Vital features ensure the consistent quality and process reliability necessary for thermoset deflashing.
Deflashing systems
Blast wheel technology
To accelerate the deflashing medium to the high velocity required for efficient deflashing, it is most common to use blast wheels. Blast wheels use centrifugal force to accelerate the deflashing medium. Compared with air blast systems, their specific energy consumption is very low. Blast wheels provide the high coverage needed for most applications.
Air blast systems
Contrary to blast wheels, air blast guns are used for applications where deflashing is desired in defined locations only, or where only small quantities of deflashing medium are required. Air blast guns are used in combination with blast wheels
to deflash difficult to access areas such as bores or pockets.

Deflashing medium reconditioning
Screening unit
Multi-stage screeners and/or airflow separators continuously remove flash, flash particles, fibers and spent deflashing medium from the blast media being circulated within the machine.
Cascade separator
A cascade separator continuously removes flash, flash particles, fibers and spent deflashing medium from the circulating blast media.
Deflashing medium replenishment
Automatic, sensor-controlled replacement of consumed deflashing medium ensures consistency in deflashing medium quality (operating mixture).
Dust collector/dust extraction
Exhaust air is freed of dust by special, highly efficient filter cartridges. An automatic backcleaning system for the filter cartridges (the machine need not be halted) permits 24-hour operation.
Extraction from the deflashing zone
Dust is extracted from the deflashing chamber. Depending on the application , various methods are used to recover serviceable deflashing medium and return it to the process.
Antistatic systems
To prevent dust from re-depositing on the deflashed components due to static charges, all our machines are equipped with an antistatic fluid spray system. Antistatic fluid contained in a tank is sprayed into the deflashing chamber via nozzles.
As an alternative to the manual water/antistatic metering unit, we also offer an automatic dosing system (connection to water main, selection of mixing ratio via the PLC).
Design with compressed air Cleaning/blow-off of the deflashed components is tailored to the type of components being processed.
