All the production process stages involve intermediate checks that guarantee process reliability. The data gathered is processed by specific software that provides statistical analysis of the process.

All the measurements taken are carried out using suitable control tools, from the most sophisticated like the 3D controlling machine to the simplest like digital callipers, micrometers, boremeters, comparators and fixed callipers.

Every check is recorded on specific documents that accompany production right through to despatch and are then filed for ten years. .
