Our Group

SigmaSince its creation in 2005, SIGMA, which specialises in the manufacture of injection molds, has joined forces with ATTEM (72) and then strengthened its position with the acquisition of CORTINOVIS (39) in 2007, one of SIGMA's main strengths being its Chinese partnerships with which the CEO has been developing several types of services for more than 20 years. During all these years, the procedures put in place allow the working methods to be the same in China as in our French workshops. Sigma imposes its rigor, and our Group now relies on its 3 French sites in various strategic locations. In China, in Shenzhen, we offer more and more solutions for our international customers.
