Tradition. Knowledge. Flexibility.
The flexibility and capacity of our production are evidences by very short delivery times of our products. The quality of the manufactured slugs also results from long-standing experience. Our tradition is reflected in the manufacture of all types of stamped and sawn slugs from pure aluminium and aluminium alloys. Impol offers slugs of various dimensions and shapes which are applied in the manufacture of tubes, cans and technical parts in the automotive and other industries. We listen to our customers’ needs even when supplying smaller quantities of quality products.
Own foundry, stamping and sawing
The slugs manufacturing process begins by casting a narrow strip manufactured in our own foundry. The foundry manufactures narrow cast strip of various widths and from various alloys (EN AW 1070, EN AW 1050, EN AW 3102 and EN AW 3207). The narrow strip is then hot- and cold-rolled to various thickness and coiled. Cold coils then constitute input raw material for stamping slugs on stamping machines. Five stamping machines are used (120–160 tonnes). Investments in more powerful stamping machines that would provide for stamping a thicker slugs programme are foreseen in the future. After the stamping process, slugs are soft annealed and surface treated. Surface treatment can be carried out by means of sandblasting or vibrating, depending on the customers’ wishes. Surface treatment is followed by packing and storing as well as product dispatching to customers.
Slugs are also stamped from EN AW 6082 and EN AW 3003 alloys, but the manufacturing process takes place in hot-rolled plates manufactured from EN AW-6082 rolling slabs.
Sawn slugs from extruded rods or bars and tubes are also manufactured in the manufacturing process, providing sawn slugs of various diameters and lengths. Sawn slugs are manufactured from a wide range of aluminium alloys (EN AW-1xxx, EN AW-3xxx, EN AW-5xxx, EN AW-6xxx in EN AW-7xxx).
