Identify mounting, sealing and connection dimensions from the approved reference.
Fitment dimensions
Dimensional Inspection
Dimensional inspection focuses on the features that determine fit, sealing, alignment or connection with neighboring parts.
Inspection basis
Measure the dimensions that control installation
Overall length alone rarely proves fitment. Mounting holes, shoulders, sealing faces, connection angles and relative positions are selected from the approved drawing or sample and checked with suitable equipment.
- Critical dimensions are defined before the batch check begins.
- Measuring method and reference points are kept consistent.
- Results outside the agreed range are isolated for review.

Inspection steps
Measure consistently
Use the defined datum, equipment and method for sampled or required checks.
Review deviations
Compare results with the accepted range and investigate outliers before release.
FAQ
Inspection questions
Can an OE number replace dimensional checking?
No. The OE reference supports identification; critical dimensions still confirm the supplied part.
Are all dimensions checked on every unit?
The plan depends on the part, risk and agreed inspection level; critical features receive priority.
Can buyer drawings be used as the reference?
Yes, after the drawing revision and critical requirements are confirmed by both sides.

01
Incoming Material Inspection
Incoming inspection checks whether the received material or component matches the approved purchase reference before it enters production or packing.
View details02Performance Testing
Performance checks must match the actual function of the part; a generic test cannot represent every braking, sealing, electrical or rotating component.
View details03Pre-Shipment Inspection
Pre-shipment inspection confirms that the prepared goods and export pack correspond to the released order, not just that individual parts look acceptable.
