Inspection Is Defined by the Drawing
PinyiGear does not publish a fixed inspection package, because no two drawings ask for the same things. The acceptance criteria are the ones written on the customer’s drawing, and the inspection plan is built from them before the order is released.
What Gets Checked
Typical items, when the drawing calls for them:
- tooth geometry: profile, lead, pitch and runout against the stated class
- bore, shaft and keyway fits, including position and concentricity
- spline and thread dimensions
- hardness and, where specified, case depth
- surface roughness on functional faces
- overall dimensions, width and chamfer
- marking and traceability data
How Results Are Reported
Results are recorded against the drawing’s items, with the measured values and the acceptance limits. A dimensional report is issued when the drawing or the purchase order asks for one. Where a customer wants third-party inspection or a witness during inspection, that is agreed before production starts.
When a Drawing Is Silent
If a drawing lists no inspection items and no accuracy class, we raise it during quotation and agree the criteria in writing. Nothing is assumed silently, because the part will be accepted against whatever was agreed.
Material and Heat Treatment Records
Material certificates are passed on when the purchase order requires them. Heat treatment is verified against the specification on the drawing, and the records that accompany a shipment are the ones the customer asked for.
Rework and Deviation
When a measured value falls outside the drawing, the deviation is reported with the measurement rather than shipped as if it conformed. Disposition — rework, concession or replacement — is agreed with the customer before the parts leave.
