Our suppliers use induction furnaces, modern casting equipment and machining tools in their production process. The machinery and technologies ensure excellent mechanical properties of the castings. The products we offer undergo quality control to confirm that the items we sell are free from defects.
Our suppliers test the mechanical properties of their products and analyze their chemical composition using emission spectrometry. They also conduct penetration, ultrasonic tests, radiographic examinations, metallographic microscopic examination and issues certificates of conformity with EN 10204-2.2, 2.3, 3.1B.
During centrifugal casting process, metal is poured into a rapidly rotating metal mold. The metal is pressed against the walls of the mold with centrifugal force. The pressure created ensures close contact between the metal and the mold. Gases and intrusion are transferred towards the center of rotation, to the inner part of the casting, which is removed by subsequent treatment. The casting gradually solidifies away from the wall in the direction of the axis of rotation. The remaining molten metal is pushed into the foundry cavities, which improves the homogeneity of the casting.
