Minimize Casting Scrap with Pressed Ceramic Filters
Every foundry battles daily against scrap and poor quality generated by variables in the casting process. You can reduce pouring variability by using premium pressed cellular ceramic filters from Hickman, Williams & Company.
Common foam filters introduce variability because the open area of these filters can change during manufacturing. Pressed cellular filters, however, are made to pro- vide the same open area from filter to filter. Eliminating this variability produces consistent metal flow and reduced downstream turbulence.
Extensive new research _ including high-speed video footage of the filtration process _ has proven that the design of our pressed cellular filters allows the lighter density slag/dross to be swept away from the filter face resulting in castings free of unwanted slag/dross while at the same time maintaining a consistent metal flow rate.
