    摘要： There is provided a mold for extrusion forming of ceramic articles which is excellent in wear resistance and can remarkably decrease forming defects in the vicinity of outer peripheries thereof. The mold for the extrusion forming of the ceramic articles includes a die 1 having a plurality of back holes 9, and slits 8; a back pressing plate 12 and a back spacer 13 to adjust the amount of the kneaded clay to be supplied; and a pressing plate 11 and a spacer 10 to regulate the shape and size of the formed ceramic article. At least a portion of the supply end 22 of the die 1 which overlaps with the back pressing plate 12 is flattened, and a surface roughness (Ra) thereof is in a range of 0.05 µm to 10 µm.

    摘要： A honeycomb extrusion apparatus includes first (323) and second (327) vanes with respective first (325) and second (329) face portions. First (Wl) and second (W2) axial widths of a circumferential feed area (321) are respectively defined between the first (325) and second (329) face portions and the outer feed surface (311) of the die body (201). In further examples, methods include the steps of selectively adjusting the first axial width (Wl) and the second axial width (W2) of the circumferential feed area (321) by respectively adjusting the first (323) and second (327) vane relative to the mask (225). In further examples, a honeycomb extrusion apparatus includes a plurality of mask segments (1209a, 1209b) that each includes an inner peripheral surface portion (1501). Each of the plurality of mask segments (1209a, 1209b) are independently adjustable along a respective radial axis (1503).

    摘要： A process for forming tiles of porcellainized ceramic stone by extrusion, comprising the following operations:

    preparing at least two pastes, typologically defined as porcellainized ceramic stone, having different colours;
    feeding said at least two pastes into a mixing device and/or injecting them directly into the extruder chamber (6);
    subjecting the mixed material to the action of a screw extruder (7);
    subjecting the mass advancing within the extruder (6), downstream of the screw (7) and upstream of the die braking system, to the action of at least one flow deviator means (9,10,11,12);
    from the extruded web obtained in this manner, separating portions corresponding to the formed objects.
