Continuous Measurements and Statistical Process Control
During the manufacturing process steps, the operator certifies the quality of the product with repeated measurements according to the Statistical Process Control (SPC) method. This allows an evaluation of the deviation trend of process parameters from specification ranges and prevents the manufacture of defective parts through the early intervention of the process operator. By this way, the process capability can be defined and followed up. In case of subcontracting, the evidence of quality conformity has to be given by the subcontractor. An additional quality check by sampling is made with the incoming inspection, in order to assure that the quality level of the subcontractor is the same of Viemme Srl.
