Stage-By-Stage Inspection

Four checkpoints, applied to every production order.

Checkpoint · Documentation

Control of Documents & Records

  • System files controlled and managed for the operation of the management system
  • Drawing and specification versions kept consistent with the product on the floor
  • Records maintained as objective evidence that product meets requirements
ISO 9001 documentation control
Checkpoint · Incoming Material

Inspection of Raw Materials

  • Supplier management applied at the point of incoming goods
  • Appearance checking on all incoming material lots
  • Characteristics inspection against the purchasing specification
Supplier & incoming-goods control
Checkpoint · In-Process

Process Control & Dielectric Verification

  • Process inspection performed at each manufacturing step
  • Final inspection confirms each unit's testing complies with the applicable standard
  • Insulation withstand levels (LI / AC ratings) confirmed against GB1094 / IEC60076 before release
GB1094.3-2003 dielectric reference
Checkpoint · Equipment

Calibration of Test Equipment

  • Configuration, calibration, and maintenance of inspection/measuring/test equipment is controlled
  • Calibration cycle managed to keep accuracy consistent with the required measure capacity
  • Equipment use logged to keep results reliable and standard-compliant
Calibrated measurement chain
Process

Treatment of Unqualified Products

  • Clear operating procedure of analysis, processing, and retrospect for deficient purchase
  • Defined handling path for non-conforming product on the line
  • Customer complaints tracked through the same retrospective procedure
Process

Quality Improvement

  • Regular internal management review meetings on quality results
  • Adverse trends identified and corrected in a timely manner
  • Tracking and confirmation built into the review cycle, not a one-off audit
Published Service Promise Matrix

Seven commitments. No fine print.
