Quality Control Map

From Drawing Review to Outgoing Quality Check

Each project follows a controlled quality path. Drawings, materials, critical dimensions, surface requirements and final shipment conditions are reviewed at different stages to help reduce manufacturing and delivery risks.
01

Drawing Review

Drawings, CAD files, tolerances, threads, surface finish notes and critical features are reviewed before production planning.

02

Material Verification

Material grade, certificates and incoming material conditions can be checked according to project requirements.

03

First Article Inspection

Key dimensions and drawing requirements can be verified before batch production continues.

04

In-Process Control

Operators and QC staff check dimensions, machining status and process stability during production.

05

Final Inspection

Dimensions, appearance, threads, surface finish and required inspection records are reviewed before release.

06

Outgoing Quality Check

Parts, labels, packaging status and shipment documents are checked before delivery to customers.

Buyer Note: For projects with strict tolerance, regulated material, cosmetic surface or batch consistency requirements, please include your inspection standards when sending RFQs.

Process Quality Control

Quality Assurance – End-to-End Process Control

Design Optimization:Early-stage support with DFM guidance to optimise design and reduce manufacturing costs. DFM Analysis:Anticipate manufacturing risks, identifies potential issues, and provides solutions to ensure manufacturability. Precision Machining:3-, 4-, and 5-axis milling, turning, and grinding for high-precision manufacturing of complex geometries. Surface Treatment:PVD coating, anodising, sandblasting, and polishing to enhance both appearance and performance. Full-Dimension Inspection :CMM inspection, spectrometer analysis, and full-process traceability to ensure compliance with specifications.

Inspection Capability Matrix

Match Critical Features with the Right Inspection Methods

Different quality risks require different inspection methods. This matrix shows how dimensional, threaded, surface, cosmetic and documentation-related requirements can be supported during production and final review.
检测项目三坐标 CMM卡尺 / 千分尺量规粗糙度仪外观检查报告支持
Inspection ItemPosition, flatness, hole spacing, profiles
Threads & HolesInternal threads, external threads, pins, bores
Surface RoughnessRa / Rz requirements and machined surfaces
Cosmetic SurfacesAnodized, plated, polished or visible parts
Material VerificationMaterial grade, certificate, batch records
Final Packaging CheckLabels, quantity, protection and shipment readiness
说明: Note: Inspection methods depend on part geometry, tolerance requirements, material, surface finish and buyer-specified acceptance standards. Please provide 2D drawings with inspection notes whenever possible.

Critical Features Inspection

Focus on Features That Affect Fit, Function and Appearance

Precision parts often fail because of a few critical features rather than the whole part. We pay attention to tolerance zones, threaded areas, surface requirements and cosmetic surfaces that may affect assembly, function or customer acceptance.
01

Tight Tolerances

Critical dimensions, hole positions, flatness, perpendicularity and profile requirements can be reviewed according to drawings and inspection notes.

02

Threaded Features

Internal threads, external threads, tapped holes, inserts and mating features can be checked with gauges and visual review before shipment.

03

Surface Finish

Machined surfaces, sealing faces, contact surfaces and roughness requirements can be checked when Ra or finish requirements are specified.

04

Cosmetic Surfaces

Anodized, plated, polished, painted and visible parts can be visually checked to reduce scratches, dents, stains or finish defects.

Inspection Equipment

Measurement Tools for Dimensional, Thread and Surface Checks

Inspection equipment is selected according to part geometry, tolerance requirements, drawing notes and buyer-specific standards. For precision features, critical dimensions and surface requirements, additional inspection support can be arranged before shipment.

01

Coordinate Measuring Machine

Used for critical dimensions, hole positions, profiles, flatness and complex geometry verification when required by drawings or inspection plans.

02

Height Gauge

Supports height, step, depth and reference surface measurements during in-process and final inspection.

03

Micrometers & Calipers

Used for common dimensional checks, thickness, outside diameter, inside diameter and general feature verification.

04

Thread Gauges

Used to verify internal threads, external threads, tapped holes and mating thread features before shipment.

05

Pin Gauges

Support hole size, bore, slot and fit-related inspections for precision parts and assembly features.

06

Surface Roughness Tester

Used when Ra, Rz or other surface roughness requirements are specified for machined faces or contact surfaces.

07

Visual Inspection Tools

Used for appearance review, surface defects, scratches, dents, contamination and finish consistency checks.

Quality Documents

Inspection Records That Support Traceability and Approval

Quality documents can help buyers verify dimensions, materials, inspection results and shipment readiness. Reports and records can be prepared according to drawing requirements, approval standards and project documentation needs.
01

First Article Inspection Report

Used to verify key dimensions and drawing requirements before batch production continues.

02

CMM Inspection Report

Supports critical dimensions, hole positions, profiles and complex geometry verification when required.

03

Material Certificate

Material certificates can support grade verification, traceability and engineering documentation.

04

Final Inspection Report

Summarizes final inspection results before parts are released for packing and shipment.

05

Surface Finish Record

Can support surface roughness, appearance review or finish-related inspection requirements.

06

Packing Inspection Record

Confirms labels, quantity, protection method and shipment readiness before delivery.

Documentation Note: Please confirm required reports before production starts. Some documents may depend on material availability, inspection scope, tolerance requirements and buyer-specific approval standards.

Quality FAQ

Common Questions About Inspection and Quality Control

These answers help buyers understand how inspection reports, CMM measurement, material certificates, first article inspection and quality requirements can be coordinated before production and shipment.
Do you provide inspection reports for CNC machined parts?

Yes. Inspection reports can be provided based on project requirements, including dimensional inspection records, CMM reports, photos or final inspection summaries.

Can you provide CMM inspection reports?

Yes. CMM inspection can be arranged for precision parts, critical dimensions and customer-specified features when required for verification or approval.

Do you perform first article inspection?

Yes. First article inspection can be used before batch production to confirm key dimensions, tolerances, materials, surface finish and drawing requirements.

How do you control quality during production?

We use drawing review, in-process checks, operator inspection, dimensional verification and final inspection to help reduce variation before parts move to surface treatment or shipment.

Can you provide material certificates?

Yes. Material certificates can be provided when required for traceability, engineering records, regulated projects or buyer documentation.

How should I specify quality requirements in my RFQ?

Please include 2D drawings, CAD files, tolerance requirements, critical dimensions, material grade, surface finish, inspection report needs and any special acceptance standards.
