Semi-automatic desanding inside of cylinder head blocks

Semi-automatic desanding inside of cylinder head blocks

MAN has been awarded the title “Truck of the Year” for the sixth time in 2006.

Blasting in the economic turnaround

The jury was especially impressed by the thoroughness the engineers applied to the development. Freeing the cylinder head blocks from sandy deposits is done equally thoroughly at the truck manufacturer – with a semi-automatic shot blast system by Rösler.

To save manpower and manufacture such that reproduction is possible – right now these are two of the most common demands with regard to cost-effective production. In order to meet

these requirements in the field of removing residues from the inside of sand cast components (in this case cylinder head blocks of 4 and 6-cylinders) MAN will, in future, replace the manual shot blast process with a semi-automatic procedure in its factory in Nuremberg. Rösler Oberflächentechnik was asked to design a shot blast system which shot blasts the components mentioned with a mass of 25 to 80 kg. 

Cost savings due to a high throughput rate

Apart from effective cost savings due to the fact that less personnel is needed, this individual solution offers an eight-times higher component throughput rate. 

As an all-round supplier, Rösler GmbH is an international market leader in the production of surface finishing, shot blasting machines, painting systems and preservation lines  as well as process technology for the rational surface finishing of metals and other components. Besides the German plants in Memmelsdorf and Hausen, the Rösler Group has branches in Great Britain, France, Italy, The Netherlands, Belgium, Austria, Switzerland, Spain, Singapore, Brazil, South Africa and USA.
