Title: Innovations by Robert S. Lund
Introduction
Robert S. Lund is a notable inventor based in Elmhurst, Illinois. He has made significant contributions to the field of mold-blowing technology, holding a total of four patents. His work focuses on improving the efficiency and effectiveness of sand mixing and blowing processes.
Latest Patents
Among his latest patents is a method of blowing cores using quick-set sand. This innovative technique involves blowing a freshly mixed quick-setting sand mix from a blow box into a mold while a plunger moves through the blow box to ensure all fluidized sand is directed into the mold. The design of the blow box includes a tube that extends downward, creating an annular gap above the blow plate. This configuration allows fluidizing air to move the bottom sand directly through the center exit in the blow plate. In cases where quick-setting sand is used, any residual sand is efficiently blown into a purge pan as the plunger advances. Conversely, with non-quick-setting sand, residual sand tends to settle and is often the first to be blown into the mold during subsequent operations.
