The invention relates to a press device for manufacturing compacted tablets from at least one mixture in powder form, comprising at least one compaction assembly comprising a lower punch (3) and an upper punch (4) each having an active compaction surface and placed on either side of a die, in which 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, characterized in that the central rod is coupled to the lower punch by means of 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.
Constant cross section mandrel for CMC components
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.
DEVICE AND METHOD FOR PRODUCING A MOULDING OF SURFACE PROPERTIES
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).
FIBER-BASED PACKAGING CAPSULE AND A METHOD OF PRESS-FORMING THE SAME
A fiber capsule and a method of compression molding a fiber-based packaging capsule, includes the steps: forming a raw capsule of a loosely bonded fiber mat, which capsule has an opening, positioning the raw capsule of the loosely bonded fiber mat on the inside of a substantially rigid mol having inner surfaces defining the molded outer surfaces of the fiber-based packaging capsule, compression molding the loosely bonded fiber mat by the insertion of a pressurizable compression member through the opening, and pressurizing the pressing device at a temperature of 150-250 degrees C.?, preferably 160-200 degrees C., and at a pressure of 100-5000 bar, preferably 300-1200 bar. The compression molding may take place by reshaping the reshaping pressing device and pressing the inside of the capsule against the inner surfaces of the rigid mold so that a cohesive fiber-based packaging capsule is obtained.
Compression molding die for I-shaped part
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.
PRESS MOLDING METHOD OF A CUP SHAPED FIBER PRODUCT, A FIBER PRESS MOLD AND A CUP SHAPED FIBER PRODUCT
A fiber capsule and a method of compression molding a fiber-based packaging capsule, includes the steps: a raw capsule of a loosely bonded fiber mat is formed, which capsule has an opening; the raw capsule of the loosely bonded fiber mat is positioned on the inside of a substantially rigid mold having inner surfaces defining the molded outer surfaces of the fiber-based packaging capsule; the loosely bonded fiber mat is compression molded by the insertion of a pressurizable compression member through the opening. The pressing device is pressurized at a temperature of 150-250 degrees C.. The compression molding takes place by reshaping the reshaping pressing device and pressing the inside of the capsule against the inner surfaces of the rigid mold so that a cohesive fiber-based packaging capsule is obtained.
MULTI-LAYER TABLET WITH RECESS, DEVICE AND METHOD FOR COMPACTING SUCH A TABLET
The invention relates to a press device for manufacturing compacted tablets from at least one mixture in powder form, comprising at least one compaction assembly comprising a lower punch (3) and an upper punch (4) each having an active compaction surface and placed on either side of a die, in which 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, characterised in that the central rod is coupled to the lower punch by means of 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.
Method and apparatus for contouring composite pre-preg articles
A forming tool and method for its use with flat pre-preg composite laminate assemblies which incorporates a mandrel segmented into multiple forming blocks, the forming blocks sized to receive a draped composite laminate assembly with all portions of the composite laminate assembly spaced from a shaping surface on each block. A spline plate engages the shaping surface of the forming blocks to provide a neutral axis for maintaining the entire composite laminate assembly in tension during forming. In the exemplary embodiments, the draped composite laminate assembly is formed to the forming blocks from the flat composite laminate assembly and maintained in contact with the forming blocks using a vacuum bag. The mandrel forming blocks arc then displaced to a desired curvature on the spline plate.
Profiling device, manufacturing method of display panel, and display panel
