Method of making a cross-flow honeycomb structure |
摘要 |
The present invention is directed to a novel method for extruding a honeycomb structure. The method comprises the use of an extrusion die with primary and secondary feed holes and associated discharge slots, wherein extruded material exits the primary discharge slots at a faster rate than the secondary discharge slots. The faster moving extruded material buckles and forms a corrugated layer in between the two secondary extruded layers. The secondary extruded layers form straight cells. The material to be extruded maybe ceramic, plastic or metal.
