Industry: our vocation

The company is centred around our design office and technical support

Our desire to work with industrial operators, to help them maximise their performance and responsiveness, dates back to 1994.

For the last fifty years, a major industrial turning point has forced manufacturers to refocus on their core business to improve their competitiveness and flexibility. As a result, they need to make use of external consulting firms, which have both the capacity to help them improve their clients’ technologies, processes and costs, whilst also optimising market constraints in terms of flexibility, competitiveness and, above all, updating their skills.

The Engineering and Technical Consulting Group The SEIMAF Group was born from an awareness of this situation and, to maximise interaction with its clients, its business model is based on a global “à la carte” way of working.

As a Project Engineer, I need to provide technical expertise in order to ensure that our clients are satisfied
