Spot Feeders for Mold Filling

Jan. 5, 2021
The compressor core is heated by highly exothermic feeder sleeve material, reducing the contact between the compressor plate and green sand, improving feed performance.

The FOSECO Feedex K VAK spot-feeder concept for mold-filling is a further development of the earlier Kompressor spot feeder technology. Advantages of that product, such as minimum footprint area, smallest contact area and optimal molding sand compaction were adopted from the preceding Feedex K concept. Extensive testing was conducted of the new concept and solidification simulations were conducted for verification purposes.

With the Feedex K VAK process, a large part of the compressor core is heated by the highly exothermic feeder sleeve material. This significantly reduces (-50%) the contact area of the compressor plate to the green sand compared to the Feedex VSK feeder. The result is an improved feed performance.

Feedex K VAK feeders are used where smallest footprints and minimum contact areas are required.

The application is as simple: The self-centring geometry eases the application of the feeder sleeve onto the fixed pin. The feeder residue can be knocked-off easily with little force. Learn more at www.foseco.com
