Meeting and exceeding expectations of our customers

Impol has a wide range of tools for manufacturing discs at its disposal. Careful maintenance helps our products meet the wishes and needs of our customers, and we constantly develop new solutions. Discs and stamped shapes with specific properties can be subject to further treatment by the following methods: deep drawing, spinning and subsequently enamelling or teflonising. Technological knowledge enables us to advise semi-finished goods users which chemical composition and properties should be selected so as to meet and exceed their expectations.



Discs are manufactured from 1000, 4000, 5000, 6000 and 8000 series alloys. Soft, half-hard, and hard tempers that can also be combined with deep drawing ability are also available. Their mechanical properties comply with international standards and can, if need be, be fully customised to the customer’s wishes.



Intended uses

deep drawing manufacturing of household containers
double bottoms in household containers
the manufacturing of pressure vessels
the manufacturing of lighting fittings
the manufacturing of satellite antennas

Technological manufacturing process

Discs are manufactured from rolling slabs subject to hot rolling to the prescribed thickness. Cooling thereof is followed by cold rolling supported by additional operations such as in-process annealing and trimming. Cold rolling until the final thickness is followed by stamping and final annealing. All these operations combined provide for the desired final disc shape, prescribed dimensions and quality.
