The metal packaging machine can extrude various metal scraps (such as steel shavings, scrap steel, scrap aluminum, scrap copper, scrap stainless steel, and scrap automotive waste) into rectangular, octagonal, cylindrical, and other qualified furnace materials, which can not only reduce transportation and smelting costs, but also improve furnace feeding speed. This series of packaging machines is mainly suitable for steel mills, recycling and processing industries, as well as non ferrous and ferrous metal smelting industries.
