Quality Input
Drawing + Material + Critical Dimensions
Confirm machining and inspection requirements before production
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.
Company Quality Process
01
Confirm drawing requirements
02
Approve the first piece
03
Sample by process risk
04
Inspect before shipment
Process Control
First Piece + Sampling + Final Inspection
Set inspection priorities from volume, geometry, and critical dimensions
Quality Records
First Piece / Process / Outgoing / Dimensions
Reporting scope is agreed with the order and customer requirements
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.
Three Quality Gates
Pre-production, in-process, and pre-shipment gates separately control drawing interpretation, batch stability, and delivery condition.
01
Before Production
Confirm the machining direction
- Drawing revision
- Material and quantity
- Critical dimensions
- Finishing and packaging
02
During Production
Control batch variation
- First-piece result
- Sampling records
- Tool condition
- Burrs and appearance
03
Before Shipment
Confirm delivery condition
- Final dimensions
- Appearance
- Quantity and labels
- Packaging protection
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
Set Inspection Priorities from Drawing Risk
Critical, important, and general characteristics receive different attention. Actual inspection frequency depends on geometry, volume, and customer requirements.
A
Critical Characteristics
Dimensions affecting function, assembly, or explicitly identified by the customer receive first-piece and process focus.
B
Important Characteristics
Dimensions affecting location, appearance, or downstream operations are sampled by volume and process risk.
C
General Items
General shape, quantity, identification, and appearance are confirmed during final inspection.
Available Quality Documents
Quality documents are provided according to order size, drawing requirements, and customer agreement; formats are confirmed at quotation or order placement.
01
