Quality approach
Component quality begins before the first manufacturing step
Inspection characteristics, evidence and approval criteria are considered during technical project development, creating end-to-end quality planning from raw material to installation-ready delivery.
01Prevention
Identify and control risks early.
02Transparency
Document measurements and approvals.
03Series stability
Continuously monitor characteristics.
04Improvement
Feed learning back into processes.
Inspection and approval
Evidence matched to component, process and application
The scope of inspection is derived from the drawing, specification, material, safety relevance and series volume. Results are consolidated in clear project documentation.
Inspection and quality methods
A coordinated system rather than isolated inspections
Type and scope are defined for each project. The decisive factor is reliable evidence of function and series capability.
Material testing
Chemical analysis, certificates and mechanical properties.
Dimensional inspection
Record and assess drawing characteristics traceably.
Initial samples
Measurements, evidence and process data for approval.
Process capability
Monitor series characteristics and process parameters.
Special testing
Non-destructive, mechanical and functional testing.
Traceability
Clearly assign batch, inspection and delivery data.
