Quick Answer
How Does FSD Ensure Manufacturing Quality?
Quality is controlled throughout the manufacturing process, not only checked after production. Quality control is planned from engineering review through material traceability, process control, inspection, documentation and delivery verification.

Quality Control Workflow
Manufacturing Quality Control Workflow
Each stage reduces risk before parts move to the next manufacturing or delivery step.
Engineering Review
01Check drawing requirements, critical dimensions, tolerance requirements and manufacturing feasibility.
- Drawing Requirements
- Critical Dimensions
- Tolerance Requirements
- Manufacturing Feasibility
- Quality Evidence: Drawing Review Record
Material Verification
02Confirm material grade, supplier documentation and certification requirements before production.
- Material Grade
- Supplier Documentation
- Certification Requirements
- Quality Evidence: Material Documentation
In-Process Quality Control
03Use first article checks and production monitoring to reduce process variation.

Inspection
04Verify dimensions with suitable inspection methods based on drawing requirements.
- CMM
- Vision Measurement
- Calipers
- Micrometers
- Quality Evidence: Measurement Data
Surface Inspection
05Review functional and cosmetic surface requirements before shipment.
- Surface Finish
- Color
- Coating
- Cosmetic Requirements

Material Traceability
Material Traceability & Compliance
Traceability connects material documentation, production records and final quality evidence. Documentation examples may include material certificates, MTC records, RoHS compliance and REACH compliance when required by the project.
Raw Material
Material grade and incoming requirements confirmed.
Supplier Certificate
Supplier documentation reviewed when required.
Material Verification
Material identity and project requirement alignment checked.
Production Record
Process route and batch information documented.
Final Documentation
Records prepared based on agreed quality scope.
Material Certificate SampleMTC ExampleBatch Record ExampleFinal DocumentationRoHS / REACH when required

| Metal Stamping | Fit Risk | Burr / Springback | Dimensional Check | Tooling Adjustment | Inspection Result |
Inspection Standards
Inspection Standards & Sampling Plans
Inspection level should match part criticality, production volume and customer requirements. The inspection scope is defined by drawing risk and agreed project requirements rather than unsupported certification claims.
Critical Features
100% inspection can be used when dimensions directly affect fit, assembly or function.
Production Parts
Sampling inspection can be used for production batches when sampling is appropriate.
Custom Projects
Customer-defined inspection protocols can be agreed before production based on project requirements.
Inspection Examples
Real Inspection Examples
Inspection requirements depend on product, material, process and quality focus.

FAQ
Quality Control Guide FAQ
What quality inspections does FSD provide?
FSD supports dimensional inspection, CMM inspection, visual inspection, surface finish review, material verification and final documentation for OEM manufacturing projects.
Does FSD provide CMM reports?
Yes. CMM reports can be provided for precision components when dimensional verification is required, especially for critical mounting features and tight tolerance parts. See the CNC Machining Guide ->
Can FSD support FAI?
FSD can support first article inspection for production validation when the project requires dimensional confirmation before batch production.
How does FSD control manufacturing quality?
FSD controls quality through engineering review, material verification, process control, in-process checks, dimensional inspection, surface review and final documentation.
What quality documents are available?
Available documents may include inspection reports, dimensional measurement data, FAI reports, material certificates and surface inspection records.
How are materials verified?
Materials can be verified through material grade confirmation, supplier documentation, material certificates, production records and final documentation.
Can FSD inspect surface finishes?
Yes. Surface finishes can be reviewed for appearance, color, coating, roughness and cosmetic requirements based on drawing notes and customer acceptance criteria. See the Surface Finishing Guide ->
How does FSD ensure batch consistency?
Batch consistency is supported through engineering review, process control, first article checks, production sampling, critical dimension inspection and final verification. For early review, use Engineering RFQ Review ->
