A centrifuge plate is disclosed which is intended for casting housing ends of hollow fiber filter modules and can be rotated around a centrifuge axis. The centrifuge plate includes at least two bearing elements arranged diametrically with respect to the centrifuge axis and provided for supporting a housing of a hollow fiber filter module to be cast, wherein each bearing element is rotatably supported on the centrifuge plate around a bearing axle which is parallel to the centrifuge axis.

A column or other elongate molded part is molded using an elongate tubular mold having a closed end, an open end and a flexible sidewall. After the column or other molded part is formed, it is extracted from the mold by pulling the column or other molded part axially through the open end of the mold. The column may be extracted using an expandable plug or gripper that is inserted into the interior of the column or other molded part through the open end of the mold. The expandable plug or gripper is expanded to engage an inner surface of the elongate molded part.

According to one exemplary embodiment, the rotatable tube is made of metal and includes a plurality of apertures configured to permit the transmission of actinic radiation.

The invention relates to a method for the construction of a shaped body from photopolymerizable material by using lithography-based generative production (rapid prototyping), in which a layer of liquid photopolymerizable material is defined on a production platform (1, 2, 3, 4), the layer is polymerized in an exposure region having a predetermined contour by exposure, a further layer of photopolymerizable material is defined on the polymerized layer, the layer defined last is polymerized by exposure in an exposure region having a predetermined contour for the layer defined last, and the latter two steps are repeated until a shaped body having a predetermined shape has been formed by the sequence of cured layers with contours predetermined layer by layer, wherein ink is applied onto at least one layer inside the predetermined contour, wherein the production platform is suspended moveably and wherein the production platform is brought, after the polymerization of a layer in a processing station for polymerizing a layer, by movement to an ink application station as a further processing station in which ink is applied position-selectively to the layer formed last, after which the production platform is moved again to the processing station for polymerizing a further layer, characterized in that the movement of the production platform between various processing stations is carried out by rotating a drum-shaped carrier which holds the production platform on its circumference, around a horizontal or vertical axis of rotation, wherein the processing stations are disposed distributed around the axis of rotation of the drum shaped carrier.

An apparatus includes a first tube, a motor, a support, and a tubular mold having an inside surface. The motor rotates the first tube and the tubular mold. A vacuum bag is disposed over the inside surface of the tubular mold. A plurality of second tubes and a plurality of third tubes extend radially from the first tube. The second and third tubes establish fluid communication between the first tube and a tubular space defined between the bag and the inside surface. A resin injection system is configured to inject a resin into the tubular space by conveying the resin first through the first tube, then injecting the resin through the plurality of second tubes into the bag such that the resin flows over a surface of a layer disposed inside the tubular space. A vacuum system is configured to produce a vacuum through the plurality of third tubes.
