A system for manufacturing a shell for a batting helmet includes interchangeable mold-core portions configured to form a cavity for receiving molding material. The mold-core portions include a first base mold-core portion and a plurality of inner side mold-core portions configured to form an interior contour of the shell. The mold-core portions further include a second base mold-core portion and a plurality of outer mold-core portions configured to form an exterior contour of the shell. Mold-core portions are interchangeable, removable, and replaceable from an interlocked position relative to other mold-core portions. A method of manufacturing batting helmet shells includes selecting mold-core portions corresponding to various helmet shell configurations having various protective features, assembling the mold-core portions into a mold assembly, and providing molding material into a cavity in the mold assembly. A kit of parts for making a shell for a batting helmet includes a variety of interchangeable mold-core portions.

The injection mold has a mold core including a first part and a second part. The parts are mobile relative to one another between a first injection position in which they are moved together to form an injection cavity permitting the injection of a material to form an injected part (50; 50), and a second demolding position in which they are moved away from one another to permit the demolding of the injected part (50; 50). The injection mold has at least one ejector designed to contribute to the demolding, and at least one movable intermediate plate (10; 10, 20), separate from the two parts of the mold core. The intermediate pate is arranged between the two parts of the mold core, and has at least one cutout (12; 12, 22) forming at least one part of the injection cavity of the injection mold.

A core for the moulding of a turbine engine blade, this blade including a vane extending along a spanwise direction and ending in a top, this core including a first core element to delimit a first internal cavity and a second core element of which at least one portion delimits a second internal cavity. The second cavity is situated between the first cavity and the top of the blade along the spanwise direction, and the portion of the second core element delimiting the second cavity includes a through hole, which emerges in line with an end face of the first core element to constitute a de-dusting conduit of the first cavity, this conduit traversing the second cavity from end to end while emerging in the top of the blade.

A system to manufacture an object includes a headstock, a tailstock, and a mandrel having a first end coupled to the headstock and a second end coupled to the tailstock. The system also includes an actuator coupled to one or more of the headstock, the tailstock, or the mandrel, the actuator operable to apply a force to the one or more of the headstock, the tailstock, or the mandrel, to oppose deformation of the mandrel.

An injection moulded thermoplastic preform for blow moulding to form a container, the preform comprising a lower closed base portion, a hollow body portion, a hollow transition portion between the lower closed base portion and the hollow body portion, and an upper open end portion adjacent to an upper part of the hollow body portion, wherein the closed base portion comprises a central portion which extends over at least 50% of an internal radius of a lower end of the hollow body portion and is either substantially flat or has a shallow concave or convex internal curvature, and the transition portion comprises an upwardly and radially outwardly tapering portion extending away from the central portion to connect to the hollow body portion, the tapering portion being inclined at an angle of from 1 to 20 degrees to a longitudinal axis of the preform and the tapering portion increasing in thickness from the central portion to the hollow body portion. Also disclosed is a method of injection moulding the thermoplastic preform.

A method for forming a vehicle reinforcing member (26, 28, 30). The method includes conforming a planar body of fibre reinforced material (CFRM) (504), such as a sheet or unidirectional tape, to a shape of a shape defining member (506, 900). In effect, the shape defining member (506, 900) is a core that defines an internal volume of a closed cross-section portion of the vehicle reinforcing member (26, 28, 30). The CFRM material (504) comprises continuous fibres in a synthetic matrix. The method further includes bonding a first edge portion (510) of the CFRM body (504) to a second edge portion (512) of the CFRM body (504) thereby to form the closed cross-section portion of the vehicle reinforcing member (26, 28, 30). An apparatus (800) for implementing the method, and components (e.g. vehicle reinforcing members (26, 28, 30), vehicle seats (10) and so forth) formed using the method are also described.
