A process for producing a composite molded article is described. The composite molded article includes: (i) at least one base body ( ) having a contoured surface; (ii) at least one first thermoplastic part ( ); and (iii) at least one second thermoplastic part ( ), each of the first and second thermoplastic parts being joined to the base body. The process includes, (a) providing a multicomponent injection molding tool ( ) having at least two separate melt flow-way systems and at least two cavities in which each of the first and second thermoplastic parts are separately formed, each of the cavities are in separate communication with each of the separate melt flow-way systems. The base body is placed into the molding tool in a second step (b). The cavities of the mold are separated from each other by a combination of the contoured surface of the base body and sealing edges of the molding tool that abut the contoured surface of the base body. In a third step (c), a thermoplastic material is injected simultaneously into each of the cavities by means of the separate melt flow-way systems. The first and second thermoplastic parts (ii) and (iii) each become joined to the base body (i) during injection molding step (c). In a final step (d), the composite molded article is removed from the molding tool.

Process for preparing composite molded articles by multicomponent injection molding

The invention relates to a device for the continuous production of plastics/metal composite panels, in particular those having hollow chambered sections, from thermoplastic polymers ( ) and continuous metal sheets ( ), consisting of at least one plastics melting control system ( ), calibrators ( ), feeds for the metal sheets ( ) and a draw-off unit ( ), with the feeds for the metal sheets ( ) being arranged respectively above and below the melting control system ( ) and the calibrators ( ) being immediately adjacent to the feeds ( ) and the melting control system ( ).

A hollow-chamber lightweight component is described which at least comprises a shell-shaped housing part ( ) made of high-strength material. a ribbed supporting structure ( ) made of plastic, in particular of thermoplastic material, and at least one cover plate ( ) or covering shell ( ) made of a high-strength material which is, in particular. different from plastic and a method of producing the lightweight component is described. The supporting structure ( ) is up against the inside of the housing part ( ) and is joined, in particular. to the housing part ( ). The cover plate ( ) or covering shell ( ) largely covers the space formed from housing part ( ) and supporting structure ( ) and is joined in its peripheral region at least with one part of the boundary ( ) of the housing part ( ).

The present invention relates to dismountable vehicle panelling, and in particular a system for connecting vehicle body parts and panelling sections which are used as panelling for load-bearing supporting structures of vehicles.

The invention relates to polyamide molding compounds with increased viscosity, high thermal stability and favorable mechanical properties, to a process for their production and to their use.

Polyamide compounds containing diepoxide and having high viscosity

The manufacture of lightweight components having high strength properties can be improved in that a bowl-shaped shell (1) has reinforcing ribs (3) made from injected-on plastic in its interior (2) which are connected to the shell (1) at discrete connecting points (11) via perforations (12) in the shell (1), through which the plastic passes, extending beyond the surfaces of the perforations (12).

A vehicle door consists of a base, a cover facing the passenger compartment and an outside door leaf joined to the base and cover. Connection of the outside door leaf to the base and cover is arranged to provide easy removal and replacement of the door leaf. The door leaf has peripheral edges releasably connected to the base and cover. Moreover, at least one pair of corresponding edges in the cover and door leaf comprise grooves located in the plane of the door and opening toward one another. A joining and sealing resilient profile strip is positioned in the grooves to compensate for differences in thermal expansion.
