Impol has a tradition of several decades in the production and processing of aluminium, especially in the field of extruded and drawn rods, bars, tubes and profiles.
Impol’s own casting house with a capacity of 60,000 tons of ingots, its electric and gas furnaces and a continuous homogenising furnace enable to produce rods, bars, tubes and profiles from over 40 alloys.
The foundry supplies cast homogenised billets of all standard qualities or a quality to customer’s demand.
After homogenization, billets are 100% ultrasonic controlled in order to ensure the quality of our products even for the most demanding customers (forging, automotive and aircraft industry, etc.)
Fields of use of rods, bars, tubes and profiles
- the automotive and aircraft industries
- machine building
- transport
- interior design
- electrical industry
- civil engineering
Production process
The process of the production of rods, bars and tubes includes operations which enable the production of high quality heat-treated materials: homogenisation and turning of billets, heating of billets and extrusion in the most state-of-the-art press, cold and hot working and straightening and cutting to length.
Pressing takes place in three presses which ensure a high quality of extrusion. The procedures of indirect and direct extrusion are used.
Cold working (drawing) of products takes place on standard drawing machines and continuous drawing lines (drawing, straightening, cutting to length). In accordance with international standards, Impol produces extruded and drawn rods and tubes in all standard dimensions. Hardened alloys, which are not so easily worked or even difficult to work, predominate. Special attention is given to stress-free states of materials, to free-cutting alloys and to rods for forging.
After the production process, the products can be 100% ultrasonic controlled on customer’s demand.
Production programme
Impol’s production programme includes:
- round, hexagonal, square and flat rods and bars
- full sections
- pipes and tubes: seamless
- oval-shaped pipes / tubes - ferrules
- shapes to customer demand
