FEEDEX K (Fig. 1, Foseco Foundry Division Vesuvius GmbH) highly exothermic feeder sleeves combine the best in class feeding performance that foundries with unsurpassed knock-off cleanliness and consistency.
The unique design of the stepped steel breaker core and optimized neck configuration allow spot feeding application to even the smallest casting contact areas, create a defined knock-off edge at the casting surface and ensure excellent sandcompaction underneath the feeder sleeve.
Since the compaction mechanism is confined to the core and not the feeder, FEEDEX K sleeves offer consistent, predictable feed metal volumes for improved process security reduce the risk of loose exothermic material falling into the feeding cavity (Fig. 2, Foseco Foundry Division Vesuvius GmbH)
