摘要： A method of producing a microparticle includes providing a mould assembly, which comprises two moulds that comprise an upper mould and a lower mould, positioning the mould assembly in a closed position, wherein the two moulds define a micro-cavity to exert pressure on a moulding material within the micro-cavity to form the moulding material into a microparticle, and positioning the mould assembly in an open position, wherein the microparticle adheres to one of the two moulds of the mould assembly.

摘要： A method for producing a conductive honeycomb structure includes: a forming step of extruding a forming raw material to obtain a honeycomb formed body; a drying step of drying the honeycomb formed body to obtain a honeycomb dried body; and a firing step of firing the honeycomb dried body to obtain a honeycomb fired body. The forming step includes controlling a volume fraction of a portion that can form pores of the honeycomb formed body so that an absolute value of a difference in the volume fraction of the portion that can form the pores in predetermined regions of the honeycomb formed body relative to a previously set, predetermined porosity of the honeycomb fired body is within 0.5%. The predetermined porosity is a porosity preset for each of the predetermined regions of the honeycomb fired body.

摘要： Methods for extruding a ceramic-forming mixture through a honeycomb extrusion die (10), methods for forming a green honeycomb extrudate from a ceramic-forming mixture, methods of preparation of a honeycomb extrusion die (10) that extrudes a ceramic-forming mixture, and systems including a honeycomb extrusion die (10), ceramic-forming mixture, and abrasive flow media. The method of extruding a ceramic-forming mixture through a honeycomb extrusion die (10) includes conditioning the honeycomb extrusion die (10) by extruding an abrasive flow media through the slots (20) of the die (10) prior to extruding the ceramic-forming mixture through the slots (20) of the die (10). The abrasive flow media includes abrasive inorganic particles dispersed in a flowable carrier. The ceramic-forming mixture includes one or more types of inorganic ceramic-forming particles. The abrasive inorganic particles in the flowable carrier have a particle size distribution that corresponds to that of at least one type of the ceramic-forming particles in the ceramic-forming mixture.

摘要： The instant invention describes an extruder for shaping clay or similarly pliable materials into desired shapes. The extruder comprises an operational section, a cassette, and a die. The operational section comprises a plunger, a means for controlling movement of the plunger, a means for supplying electricity, and a body to provide an exterior housing. The cassette, which is removably attached to the operational section, comprises a cavity for holding extrusion material through which the plunger will pass. The die comprises an aperture used to shape the extrusion material and is able to he attached to the cassette.

摘要： A tool die for forming a green ceramic body. The tool die has a wear resistant coating that is deposited on a substrate and has an outer or free surface having a morphology that provides a mean roughness in a range from about 0.03 μm up to about 0.8 μm Rq. In one embodiment, the wear resistant coating has multiple alternating layers of fine grained and coarse grained materials. Methods of making the tool die and wear resistant coating are also provided.

摘要： A honeycomb extrusion die body (401) including inlet (414) and exit (402) faces, and a plurality of pins (406) on the exit face (402) defining a matrix of intersecting wide slots (425) and narrow slots (427). The wide slots (425) have an exit width (W1) greater than an exit width (W2) of the narrow slots (427). The die body (401) further includes feedholes (422) at the inlet face (414) and intersecting with inlet portions (416) to the wide slots (425) and/or the narrow slots (427). Some of the pins (406) defining the wide slots (425) include a first surface indentation feature (430) that is (i) located between the inlet portion (416) and the wide slot exit and (ii) spaced away from the wide slot exit. Some of the pins (406) defining the narrow slots (427) include a second surface indentation feature (434) that is (i) located between the inlet portion and the narrow slot exit and (ii) spaced away from the narrow slot exit.
