The invention relates to a molding device (1) and a method for the manufacture of structured or semistructured composite components comprising a polymer resin (50) and a fibrous substrate (51). According to the invention, the device comprises a mold (2) comprising a bottom and a lateral surface, a part (10) that is movable along the lateral surface of the mold, comprising a compression surface (14) forming a cavity (7) with the bottom and the lateral surface (5) of said mold (2), characterized in that the movable part (10) comprises a vacuum-drawing channel (13, 23) opening into a chamber (25, 42) located above the cavity and communicating with said cavity (7).

The invention concerns in particular a device for moulding an article in which the article is obtained by compression moulding a dose (14) of material in the molten state and comprises at least one orifice (23) after the compression moulding operation, said device comprising at least one die (10), one mandrel (11) cooperating with said die (10) to effect the operation of compression moulding of the dose and one orifice rod (12) sliding in said die (10), said device further comprising a shape endpiece (13) placed between the mandrel (11) and the orifice rod (12) to form the orifice (23) of the article.

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.

Described herein are expandable foaming molds. The foaming molds described herein permit mold boundaries to expand along with the expanding polymer and thereby conform to the foaming dynamics of the polymer material. By modifying the temperature and pressure applied to the mold devices described herein, the properties of the resulting foamed polymer can be fine-tuned for specific applications.

The process immerses a plurality of smaller solids in a liquid softening/solvent/bonding agent (i.e. water, oils, solvent or some other combination). This reagent reacts with the solids over a period of time so that when the cavity containing the solid/liquid mixture is compressed, the solids and any other additives (i.e. oatmeal, spices, other foreign objects, etc . . . ) are forced together and force the liquid softening/solvent/bonding agent out. The expelled liquids are removed from the solids and additives which are then allowed to dry/bond/fuse thereby forming a solid bond. Whereas there is prior art utilizing aspects of this process specifically in soap scrap bonding, this method is the only method of compressing solids that does not require electricity and where the disparate solid pieces and the bonding agent/liquid are all contained in one vessel that enable the solids to react with the liquids and then be compressed removing the bonding agent/liquid and leaving only the solids which can then form a permanent bond, all in one device (see FIG. 8: Novel Mould Assembly , FIG. 10—Mould Assembly Option, FIG. 12—Novel Mould Assembly with Option Plunger Design). Furthermore, this design can incorporate the collection and if desired recycling of the reagent within the mould itself (i.e. a hollow cavity in the plunger and if necessary a collection vessel attached to the cap and/or stabilizing base). Finally, the plunger design allows the device to be used with or without any mechanical aids to prevent it from binding during longitudinal movement during compression of the mould/plunger. This, first of all, simplifies the mechanics of the device and allows the mould to be used by young and old alike regardless of ability.

This device will have applications in many industries but especially the craft industry (i.e. cheese making and soap making).

A seal system includes a male body and a female body that are slidable in relation to one another in an axial direction and between which an interstice is arranged. Plastics in pasty state pass through the interstice to a chamber partially defined by at least one of the aforementioned bodies. An elastic strip is arranged in the interstice to prevent leakage of the plastics.

The foaming molds described herein permit mold boundaries to expand along with the expanding polymer and thereby conform to the foaming dynamics of the polymer material. By modifying the temperature and pressure applied to the mold devices described herein, the properties of the resulting foamed polymer can be fine-tuned for specific applications.

A cap comprises a cap body including a top plate portion and a skirt portion integrally provided with the top plate portion through a corner portion and screwed to a mouth portion of a can container, and a disk-shaped sealing member including a sliding layer which is provided separately from the cap body to face the top plate portion, includes a protrusion portion formed on an outer peripheral side of a portion opposed to the mouth portion when the cap body is screwed with the can container and gradually decreasing in thickness toward an outer peripheral edge, and slides on the top plate portion and a sealing layer which is integrally provided with the sliding layer and seals the mouth portion.

A plastic sintered body has a first compressed portion formed by heating plastic powder packed in a cavity of a metal mold and sintering a first portion of the plastic powder packed in the cavity in a first compression state. In addition, a second compressed portion is formed by sintering a second portion of the plastic powder packed in the cavity in a second compression state. A plurality of interconnected minute voids are formed in the first compressed portion and a plurality of interconnected minute voids smaller than the voids in the first compressed portion are formed in the second compressed portion. The manufacturing of the plastic sintered body as noted above is performed continuously in the metal mold. In addition, two types of porous portions including voids of different sizes are formed by sintering only one type of the plastic powder in the metal mold.
