Cemograf handles all aspects related to raw material procurement according to several methods:
Procurement for Company Inventory – This method is primarily used for materials that are consumed regularly and in quantities that justify storage in the company’s raw material warehouse. All raw materials are procured exclusively from western suppliers who are approved and authorized by the defense industries. Each batch of raw material purchased is always accompanied by quality documents, such as CoC (Certificate of Conformance), which attest to the raw material’s origin and quality.
Procurement Based on Customer Orders – When a customer order requires a special material that is not consumed regularly, or when the required order quantity justifies procurement based on the order, a calculation is made to determine the amount of raw material needed for fulfilling the order. Following this, the raw material is ordered accordingly. Even in this case, the same strict quality protocol applies to accompanying documents and material origin.
Cemograf operates a highly meticulous procurement system that includes frequent reviews of material suppliers and rigorous requirements to meet exceptionally high standards. The broad range of metals handled requires an efficient and precise supplier management system. Every batch of raw materials is received into the company’s warehouse only after passing through the Quality Assurance Department to ensure that the raw materials meet customer requirements and comply with the standards listed in the quality documents. When necessary, material samples are also sent to laboratories for shipment validation testing.
