In-Process Control: Hirschmann’s Series-Wide Quality Control

Hirschmann Automotive relies on a multifaceted process that demands the highest precision to always produce high-quality components. Advanced product quality planning (APQP) and in-process control (IPC) are fundamental to this process.

After checking customer-specific documents and successfully performing a feasibility study, the APQP elements in the project phase are handled. As soon as the project phase is complete, the products go into series production, which is when IPC begins.

IPC – Process-Verified Quality
During IPC, production is cyclically monitored and documented, allowing specific features of individual products to be checked with precision and, if necessary, facilitating intervention at an early stage. IPC is standardized at all Hirschmann Automotive production plants. This allows us to satisfy the high demands of the automotive industry and our customers’ needs.

Automated Analyses in Line with Standards
Graphic progression analyses, trend observations, and statistical evaluations of process capability are automated during IPC and meet the standards of the German Association of the Automotive Industry (VDA). Manual progression analyses or graphic observations, which might contain incorrect measured values or data entry errors, are a thing of the past.

Intervention thanks to System Warnings
All IPC staff are warned via automatic traffic light controls as soon as values drift beyond defined action limits, allowing for effective intervention into the process. This makes it possible to prevent disruptive noises and other product deficiencies. The software is based on our current SAP master data, which ensures traceability to measuring equipment and production machines that were used.
