摘要： Forming systems and assemblies as disclosed herein comprise a composite material comprising a structural component and a resin component combined with the reinforcing component. A forming element is disposed within the composite material and has a coefficient of thermal expansion that is greater than that of the composite material. The forming element is positioned to provide a desired integral structural reinforcement and/or surface feature to the composite. The composite material may comprise one or more passages extending from a surface thereof to the forming element. The composite material may be cured by heat to take a set configuration and then allowed to cool. The cooling of the composite material and the forming element enables the forming element to contract relative to the composite material and become delaminated therefrom to facilitate easy removal, and thereby provide an improved method and assembly for making structural reinforcing features in composite structures.

摘要： The injection mold has a mold core including a first part and a second part. The parts are mobile relative to one another between a first injection position in which they are moved together to form an injection cavity permitting the injection of a material to form an injected part (50; 50′), and a second demolding position in which they are moved away from one another to permit the demolding of the injected part (50; 50′). The injection mold has at least one ejector designed to contribute to the demolding, and at least one movable intermediate plate (10; 10′, 20′), separate from the two parts of the mold core. The intermediate pate is arranged between the two parts of the mold core, and has at least one cutout (12; 12′, 22′) forming at least one part of the injection cavity of the injection mold.

摘要： The invention relates to a method for producing a hollow injection-moulded part, in particular a primary packaging means for medical applications by an injection moulding method, comprising the following method steps:
a) Providing a first female die tool having a first mould cavity and a mould core formed as a male die tool;
b) Introducing a mould core into the first mould cavity so that a first cavity is formed and the mould core extends beyond the mould cavity in the axial direction (X), thereby bringing the mould core into operative contact with the first female die tool and/or with a receiving member;
c) Injecting a first plastic material into the first cavity so that a first portion of the injection-moulded part is formed;
d) Transferring the first portion of the injection-moulded part to a second cavity;
e) Injecting a second plastic material into the second cavity so that a second portion is formed directly on the first portion of the injection-moulded part.-

摘要： A mandrel configured to facilitate release of an elastomeric part cured thereon may comprise an elongated body having an outer surface, an internal cavity formed in the elongated body, and a passage providing fluid communication between the internal cavity and the outer surface of the body. The passage may be dimensioned so as to permit a flow of a fluid from the internal cavity to the outer surface of the body and to preclude a flow of an uncured elastomer into the passage. The flow of the fluid from the internal cavity to the outer surface may cause the fluid to intervene between the outer surface of the mandrel and the elastomeric part to facilitate the release of the elastomeric part from the mandrel.

摘要： The present invention provides a die assembly for molding a resin-made insert having a sleeve that is inserted into an intake port of an internal combustion engine. Each sleeve has one inlet and two outlets. The die assembly includes an inner die and an outer die. The inner die includes an inlet side part and an outlet side part. The inlet side part and the outlet side part mold an inner peripheral surface of the sleeve in an assembled state, and are removed in mutually opposite directions. By means of this assembly, a sleeve having a complicated structure and shape can be molded easily.

摘要： An injection-molding press for overmolding a second part onto a first part (8) includes a movable portion and a fixed portion, with a first mold element (11, 12) on one of the press portions and a second mold element (20) on the other press portion so as to form a cavity (C) between the mold portions when the press is closed. The first mold portion (11, 12) has a first support surface (125a) movable in the first mold portion and the second mold portion (20) has a second support surface (22a). In the closed position of the press with a first part (8) in the first mold portion and the first support surface (125a) advanced in the working position, at least a portion (8b) of the front end of the first part (8) is clamped between the two support surfaces (125a, 22a), forming a tight seal for the cavity (C).
