The back surface of the vibrating membrane is provided with a casing groove, which is sequentially embedded with the inner casing and the iron piece. A preparation method of a passive horn integrally formed by using liquid silicone rubber, under the condition of integrated injection molding, may improve the yield rate, ensure product quality, save assembly time and labor cost, and improve production efficiency.

A method of making an iridescent, vehicular trim assembly is provided that includes: molding a polymeric base comprising an exterior surface; and over-molding an element over at least a portion of the exterior surface. The element comprises a polymeric, translucent material and an exterior surface with an integral diffraction grating having a thickness from 250 to 1000 nm and a period from 50 nanometers to 5 microns. Further, the molding can be conducted such that the polymeric base is molded with a tint. The method can also include forming a plated region over the exterior surface of the base. In addition, the method can also include cleaning the plated region with a plasma-etching process before the over-molding.

A filter for a vent opening of a container comprises a housing and a filter element which are integrated by means of an injection molding process. A first part of the housing is formed by injection molding, after which a solid filter element and the first part of the housing are placed in a mold such that a circumferential edge portion of the solid filter element and the first part of the housing are adjacent to each other along a filling region. Material is injected against the solid filter element and the first part of the housing at the filling region, from which material a second part of the housing is formed after curing, hence forming the housing from the first and second parts of the housing and the filter element from the solid filter element. The filter element is rectangular.

A molded plastic part having a clear or translucent overmold and a substrate typically has a hard plastic substrate that can be opaque, translucent, or clear. The overmold is clear or translucent. Careful selection of materials provides for a substrate that retains its form after the thermoplastic overmold material, hot enough to flow, flows into the mold. A smooth area on the substrate provides a position for placing artwork.

A device (6) for producing injection-molded parts (1) is provided, with the device device (6) having at least one cooling device (9) in which pre-molded parts (4) are cooled before the injection-molding of a further material component (3). A method is also provided with improvements in the technical field of the production of injection-molded parts (1), in particular of brushes or toothbrush bodies.

Disclosed herein are microfluidic devices formed using a process comprising the step of disposing a planar barrier adjacent a surface of a molded base layer and positioned to overlay at least a portion of a microchannel provided therein, as well as lab on a chip device comprising: a base layer, a sensor disposed adjacent a first surface of the base layer, a cover layer disposed adjacent the first surface of the base layer to at least partially cover the sensor and a hesitation molded closing layer disposed on a second surface of the base layer opposite the first surface of the base layer, wherein the closing layer encloses at least a portion of the microchannel.

The present invention provides a sealing device for an opening. The device includes a body that has a first side and a second side. A passageway is formed through the body such that the passageway has a first end adjacent to the first side and a second end that is adjacent to the second side. A sealing member is provided that includes an outer gasket and an inner gasket. The outer gasket is positioned adjacent the first side and the inner gasket is positioned adjacent the second side. A seal connector connects the inner gasket and the outer gasket and the seal connector passes through the passageway. In this way, the inner gasket and the outer gasket are mechanically attached to the ring. The sealing device is configured for use in such applications as sealing the cargo opening on the deck of a kayak.

A wafer-level method for packaging a plurality of camera modules includes (a) overmolding a first housing material around a plurality of image sensors to produce a first wafer of packaged image sensors, (b) seating a plurality of lens units in the first wafer above the plurality of image sensors, respectively, and (d) overmolding a second housing material over the first wafer and around the lens units to form a second wafer of packaged camera modules, wherein each of the packaged camera modules includes one of the image sensors and one of the lens units, and the second housing material cooperates with the first housing material to secure the lens units in the second wafer.

An overmolding method for making thermoplastics articles of manufacture, for the perfumery and cosmetics fields, comprises the steps of: a) providing a first plastics material in a form suitable for an injection molding; b) providing an injection press, and molding by the injection press the first plastics material thereby providing a raw molded article of manufacture; c) associating with the raw article of manufacture made in said molding step: d) at least an insert element of a material different from the plastics material thereby providing an assembly of the raw molded article of manufacture and the insert element; and e) overmolding on the assembly at least a second plastics material thereby providing a finished molded article of manufacture.

A radio-wave transparent cover is configured to be arranged in a path of a radio wave in a radio wave radar device. The radio-wave transparent cover is made of a synthetic plastic molding product through which the radio wave passes. The molding product includes a first layer including a protrusion on a back side of the first layer and a second layer formed on the back side of the first layer. A back surface of the second layer includes gate marks formed when injection molding is performed. An area of the molding product for each one of the gate marks is less than or equal to sixteen square centimeters.
