摘要： The application relates to a method for the additive manufacture of a product, wherein a melt is discharged via a 3D printing head and the melt is deposited in the form of a melt strand on a printing table to form the product, wherein the 3D printing head and/or the printing table are moved in space in accordance with a product-specific computer program. The application is characterised in that the melt is supplied to the 3D printing nozzle via a needle valve nozzle. For the additive manufacture of the product, a volumetric flow of melt is specified which is specified by the geometry of the melt strand to be deposited and the traverse rate of the 3D printing nozzle and/or the printing table. The nozzle needle is moved between the closed position and the open position in such a way that the specified volumetric flow is maintained during the additive manufacture of the product.

摘要： The invention relates to a method for producing molded parts, wherein semifinished product is heated in a heating device and is subsequently fed to a shaping machine. The heating device has a closed housing having a door or has a separately closable opening. The heating device optionally has a dividable housing, in the case of which the housing components can be moved away from each other in order to form an opening and can be moved toward each other in order to form a closed housing. One or more radiant heaters, in particular infrared radiant heaters, are provided in the interior of the housing. Semifinished product is introduced into the interior of the housing and radiant heat produced by the radiant heaters is applied thereto, said semifinished product is heated, and said semifinished product is subsequently removed from the housing. Thermal convection, which is directed substantially upward in the housing, is produced in the interior of the housing. According to the invention, an air flow counteracting the thermal convention, in particular an air flow directed substantially downward in the interior of the housing, is produced in the interior of the housing.

摘要： A method is described for producing fibre-reinforced plastic moulded parts, wherein endless fibre strands are fed by a fibre braking device and/or cut fibres via a gravimetric metering device, and a plastic material to be melted, by a volumetric metering device are fed to a single-screw plasticizing unit. Plastic material which is molten and is mixed with fibre material is injected into a moulding tool by an injection stroke of the plasticizing screw. According to the application, the ACTUAL mass flow of the plastic material is calculated from the ACTUAL volume flow of the plastic material and from the ACTUAL mass flow of the fibre material. The ACTUAL mass flow of the plastic material is compared to a TARGET mass flow of the plastic material, and the rotation speed nd of the rotary drive of the metering element of the metering device is adapted.

摘要： A plasticizing unit is provided for an injection unit of an injection moulding machine with a support element arranged beneath the cylinder and connected therewith. To simplify adjusting of the nozzle centre, a fixing element surrounds the end of the support element facing away from the cylinder such that a distance is present between the fixing element and the support element. Several adjusting elements are provided, to produce a force-fitting and/or form-fitting connection between the fixing element and the support element to adjust the position of the support element relative to the fixing element in a plane orthogonally to the cylinder axis. The plasticizing unit can be clamped in and out with its fixing element in a clamping- and positioning system connected with the machine bed. On changeover of the plasticizing unit, an adjusting of the nozzle centre, which has been carried out once, is retained.

摘要： A fin block is provided for a calibrating device for the calibrating of an extruded plastic profile, wherein the fin block includes a back structure and a fin structure having a plurality of fins. The fins are spaced apart from one another and arranged on the back structure in longitudinal direction (L) of the back structure. The back structure of the fin block has a plurality of apertures, the shape and/or arrangement of which within the back structure depends on a predetermined mechanical load capacity for the back structure. Furthermore, a method for the production of the above-mentioned fin block and a calibrating device, which includes a plurality of the above-mentioned fin blocks, is provided. Furthermore, a system for the additive manufacture of the above-mentioned fin block, a corresponding computer program and a corresponding data set is provided.

摘要： A method and a device for producing fibre-reinforced plastic mouldings, using coated fibre strands. For the coating of the fibre strands, an air flow of ionised air is produced and guided through a Venturi nozzle. Powder from a storage container is taken by means of a screw conveyor and supplied to the Venturi nozzle, a flow of a powder-air mixture being present or forming behind the Venturi nozzle in the direction of flow. This stream is introduced into a chamber and fibre strands that are earthed or ionised unlike the powder are passed through the chamber and through the powder-air mixture flowing through the chamber, powder particles being deposited on the fibre strands. The fibre strands guided out of the chamber therefore have a coating, and the fibre strands coated in this way are supplied to a plasticising device of an injection moulding machine or an extrusion machine.
