Improving aluminium sheet production through expert vibration engineering

Why vibration matters in aluminium sheet production

Aluminium sheet production includes casting, rolling, levelling and finishing processes where vibration directly affects surface quality, process stability and equipment condition.

Vibration within this process can introduce surface irregularities such as roll marks, thickness variation or repetitive markings.

This is important because aluminium is widely used in products such as beverage cans, automotive and aerospace components, where small defects tolerated during production can become visible after painting, printing, or forming, leading to poor finishes and increased scrap.

Beyond quality, unwanted vibration can shorten the life of machine elements like rolls, bearings, couplings, and structural supports. Over time, this leads to increased maintenance and reduced productivity across the line.

Common quality defects in aluminium sheet

Chatter and gauge variation

Certain vibration behaviours, including 3ʳᵈ octave and 5ᵗʰ octave modes, can cause periodic strip marking or variations in thickness.

Roll marks / print patterns

Repetitive markings along the strip length often come from poor roll surface condition or vibration between the rolls and the strip.

Marks from trapped material

Small particles or bits of material caught between the strip and the rolls can leave recurring marks on the surface.

Uneven lubrication marks

Irregular distribution of rolling oil can leave lines or residue on the strip, leading to visible streaks after processing.

How Vibremo supports aluminium producers

Vibremo supports aluminium sheet producers by investigating vibration issues in rolling mills, roll grinders, levellers and finishing lines.

Our work combines on-site measurements, mechanical knowledge and process understanding to determine how vibration develops during production and how it affects strip quality.

Our recommendations are practical and focused on improving surface quality and operational efficiency, including improvements to roll condition, inspection of rotating components, structural reinforcements, or adjustments to operational parameters to optimise process.

We also offer follow-up measurements to confirm the effect of the changes made and to create baseline vibration fingerprints for your equipment. This helps track variations over time, identify early signs of instability, and maintain consistent production efficiency.
