Detection of process deviations with SPC methods
Respond to process changes in a timely manner and identify systematic influences in manufacturing support before rejects occur
Statistical Process Control (SPC) offers comprehensive manufacturing support with digital connection to processes and manufacturing stations as well as automatic testing machines and measuring equipment. Use analyses with Link into capacity and production planning. Use standardized evaluation methods and control charts to prove your normative requirements. The knowledge gained from your process data flows into continuous improvement management. For example, use the 5S method to evaluate workplace organization. Extensive analysis options show you trends and potential for improvement.

Implementation of process improvement at the customer
The inspection data recording was largely integrated across all machines via an automatic log import. The majority of the characteristics flow into the CAQ database in automatically running orders. Finally, the inspectors check the orders as required and confirm them in a final characteristic by visual inspection. Automatic warning systems provide rule-based information about relevant deviations in production. In addition, a central online monitoring portal provides browser-based and continuous information about the current status of the key figures and the failure rate.
