Inspection and testing

From incoming wire to finished parts, quality checks at every stage.

  1. Wire inspection

    Inspect incoming wire before production, controlling quality from the raw-material stage.

  2. Salt spray testing

    Assess corrosion resistance of finished-part surfaces and protective layers through salt spray testing.

  3. Metallographic examination

    Examine material microstructure and its condition.

  4. Tensile testing

    Check the response of finished parts under tensile loading.

  5. Torque testing

    Check how the product responds to torsional loading through torque testing.

Applicable tests and acceptance criteria depend on product specifications and customer requirements.
