Packaging & storage

METEXIM LTD foundry (site № 1) implements a stock up, processing, sorting out and loading of ferrous and non-ferrous metal scraps. Further in the process of re-melting the aluminum & aluminum alloy scraps in the appropriate furnaces the foundry produces aluminum ingots.

The following types of ingots are mainly produced:

The working process begins at the stock up site, where the received product undergo radiation testing. The product is being accepted & weighted on the electronic scales. Aluminum and aluminum alloy scraps are being sorted by the type & the chemical contents, then carried out a mechanical cleaning and separation from iron, plastic and other materials.

The sorting of the product is one of the most important stages of raw material processing. Certain types of the product are being briquetted. The recycled product is being transported to the casting plant. There are installed two furnaces with the appropriate equipment & loading, unloading lines.

The first furnace is designed for the casting and cleaning. The production volume is about 150-200 tons per month. The first furnace produces iron-free aluminum melts, which are subsequently transferred to the second furnace for secondary melting.

The second furnace is of the reflective type from HIDROER MAK SAN plant.

Analyses

The production volume is about 200-250 tons of finished products per month. The sorted aluminum is being automatically loaded into the furnace. The loading and melting process is being performed gradually, accompanied by the preliminary analyses. During casting process there are being used appropriate ligatures, flues & other necessary additives & components to obtain aluminum alloy that meets certain standards.

The plant has a quality control laboratory that uses a NITON X-ray spectrometer and a stationary multi-base optical emission analyzer Was Lab Foundry Master.

Unloading is carried out through a conveyor line. The metal is being poured into molds and extracted after cooling. Afterwards it is being sorted, marked by type, weight, analysis, after which the ingots are being transported to the packaging site, they are being bounded, weighed and transported to the loading site.

The shipment of finished products is being carried out by cars or containers through the customs terminal.
