Quality management is used for this. During production, it is therefore checked whether the gradual processing of the material does not show undesirable fluctuations in the values of the monitored properties and the production takes place according to the technological regulation. If the deviations from the prescribed condition are significant, the semi-finished product is returned for repair (if applicable) or disposal (if necessary) and production intervention is performed to achieve normal condition. In the end, everything is guaranteed by the output control.
