  • Three-stage inspections

    Material quality management is assured by a rigorous three-stage inspection system, after goods receipt, before processing, and before shipping.

  • Three-stage inspections

    As with the three-stage inspections from parent to finished material to ensure the right dimensions, three-stage inspections are also undertaken for markings before cutting, for dimensions after cutting, and before shipping and packaging.

  • Visual inspection before cutting

    Precise visual inspections are always undertaken for scratches or dents before cutting, including a light reflection check.
