20080236724 | METHOD FOR MANUFACTURING HONEYCOMB STRUCTURE - A method for manufacturing a honeycomb structure includes molding a honeycomb body having a number of cells disposed in parallel with one another in a longitudinal direction, firing the molded body placed on a spacer disposed on a bottom plate of a firing jig and bonding a plurality of the fired bodies together. In the firing treatment, the spacer is disposed on at least two locations in a plan view of the molded body placed on the spacer so that a center of gravity of the molded body is sandwiched in the longitudinal direction. The spacer is disposed with respect to each of middle points between the center of gravity and centers of gravity of end faces of the molded body so as to include both an area on a side of the center of gravity and an area on a side of each of the end faces. | 10-02-2008 |
20090199953 | METHOD FOR MANUFACTURING HONEYCOMB STRUCTURE - A method for manufacturing a honeycomb structure includes molding a ceramic raw material to manufacture at least one honeycomb molded body having a plurality of cell walls extending along a longitudinal direction of the at least one honeycomb molded body to define cells. The honeycomb molded body is fired to manufacture a honeycomb fired body. A honeycomb block is manufactured by using the honeycomb fired body.

20120111477 | METHOD OF MANUFACTURING HONEYCOMB STRUCTURE AND DEGREASING APPARATUS FOR HONEYCOMB MOLDED BODY - A method of manufacturing a honeycomb structure including a honeycomb unit includes forming a honeycomb molded body having a plurality of cells extending from a first end face to a second end face of the honeycomb molded body along a longitudinal direction of the honeycomb molded body and separated by a plurality of cell walls, placing the honeycomb molded body in a degreasing apparatus so that the first end face faces downward and the second end face faces upward, feeding introduced gas into the degreasing apparatus, degreasing the honeycomb molded body at a temperature of approximately 200° C. to approximately 400° C., and firing the degreased honeycomb molded body at a temperature of approximately 500° C. to approximately 900° C. to obtain the honeycomb unit. | 05-10-2012 |
20120160395 | METHOD FOR MANUFACTURING HONEYCOMB FILTER - A method for manufacturing a honeycomb filter includes applying a first sealing material paste to a side face of one of honeycomb fired bodies to form a sealing material paste layer thereon. Another of honeycomb fired bodies is laminated on the first sealing material paste layer to manufacture an aggregated body of honeycomb fired bodies. The aggregated body of honeycomb fired bodies is heated so that the first sealing material paste layer is dried and solidified to produce a ceramic block. A second sealing material paste is applied to a peripheral face of the ceramic block in accordance with irregularities formed thereon so that an outer peripheral surface of the honeycomb filter has surface irregularities thereon. The second sealing material paste is dried and solidified to form a sealing material layer on the peripheral face of the ceramic block. | 06-28-2012 |
20130056134 | METHOD FOR CUTTING HONEYCOMB MOLDED BODY AND METHOD FOR MANUFACTURING HONEYCOMB STRUCTURE - A method for cutting a honeycomb molded body includes applying laser in a wavelength range of from about 0.7 μm to about 2.5 μm to the honeycomb molded body to form a cut guide groove on a periphery of the honeycomb molded body. The honeycomb molded body is made of a material including silicon carbide. The honeycomb molded body is manufactured by extrusion molding. The honeycomb molded body has a number of cells, a cell wall interposed between the cells and a peripheral wall formed on a side face of the honeycomb molded body. The cells are placed in parallel with one another in a longitudinal direction of the cells. The honeycomb molded body is cut along the cut guide groove to a predetermined length using a wire. | 03-07-2013 |
