The dimensional check is an essential procedure for obtaining very precise measurements for the production of complex components. In particular, the automotive, aeronautical and medical sectors require the utmost attention to detail and elements. The dimensional checks carried out by FPM allow it to ascertain any thickness changes or deformations. The three-dimensional control machine allows a precise verification of the die-castings and plastic details and, at the same time, a comparison with the 3D mathematical model.
