Quality Reports & Documentation

FAI Reports

First Article Inspection reports for every new part

Dimensional Inspection Reports

Comprehensive measurement data for critical features

Material Certificates

Material composition and grade verification

NDA Compliance

Standard confidentiality process for all submitted designs

Surface & Hardness Measurements

Surface roughness and hardness test results

Machining Tolerances

Critical tolerance control: ±0.05mm
Tighter tolerance (e.g. ±0.01mm) can be evaluated based on your drawing requirements.

Category	Typical Tolerance	Notes
General Machining	±0.1mm	Standard for non-critical features
Precision Machining	±0.05mm	Our standard critical tolerance
Tighter Tolerance	±0.01mm	Can be evaluated per drawing
Large-Format Parts	Evaluated per project	Evaluated based on part dimensions

Certifications & Compliance

Quality documentation is available for every project. ISO and other certifications documentation is available on request — contact us for current status.

We do not display certification logos until certificates are formally obtained. Our quality commitment is demonstrated through our inspection process, documentation and measurement capabilities.

Confidentiality & NDA

We take intellectual property protection seriously. Our standard confidentiality process covers all submitted designs:

NDA available for signing before reviewing your files
All CAD files and drawings stored securely with access controls
Customer information is never shared with third parties
Files are removed from our systems upon request after project completion

Quality Control FAQs

What inspection process do you follow?

Every part goes through our 5-step inspection process: incoming material inspection, first article inspection (FAI), in-process inspection, final inspection and outgoing inspection.

Do you provide inspection reports?

Yes. We provide FAI reports, dimensional inspection reports, material certificates, surface roughness and hardness measurements. NDA compliance and RoHS/REACH supplier documentation available upon request.

What tolerances can you guarantee?

Critical tolerance control down to ±0.05mm. Tighter tolerance (e.g. ±0.01mm) can be evaluated based on your drawing requirements. We do not commit to tolerances beyond our verified capability.

Are you ISO certified?

Quality documentation is available for every project. ISO documentation is available on request — contact us for current certification status.

Can you sign an NDA?

Yes. We have a standard NDA process. NDA can be signed before we review your files, and our standard confidentiality process covers all submitted designs.

Do you provide material certificates?

Yes. Material certificates are provided with every shipment, verifying material composition and grade.

What measuring equipment do you have?

Surface roughness tester, hardness tester, precision measuring tools (calipers, micrometers, gauges). CMM (Coordinate Measuring Machine).

How do you handle non-conforming parts?

We follow a documented non-conformance process. Contact us for details on our corrective actions and containment procedures.
