Quality Inspection

Inspection evidence you can review before shipment.

Define critical dimensions, material records, sampling, visual criteria, functional checks, and export documentation before production starts.

Control plan

Inspection should follow the part’s functional risk.

Not every dimension needs the same method or frequency. Critical features should be identified early and matched to capable equipment and sampling.

IN

Incoming verification

Material identity, certificates, heat numbers, purchased components, and external process records.

IP

In-process inspection

Datums, machining stock, key dimensions, hardness, setup approval, and process checkpoints.

FA

Final dimensional inspection

Critical dimensions, geometric controls, threads, roughness, and drawing-defined acceptance.

VI

Visual & workmanship review

Casting defects, burrs, sharp edges, finish appearance, cleanliness, marking, and handling damage.

FN

Functional checks

Assembly fit, gauge checks, pressure, movement, torque, leak, or other agreed application tests.

PK

Packing verification

Quantity, identification, corrosion protection, separators, labels, crate condition, and document match.

Technical evidence before production
Inspection planning

Match the method to the tolerance and feature geometry.

A sound plan considers measurement access, datum simulation, equipment capability, uncertainty, sampling, and how the customer will review the result.

Calipers, micrometers, height gauges, and bore gauges
Thread gauges and functional fixtures
CMM or optical measurement for complex geometry
Hardness, coating thickness, and roughness measurement
Visual standards and approved reference samples
Dimensional reports, certificates, photos, and traceability
Practical workflow

Quality gates from material receipt to export packing.

1

Plan the controls

Identify critical features, methods, frequency, records, and responsibilities.

2

Verify during production

Measure early enough to prevent repeated nonconforming output.

3

Complete final release

Confirm drawing, workmanship, finish, marking, quantity, and documentation.

4

Link records to shipment

Keep reports, lot identity, labels, and packing information traceable.

Deliverables & controls

A documentation package aligned with the purchase order.

Document the technical basis so purchasing, production, inspection, and shipment use the same requirements.

Dimensional inspection report

Critical or full-layout results according to the agreed sampling and report format.

Material and process certificates

Chemistry, mechanical properties, heat treatment, coating, or outsourced process evidence as required.

Nonconformance and approval records

Document deviations, disposition, rework, and customer authorization before shipment.

Packing and shipment evidence

Photos, counts, labels, crate information, and final document checks for export orders.

Frequently asked questions

Questions buyers ask before release.

Use these answers as a starting point. Final acceptance criteria should be tied to the drawing, purchase order, and approved technical record.

Can you provide full dimensional reports?+
Yes, when the report scope, ballooned drawing, sampling, format, and first-article requirements are defined before quotation.
Do you support third-party inspection?+
Third-party witnessing or inspection can be coordinated when the scope, timing, access, and cost are included in the order requirements.
How are critical dimensions identified?+
They can be marked on the drawing, listed in the RFQ, or agreed during review based on fit, safety, sealing, load, and assembly risk.
Can inspection records be linked to each batch?+
Yes. Traceability level should be specified, including heat, lot, serial, pallet, or shipment-level identification as appropriate.
