A mandrel for a molding process includes a first portion and a second portion that form a mandrel having a channel between the first and second portions. At least one locking pin is configured to urge the first and second portions away from each other to establish a gap in response to inserting the locking pin into the channel along a respective end of the mandrel. A molding apparatus and method of forming a matrix composite component are also disclosed.

The invention relates to a mold for manufacturing a plastic part, including a first element and a second element forming, in the closed position of the mold, a cavity corresponding to the part to be manufactured, in which the second element includes at least one system for making molding openings in said part, said system including at least one member forming a cavity of an opening for the finished part, said member being movable relative to the second element in the closing direction of the mold, between a retracted position and an position extending into the cavity. The system includes at least one positioning means for positioning the member in the extended position relative to the first element, said system being sized such that, in the extended position of the member, the distance between a surface of the member bearing on the plastic material and the first element enables the formation of a thin layer of plastic material having a repeatable thickness.

Provided is a forming device including: a lower die; an upper die for forming a laminated body along the surface shape of the lower die by pressing the laminated body against the lower die; a pushing force generating mechanism that generates pushing force for pressing the upper die against the lower die; and a control unit that controls the pushing force generating mechanism, the upper die has a plurality of forming members aligned in the longitudinal direction, the pushing force generating mechanism has a plurality of pushing force generating units connected to the plurality of forming members and configured to generate pushing force for pressing the forming members against the lower die, and the control unit controls the plurality of pushing force generating units so as to press a pair of forming members arranged adjacent in the longitudinal direction toward the lower die at different timings from each other.

A mandrel for a molding process that includes a first portion that has a first portion outer surface, a first portion inner surface, a first portion first end, and a first portion second end. A thickness of the first portion first end is greater than the first portion second end. A second portion has a second portion outer surface, a second portion inner surface, a second portion first end, and a second portion second end. A thickness of the second portion first end is smaller than the second portion second end. The first portion inner surface engages the second portion inner surface to form a mandrel that has a constant cross-section.

Provided is a compression molding die. The die can be used for compression molding an I-shaped part without the need for machining. The molding die comprises: an outer mold with an inner diameter of d; an upper pressing disc, a lower pressing disc and a huff mold with the same outer diameter of d and the same inner diameter of f; an upper mold; a lower mold; and a core mold with a diameter of h. The upper pressing disc, the huff mold and the lower pressing disc, which are movable vertically, are arranged in the outer mold in a vertically spaced manner; the vertically movable upper mold extends into the upper pressing disc, and the vertically movable lower mold extends into the lower pressing disc; the outer mold, the upper mold, the upper pressing disc, the huff mold, the lower pressing disc and the lower mold define a cavity.

A device (1) for producing a moulding of surface properties comprises a housing (3) having a pressure plunger (4) mounted on or in the housing (3), which can be moved and can be pressed on a surface (2), which pressure plunger has a blank carrier (5) comprising a pressure surface (6) which can be pressed on the surface (2), on which pressure surface a moulding blank (7) comprising a moulding layer (9) made of a curable material can be secured in a detachable manner. The device further comprises a curing device (12) arranged on or in housing (3), with which the curable material of the moulding blank (7) can be cured while being pressed on the surface (2).

A press device for manufacturing compacted tablets from at least one mixture in powder form, including at least one compaction assembly including a lower punch and an upper punch each having an active compaction surface and placed on either side of a die. The lower punch has a longitudinal recess open on the side of the die, inside of which is mounted a central rod which is translatably mobile relative to the lower punch. The central rod is coupled to the lower punch by a resilient link provided so as to hold, in an inoperative position, the central rod in a maximum deployed position in which the central rod protrudes relative to the active surface of the lower punch. The invention also relates to a specific compaction method and to a multi-layer compacted tablet with a recess.

A mandrel for a molding process that includes a first portion that has a first portion outer surface, a first portion inner surface, a first portion first end, and a first portion second end. A thickness of the first portion first end is greater than the first portion second end. A second portion has a second portion outer surface, a second portion inner surface, a second portion first end, and a second portion second end. A thickness of the second portion first end is smaller than the second portion second end. The first portion inner surface engages the second portion inner surface to form a mandrel that has a constant cross-section.

A preform station for forming a flexible semi-finished product and for transforming a flexible semi-finished product into a geometrically stable preform is provided. The preform station comprises a first pin array having a multitude of pins, on which the semi-finished product can be draped. Furthermore, the pins are movable along their longitudinal directions in order to form the flexible semi-finished product. Furthermore, the preform station comprises an activation device for activating a binder of the semi-finished product such that the semi-finished product can be transformed into the geometrically stable preform.
