The lack of flexibility and unsatisfactory powder coating qualities at external job shops induced a Dutch manufacturer of industrial furniture to bring its coating operation in-house. Unlike its competitors, ML Constructie decided to also perform paint preparation by shot blasting in-house with an automatic shot blasting machine from Rösler. Compared with manual processes, the shot blasting cycle times are not only eight times faster, the
automatic solution also produces better qualities at lower costs.

Since manual blast operations are hard and exhausting, it is very difficult to find and keep the people for this kind of work. With the Rösler blast machine, however, employees must only place workpieces onto the respective fixtures and remove them after the blast process.

Another significant contribution towards a better working environment is the low noise emissions, which are considerably lower than manual blast rooms. Moreover, the automated shot-blast process is eight to 10 times faster, while another benefit is the blast machine’s two rails in ‘Y’ design. This configuration allows the operator to place workpieces onto the fixture at one rail branch, while workpieces from the other rail branch undergo blasting. Therefore, unproductive idle equipment times aremore or less a thing of the past. Last but not least, the overall blast cleaning quality is considerably better.

“In the automated shot-blast process, blast media gets into even the tiniest workpiece
corners,” says Ben Luizink, co-owner atML Constructie.”This is nearly impossible with manual shot-blasting operations. Furthermore, the Rösler shot-blast machine is very
tight and emits practically no dust. Since we are coating the workpieces in the same production hall, this is a huge benefit.”
