Technical description

The raw work pieces are placed on the wire mesh belt by hand or a handling device. They are passing through the de-flashing zone at a preset, adjustable speed, while being exposed to the blast stream of the two turbines located above and below the belt. After de-flashing the finished work pieces are passing through a blow-off station where any residual blast media is removed from the work piece surface. The work pieces are then discharged through a chute.

For the automatic de-flashing of:

Thin walled, fragile work pieces

Small to medium size work piece quantities

Small to medium size work pieces

Typical applications:

Switch housing


Flat iron components

Circuit breakers

Special equipment:

Parts carrier system for individual parts which are sensitive to impact and are placed on a parts carrier by handling systems or robots
