Incoming Inspection for Stator Cores Material

Incoming inspection verifies raw materials and components before production to ensure they meet specified grades, dimensions, surface quality, and customer requirements.

Ensuring Material Quality from the Beginning

We verify material grade, thickness, surface condition, magnetic properties, and certificates before production to ensure reliable raw materials and consistent quality throughout the entire manufacturing process.

  • Material grade verification according to customer requirements

  • Thickness measurement and tolerance control

  • Surface quality inspection

  • Coating condition evaluation

  • Flatness and dimensional accuracy checks

Raw Material Inspection

Silicon Steel Sheet Inspection

Incoming silicon steel sheets are carefully inspected to ensure:

High-quality electrical steel ensures excellent magnetic performance and stable motor efficiency.

  • Sheet thickness

  • Length and width dimensions

  • Roundness and flatness

  • Burr condition

  • Tolerance compliance

Dimensional Inspection

All incoming materials are measured using precision inspection equipment to verify:

Material Certificate Verification

  • Material certificates (MTC)

  • Steel grade and specification

  • Mechanical and magnetic performance data

  • Batch traceability information

Before production, we verify supplier documentation including:

Supplier Quality Management

  • Supplier evaluation

  • Batch inspection records

  • Material traceability management

  • Continuous quality improvement

We work closely with qualified suppliers and maintain strict incoming quality standards through:

Quality Gate Before Production

Only materials that pass incoming inspection are released for production, ensuring every stator core is manufactured with consistent performance and reliability.
