Raw Material Control

Chemical Analysis

For the raw material to be used in the production, samples are taken per casting number basis and analyzed for chemical properties to identify if requirements specified by Ozkan norms, national/international standards, or customer specific needs are met during the quality control entrance phase. Only raw material confirmed by the Quality Assurance Department are used for production.

Surface Control

Visual controls of the raw material to be used in production are carried out during the quality control entrance phase. Any cracks, burr, notches, oscillation marks, and corner defects that could negatively affect the product surface quality are identified beforehand and sorted out with the surface control to achieve the perfect surface quality.

Dimensional Control

Dimensional controls of the raw material to be used in production are carried out during the quality control entrance phase. This control includes section measurement control, diagonal/deviance control, and length control stages. All dimensional controls are performed with measurement tools with assured calibration.

Etching Control

For the raw material to be used in production, samples are taken per casting number basis and are analyzed for any defects of the internal structure using macrographic examination.
