Abstract
A high throughput, automated process for coating ceramic monoliths used as catalytic converters that overcomes problems with coating monoliths individually in a mold. The monoliths are provided with end caps to cover the open functional ends, then loaded serially into an inlet channel leading to an extrusion chamber. As each monolith is pushed into the channel, one monolith enters the extrusion chamber, and the monolith just coated in the extrusion chamber is made to exit onto a finished part conveyor. Thereafter, the end caps are removed and cleaned for reuse on new monoliths yet to be coated.
