    Abstract: A method of plugging a honeycomb body is disclosed herein, the method comprising: applying a mask layer to a honeycomb body comprising a plurality of channels; forming a plurality of holes in the mask layer such that the plurality of holes are aligned with the plurality of channels; positioning a nozzle defining an opening proximate the mask layer; moving at least one of the nozzle and the honeycomb body relative to one another; and passing a plugging cement through the opening defined by the nozzle against the mask layer such that the plugging cement passes through the plurality of holes in the mask layer and enters the plurality of channels of the honeycomb body.

    Abstract: Centering apparatuses and methods for precision placement of a product or component, such as a ceramic honeycomb body, prior to a post-production processing steps are provided. In particular, after extrusion of a component or ware, the component or ware oftentimes requires one or more post-production processing steps in order to obtain a final product. The centering apparatuses and methods described herein provide for the precise and accurate centering of the product (or component) prior to performing these post-production processing steps, thereby obtaining repeatable, consistent, high-quality final products.

    Abstract: Systems and methods for cutting through one or more extrudates to form one or more honeycomb bodies are provided. The systems described herein provide a low inertia vibratory cutting system configured to cut through extrudate to form honeycomb bodies, where the vibratory cutting system comprises a thin, low-inertia cutting element, and one or more sets of fluid bearings configured to mitigate or lessen out of plane vibrations of the cutting element to provide a more stable cutting element. In some examples the vibratory cutting system comprises two sets of fluid bearings arranged at two locations on the cutting element that are configured to mitigate out-of-plane vibrations on the cutting element and between the two locations. In some examples, the cutting element is double-sided to allow for single-sided or double-sided cutting operations.

    Abstract: A method of manufacturing a honeycomb structure includes providing a honeycomb body having a first contour extending between opposing first and second ends and chamfering a corner of the first end in a radial and axial direction toward the first contour to form a second contour. The method further includes removing material in an axial direction toward the second face to form a third contour, chamfering a corner of the third contour in a radial and axial direction toward the second end to form an end contour, and removing material in an axial direction toward the first face to form a fourth contour. Removing material to form the fourth contour substantially removes the second contour and the end contour.
