Full-Process Closed-Loop Quality Control

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

1. Incoming Inspection - The Source of Quality

• Process: Strict inspection of all incoming raw materials.

• Standard: Verification of material certificates, specification dimensions, surface condition.

• Tools: Spectrometer, Calipers, Micrometers, etc.

• Commitment: Eliminate non-conforming materials from the source, ensuring the reliability of the machining foundation.

2. In-Process Inspection - Prevention is Key

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

• Standard: Strictly following work instructions and inspection standards.

• Tools: On-site Go/No-Go gauges, Calipers, Online measuring equipment.

• Commitment: Real-time monitoring of production status, timely detection and correction of deviations, avoiding batch issues.

3. Final Inspection - Ultimate Check Before Dispatch

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

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

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

• Commitment: Ensuring zero defects in outgoing products.

4. Outgoing Inspection - The Final Guardian
