Thanks to the tumbling process using water and abrasive substances, the burrs from Zamak fusion, typical of metal parts, can be removed. To polish metals, we use a Rösler ST22 rotary vibrator with a noise protection cover for:

- Deburring
- Heavy deburring
- Descaling
- Smoothing
- Dry polishing
- Superfinishing
- Pre-galvanisation
- Auto-tumbling

During the tumbling stage, urea-resin abrasives are used to provide sufficient elasticity for a good level of abrasion, but with a very fine finish, without any dents and with a very low level of roughness, which is particularly recommended for objects in light alloys and for pre-galvanisation processes on any type of metal: aluminium, steel, brass, Zamak, etc.

The advantages of RÖSLER vibrator finishing or tumbling are:

- Cost savings: using these systems reduces manual input and the related costs.
- Speed: the processing times are much faster than when using traditional technologies.
- Flexibility: different sized batches and quantities can be handled
