Method for producing ceramic components, more particularly ceramic components having recesses and/or hollow spaces, there being at least one sintered ceramic part present. In order to improve the handling qualities of ceramic components, the sintered ceramic part can include a carrier or carrying section which is removed in the further processing from at least one ceramic component.

Press arrangement with a further processing module

A press arrangement and a method for producing and processing compacts from powder material include a controller, a press frame, a pressing unit being disposed on the press frame for pressing the compact and having a die with a cavity for receiving powder material, at least two punches which, together with the cavity, provide a mold for a compact and at least one drive unit for moving at least one punch relative to the other punch along a pressing axis. A further processing module has at least one processing unit for machining a compact by metal cutting. The controller at least partially ejects or removes a compact from the die after pressing and, after the ejection holds the compact clamped between the punches. The controller uses the processing unit to process a compact being at least partially ejected from the die and held clamped between the punches.

Method for producing gas sensor element

A method for producing a gas sensor element (10), the gas sensor element including a diffusive porous layer (113) disposed in a measurement chamber (111) and exposed to the outside and a ceramic insulating layer (115) forming sidewalls of the measurement chamber. The method includes transferring green diffusive porous layer pieces (113x) cut in advance so as to have prescribed dimensions onto a first ceramic green sheet (110x); applying an insulating paste which later becomes the ceramic insulating layer to the first ceramic green sheet; laminating the first ceramic green sheet onto a second ceramic green sheet (120x) to form a ceramic laminate (200x); cutting the ceramic laminate along prescribed cutting lines C to obtain a plurality of gas sensor element pieces 10x; and firing the gas sensor element pieces.

Machining features in a ceramic component for use in an electronic device

A ceramic part and methods for making the ceramic part are disclosed. A green body or non-sintered part may be formed using a casting or molding process. The green body may not be sintered or may be partially sintered before machining one or more features into a surface of the green body. After machining, the component may be fully sintered to create a hardened ceramic component.

Honeycomb body with a cutout portion and method of manufacturing same

A honeycomb body having a cutout, an assembly including the honeycomb body, and a method of manufacturing. The method includes forming the honeycomb body having a matrix of intersecting walls that define a plurality of cells and channels extending longitudinally through the honeycomb body. A subset of the channels are plugged to create a plurality of plugged cells in a reinforcement region of the honeycomb body. Material is removed from the honeycomb body within the reinforcement region in accordance with a peripheral shape that passes through the plugged cells to form a cutout that extends an axial depth into the honeycomb body.
