FACTORY

Our factory cast aluminium billets for production according to international standards and the chemical composition specifications requested by our long-lasting customers. The quality of Aluminij billets is guaranteed and enhanced by auxiliary equipment such as spectrum analyzer, online hydrogen degassing system, hydrogen detectors, ultrasonic billet testers and homogenization furnaces.

Materials are tested in our laboratory before they enter the production process, thus ensuring exclusive use of flawless materials. Our production and testing processes are optimized on an ongoing basis and Aluminij’s laboratories provide an in depth chemical spectrum analysis of alloy composition spark test for each billet produced, to ensure maximum accuracy.

Aluminij’s 6XXX series billets are produced by semi-continuous vertical casting using Wagstaff technology – Air Slip, and are intended to be further extruded into profiles, bars and tubes of different shapes and applications.

Wagstaff billet casting systems are the foundation of our high-quality billet production. The options are virtually endless, with diameters available from 152 to 254 mm and strand counts from 36 to 78 billets per drop. Hundreds of alloy compositions have been proven on Wagstaff casting systems and the limits are continually stretched with new common and aerospace alloy development taking place in Wagstaff’s production-scale R&D cast house laboratory.

The Wagstaff Air Slip Air Casting Technology produces the highest quality billets, known for their smooth surface finish, small shell zone and uniform – grain structure – the world standard for billet quality.

Through the use of new technology and investment in employees, Aluminij has constantly improved its product quality. This includes a comprehensive IT system upgrade, quality control processes and cutting-edge environmental protection technologies. Workplace safety continues to be central to everything we do, and by adopting new procedures and comprehensive awareness programs, we have developed an outstanding safety record that exemplifies modern production methodology.

By the end of June 2002, the first comprehensive modernization project for Aluminij Factory had been completed at a cost of 250 million Euros, which brought in new technologies and introduced production upgrades that increased output, efficiency and quality. With its impressive technological solutions this state of art equipment significantly reduces noise levels and dust emissions in the workspace and the wider environment.

In 2008, the Green Anode Plant was modernized and a new vacuum vibrocompactor, a patent from Outotec, was installed. The same year the replacement of the old Fume Treatment Plant by new one, based on the adsorption of the anode furnace exhaust gases on the alumina surface was done by Innovatherm Prof. Dr. Leisenberg GmbH & Co. KG.

A crucial improvement that was introduced to Aluminij's production process is the use of ultrasonic testing, which is an indispensable component of quality inspection for aluminum extrusion billet and forging stock. Testing of cast billets for center cracks and cavities has been standard practice in aluminum cast houses for many years, however, usually with portable hand-held UT equipment, which means only random checks are made. For the production of highly stressed components, particularly for the aircraft and automotive industries, reliable examination of all billet material used is mandatory. Ultrasonic testing should be performed directly after casting to avoid costly further processing of faulty material.

Our factory uses primary aluminum and aluminum scrap to cast aluminum billets according to strict international standards and the chemical composition specifications requested by our long-lasting customers.

At Aluminij we are using an ultrasonic testing, which is an indispensable component of quality inspection for aluminum extrusion billet and forging stock. Depending on the application, fully automatic linear or helical stations are available to be integrated in the production flow or installed as stand-alone installations, as required.

For quality control of billet surface Hertwich has developed a billet surface inspection using ultra sound technology for every billet in order to reliably detect even smallest surface defects on aluminium billets caused by the casting process and if any detected it is removed automatically.

Aluminij’s primary responsibility is to protect the health and safety of all employees, including business partners and visitors. Therefore, security systems and security devices have been installed throughout the Aluminij facility to monitor and oversee all safety protocols. Education and training programs are provided on a daily basis for employees and contractors to maintain safety awareness at all times.

All operations and activities in Aluminij are designed with protection and safety measures for people and the environment at their core.

Work areas are constantly assessed to ensure compliance with health and safety at work recommendations and regulations. Aluminij is one of rare companies in this part of Europe, which systematically performs humanization of work.

The company invested tens of millions of euro in the environment protection programs and became the first certificate holder of this kind in the Herzegovina-Neretva Canton and one of four companies in Bosnia and Herzegovina, which hold this certification.
