Plant engineers observed increased out-of-specification surface unconformity defects that were causing 5% of the output to be scrapped. They at first struggled to identify the root cause of the problem. But they were able to use Sight Machine’s variation-analysis tools to find an abnormal variation in evaporation-zone temperature in the oven.
Using Sight Machine, they identified a correlation between evaporation-zone temperature variation and the oven’s airflow-control mechanism. This problem would have been difficult to identify without Sight Machine’s tools and modelled data
The Result: Zero Scrap. Sight Machine enabled them to resolve the problem, eliminating the defects that were causing 5% of the product to be scrapped, reducing the scrap rate to as low as 0%. The project at the plant was so successful that the company has decided to expand the use of Sight Machine’s productivity platform to its global network of plants.
Toros Tarim is the leading manufacturer of fertilizer for Turkey and neighboring regions. This large scale process requires a huge industrial chemical complex with each step in the production pathway (sulfur acid to phosphoric acid to ammonium diphospate for example) being dependent upon the former. Downtimes are extremely costly, with potential to impact all areas, including the on-site co-generated electricity whose surplus also bolsters the Turkish electrical grid. Toros approached Sight Machine as part of their digital transformation and lean journey with the clear expectation to start at building a contextualized data platform of all their data, facilitating an holistic view of their process network, before moving to data visibility and automated dashboarding of reports and key performance indicators (KPIs).
The next part of the journey is now underway as Sight machine and Toros partner to use their data platform to explore advanced analytics such as predictive and AI, process optimization (including for sustainability and emissions management), and maximizing plant reliability / minimizing asset downtime. This project was implemented entirely remotely during the COVID-19 pandemic and was possible because of the unique way Sight Machine is able to rapidly ingest and use automated tool sets to transform and contextualize tens of thousands of data fields in parallel.
Carbon Revolution is as innovative and disruptive as a technology can be. They fabricate carbon fibre wheels (rims) that are both lighter and stronger than current aluminum constructions. While these concepts started with sales to niche manufacturers such as Ferrari, they are now becoming commonplace options on more mainstream manufacturers. As production ramps up and concomitantly unit cost drops these will undoubtedly become the new normal over time, just as aluminum rims did to steel decades before. Carbon Revolution is using Sight Machine to provide an end-to-end view of its fabrication process in real time. For this fast paced company, instant access to data is paramount as it rapidly grows. Track and trace of a wheel to understand weaknesses in quality and fabrication techniques needs expedited root cause analysis.
Sight Machine provides end-to-end visibility by automating all of the data collection, cleaning, aligning, and joining, even for out of order records. This frees up engineers to be refining their processes for growth and not using their valuable time hand-prepping data for hypothesis testing. With all of their data at their finger tips Carbon Revolution aims to retain their agility and speed as they scale and be at the forefront of using their digital data.
