Optional Customer-Specific Reports

Depending on customer or industry requirements, we can also include:

• PPAP (Production Part Approval Process) documents for automotive clients.
  
• CQC (China Quality Certification) for specific domestic projects.
  
• Third-party verification reports (e.g., TÜV, SGS, or Intertek).
  
• Thermal performance simulations and reliability test data.
  

This modular reporting structure ensures that each customer receives exactly the level of detail required for their internal or regulatory documentation.

Example of Documentation Flow

1. Material Stage: Receive mill certificate → Verify alloy → Record lot number.
   
2. In-Process Control: Record process parameters → Conduct sample checks → Archive data.
   
3. Final Inspection: Complete dimensional and surface test → Sign off QA approval.
   
4. Shipping Stage: Compile all reports into a document package → Release shipment only after QA validation.
   

This process guarantees full traceability for every component shipped from our facility.

Do we issue COC, CQC, or material inspection reports?

Certification is the bridge between production and customer trust. Without it, even the best parts cannot pass quality audits or approvals.

Yes, we issue Certificates of Conformity (CoC), China Quality Certification (CQC), and detailed material inspection reports for all products as required.

These documents ensure that every aluminum heat sink we ship has verifiable records confirming its material, mechanical, and process integrity.

Overview of Our Common Certifications

Certificate Type	Description	Standard Reference
CoC (Certificate of Conformity)	Confirms compliance with drawings, specifications, and standards	ISO 9001 / IATF 16949
CQC (China Quality Certification)	Required for specific domestic and export products	GB/T and CCC regulations
Material Inspection Report	Chemical and mechanical data of aluminum alloys	ASTM B209 / JIS H4000 / EN 573
Surface Treatment Report	Anodizing thickness, hardness, and sealing quality	MIL-A-8625 / ISO 7599
Performance Validation Report	Thermal and pressure test data	IEC / MIL-STD-810 standards

Each certificate or report carries the responsible engineer’s signature and a unique trace code linking it to the production batch.

Sample Content: Material Inspection Report (6061-T6 Alloy)

Property	Unit	Specification	Test Result	Standard
Tensile Strength	MPa	≥ 260	271	ASTM E8
Yield Strength	MPa	≥ 240	247	ASTM E8
Elongation	%	≥ 8	10	ASTM E8
Density	g/cm³	2.70	2.70	ASTM B209
Hardness	HV	85–100	92	ASTM E384

All test results are traceable through our Manufacturing Execution System (MES), which records time, date, machine ID, and operator responsible.

Certification Validation

Every certificate includes:

• Company logo and quality system certification number.
  
• Product identification (drawing number, revision, and serial).
  
• Testing standards and methods used.
  
• Approval signatures by Quality Manager and QA Engineer.
  

Customers can validate the authenticity of the certificate through our document verification portal or via email confirmation from our quality department.

Are test results archived and available for audit?

Quality assurance doesn’t end after delivery — it extends through record retention and transparency.

Yes, all test results, inspection data, and certifications are digitally archived and available for internal or customer audits at any time.

Our digital record management system ensures long-term storage and traceability of every production and test record.

Record Retention Policy

Data Type	Retention Period	Access Level
Material Certificates	10 years	QA, Customer (upon request)
Dimensional Reports	5 years	QA, Customer (upon request)
Surface Treatment Data	10 years	QA, Environmental Dept.
Process Logs & Test Results	10 years	QA, Production
Calibration & Equipment Records	5 years	QA, Maintenance

All records are backed up on secure servers with access control, ensuring data security and confidentiality.

Audit Readiness

We welcome customer audits, third-party inspections, or quality system reviews at any time. During audits, customers can access:

• Historical test results of specific batches.
  
• Equipment calibration certificates.
  
• Operator training records.
  
• Corrective and preventive action (CAPA) reports.
  

Each record is organized according to ISO 9001 and IATF 16949 traceability requirements.

Auditors or customers can review test logs either in digital format or as printed archives on-site.

Data Traceability Example

Each product batch is assigned a unique Lot Number. This code links:

• Raw material certificate → Process log → Inspection report → Shipping record.
  With this system, any part in the field can be traced back to its full production and test history.

This level of documentation traceability ensures confidence in long-term product reliability and compliance.

Is customer approval needed before report submission?

Communication and transparency are key elements of customer satisfaction. Every client has different reporting requirements depending on their industry — aerospace, automotive, or electronics.

Yes, customer approval is obtained before final report submission to ensure that the report format, scope, and content meet their exact requirements.

Before production begins, we align documentation requirements with the customer through a formal approval process.

Standard Approval Workflow

1. Document Template Submission:
   We send sample report templates (CoC, inspection report, material test form) for review.

2. Customer Review and Feedback:
   The customer reviews data format, test scope, and report layout.

3. Confirmation and Approval:
   The customer confirms preferred reporting parameters and required standards (e.g., ASTM, JIS, EN).

4. Final Report Generation:
   After production, reports are compiled according to the approved template.

5. Electronic and Physical Submission:
   Final documents are sent in PDF format for review before shipment release.

Advantages of the Approval System

• Eliminates errors in report structure and content.
  
• Ensures alignment with client audit requirements.
  
• Simplifies system certification for customers (e.g., UL, AS9100, ISO).
  
• Improves communication efficiency and mutual understanding.

Example: Automotive Client Workflow

An automotive customer required PPAP documentation with every order. Before starting production, we confirmed the content list — including DFMEA, PFMEA, control plan, material report, and CoC — then aligned testing standards to IATF 16949.

Once reports were generated, they were submitted electronically for approval. Only after receiving written confirmation did we attach final documents to the shipment package.

This approach ensures zero discrepancies during customer audits and full satisfaction in documentation accuracy.

Conclusion

We deliver complete test reports and certifications with every order, including CoC, CQC, material inspection, and performance validation reports. All data is archived for 10 years and available for audit. Customers review and approve reporting formats before final submission, ensuring full traceability, accuracy, and compliance across every project.
