This thesis is a result of cooperation between the department of Mechanical Engineering of Blekinge Institute of Technology and Tetra Pak in Lund. The name of this thesis is Noise Reduction Study of Converting Equipment. Tetra Pak struggles with a very high noise level, that’s caused by their converting equipment. My task is to localize the source of the noise and then generate a number of solutions. I generated three types of solution. Then the solutions were weighted. The winning solution was surface treatment of the cooling rollers. Next step was to find treatments that are suitable for this application. Four types of treatments were found. Then I had to do a weighting of them. The treatment that won was the Tribobond 44. Tribobond 44 is made through the Physical Vapour Deposition process. The coating consists of Diamond like Carbon layers.
