Bulk Deflashing machines

SBS loop belt machine

SBSK loop belt machine

Components are transported to the loop belt deflashing machine via a feed conveyor and a vibrating feed chute. The special design of the loop belt with built-in cams, allows parts transport like in a screw conveyor. The components travel at a defined speed through the deflashing zone.

The components are deflashed by one or more turbines.

Residual blast media is removed in a rotating screen drum. The components discharged from the machine are largely dust-free and ready for subsequent operations.

Key features of loop belt machines

  • 1–3 turbines, continuous operation
  • For the automatic bulk deflashing of
  • large parts quantitiessmall to medium-size components

Typical applications:

  • Housings, covers and sockets for electrical components
  • Housings and covers for circuit breakers and contactors
  • Pan handles
  • Ashtrays

WTS Tunnel machines

WTS Tunnel machines

Tunnel deflashing machines were developed primarily for deflashing thin-walled and fragile components.

The tunnel transport system transports fragile components at a defined speed through the deflashing zone, turning them over continuously to ensure that they are deflashed from all sides. A given distance is maintained between individual components to prevent them from touching each other and becoming damaged.

Sturdier components are fed into the machine in bulk by a feed conveyor and a load funnel.
Key features of WTS tunnel machines

  • 1–2 turbines, continuous operation
  • For the automatic deflashing of

    • fragile, medium-sized components in  a single piece continuous process
    • less fragile components in bulk

Typical applications:

  • Meter housings and terminal  bars
  • Fragile switch components
  • Steam iron handles and other handles with complex shapes
  • Terminal housings
  • Covers
  • Fragile miniature circuit-breaker housings
