The product traceability for each single batch is ensured and equipped with a certificate of chemical analysis, and, on request, with X-Ray video control, tensile strength testing, penetrating fluids test and metallographic report.
The laboratory is equipped with a “150 kV GILARDONI” X-ray machine with a rotating board for the radioscopic control of castings, a “SPECTRO” spectrometer for the chemical analysis of alloys, a hardometer, penetrating fluids and tensile strength testing equipments, together with a metallographic laboratory and a laboratory to control molding sands.
The castings can be delivered:
» sandblasted with stainless steel
» with heat treatment (temper, solubility, artificial ageing techniques)
» mechanically machined
» vibratory finishing
» powder painting coated
» with anodic oxidation
» with electrophoresis treatment
