The new spot feeder concept FEEDEX K VAK (Foseco Foundry Division Vesuvius GmbH) is a further development of the well-proven Compressor spot feeder technology.
The current advantages, such as minimum footprint area, smallest contact area and optimum molding sandcompaction beneath were adopted from the existing FEEDEX K concept (Foseco Foundry Division Vesuvius GmbH). From the first idea to the serial stage, extensive tests were carried out. Prior to casting tests, solidification simulations were conducted for verification purposes.
Within the new concept (Fig. 1, 2 und animation VAK here, Foseco Foundry Division Vesuvius GmbH), a large part of the compressor core is heated by the highly exothermic feeder sleeve material.
