Cryogenic media-blast deflashing

AWS 08

The AWS 08 is optimised for the economical cryogenic deflashing of batch volumes of up to 10 litres. As a result, it obtains optimal media-blasting results on a wide range of moulded part geometries. Thanks to the media-blasting angle adjustment, patent pending, it is possible to flexibly employ the machine in two operating modes. In addition, frames for holding moulded parts or special components can be installed in the media-blasting areas in both media-blasting variants. For cryogenic deflashing the AWS 08 particularly excels with small batches thanks to its speed, clean media-blasting results and its operating efficiency, as well as its flexibility in horizontal and vertical media-blasting operation. Another advantage for the deep cold deflashing is the flexibility in the horizontal and vertical media-blasting operation.

One machine, two operating modes

Horizontal media-blasting operation

  • Horizontal, closed removable basket (wire mesh cylinder)
  • Gentle media-blasting process in closed basket system
  • Optimal circulation of the components

Vertical media-blasting operation

  • Vertical open removable basket (perforated basket)
  • High performance media-blasting with optimal blasting pattern
  • Adjustment of the media-blasting angle to the fill level

Data management

Simple and secure data handling with integrated USB and LAN interfaces. Formulas can be called up simply and securely using the barcode reader.

Active media-blasting angle adjustment

The entire processing area can be media-blasted thanks to the active media-blasting angle adjustment, patent pending.

Quick-change basket system

With the quick-change basket system for horizontal and vertical operation, baskets with freely selectable perforations / mesh widths are available. The media-blasting basket is mounted manually into the media-blasting system and is filled and emptied outside the machine. Set-up times can be minimised using additional baskets. Alternative receiving frames or basket structures are possible.
