Own foundry constitutes the heart of the Impol Group
State-of-the-art equipment and continuous modernisation and expansion of our foundry casting capacities follow quality demands of the aircraft and automotive industries. Our rich metallurgical knowledge updated throughout the company's entire existence has helped us develop several alloys that are semi-continuously cast in billets and rolling slabs of various dimensions and continuously in wide cast coils. Our foundry casting programme currently includes more than 170 various chemical compositions. The number thereof is on the rise on an annual basis. Impol has a foundry in two locations: in Slovenia, where mainly billets and cast coils are cast, and in Serbia, where mainly rolling slabs are cast. Both programmes can be, however, cast in both foundries. Lines are modern and computerised, monitored and equipped with archive storage of process parameters.
With greater power and capacities
The capacity of our two foundries amounts to 210,000 tonnes of castings, out of which 110,000 tonnes are manufactured in Slovenia and 100,000 tonnes in Serbia.
The modernisation of muffle furnaces has resulted in a greater opportunity to apply a larger share of secondary and organically more contaminated waste as well as in lower pollution and amount of flue gases released into the environment. Thus alloys can, in addition to pure industrial waste, also include a larger share of collector waste aluminium. The quality of alloys has been improved despite the increased share of collector aluminium.
Quality comes first
After the foundry casting and homogenisation processes on billets have been completed, they are also 100 % controlled by means of an ultrasonic device that facilitates ultrasonic control of billets in compliance with the AMS MIL-STD-2154, Class B and A, and ASTM B594, Class B and A, standards.
During the years to come, the company will mainly increase the wide coil foundry casting capacity and modernise as well as increase its homogenisation capacities.
