A tooling fixture suitable for use in infiltrating a fibrous preform with a flow of reactant gas includes at least one wall. The at least one wall includes an outer surface and opposing inner surface defining a thickness therebetween, and a plurality of holes extending through the thickness. Each hole of the plurality of holes includes an inlet at the outer surface, an outlet at the inner surface, a transition point between the inlet and the outlet, and a first corner defined by the outer surface and the inlet. An angle of the first corner is less than 90 degrees, each hole of the plurality of holes has a first diameter at the inlet and a second diameter at the outlet, and the second diameter is less than the first diameter.

Quick release sleeve chill roll
10076863 · 2018-09-18 · ·

The present invention is a method and apparatus for quick and easy rubber sleeve exchanges on chill rolls, such as are used in film extrusion processes. The apparatus includes chill roll or mandrel, a rubber sleeve covering the exterior face of the mandrel, an automated cantilever system, and an air booster. The rubber sleeve is easily removed by tilting the mandrel and inserting a layer of air between the rubber sleeve and the mandrel, thereby allowing the sleeve to slip off the mandrel and allowing for a new rubber sleeve to be placed onto the mandrel.

UNDERCUT PROCESSING MECHANISM, MOLDING DIE, AND MOLDED PRODUCT
20180147750 · 2018-05-31 · ·

An undercut processing mechanism is attached to and used in a molding die for forming a molded product having an undercut portion, and allows demolding of the undercut portion. The undercut processing mechanism includes: a holder attached to or formed integrally with the molding die; a sliding piece configured to be slidable relative to the holder such that a mold core is moved so as to demold the undercut portion; a retaining piece configured to retain the sliding piece such that the sliding piece is slidable; and a support wall configured to support the sliding piece so as to prevent the sliding piece from being tilted when the sliding piece slides. The sliding piece forms a part of the mold core for forming the undercut portion.

ROTARY DEVICE AND SPHERICAL RECEIVING DEVICE FOR RECEIVING AT LEAST ONE ROTATIONAL MOLD
20180126606 · 2018-05-10 ·

The invention relates to a spherical receiving device for receiving at least one rotational mold, which is configured and intended to be driven to rotate in a rotational device by means of a drive wheel rolling on the outer side of the spherical receiving device. The spherical receiving device is distinguished by the fact that it has at least one guiding device which causes a drive wheel rolling on the outer side of the spherical receiving device to follow a predetermined rolling path on the outer side of the spherical receiving device. The invention also relates to a rotational device which has such a spherical receiving device and a drive wheel which is driven by means of a drive motor, said drive wheel rolling on the outer side of the spherical receiving device and driving the spherical receiving device to rotate.
