Quality Control

Quality is promoted and developed internally using Six Sigma and Lean tools and techniques. Various measuring systems (CMM/Laser/Camera ) are employed to suit part design and tolerance’s for example Laser measuring to + or – 5 micron  on split lines. 

All of our Quality Systems are externally validated by the BSI (British Standards Institute to the international standards: ISO 9001 for Quality Management, ISO 14001 for Environmental Management and ISO 22000 Food /Drink Packaging Safety, Hygiene & Security Management.
