Sonafi was founded in 1951 and initially produced hardware for building (hinges, locks, etc.). In the early 1980s, with the project to install Renault in Portugal, SONAFI was chosen as a partner. It was the first adventure of SONAFI in the automotive market which represents 100% of today's business.
Since 2010 SONAFI has been strongly investing, especially in machining, and is currently in the stage of upgrading the foundry. This upgrade started this year with the acquisition of two Bühler Ecoline S Pro 84.
Today SONAFI is a private company, with Portuguese capital, employing around 250 people. Located in the Porto area, it’s few minutes away from the Francisco Sá Carneiro airport. With a sales volume of around € 35 million, it exports all its production to the automotive sector. Products include EGR valves and coolers, oil pump bodies, filter housings, camshaft bearings, cap bearings, engine supports, etc. for customers like Grupo VW, Valeo, Delphi, Renault or GM. Currently the plant has 24 die casting machines with capacities from 320 up to 1,400 tons of locking force.
