key component in ensuring the proper alignment and stability of the shaft. In this project, we found the struts in very poor condition after a collision involving the vessel, which

Does your propeller “sing”? The singing phenomenon creates a high-pitched noise while sailing, caused by vibrations at the trailing edge of the blades as they rotate. At Metalnox, we apply a precision technique known as “anti-singing”, which consists of slightly modifying the

En Metalnox, cada proyecto comienza con un diseño en 3D… y termina cumpliendo exactamente lo que el cliente necesita. Para esta barandilla, hemos llevado a cabo un proceso completo de diseño, fabricación y ensamblaje a medida, trabajando el metal con precisión para garantizar

At Metalnox, every project begins with a 3D design… and ends by delivering exactly what the client needs. For this railing, we carried out a complete process of custom design, fabrication, and assembly, working the metal with precision to ensure structural strength, durability

Precision on and off the water. Today we set aside nautical propulsion to work on this excavator, which was showing wear on the shaft where its various attachments are fitted. This type of damage often leads to play, vibrations and a greater risk of failure in the assembly. With

In just one month Metalnox will be heading to Vigo! From the 19th to 21st of May we will be taking part in one of the leading international trade fairs in the shipbuilding industry, Navalia, and this year we’ll have our own stand. Take the opportunity and ask us for tickets to
