The disclosure relates to a method for producing an optical element (42, 43) having at least one optically effective surface, wherein, by means of a first injection mold of an injection-molding machine (500, 500′) liquid transparent plastic (54, P4014, P4017) is injection-molded to form a preform and/or a pre-molded part (20) having at least one preform (22, 23), the preform or the pre-molded part (20) subsequently being cooled outside the first injection mold and/or outside the injection-molding machine (500, 500′), and the preform (22, 23) to form the optical element subsequently being injection-molded and/or over-molded in a second injection mold by applying at least one layer of plastic, which forms the optically effective surface (42, 43).

An injection-molded component having a casing body of plastics material and a core which is made of a core material, in particular of a metal, which is at least partially received within the casing body and is at least partially insert-molded. The injection-molded component may in particular serve as a joint part of a joint. As a result of the preferably metallic core, the injection-molded component, despite comparatively small dimensioning, is capable of being comparatively highly stressed. By virtue of the casing body of plastics material, a minor actuation noise may be implemented for the joint, even without complex lubrication.

A new type of RFID tag is provided. A gaming chip that incorporates a sticker-type RFID tag comprises: an enclosing member having a predetermined shape for enclosing the RFID tag; a body member that is injection-molded to encapsulate the enclosing member with the RFID tag; and a gaming chip for amusement. The enclosing member consists of a first part and a second part, and at least the first part or the second part has a flat surface to which a sticker-type RFID tag can adhere, and the first part and the second part are combined to form an enclosing member, in which the sticker-type RFID tag is covered by the first part and the second part.

A molding die includes a first mold assembly, a second mold assembly, and a mold core. The first and second mold assemblies are adapted to be clamped together. The mold core defines a molding groove. The molding core is pressed between the first and second mold assemblies to form a molding cavity. The second mold assembly includes a light transmitting area corresponding to the molding cavity, so that the molding cavity will receive incident light through the light transmitting area. In the molding die, the first mold assembly, the second mold assembly, and the mold core cooperate to form the molding cavity, adhesive is injected into the molding cavity, and the molding cavity receives incident light through the light transmitting area, so that curing efficiency of the adhesive is improved, production efficiency is high, shape of molded adhesive is uniform, and product quality is improved.

A solar heat exchanger for heating water which includes an array of tubes, an injection molded manifold there being connections between each tube in the array and the manifold which are over molded to seal the tubes to the manifold.

A method for manufacturing a heatable plastic component for a motor vehicle, which includes: providing a planar heating film, which has a first surface and a second surface that faces away from and is opposite the first surface, including at least one heating wire and connecting elements; introducing the planar heating film into an injection mold; mounting a connector housing onto the connecting elements; and back-molding the first surface with a plastic for manufacturing a first partial element of the heatable plastic component in the injection mold. In order to provide an improved method for manufacturing a heatable plastic component, it is proposed that a back-molding of the second surface with a plastic for manufacturing a second partial element of the heatable plastic component in the injection mold takes place such that a composite is formed from the first partial element, the planar heating film and the second partial element.

Disclosed herein are contraceptive medical devices that include at least a polymeric ring, a porous barrier material and an injection molding guide, where the guide may be symmetrical and/or have one or a plurality of planar surfaces, where the device may optionally administer at least one active agent.

A fiber preform is provided for use in an overmolding process that includes a fiber bundle arranged in a predetermined pattern and attached to itself by a plurality of stitches of a thread to form at least one preform layer. At least one positioning element is associated with the at least one preform layer, the at least one positioning element configured to engage with at least one corresponding alignment element on a mold to indicate proper positioning of the fiber preform within the mold. A process of overmolding is also provided in which the at least one positioning element of the fiber preform engages with the at least one corresponding alignment element on the mold to indicate proper positioning. The mold cavity is then filled with a resin to permeate the fiber preform engaging the mold in a unique orientation to yield an article upon resin cure.

An injection molding method for a product with a connection elastic sheet, a loudspeaker and an electronic device are provided. The method comprises: providing a blank material comprising at least one connection piece and a material connection strip, and each connection piece comprising an elastic arm portion and a wire portion; positioning the blank material as an insert in a first injection mold by means of the material connection strip; injecting a first injection plastic part into the first injection cavity to obtain a first injection product; processing the first injection product for bending up the elastic arm portion toward an outer surface of the first injection plastic part; placing the processed first injection product into a second injection cavity of a second injection mold, and sealing the elastic arm portion; and injecting a second injection plastic part into the second injection cavity.

A method of manufacturing a composite component according to various aspects of the present disclosure includes disposing a fiber preform in a mold. The fiber preform includes a first portion having a first edge and a second portion having a second edge. The first edge and the second edge cooperate to at least partially define a gap.
