Abstract: Resin supply system in which resin material is stored in a pouch in a degassed state ready for use. The pouch comprises a body portion forming a reservoir for resin material and a connector portion in fluid communication therewith. The connector portion includes an outlet which is configured to be connected to an injector head of an injector assembly, the injector head being connectable to a mould by means of connecting tubing to provide a resin supply thereto. The pouch is configured to be mountable in a housing of the injector assembly and is compressed by hydrostatic pressure of water surrounding the pouch in a chamber of the housing. The application of pressure by a piston moving in a direction transfers pressure to the water and then to the pouch in a controlled manner to provide the resin supply to the mould. After use, the pouch is removed and discarded thereby substantially eliminating the need for cleaning of the housing after use.

Abstract: A plasticizing device includes a plasticizing mechanism including a feeding port for receiving a material and configured to plasticize the material to generate a melted material and a material feeding mechanism configured to feed the material to the plasticizing mechanism. The material feeding mechanism includes a housing including a depositing port communicating with the feeding port, the housing storing the material, and a rotating member housed in the housing and capable of rotating along an inner edge of the housing. A plurality of through-holes are provided in the rotating member at intervals along an outer circumference of the rotating member. When the rotating member rotates and any one of the plurality of through-holes and the depositing port communicate, the material stored in the housing is fed from the feeding port to the plasticizing mechanism through the depositing port.

Abstract: The invention relates to a method for producing a three-dimensional object (50) by means of generative construction in a direct constructional sequence from at least one solidifiable material. At least one material component is discharged in a programmable way via a control device in the direct constructional sequence and, as a result of the discharge, produces structurally different regions of the object (50) that are joined together, wherein geometric relationships obtained during the discharge already correspond to the object (50). The fact that configuration criteria for the structurally different regions of the object (50) are predefined to the control device by using a selection, and that the discharge unit is controlled by the control device during the discharge of the at least one material component for the structurally different regions of the object by using the selected configuration criteria in order to configure a three-dimensional structure desired for the respective region of the object, means that a method is provided by means of which the discharge of the material can be carried out in accordance with individual requirements on the object.

Abstract: A fire retardant molding contains a thermoplastic compound and an inorganic flameproof agent that is mixed with the thermoplastic compound and which acts by separating from water, having a proportion in the range of 10 wt % to 90 wt %. The fire retardant molding is produced by mixing the thermoplastic material with an inorganic flame-proofing agent, the flame-proofing agent having a proportion in the range of 20 wt % to 80 wt %, and by outputting the compound obtained by mixing, in particular as a flat product. The fire retardant molding is advantageously used, for example, in or on land-based vehicles, water-based vehicles, aircraft and buildings.
