Method for manufacturing plugged honeycomb structural body, mask for forming plugging part therefor, and method for manufacturing the mask

摘要

A method for manufacturing a plugged honeycomb structural body capable of producing inexpensively in a short period of time with reducing the amount of industrial waste is provided. The method comprises photographing at least one end face of a honeycomb structure body to acquire an image data to specify the shapes and locations of cells to be plugged and cells not to be plugged, preparing a mask for forming plugged portions having hole portions connectable with the cells to be plugged and projections engageable at least with one part of the honeycomb structure body based on the image data using a photofabrication method, and forming plugged portions by introducing a ceramic slurry into the cells to be plugged via the hole portions of the mask, while securing the mask to the end face of the structure body by using the projections to be engaged at least a part thereof.
