Our Quality Certification Cornerstones

Authoritative certifications are the solid foundation of our quality management system and the source of your confidence.

• ISO 9001:2015 Quality Management System Certification

• Signifies that our quality management has reached international standards, achieving systematic and standardized operations.

• IATF 16949:2016 Automotive Industry Quality Management System Certification

• This certification represents one of the highest standards in quality management, demonstrating our ability to produce zero-defect, high-reliability products that fully meet the requirements of the most demanding industries such as medical and automotive.

  
  

Full-Process Quality Closed-Loop Control

Quality is both manufactured and inspected. Our control runs through every step of the product lifecycle.

1. Incoming Material Inspection - The Source of Quality

• Process: Strict inspection of all incoming raw materials.

• Standards: Verification of material certificates, specifications and dimensions, and surface conditions.

• Tools: Spectrometer, calipers, micrometers, etc.

• Commitment: Eliminate unqualified materials at the source to ensure the reliability of processing fundamentals.

2. In-Process Inspection - Preventing Problems Before They Occur

• Process: First Article Inspection (FAI) and In-Process Quality Control (IPQC) during production.

• Standards: Strictly in accordance with work instructions and inspection standards.

• Tools: On-site go/no-go gauges, calipers, online measuring equipment.

• Commitment: Real-time monitoring of production status to promptly detect and correct deviations, avoiding batch problems.

3. Final Inspection - The Ultimate Check Before Delivery

• Process: 100% or AQL sampling Final Quality Control (FQC) of finished products.

• Standards: Fully compliant with customer drawings and technical requirements.

• Tools: Coordinate Measuring Machine (CMM), 2D Optical Comparator, Surface Roughness Tester, etc.

• Commitment: Ensure zero defects in delivered products.

4. Outgoing Inspection - The Final Guard

• Process: Final confirmation (Outgoing Quality Control - OQC) of product status, quantity, and packaging before shipment.

• Commitment: Ensure products you receive are intact and with accurate quantity.
