Our speciality is sawing slugs from pressed and drawn rods, allowing us to offer customers a variety of slugs diameters. With this program, we ensure the production of sawn slugs from all types of aluminum alloys, in various diameters and thicknesses. The diameters of the saw-cut discs range from 10.00 mm to 100.00 mm. We manufacture discs with thicknesses from 11.00 mm up to 200.00 mm or more.
We collaborate with customers on various projects, jointly developing both shapes and special aluminum alloys.
Advantage of our sawn slugs – both the shape and the alloy can be developed in collaboration with the customer:
| ALLOYS AND TREATMENTS | |
| Alloys | Aluminium alloys of any type |
| Heat treatment | O-soft annealed |
| T4-solution annealing, T6-aging, H18-hard | |
| Surface treatment | vibrating, shot blasting, no surface finishing |
| DIMENSIONS AND THICKNESSES | |
| Diameter [mm] | 15.00 – 120.00 |
| Thickness/length [mm] | 11.00 – 280.00 (or more) |
Manufacturing process
Bars for sawing into slugs are also acquired within the Impol group. We apply pressed and drawn bars. The latter, in particular, enable us to achieve extremely narrow tolerance ranges to meet the most stringent quality and technical standards.
High productivie and high quality saws are used for precision cutting into different thicknesses. After sawing, slugs are annealed according to different annealing programmes, as specified by the customer. This is followed by surface finishing by means of shot blasting or vibrating and, finally, by packaging and storing.
