MAHLE is an international development partner and supplier to the automotive industry. At its South African operations it wanted to modernise an ageing line-side process that prints product labels based on the results of quality-assurance checks run by automated PLC jigs.
We replaced a decentralised system with a modern .NET solution, rolled out one production line at a time so the old system could be retired gradually. Configuration, audit and reporting all moved to one central place, and end users can now create and apply new label designs without needing a developer. We added device-driver-level printing so MAHLE can use any Windows-compatible label printer, and a software interpreter between the test jig and the system to standardise the messages it receives. The solution supports multiple languages and non-Latin character sets, which matters for an international business, and every part can be traced back to a date and time, operator, test jig, production line and batch.
MAHLE now manages its line-side quality control centrally, with end-user configuration, auditing and reporting built in. The modernised system cut technical debt and removed a dependency on external capability and proprietary code, and historic labels can be reprinted whenever they are needed.
