Apparatus and method for laminating a film part on a carrier part, method for laminating a carrier part with a film part, method for retrofitting a tool as well as installation for producing a component laminated with a film layer
The invention relates to an apparatus for laminating a film part, in particular a decorative layer, on a carrier part having a laminating region in which the film part can be laminated onto the carrier part, in particular onto a motor vehicle interior trim part, having an edge region arranged adjacent to this laminating region in which the film part projects beyond the carrier part in order to produce a bend-around region on the film part which can subsequently be bent around a carrier part edge, and having a tool in which the tool comprises a first tool half for producing a surface design on the film part and a second tool half for receiving the carrier part, wherein the first tool half comprises thermally differently acting sub-regions, namely a first sub-region with a contour for the surface design which interacts with the laminating region and a thermal sub-region which interacts with the edge region adjacent to the laminating region.

Method Of And Apparatus For Manufacturing A Plastic Container Having A Curled Rim
A method of manufacturing a plastic container having a curled rim (320) comprises the steps of providing a sheet of plastic material; drawing a portion thereof into a mould (120) to form a bottom and wall (310′) of the container, leaving a surrounding portion of material to form a rim (320) of the container; cutting the rim loose from a remaining portion of material; and curling the rim. In the curling step, an inner part of the rim is supported by a supporting member while an outer part is pressed by a pressing member (230) moving relative to the supporting member for the rim to be bent around the supporting member.
Method for recycling plastic materials
The invention relates to a method and to an assembly for recycling plastic materials, comprising the following processing steps: a) reprocessing the raw material, wherein the material, if necessary, is comminuted and brought into a fluid-like form and heated and permanently mixed, while preserving the lumpiness and pourability thereof, and optionally the viscosity thereof is increased and/or it is degassed, softened, dried and/or crystallized; b) melting the reprocessed material, at least so much that filtration is possible; c) filtering the melt in order to remove impurities; d) homogenizing the filtered melt; e) degassing the homogenized melt; and f) discharging and/or subsequently processing the melt, such as by granulation, blown film processing, with said processing steps being carried out consecutively in the order listed.
Hybrid sustainable composites and methods of making and using thereof
Composites containing one or more synthetic plastics, such as thermoplastics, one or more natural materials, such as plant/tree fibers, and biochar and/or torrefied material are described herein. The composite can contain additional additives, such as reinforcing agents and/or fibers, compatibilizers, etc. The composites have improved mechanical and/or physical properties, such as strength, impact strength, rigidity/modulus, heat deflection temperature, moldability/melt flow index, renewability, and lower cost compared to composites that do not contain the biochar and/or torrefied material. The presence of the biochar and/or torrefied material also serves to remove the odor often associated with natural fibers and other additives.
System and method for improving the performance of a nanoimprint system
A system and method of imprinting a formable material on a substrate includes a feature with a template. The substrate is initially held with a first back pressure. After which the template is brought into contact with the formable material. A template strain tensor above the feature may be greater than a strain threshold. The substrate is then held with a second back pressure less than the first back pressure, after which the substrate strain below the feature increases. After which the formable material is solidified.
Method for producing hollow bodies from thermoplastic material and apparatus for carrying out the method
The invention relates to a method for producing hollow bodies from thermoplastic material and to an apparatus for carrying out the method. The method comprises the molding of at least two sheet-like preforms in web form of thermoplastic material into two complementary shells in a multi-part tool, which in a closed position forms a mold impression, and the joining together of the shells to form an essentially closed hollow body, the preforms being brought between the parts of the tool in an opened receiving position of the parts of the tool and the preforms being placed into the part-cavities by applying differential pressure and being at least partially molded in them into shells. The shells are joined together to form an essentially closed hollow body by closing the tool to form a closed mold impression. The method is distinguished by the fact that the preforms are molded in the part-cavities while the parts of the tool are located in the opened receiving position.
SYSTEMS AND METHODS FOR DEPOSITING COMPOUNDS IN A STRUCTURE
Presently disclosed systems and methods for depositing a compound into a void in a sandwich panel are configured to reduce the air pressure in and around the void as the compound flows into the void, thereby reducing the amount of air trapped between the compound and the sandwich panel skin within the void during the repair. Systems may include a dispenser for holding the compound, a vacuum canister, and a valve operable to allow the compound to flow from the dispenser, through at least a portion of the vacuum canister, and into the void. After the compound flows into the void, the system is configured to apply ambient air pressure to the compound and the void, before the compound is allowed to harden or cure. Some such systems are pre-filled with the compound, and/or configured to be disposable after a single use.
CONTAINER
A container, in particular in ampoule form, and consisting entirely or predominantly of plastic materials, having a container body (10) for receiving a filling product (12), which can be removed via a releasable container opening (22) after a closure part (18) has been removed, which is detachably connected to the neck part (14) of the container body (10) along a separation line (20) in an unopened position, is characterized in that, in the unopened position, a conically extending wall (36) on the neck part (14) on the container body (10) and a conically (38) or cylindrically extending wall (38a) on the closure part (18) adjoin the separation line (20), and that these walls (36, 38, 38a) delimit at least part of an annular space (40, 40a), one end of which opens out into the environment and the other end of which opens out into the separation line (20).
Method for producing at least one flexible plastic container
The invention relates to a method for the manufacture of at least one flexible plastic container, according to which method each container (10) comprises two separate walls (12, 13) facing one another joined at their circumference by a sealed peripheral edge (14), said separate walls defining a storage space of the container (10). According to the invention, at least the following stages are realized: a) Forming a pile of two sheets (26, 27) of plastic material, said sheets (26, 27) being laid one against the other, the surfaces which face one another of these sheets (26, 27) being placed directly in contact with one another without any element acting as an interface, b) Simultaneously shaping said sheets (26, 27) thus laid one against the other in order to define said at least one container (10) without having previously separated these sheets, at least each container (10) being partially formed, said sheets (26, 27) being maintained lying one against the other in at least one section of the areas of said sheets (26, 27) intended to constitute said peripheral edge (14) of each container (10) during this shaping and c) Sealing at least partially the areas of said sheets (26, 27) intended to constitute said peripheral edge (14) of at least each container (10).
