METHOD AND DEVICE FOR APPLYING WASHCOAT SUSPENSIONS TO A MOLDED ARTICLE

摘要

The invention relates to a method for removing an excess of a liquid from a molded article that comprises two opposite planar faces and interior cavities and/or channels to be coated with the liquid. The inventive method is characterized by removing in a first removal step, once the liquid has been introduced into the interior cavities and/or channels, the major portion of the excess liquid under the influence of an external force, and removing in a second removal step the excess liquid remaining in the molded article after the first removal step by contacting the molded article with a porous and/or channel-bearing support on the very face where the excess was removed. The pore and/or channel diameter of the support is smaller or equal the diameter of the interior cavities and/or channels of the molded article.
