The protrusion is fitted to the first molded portion. A light source mounting substrate is disposed on the back surface side of the resin panel. At least a light source of the light source mounting substrate is sealed by the second molded portion. An integrally molded product of the light source mounting substrate and the second molded portion is filled and solidified at a low pressure while compressing a cavity of a molding mold.

A black polyester film and a method for manufacturing the same are provided. The method for manufacturing the black polyester film includes: providing a recycled polyester material; physically regenerating a part of the recycled polyester material to form physically regenerated polyester chips having a first intrinsic viscosity; chemically regenerating another part of the recycled polyester material to form chemically regenerated polyester chips having a second intrinsic viscosity lower than the first intrinsic viscosity; mixing black regenerated polyester chips, the physically regenerated polyester chips, and the chemically regenerated polyester chips according to a predetermined intrinsic viscosity so as to form a polyester chip raw material; melting and then extruding the polyester chips raw material to form the black polyester film having the predetermined intrinsic viscosity.

A method of multi-shot injection molding of a decorative part for a front-end of a vehicle includes performing a first injection molding shot of a transparent plastic material to form an A-side portion of the decorative part and performing a second injection molding shot of an opaque elastomeric material for form a B-side portion of the decorative part. A multi-shot injection molded decorative part for a front-end of a vehicle includes an A-side portion formed by performing a first injection molding shot of a transparent plastic material and a B-side portion formed by performing a second injection molding shot of an opaque elastomeric material.

A method of for multi-shot injection molding of a transferred part with film decoration includes performing a first injection molding shot to form an opaque plastic portion and a protective film layer that collectively form a transferred part defining one or more apertures, and performing a second injection molding shot including the transferred part to form a transparent plastic portion on an A-side of the transferred part and a metallic film layer on a B-side of the transferred part. A multi-shot injection molded transferred part with film decoration includes an opaque plastic portion and a protective film layer that collectively form the transferred part defining one or more apertures, a transparent plastic portion on an A-side of the transferred part; and a metallic film layer on a B-side of the transferred part.

A molded component displays an optical image that is visible from a front by allowing light that is emitted from a light source that is disposed at a back to pass therethrough. The molded component includes a light-shielding resin member that has an optical transmission hole that has a shape depending on the optical image in a plan view, and a transparent resin member that is optically transparent and that is stacked on a surface of the light-shielding resin member that faces the front such that the transparent resin member covers at least the optical transmission hole. The transparent resin member includes a peripheral portion that has a constant thickness, and a thin portion that is disposed inside the peripheral portion and that is thinner than the peripheral portion.

A method of manufacturing a plastic glazing of a tailgate of a vehicle, the method comprising: injecting a first material into a molding apparatus to form a first component of the plastic glazing, wherein the first component comprises a panel of the plastic glazing; injecting a second material into the molding apparatus to form a second component of the plastic glazing, wherein the second component combines with at least the first component, wherein at least a portion of the first component and the second component comprises a transparent cover of a molded light assembly; and injecting a third material into the molding apparatus to form a third component, wherein the third component combines with at least the first component.

Multi-body interpenetrating lattices comprise two or more lattices that interlace or interpenetrate through the same volume without any direct physical connection to each other, wherein energy transfer is controlled by surface interactions. As a result, multifunctional or composite-like responses can be achieved by additive manufacturing of the interpenetrating lattices, even with only a single print material, with programmable interface-dominated properties. As a result, the interpenetrating lattices can have unique mechanical properties, including improved toughness, multi-stable/negative stiffness, and electromechanical coupling.

A method of making an integrated depth sensor window lens, such as for an augmented reality (AR) head set, the depth sensor window lens comprising a sensor lens and an illuminator lens separated by an opaque dam. The method uses a two-shot injection molding process, a first shot comprising an optically clear polymeric material to form the sensor lens and the illuminator lens and the second shot comprising an opaque polymeric material to form the separator of the two.

An implement having a base structure with a core component and a shell component that surrounds the core component. The core component may include a body formed of a rigid material and decorative elements embedded within the body. The shell component may be formed of a substantially transparent material so that the decorative elements of the core are visible through the shell component.
