A lot of people connect Industry 4.0 with digitalization, big data, and smart manufacturing but not as much with PMI (positive material identification) testing. However, in each industrial age we do not lose the key components of the previous revolution, but rather we use new ideas and technology and theory to boost the productivity in our existing manufacturing process. The need for quality control gains even more importance with the introduction of a smart factory and smart production.
When a process is totally automated and integrated into the internet of things (IoT), we are only able to ensure that the right product is manufactured through quality control by showing the elemental composition of incoming and outgoing materials using the most modern and latest spectrometer technology.
