Cryogenic media-blast deflashing

AWS 60 // AWS 60+

The AWS 60 is a media-blasting machine for the cryogenic deflashing of rubber or plastic moulded parts. The very well-insulated machine cell, in combination with 2-stage dust extraction, guarantees low nitrogen consumption with effective deflashing. Loading occurs fully automatically via a motor-operated door. Energy-efficient drives and high-quality materials, good media-blasting performance and thus short batch times, as well as low space requirements, are other features of the AWS 60.

The S7-1500 controls, in combination with the button panel and barcode reader, allow for user-friendly operation of the system. The entry and saving or external saving of formula data records guarantee a high degree of reproducibility and security for the cryogenic deburring.

SUSTAINABLE RELIABILITY

Internal granulate sifting

  • Continuous separation of dust and residual flashing from the blasting media
  • Blasting grain in the correct size and purity for effective abrasive media-blasting
  • Sustainable, reproducible media-blasting performance even in multi-shift operation

Additional cooling

  • Cooling and absorbing of moisture within the machine
  • Compensation for the air humidity which enters during the loading and unloading process
  • Minimisation of the set-up and auxiliary process times for downtimes of more than 8 hours

AWS 60 with fully automated loading door

The motor-operated automatic loading door, in combination with the light gate provided, quickly moves between open and closed. It can consequently reduce set-up times in semi-automatic operation.

AWS 60 with fully automated loading door and loading

Fully automated operation of the machine can be implemented here. The moulded parts to be media-blasted are automatically fed into the machine via a conveyor belt system. Emptying after the end of the batch and refilling then occurs automatically. This can also be combined with upstream and downstream conveyor technology through to batch tracking by means of barcodes or RFID technology. In combination with the safety technology supplied, we naturally comply with all of the safety regulations here.

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 active media-blasting angle adjustment, patent pending, allows the media-blasting operating area to be adjusted automatically within the processing basket.

Processing basket

The basket can be swapped and a variety of basket perforations are therefore available. Tailored exactly to your requirements according to the moulded part sizes. Loading occurs manually or automatically through the fully automated loading door. The basket is automatically emptied onto the emptying sieve by means of the integrated roller rails.

Emtpying sieve

The external vibration sieve works with frequency-controlled modern vibration motor technology. This allows the supply and sieve speeds to be set optimally. As standard, the emptying sieve is single-level with a changeable sieve so you can respond to a variety of moulded parts. We can also offer customised multi-level emptying sieves.
