Abstract:
The present subject matter relates to fabrication of micro-arc oxidation (MAO) based insert-molded components. In an example implementation, a method of fabricating a MAO based insert-molded component comprises forming an insert-molded component and oxidizing the insert-molded component through MAO. The insert-molded component has a metal body molded with a plastic body. On oxidation of the insert-molded component through MAO an oxide layer is formed on the metal body.
Abstract:
The invention relates to a method for producing a multi-section plastic component in which a first plastic injection-moulded individual part (10) and a second plastic injection-moulded individual part (20) are formed and said plastic injection-moulded individual parts (10, 20) are joined by injecting a plastic moulding compound. Said plastic moulding compound is a non-elastomeric thermoplastic and forms a plastic connecting component (30) following a curing process. Said plastic injection-moulded individual parts (10, 20) and plastic connecting component (30) are then at least partially painted. The invention also relates to a multi-section plastic component.
Abstract:
The invention relates to an injection-molding tool (2, 32, 72) for producing an injection-molded part (8, 38, 88), in particular from plastic, comprising an injection mold (4, 34, 74), which has a cavity (6, 36, 86) corresponding to the negative of the shape of the injection-molded part (8, 38, 88) to be produced, wherein a plasma nozzle (18, 52, 92, 130), which is designed to produce an atmospheric plasma jet (154), is connected to the injection mold (4, 34, 74) in such a way that, in the injection mold (4, 34, 74), a plasma jet (154) can be applied to an injection-molded part (8, 38, 88) produced in the injection mold (4, 34, 74). The invention further relates to a method for producing an injection-molded part (8, 38, 88) by means of an injection-molding tool (2, 32, 72), wherein the injection-molding material, in particular a plastic, is introduced into a cavity (6, 36, 86) of the injection mold (4, 34, 74) such that an injection-molded part (8, 38, 88) is formed, and wherein an atmospheric plasma jet (154) is applied to the injection-molded part (8, 38, 88) in the injection mold (4, 34, 74).
Abstract:
A fluid receiver fitting (FRF) for supporting aseptic fluid transfer between enclosures, as well as methods for forming the fluid receiver, is disclosed. The FRF includes a unitized seal section (226) and channel section (228) formed together by 2-shot injection molding, thereby eliminating or minimizing modes of fluid contamination where the seal section and channel section are separate members. The channel section may comprise one or more channels (286) for insertion of a needle (N) therein and a respective penetration zone (266) in a corresponding section of the seal section for the needle to penetrate and thereby extract a fluid sample from a liquid stream against which a portion of the seal section is exposed. An angled interface (288) between each channel and its corresponding penetration zone provides a liquid stream pressure concentration zone which applies pressure to close a core (C) in the seal section formed by removal of the needle.
Abstract:
Die Erfindung betrifft ein Verfahren zum Ausformen und Füllen von Kunststoffbehältern, wobei ein Vorformling (3) in einem Ofen erwärmt und in einer Hohlform zu dem Kunststoffbehälter ausgeformt und dieser Hohlform befüllt wird. Auf das Mundstück des Vorformlings wird vor dem Ausformen ein Verschluss (22) aufgebracht.
Abstract:
To produce a component (1, 8, 11) having a structured surface and a coating (3), firstly a composite body (2, 4) is produced, at least one first part (2) of the composite body (2, 4) having adhesion-promoting properties and at least one second part (4) having non-adhesive properties for a coating material (7), and then each first part and each second part (2, 4) of the surface is coated at least partially with the coating material (7) by means of plasma coating, the coating material (7) bonding in a firmly adhering manner exclusively to each first part. Finally, the coating material (7) is removed from each second part. The invention also relates to a component which can be produced by said method.
Abstract:
Die Erfindung offenbart einen Vorformling (20) mit einem Körper (22), der eine innere Wandung (22i) und eine äußere Wandung (22a) definiert, und mit einer Mündung (26). Der Körper (22) besitzt eine Wandstärke (22v). Der Vorformling (20) ist mit einem Mittel (30) versehen, das ein Siegel (38) umfasst, das eine Wandstärke (38d) besitzt, die kleiner als die Wandstärke (22v) des Vorformlings (20) ist, so dass mindestens in einem Innenraum (25) des Vorformlings (20) sterile Bedingungen während der Handhabung des Vorformlings (20) aufrecht erhalten bleiben. Das Siegel (38) ist derart ausgebildet, dass es zumindest teilweise plastisch und/oder elastisch deformierbar oder brechbar ist. Die Vorformlinge (20) können zumindest mit den sterilen Bedingungen des Innenraums (25) des Vorformlings (20) von einem Erwärmungsschritt (64) an ein Blasrad (3) übergeben werden. Die Erfindung offenbart auch ein Verfahren zum Handhaben und Verarbeiten von Vorformlingen.
Abstract:
Disclosed is a case including an injection preform (210, 310, 410) having a recess (111a) on at least one portion of a surface thereof, a deposition layer (120) deposited on a surface of the injection preform, and a paint layer (130) formed on the deposition layer. The deposition layer may directly contact a surface of the injection preform. A method of manufacturing a case includes injection-molding an injection preform having a recess on a surface thereof, forming a deposition layer directly contacting a suface of the injection preform, and forming a paint layer on the deposition layer.
