A composition for making a molded article such as a reel flange, and a method making the same, are provided. The composition may consist essentially of about 75-95 wt % dry waste wood and about 10-25 wt % binder such as melamine-urea-formaldehyde (MUF) or PMUF resin. The waste wood may be recycled wood fiber from pine or other hardwoods, sawdust and wood chips. The method comprises mixing dry waste wood with MUF or PMUF resin binder to make a wood/resin mixture, and compressing the wood/resin mixture in a mold cavity at a pressure and temperature.

A method for manufacturing a closure constructed for being inserted and securely retained in a portal-forming neck of a product-retaining container is provided. Such method may include intimately combining a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymers, optionally in combination with other constituent(s) to form a composition, heating the composition to form a melt, extruding or molding a closure precursor from the melt to provide a specified water content range, and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure for a product-retaining container includes a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymer, optionally in combination with other constituent(s). Methods for producing particulate material, cork composite material, and additional methods for producing closures are also provided.

A method for manufacturing an impregnated fibrous material comprising at least one fibrous material made of continuous fibres and at least one thermoplastic polymer matrix comprises a step of pre-impregnating the fibrous material with a thermoplastic polymer matrix in powder form. This step is carried out dry in a tank comprising a fluidized bed, while keeping the level h of the powder and the mass m of the powder present in the tank substantially constant. The level h is from hi to hi−3%, during implementation of the pre-impregnation step, and hi is the initial level of the powder in the tank at the start of implementation of the pre-impregnation step, the mass m is from mi to mi±0.5% during implementation of the pre-impregnation step, and mi is the initial mass of the powder in the tank at the start of implementation of the pre-impregnation step.

The present invention provides methods for preparing the nut waste pot composites from a nut waste component, one or more binders, and an oil using a compounder/extruder.

A three-dimensional printer device includes a supplying apparatus, a formation table, a recycling trough, a distribution apparatus, a power collection cover, and a control unit. The supplying apparatus is provided to contain the powder material. The formation table has a horizontal surface, and one side of the horizontal surface is disposed adjacent to the supplying apparatus. The recycling trough has an opening, the opening is disposed at the other side of the horizontal surface opposite to the supplying apparatus. The distribution apparatus includes a roller; the roller is movable across the horizontal surface between the supplying apparatus and the recycling trough, so that the powder material inside the supplying apparatus can be distributed onto the horizontal surface. The powder collection cover covers the roller. The control unit is electrically connected to the distribution apparatus and controls the roller to move between the supplying apparatus and the recycling trough.

A method for producing a composite part. The method includes the following steps: stacking a first mat, a spacer and a second mat in a heatable mold; at least one of the mats including a continuous web of fibers impregnated with a thermosetting resin; and compressing and heating of the stack by the heatable mold, in order to polymerize the thermosetting resin. The stacking step includes the deposition, in a heatable mold, of a first and a second filtration layer, in contact respectively with the first and second mats, on the opposite side from the spacer. The filtration layers are porous to steam and relatively less porous to the thermosetting resin. During the compression and heating step steam is evacuated from the mold.

The present invention describes a method for building modes in layers, wherein a first material and subsequent thereto selectively a second material are applied in layers in a build space, and these two application steps are repeated until a desired model is obtained. The two materials form a solid object in a suitable mixing ratio, the first material including a particulate material and the second material being applied with the aid of a print head. The first material, the second material and/or the particulate material include one or more diamines and/or one or more dicarbonyl compounds as tree binder.

A honeycomb structure (110) includes intersecting porous walls (106). Inlet channels (108i) and outlet channels (108o) are formed by the intersecting porous walls (106), wherein the inlet channels (108i) comprise inlet hydraulic diameters (HDi) and the outlet channels (108o) comprise outlet hydraulic diameters (HDo). The inlet channels (108i) comprise inlet corners (220i) with inlet corner radii (Ri) and the outlet channels (108o) comprise outlet corners (2200) with outlet corner radii (Ro). A centerpost (124) is defined by adjacent opposing inlet corners (220i) of two of the inlet channels (108i) and adjacent opposing outlet corners (2200) of two of the outlet channels (108o). A first diagonal length (D1) is a shortest distance between the opposing outlet corners (220o) of the two outlet channels (108o) and a second diagonal length (D2) is a shortest distance between the opposing inlet corners (220i) of the two inlet channels (108i). The honeycomb structure (110) has certain aspect ratios D1:D2 depending on hydraulic diameter ratios HDi:HDo.
