ABSTRACT:
An apparatus and method for forming foundry cores and molds of superior hardness and uniformity in a wide range of sizes includes staging hoppers for storing a first mass of sand coated with a catalyst-polymerizable resin film, and a second mass of sand coated with a catalyst film for polymerizing the resin. In forming the cores or molds these masses are simultaneoulsy and evenly dispersed into a high velocity carrier air-sand stream and directed through a static mixer, wherein the resin and catalyst-coated sand particles are intermingled and at least a partial integration of the films takes place, into a shaping mold cavity, wherein the sand mixture hardens into a desired shape. Because the process is fast and continuous, and allows the use of resin-catalyst systems having very fast hardening times, the apparatus and method are particularly well suited to high volume foundry operations wherein it is desirable to reduce the residence time required in the shaping molds to minimize the number of molds and the storage space required.
