Innovation in forming processes

Flexibility in batch sizes

Speedy delivery of samples

Speedy logistics during mass-production phase

High quality standards

Analytical engineering

We are with you throughout the entire process

Our highly qualified team, which undergoes training on a constant basis, applies its forming know-how to come up with the best solution for each case

We carry out an in-depth study of the part

We examine its geometry, its technical limitations, its technical requirements and functions in order to draw up an analysis of feasibility and consultancy work to find a pipe transformation solution.

Prototype, sample and pre-production phases

We carry out prototype, sample and pre-production phases for the purpose of obtaining empirical and analytical results, to enable us to control exogenous factors and also internal factors in the pipe transformation process. These analyses are carried out alongside engineering work for our customers, and they are essential for components with major technical requirements.

Implementation of the production process

We reach the mass-production phase, during which we control the process parameters and apply the quality controls necessary to obtain parts matching our customers’ technical requirements. We use a number of systems to guarantee the sealing on the pipes we form. We work with regular production programmes or to order, adapting our work to the production and logistics requirements of our customers.

Large adaptable facilities

The flexibility of our facilities enables us to undertake both small and large volumes of production, adapting to changes in our customers’ plans on an extremely competitive basis.

Our location in Debagoiena has enabled us to build relationships of proximity, leading us to standardise and apply good practices with other customers, making us a European role model in metal pipe bending solutions. As Chief Executive Officer, I home in on initiative and a proactive attitude to undertaking projects and driving them forward, keeping ahead of any difficulties that may arise, and this is only possible thanks to all those who are a part of Nemesio Zubia.

Julia Abadía, CEO

My personal and professional background has always been connected to Nemesio Zubia. Origins, enthusiasm and sacrifice are values I have experienced at home since I was a child. I joined Nemesio Zubia after completing my studies in mechanical engineering, and over the last 25 years I have undertaken many challenges and headed up many projects, the most recent of which is my current position as Head of the Industrial Division. I have been with the company during these years of growth, and I have seen good times and other times which were more difficult and beset with uncertainty; but we have always come through, with much awareness of our customers’ needs, striving to provide them with value through our products. This has been and still is our raison d’être.

Iñaki Zubia, Head of Industrial Division

The ISO 9001:2015 quality certificate issued by Bureau Veritas bears out the high standards of our work. NEMESIO ZUBIA, continuous quality.
