A method of injection molding parts, including: injecting a first thermoplastic polymer into a first cavity; forming a ribbed structure comprising ribs in the first cavity, wherein each rib in the ribbed structure includes a microstructure on an outer portion of a rib; and reducing the surface imperfections in the part by overmolding a layer formed in the second cavity onto a portion of a rib by injecting a second thermoplastic polymer into the second cavity, wherein the overmolding occurs at an interface between the layer and the ribbed structure; or injecting a first thermoplastic polymer into a first cavity; forming a layer in the first cavity; and overmolding a ribbed structure comprising ribs formed in the second cavity onto a portion of the layer formed in the first cavity. In further variations gas is injected into a microchannel formed at the interface or a foaming agent is applied in the first thermoplastic polymer.

A method for producing a composite part. According to the method, a substrate is provided, the substrate having an integrated mixing portion for mixing a component system close to the substrate. The substrate provided is introduced into a cavity of a coating tool in an additional step. The substrate is then coated by flooding the cavity with the component system. The component system is mixed inside the cavity by means of the mixing portion of the substrate.

A method for manufacturing a decorative molding in which a transfer layer is transferred onto an injection molded product from a transfer sheet simultaneously with performing of injection molding in which at least one knockout pin in a second half-mold is caused to retreat to clamp a first half-mold and the second half-mold together; and the at least one knockout pin is made to advance so that the first half-mold and the second half-mold are released from each other until the second half-mold and the first half-mold open to a predetermined interval, while the transfer layer in a non-transfer area that is to remain on the transfer sheet is pushed against the first half-mold.

A light assembly and method of forming light assemblies includes a flexible light layer, a thermoplastic housing, and an IMC layer. The flexible light layer has a flexible substrate, a printed circuit, and a plurality of LEDs extending outward from the flexible substrate. The IMC layer is formed opposite the flexible light layer from the thermoplastic housing and covers the LEDs. Forming may include placing the flexible light layer within a mold cavity, injecting the thermoplastic structure on one side of the flexible light layer, and injecting the IMC layer on the opposite side of the flexible light layer from the thermoplastic structure. Injecting the thermoplastic structure into the mold cavity may change the shape of the flexible light layer. Datum features of the flexible light layer may align the thermoplastic structure relative to the datum features.

This method for manufacturing a resin structure (1) is provided with: a step for arranging a sheet (30) having a smooth surface (31) having a maximum height roughness of 3 μm or less, inside a forming mold (40) such that the smooth surface (31) faces an internal space (44) of the forming mold (40); a step for molding a resin molded body (10) to which the sheet (30) is adhered, by filling the internal space (44) with a resin; a step for separating the resin molded body (10) from the sheet (30), thereby forming a first region (11) having a maximum height roughness of 3 μm or less on at least a portion of the surface of the resin molded body (10); and a step for using a fluid conductive ink to form a wiring (20) on the first region (11).

A decoration member for a cosmetic container including: a color expression layer having a light reflecting layer and a light absorbing layer provided on the light reflecting layer; and a substrate provided on one surface of the color expression layer.

A switch structure includes a light-emitting part configured to receive power from a vehicle and to radiate light, a moving block located so as to surround the light-emitting part, a light-transmissive part configured to allow light radiated from the light-emitting part to pass through an opening in the moving block, and a film-printing layer located on a top surface of the light-transmissive part and including a symbol.

The invention relates to an injection moulding machine having a coating installation, wherein the injection moulding machine has at least one fixed platen and one movable platen for the fastening of mould tool halves of at least one mould tool, and the coating installation has first pressure-generating and/or first pressure-conducting means for coating components at a first, relatively low pressure level and second pressure-generating and/or second pressure-conducting means for the coating components at a second, relatively high pressure level, wherein at least all second pressure-generating and all second pressure-conducting means are coupled to the movable platen so as to be jointly movable along a movement path of the movable platen.

The improved mold assembly for cultured marble molding is provided. The mold assembly can comprise a male mold portion and a female mold portion. The assembly can further comprise a molding tool. The molding tool can have a side wall having an upper curved s and a lower curved portion. The molding tool can be constructed from a flexible and/or soft material. The lower curved portion of the molding tool can be coated with a gel coat having a first color. The molding tool can facilitate molding of a countertop having a recessed bowl portion having a color different from a counter portion of the countertop.

A method for manufacturing a blinker module for a rearview device of a motor vehicle includes the steps of providing at least one lighting element comprising at least one light guide and at least one light disk or lens and providing of at least one illuminant unit comprising at least one illuminant, wherein the illuminant unit is designed to couple light emitted by the illuminant into the lighting element. A blinker module, rearview device and motor vehicle, including the blinker module manufactured according to the method, are also described.
