The surface conditioning is characterized by an oxidizing flame treatment.

Abstract: Method and apparatus for mixing foundry mold catalyst and carrier gas when the catalyst is in the liquid phase and the carrier is in the gaseous phase at standard conditions of temperature and pressure. The catalyst liquid is heated to vaporize it and the resulting catalyst gas is then mixed with the carrier gas under control of an automatic gas flow regulator which maintains the mass ratio between the catalyst gas and the carrier gas at the desired level in the gaseous mixture notwithstanding variations in the flow rate of either or both gases. The gaseous mixture is then blown through foundry molds and cores to cure the resin binder therein.
