05. Series production launch

The combination of stable processes with high process capability and consequent monitoring of the production process leads to a low error rate. We account for the process capability by means of the SPC method and by determination of the Cpk and Ppk values. This monitoring is not limited to the short-term values during the series production start-up. It also serves as evidence for the productions long term capability.

We are committed to a zero defect strategy and follow the objective of keeping down the ppm rate as low as possible. When requirements cannot be achieved reliably by process design, we employ a 100% inspection. Machine sorting is accomplished by opto-electronical control. We conduct this special sorting as in-house service and also subcontract to external facilities. Certain features are either only verifiable through machine sorting using disproportional efforts or not feasible at all. In such cases we resort to a 100% manual and visual control.

  • Spot check or 100% inspection
  • Finished parts inspection
  • Series production documentation
  • Identification and traceability
  • Continuous monitoring and improvement

Finished part inspection

The spot checking of finished parts is performed in our well-equipped test center (acceptance sampling inspection acc. to ISO 2859). Product monitoring and documentation during series production is executed, evaluated and recorded by our quality assurance team. Upon customer request for exceptionally application-critical components we commit to additional monitoring by external supervision.

Traceability imageThumbnailAlt Traceability

Identification and traceability from the compound batch through to the finished part is a high priority. Our barcode system enables us to trace every step from the order entry to the final delivery on all related documents. Using this system in our software we can transparently link each individual component to all of the production stages it has passed through.
