Quality assurance

Luna Quinto S.p.A. has always adopted innovative techniques and methodologies to guarantee the highest quality and reliability.

Nowadays we have decided to go beyond the simple ISO 9001 certification, going towards Lean Manufacturing. The aim is the application of work methodologies and organizational techniques that allow a real "quality", not based on the compilation of sterile forms imposed by who knows which consultant or quality manager, but on a more efficient and effective organizational model.

Lean Manufacturing, however, remains an organizational model that fits perfectly with the spirit of ISO 9001, because it starts from the same assumption and wants to achieve the same goal: continuous improvement.


In addition to being certified by the International Organization for Standardization for Quality Management Systems (ISO 9001:2015), Luna Quinto S.p.A. can boast several certifications for each of its production sectors.
