A mold assembly for producing a part includes a first section, a second section movably coupled to the first section, and a cavity defined by the first section and the second section, the cavity being shaped to receive a part while the first section and the second section are movably coupled to each other. The mold assembly includes a joint formed by adjacent surfaces of the first section and the second section and a seal extending along the joint.

The present invention relates to a mold for molding a component, in particular a particle foam part and a method for manufacturing the component using such a mold. In one embodiment, a mold for molding a component comprises (a.) a mixture of a polymer material and a filler material, (b.) wherein the filler material is adapted to allow a heating of the component inside the mold by means of an electromagnetic field.

This specification relates to a decoration member including: a substrate; a pattern layer comprising two or more unit pattern provided on one surface of the substrate; and an inorganic layer formed on the pattern layer, in which the inorganic layer includes a region in which a thickness t(x) of the inorganic layer formed on each unit pattern increases in a direction x in which the unit patterns are arranged.

The present disclosure relates to a decoration member comprising: a color expression layer comprising a light reflection layer and a light absorption layer provided on the light reflection layer; and a substrate provided on one surface of the color expression layer, in which the light absorption layer comprises a copper nickel oxide (Cu.sub.aNi.sub.bO.sub.x).

Provided is a method for manufacturing a fiber reinforced plastic molded body, the method including: performing thermocompression molding, by using a molding die, on a molding precursor which is obtained by arranging a prepreg including a thermosetting resin and a fiber around a thermoplastic solid body.

Systems and methods for casting solid propellants include a mandrel for forming geometric features in a perforation of a propellant grain. In various embodiments, the mandrel includes a frangible portion that is removed from the propellant grain after the propellant grain has cured around the mandrel. A second portion of the mandrel may be left behind in the propellant grain. The mandrel may include a support structured disposed in the through hole of the mandrel. The support structure may include a plurality of longitudinal channels for directed exhaust gasses through the mandrel upon ignition of the propellant grain.

Tubular polymeric structures are formed by creating a convex mold conforming to a fluid pathway design, depositing a coating of polymer over the mold, and in situ removing the mold without drawing it against the polymer. The resulting structures are fabricated with flow-altering features.
