The invention relates to a device for producing three-dimensional models in a continuous process, comprising a build surface which has a first end in the direction of movement and a second end in the direction of movement, at least one dosing device and at least one solidification unit, characterized in that the build surface is designed to transport heavy components, and the components are transportable over the build surface essentially without distortion, and also comprising a method therefor.

A method for producing a semi-finished honeycomb-core product for producing a sandwich component, a method for producing a sandwich component, a semi-finished honeycomb-core product, a sandwich component, and the use thereof as a component of a motor vehicle.

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, additional methods for producing closures, and resulting closures are also provided.

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.

There is provided a method for producing a porous polyimide film, including a first step of forming a coating film containing a polyimide precursor solution where a polyimide precursor and an organic amine compound are dissolved in an aqueous solvent, and a resin particle incapable of dissolving in the polyimide precursor solution, followed by drying of the coating film to form a coat containing the polyimide precursor and the resin particle, and a second step of heating the coat to imidize the polyimide precursor and form a polyimide film, the second step including a treatment for removing the resin particle.

A method for soil remediation by molecular binding for producing beneficial use determined polymer concrete product that removes hazardous pollutants from a quantity of contaminated soil. Hazardous pollutants are identified though chemical analysis in order to select at least corresponding polymer and at least one corresponding binder for each hazardous pollutant present in the contaminated soil. The at least one polymer chemically bonds with the hazardous pollutant in order to neutralize the hazardous pollutant within the contaminated soil to form a polymer concrete product. The polymer concrete product is then used as a concrete substitute for construction applications.

A moulding tool for powder injection moulding a cemented carbide or cermet component includes a through hole. The mouulding tool further includes at least a first and a second tool part arranged to define at least one mould cavity for forming a component. At least one inlet channel introduces moulding material into the mould cavity. The inlet channel extends through the first tool part to the mould cavity, and has an outlet end having an outlet opening for discharging moulding material from the inlet channel into the mould cavity. At least one core forms a through hole in the component, the core having an end and being arranged to extend into the mould cavity along a longitudinal axis (X) in a direction towards the outlet opening of the inlet channel. The end of the core is arranged to close the outlet opening of the inlet channel and the core is arranged movably along the longitudinal axis (X) such that the end of the core may engage with the outlet opening of the inlet channel.

A method of manufacturing a hollow core door is disclosed, as wall as a corresponding hollow core door. The method includes the steps of providing a solid flat door skin, moisturizing the flat skin, applying a conditioning resin thereto, pre-heating the flat door skin, and thereafter pressing the flat door skin between a pair of heated platens in a press in order to reform the flat skin into a molded skin including a plurality of panels defined therein. The press continuously closes in order to reform the flat skin into the molded skin, with the rate of press closure being a function of the determined hardness of the flat skin to be reformed. The resulting door skins have an improved bond strength, and are efficiently manufactured.
