ABSTRACT OF THE DISCLOSURE In foundry core-blowing, a blow box snugly fits a plunger which moves through it during the blowing step. In effect, the plunger pushes all of the fluidized sand mix out of the blow box and into the core box. This solves problems which have long empeded the use of quick setting sand mixes in blowing of cores and the like. With more conventional sand mixes better and more uniform packing of the sand in the mold is believed to be achieved. Two measuring feeders are provided supplying two different sand mixes which are non curing when separate but fast setting when mixed. They are mixed in a rapid mixer, dumped into a charging tube which quickly dumps the mix into a blow box. The plunger moves through the charging tube and then through the blow box, cleaning both and aiding in the blowing of all of the sand mix into the mold or the blow passage leading to it. This may be in the form of a blow tube which has at its tip an internal lip which breaks off any residue or plug retained within this tube.
