The ISO/TS 16949:2002 quality standard used for many years now in crankshaft manufacture assures the high standard of quality. Our inspection equipment is able to meet the highest quality requirements.
The following four inspection steps are standard practice in the ALFING automotive crankshaft production:
- First part inspection:
This is carried out after each new operation set up. The workpiece is measured in an clean measuring room. All dimensions measured are documented and used where appropriate for subsequent operations.
- Inspection by the operator:
The operator carrying out a particular operation checks the quality and dimensional accuracy of the results he has produced for each crankshaft.
- Random tests:
Based on the frequency specified in the quality control plan, random samples are removed by inspectors from the on-going production and checked in the clean measuring room. The measurement results for the samples tested are documented and evaluated as appropriate.
- Washing, final inspection and packaging:
This step is carried out in the fully air-conditioned, dust-free (overpressure) QA room. Measuring and electronic documentation of the specified dimensions/features. Visual inspection and marking of the crankshaft ready for installation.
