Quality Control

Quality Control from Drawing Review Through Pre-Shipment Inspection

Our workflow covers drawing review, first-piece inspection, in-process sampling, and final inspection, with first-piece, in-process, outgoing, and dimensional records available by order.

Quality Control from Drawing Review Through Pre-Shipment Inspection
Company Quality Process

01

Confirm drawing requirements

02

Approve the first piece

03

Sample by process risk

04

Inspect before shipment

Quality-Control Workflow

Each order starts from a controlled drawing revision and agreed quality requirements, then proceeds through first-piece approval, in-process monitoring, and final release.

01

Drawing and Requirement Review

Confirm drawing revision, material grade, quantity, critical dimensions, tolerances, finishing, cosmetic surfaces, and packaging.

02

First-Piece Inspection

Inspect critical dimensions, hole positions, working surfaces, and appearance before continuing production.

03

In-Process Sampling

Monitor tool wear, dimensional drift, burrs, scratches, and workholding stability during batch production.

04

Final Inspection

Check dimensions, appearance, quantity, identification, and packaging, then prepare agreed inspection or dimensional records.

Inspection Equipment and Tools

Vision, height, roughness, hardness, and general precision tools are selected according to component features.

Dimensions and Hole Positions

Vision measuring machine, height instrument, height gauge

Contours, hole spacing, position, height, and critical working surfaces

General Precision Measurement

Mitutoyo calipers and micrometers

Overall dimensions, thickness, steps, diameters, and fits

Surface and Hardness

Roughness tester and hardness tester

Surface roughness and material hardness condition

Holes and Threads

Pin, plug, thread, go/no-go, and gauge blocks

Hole size, threads, go/no-go results, and fit relationships
