The present invention relates to a polyester sound absorption material having improved moldability and decreased weight and a method of manufacturing a molded product using the same, and more particularly to a polyester sound absorption material, which is capable of integrally molding a skin member and a sound absorption material using a felt including a polyester base fiber, a low-melting-point polyester adhesive fiber and a polyester hollow fiber, without the need to attach an additional sound absorption pad onto a skin member.

The present disclosure relates to a method for manufacturing a seat padding comprising:/A/ providing a padding comprising a 3D entanglement of continuous thermoplastic fibers arranged irregularly forming loops welded together, the padding having a length direction, a width direction, and a thickness direction, as well as a border on the periphery extending along the edges of the padding/B/ Hot pressing of the 3D entanglement of fibers, at all or part of the periphery of the padding, so as to produce a densified and stiffened border of the padding, relative to a central zone of the padding of less density and of less rigidity. The present disclosure also relates to padding as such, as well as to a vehicle seat comprising such padding.

The disclosure relates to a fiber material for producing a container, wherein the fiber material comprises fiber structures for ensuring a predetermined stability of a container produced from the fiber material. Furthermore, the disclosure relates to a method for producing a container using the fiber material, and container comprising the fiber material.

A filling unit for filling cavities in a tablet press with a feedstock to be pressed, particularly a powder, having a filling assembly including a fill chamber. The fill chamber is arranged in the installed condition between a die table containing the cavities and a punch support including at least one punch. The fill chamber has at least one inlet opening for filling the fill chamber with raw material and at least one outlet opening for filling the cavities of the tablet press with feedstock to be pressed. The filling chamber has at least one mixer for mixing the raw materials of the feedstock to be pressed arranged at least partially in the fill chamber and at least one delivery unit for filling the cavities of the tablet press with feedstock to be pressed.

A compression-molding apparatus includes a sleeve plunger and a core pin. The sleeve plunger is movable through a plunger cavity that, in some embodiments, extends through the male portion of the molding apparatus. The sleeve plunger has a bore, and is received by and movable along the core pin, which typically extends upward into the plunger cavity from the female portion of the molding apparatus. In addition to any other functionality, the core pin forms a hole in a molded part. In operation, the fiber-bundle-based-preform feed constituents are placed in the plunger cavity. If any of the preforms are ring-shaped preforms, they are received by the core pin.

A powder application apparatus for an at least partially meltable powder to be applied onto a feeding element for producing reinforcing elements comprises a powder container. In the area of an outlet of the powder container a template for defining a basic shape of a reinforcing element to be produced is provided. Further, a closing device for opening and closing the outlet is provided. For producing reinforcing elements having different stiffness, barrier elements in particular connected with the template are provided. The barrier elements reduce the powder supply to the feeding element such that a reinforcing element with areas of different material thickness are created. A method for producing such a reinforcing element.

A polar plate is fabricated. The polar plate is flexible and made of a plastic graphite composite. No matter a supporting member is used for calendering or not, a thin polar plate with controllable thickness is fabricated. The polar plate is excellent in blocking the through-transmission of vanadium ions and the limit of blending ratio of conductive carbon is broken through. The longitudinal through-transmission volume resistivity (proportional resistance to thickness) is greatly improved by adjusting the blending ratio of conductive carbon for meeting the demand of conductivity. In the mean time, the present invention strengthens the rigidity required for the thin polar plate while providing large-area polar plate fabrication for industrial use and convenience and provides a cooling and pressing method for patterning a composite polar plate. An integrated mold is thus obtained to replace the conventional polar plate which needs to be processed and prepared with runner.

The method of recycling carbon fiber prepreg waste and transparent thermoplastic waste includes shredding of a volume of transparent thermoplastic waste and a volume of carbon fiber prepreg waste, where the carbon fiber prepreg waste includes a colored backing film. The colored backing film may have a plurality of colors associated therewith, yielding a mixture of multi-colored shreds. A mold is filled with the shredded volume of transparent thermoplastic waste, and the mold is inserted and compressed in a hot press. The shredded volume of transparent thermoplastic waste is cured in the hot press to produce a transparent sheet. The shredded volume of carbon fiber prepreg waste is then heated, such as, for example, with hot air, and then spread on the transparent sheet. The heated, shredded volume of carbon fiber prepreg waste and the transparent sheet are hot pressed to form a colored sheet with a transparent protective layer.
