The current advantages, such as minimum footprint area, smallest contact area and optimum moulding sand compaction beneath were adopted from the existing FEEDEX K concept. 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, a large part of the compressor core is heated by the highly exothermic feeder sleeve material.
• This significantly reduces the contact area of the compressor plate to the green sand by 50% 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 as with the VSK product line. The self-centring geometry eases the application of the feeder sleeve onto the fixed pin. Furthermore, the feeder residue can be easily knocked-off with little force.
The FEEDEX K VAK feeder series is based on the proven FEEDEX V-feeder product line.
