The present disclosure includes systems, devices, and methods for preventing contamination during formation of an optical article. In some implementations, a device for preventing contamination of a mold cavity during injection molding of a function wafer includes a containment band having an annular base that defines a first opening configured to receive a functional wafer. The device also includes one or more sidewalls that project a first direction from and surround at least a portion of the first opening. The one or more sidewalls may be configured such that, during formation of an optical article, a first portion of the functional wafer is in contact with the one or more sidewalls.

An electronic medical device is disclosed here. An exemplary embodiment of the medical device includes a printed circuit board assembly, a protective inner shell surrounding at least a portion of the printed circuit board assembly, and an outer shell surrounding at least a portion of the protective inner shell. The printed circuit board assembly has a printed circuit board, electronic components mounted to the printed circuit board, a battery mounted to the printed circuit board, and an interface compatible with a physiological characteristic sensor component. The protective inner shell is formed by overmolding the printed circuit board assembly with a first material having low pressure and low temperature molding properties. The outer shell is formed by overmolding the protective inner shell with a second material that is different than the first material.

An encapsulation for electronics is provided. The encapsulation includes a circuit card assembly (CCA) on which a component of the electronics is operably disposed, a compliant thermal buffer coating (TBC), thermoset material and high-performance thermoplastic materials. The compliant TBC is layered over the component and a first area of the CCA, which extends about a periphery of the component. The thermoset material is cast over the compliant TBC and a second area of the CCA, which extends about a periphery of the compliant TBC. The high-performance thermoplastic material is injection molded over the thermoset material and a third area of the CCA, which extends about a periphery of the thermoset material.

An object of the present invention is to provide a technique by which, when producing a resin molded article using an insert member having low pressure resistance, molding can be easily performed, and deformation of the insert member can be suppressed. A method for producing a resin molded article of the present invention, the method includes the steps of disposing an insert member in a cavity of a mold; performing injection of molten resin into the cavity; terminating the injection on and after the molten resin reaches an overflow portion in the cavity and before the molten resin fills the overflow portion; and separating resin in the overflow portion.

The present invention relates to a hybrid cowl cross bar manufactured through an improved method of performing an insert injection molding without applying hydraulic pressure to the inside of a metal pipe during injection molding in order to simplify a manufacturing process of a hybrid cowl cross bar and to secure rigidity of the cowl cross bar. According to an aspect of the present invention, a reinforcing material is inserted into a metal pipe that is a material of a cowl cross bar. The metal pipe may be made of a material such as aluminum, magnesium, or steel, like a conventional cowl cross bar. The reinforcing material may be manufactured by extruding a synthetic resin or a composite material (for example, PP+GF50%). A rib may be formed inside the reinforcing material to increase a capability to resist injection pressure when the metal pipe is insert-injected and to secure rigidity.

A unit cell of a fuel cell includes: an insert including a membrane electrode assembly and a gas diffusion layer; a foamed body disposed on an outer side surface of the insert; and a frame covering an outer side surface of the foamed body such that a polymer resin is injected to the outer side surface of the foamed body while the polymer resin partly penetrates into the foamed body.

The invention relates to a method for producing a radome, a flexible printed circuit board having a metallic structure being used. Said flexible printed circuit board is embossed and is back-molded with a thermoplastic material and electric contact elements are connected to the flexible printed circuit board. A connector skirt is placed on the contact elements prior to back-molding.

The present disclosure relates to a forming method for producing a composite part for an operating member, the method comprising the steps: disposing at least one permanent magnet in an injection-molding tool, which defines a mold cavity, and a heat-conducting reinforcement, which extends along the permanent magnet and is in touching contact with the injection-molding tool, in each case at a predefined position of the mold cavity; overmolding the permanent magnet with molding material by introducing molding material into the mold cavity; forming the composite part having the at least one permanent magnet, the heat-conducting reinforcement and the molding material.

A method for producing a sealing element on a gas diffusion layer of an electrochemical unit including the following is provided: arranging an injection molding tool on the gas diffusion layer; and introducing injection molding material into a cavity of the injection molding tool. The injection molding tool includes at least one deformation delimiting element, which delimits or prevents a deformation of the gas diffusion layer during the introduction of the injection molding material into the cavity such that damage to the gas diffusion layer is avoided and a sealing element with a mechanically stable connection region is produced.

An optical assembly of a light-emitting module, especially of a lighting and/or signalling module, for a motor vehicle, including an optical element, a frame; the optical element being overmoulded on the frame, the frame being shaped so as to make a mechanical attachment between the frame and the optical element following the overmoulding of the optical element on the frame.
