Blank

Niche production of blanks enables us extraordinary flexibility, technological perfection, and innovation. The fact that aluminium is the future material is our consideration by blank,s produced using hot-drop forging. Impol supplies its products to many prestigious motorcycle and car producers. Our blanks are also applied in the assembly of sports requisites and the military industry. Impol is distinguished by its wide range of blanks provided to the market manufactured from 2xxx to 7xxx alloys. We have also mastered complex product treatment procedures: thermal treatment, grinding, stone vibration, and leaching. The hot-drop forging process The hot drop forging process starts by cutting aluminium rods to proper lengths and is followed by heating blanks to a specific temperature to loosen the crystal structure and increase the deformability of the material. This procedure is followed by the hot drop forging process, whereby the forging temperature depends on the aluminium alloy used. When forging is completed, forgings are trimmed and heat treated. After that, further work may be carried out on the forged products, such as leaching, vibratory finishing, sandblasting, or machining. Production takes place on six forging lines. The force ranges from 0.45 to 1.3 MN. During the forging process, aluminium blanks are heated by gas reheating furnaces. The average weight of forgings varies between 0.05 to 5 kg. A wide range of aluminium alloys is used for forging – from 2000 to 7075. Tools are produced in cooperation with toolmakers that grant short delivery periods and good quality, thus increasing our flexibility, constituting a prerequisite for market competitiveness.
